What is the best way to remove an existing finish? Are you cleaning or stripping concrete, wood or metal finishes?
The method you use will depend on the material you are stripping.
What is Media Blasting?
Media blasting is a surface restoration method that does a quick job of removing most paints and stains, rust, scale or gum from hard surfaces. It incorporates a blasting unit that projects compressed air with abrasive material such as walnut shells, corncob grit, sharp metal media, dry ice pellets or crushed glass at high speeds onto the surface.
The advantages of this system are that it is fast, cost-effective, and environmentally safe. Since it uses no hazardous chemicals it can be used safely in urban areas. There is little chance of water contamination since blasting media consists of organic materials or crushed glass. It does not change the PH balance in water or soil making it a 100% environmentally-friendly.
Our choice of blasting media at SignLITE is crushed glass. This recycled material is one of the most versatile general-purpose abrasives, gently removing layers of paint, grease, graffiti or rust without causing surface damage.
Though it is safe, media blasting is not a DIY project. Talk to an expert before you pick up a blasting gun yourself!
What is Chemical Stripping?
Chemical stripping incorporates chemical strippers to dissolve and remove paint, sealants, rust and grease. While the end result can be a beautiful smooth finish, it is messy, and can take a while. Most chemical strippers come in gel form, allowing them to stay in place and dry slowly. This is particularly useful for wood surfaces that include intricate carvings.
Apart from protective clothing, no special equipment is needed. While it may be user-friendly chemical stripping is not so kind to the environment. Most common chemical strippers are solvent-based and typically contain methylene chloride. Methylene chloride is a strong oxidizer, flammable and very reactive. Rubber gloves, long sleeves, mask and respirators need to be worn. Used clothing items, rags and any residue need to be safely discarded.
However, biochemical strippers based on oils from natural materials such soybeans, pinesap, or citrus trees are growing in popularity. Cleanup is with water and leaves a nice citrus smell. Newer blends of solvents keep safety in mind and will break down paints and resins leaving a clean dry finish with the no final rinse required.
There are many residential and commercial surface restoration applications for media blasting or chemical stripping such as:
Concrete, Brick or Stone
Cleaning stamped concrete driveways
Exterior or interior brick or stone walls, or patios
Fire, smoke, water or mould restoration
Cleaning graffiti, gum & grease
Pole lights and pylon signs
Heavy industrial, vehicles and machinery
Small industrial – brass, bronze, copper and aluminum
Log home restoration
Wood furniture or wooden structures

You might not pay them much mind, but the bright lights hanging above parking lots are a major part of our urban landscapes. A survey by the Canadian Urban Institute counted between 1.4 and 2.7 million parking lot luminaires installed in Ontario alone!
Well-designed parking lot lighting makes life better for everyone: it lowers the risk of accidents and property damage while providing employees and customers with a sense of safety and security.
But great lighting design isn’t just about putting lights on a pole. Smart, effective parking lot lighting provides exactly the right amount of light in exactly the right location using as little energy as possible.
For standards not addressed by local by-laws, the Illuminating Engineering Society (IES) provides guidance in the form of parking lot lighting best practices. The IES monitors and controls the standards and illumination guidelines in the North American lighting industry.
Quantity vs. Quality of Light
If your goal is to enhance visibility in the lot, simply replacing your current lights one-to-one with brighter ones might not be the solution. More light doesn’t necessarily equal better light. The quality of your parking lot lighting is just as important as the quantity.
More intense exterior lighting might increase visibility in one area, but it can also make it harder to see people and vehicles in the darker areas. Good lighting aims to decrease the contrast between light and dark areas and distribute light evenly across the space.
A well-designed parking lot creates a welcoming environment for shoppers and clients while doing the opposite for unwelcome characters. By allowing personnel and security cameras to keep watch, lighting deters property damage and other illicit activity.
This is another reason why lighting consistency matters: too much contrast or glare makes it difficult for people and surveillance equipment to properly observe the area.
Areas with high traffic (especially a mix of pedestrian and vehicle traffic, like crosswalks) do often require higher levels of light, but it is just as crucial to avoid glare and contrast in these areas. A lighting installation professional can help you select the proper luminaries and fixtures for the various parts of your property.
It can be hard to sleep when it’s bright outside, whether the brightness comes from natural light or the neighbouring parking lot.
The intrusion onto neighbouring properties (known as light trespass or spill light) is preventable through good lighting design. LED parking lot lights provide superior directional lighting and less spill than other high-bay lighting solutions. For fluorescent, metal halide or high-pressure sodium luminaires, shields can be added to block the light in certain directions.
Additionally, high-bay lights should be mounted no higher than the buildings or trees at the perimeter of the property.
Energy consumption is power multiplied by time. Reducing consumption requires that you reduce either the duration the lights are on or the energy they consume.
Fortunately, modern lighting controls have made it easier than ever to control both parts of the equation. Incorporating lighting controls at the same point you select your luminaires can help you maximize the efficiency of your parking lot lighting.
There are several lighting control solutions available for parking lots, including photosensor-based (adjusting light level depending on the amount of sunlight) and timeclock-based (adjusting light level at a set time) systems.
The term ‘media blasting’ encompasses a diverse range of methods and technologies. Although we here at Sign LITE specialize in on-site property restoration, people also use various forms of media blasting for metal finishing, vehicle restoration and more! Here’s a quick summary of the media blasting terminology you’ll encounter when it comes to our area of expertise.
Blasting media, also known as the abrasive or grit, is the material used in the media blasting process. Media comes in many kinds of materials shapes and sizes, and choice of media can have a significant impact on the results.
Media is often categorized according to its shape, size, hardness and density. Organic materials like walnut shells and corncob are great for fragile surfaces like hardwood; sharp metal media like aluminium oxide is often used for heavy-duty cleaning and etching; smooth, rounded media like sheet shot is ideal for peening metal.
Recycled crushed glass is our media of choice since it delivers an even, clean finish and is suitable for treating a range of surface materials. Crushed glass is angular but not sharp, and it produces minimal dust. This material is also inert and non-toxic.
The blasting unit is the equipment used by an operator to project compressed air and media onto a surface. The set-up varies across industries and applications. For parts finishing and equipment restoration, operators often used fixed blasting units connected to a cabinet designed to contain dust.
Since we restore surfaces on-site, Sign LITE uses a smaller, self-contained media blasting unit that can reach locations up to 200 feet away from its power source. A portable unit consists of a handheld apparatus or ‘gun’ connected to a compressor, a hopper that feeds blasting media, and a power source. The operator can adjust the flow of air and media.
Interior Media Blasting
Interior media blasting is the process of cleaning an interior surface, such as concrete floors, brick walls or metal fixtures, using media blasting. In the hands of a trained professional, certain blasting methods can be used indoors safely.
Wet blasting using crushed glass media is ideal for interior media blasting, as it produces minimal dust and is non-toxic.
Media blasting, also known as abrasive blasting, is a process by which a material is projected at high speeds onto a surface. The material (media) is propelled by the force of compressed air, water, or a combination of the two. It is cost-effective and environmentally safe, employing recyclable materials and no hazardous chemicals.
We use media blasting to means to remove rust, scale, paint, graffiti, gum, or other damage or deterioration from hard surfaces. Different types of media are suitable for different jobs – we’ve found crushed glass media ideal for cleaning pole lights, pylon signs, brick, concrete and many steel surfaces.
Watch the media blasting process in action:
Sandblasting refers to media blasting using actual sand as the blasting media. Although the terms ‘sandblasting’ and ‘media blasting’ are sometimes used interchangeably, it’s important to recognize the differences between the various methods. Sandblasting poses greater occupational and environmental hazards because it disperses silica; today, most contractors have moved towards safer alternatives like crushed glass as the medium.
Also known as hydro blasting, wet blasting is a media blasting method that produces less dust. Although it is not truly ‘dustless’, wet blasting significantly reduces the amount of dust by combining the media with water (either by moistening the media prior to blasting or dispersing water through the blasting nozzle).

Can you tell luminance from illuminance? Colour temperature from colour rendering? These are some of the terms you’ll encounter when it comes to installing outdoor lighting. Below, we’ve defined the must-know outdoor lighting terminology, including:
Colour-rendering index (CRI) measures how accurately a light source shows the colours of objects it illuminates compared to natural light. For example, the maximum potential CRI value is 100; the standard value for parking lot lighting is 65. CRI is important in outdoor lighting for spaces like car dealerships, where the colour of the products can have a significant impact on a customer’s decision to buy.
Colour Temperature and Correlated Colour Temperature
Colour temperature describes the colour appearance of a light source. With incandescent lamps and other thermal radiators, colour temperature corresponds with the actual temperature of the light source.
When it comes to gas lamps and solid-state lighting, where the temperature has no relation to the colour of light, colour temperature is measured by comparing the appearance to the light of a thermal radiator. The technical term for this is correlated colour temperature.
Colour temperature is measured in Kelvins (K). For example, the flame of a candle emits yellow light at a temperature of approximately 2,000 K; the filament of an incandescent bulb is yellow-white at 2,700 K; the sun at noon appears at around 5,000 K.
Efficacy describes the energy-efficiency of a light source based on the ratio between its luminous flux and power consumption.
Efficacy is measured in lumens per watt (lm/W). For example, a typical fluorescent lamp is 10 lm/W; a high-flux LED is 120 lm/W.
Luminous flux, or lumens, describes the amount of light a light source radiates each second under standard conditions. It is among the most common (and commonly misunderstood) measurements listed in lighting datasheets and packaging. Lumens do not describe the colour or intensity of light; only how much light the source emits.
Luminous flux is measured in lumens (lm or Φ).
Glare is an effect that occurs when the light is too bright compared to its background, light causing discomfort and reducing the ability to see. Though there are methods of calculating and predicting glare, glare it is also subjective; for example, senior citizens may have more difficulty adjusting to glare than younger viewers.
With consideration in lighting design, glare can be reduced and controlled through proper luminaire placement and use of cut-off fixtures and shields.
Illuminance measures the amount of light that falls on a surface. This measurement has largely replaced terms such as foot-candles, illumination value and illumination level. It is typically described regarding ratios of maximum-to-minimum and average-to-minimum illuminance in an area. Measuring illuminance is necessary to calculate other measurements like luminance and glare.
Illuminance is measured in luxes (lx), with one lux equalling one lumen of incident light per square metre of light-receiving surface. For example, a typical bright summer day is approximately 100,000 lux; an overcast sky would clock in at 5,000 lux; a living room may have 100 lux. One foot-candle is equal to 10.76 lux.
Luminance measures the intensity of light emitted by an object or surface. This measurement can apply to light that emits from a lamp or luminaire or a surface that reflects or transmits light, such as a window or road surface. Usually, luminance is measured from the perspective of an observer looking towards the lighted area.
Luminance is measured in candelas per square metre (cd/m2). For example, an office desk might reflect 100 cd/m2 of a desk lamp’s light; a typical fluorescent lamp may emit luminance of 5000 to 15,000 cd/m2; the surface of the sun has a luminance of 1650 cd/m2.
Luminous intensity measures the amount of light (the lumens or luminous flux) per second emitted in a specific direction.
Luminous intensity is measured in candelas (cd).
Watts (W) measure the amount of energy a lamp consumes to produce light. The lower the wattage, the less energy the lamp requires. With incandescent lamps, and a lamp with higher wattage produces more light; however, that is not the case with compact fluorescent lamps nor LEDs.
Types of Outdoor Lighting and Outdoor Lighting Components
A ballast is a device that controls the electrical current used to produce light in a gas discharge lamp such as a fluorescent light. If the ballast fails, the lamp can overheat and burn out.
A bollard is a type of lighting fixture that includes a short, ground-mounted post topped with a light source that is directed downward.
A driver controls the electrical current in a solid-state lamp, ensuring a consistent voltage level as the number of LEDs in the circuit increases or decreases. The driver will increase or decrease the voltage as necessary to maintain a constant current.
A type of lamp that produces light inside a transparent, gas-filled tube. Each end of the lamp is sealed with an electrode: one positively-charged (the anode) and the other negatively-charged (the cathode). When the light is switched on, voltage travels between these two electrodes, and fast-moving electrons collide with gas molecules to produce light.
Fluorescent lamps are approximately eight times as efficient as incandescent lamps and last far longer.
Halogen Incandescent Lamp
A type of lamp that produces light by heating a filament inside of a gas-filled bulb. The difference between a halogen incandescent and normal incandescent lamp is a reaction between the halogen gas and evaporated filament material – part of the evaporated material returns to the filament, prolonging the life of the lamp. As a result, incandescent halogen lamps have a considerably longer lifespan than normal incandescent lamps, lasting between 1,000 and 6,000 hours of use.
A type of lamp that produces light by heating a filament inside of a bulb. Only 5% of the energy an incandescent bulb uses goes towards producing light, while the rest produces heat. Because of this, incandescent lamps are largely recognized as the least energy-efficient forms of outdoor lighting.
Since the filament evaporates over time, incandescent bulbs have a relatively short lifespan compared to other types of outdoor lighting, lasting around 1,000 hours of use at most.
Light-Emitting Diode (LED)
A light-emitting diode (LED) is a tiny microchip containing semi-conductive material that produces light by applying a voltage to an electrical junction. Different types of semi-conductive materials produce different colours of light, making it possible to produce a wide range of different colour LEDs. If the chip or cluster of chips is encapsulated in a bulb, it is an LED lamp.
The technical term for a light fixture or light fitting; in other words, the apparatus containing a light source.
A reflector reflects, refracts, absorbs or transmit lights to efficiently direct the light emitted from the bare lamp. It may be a part of the luminaire or the lamp itself, or a component added separately during or after installation. Reflectors are important in the types of outdoor lighting that require precise light control, such as floodlights, spotlights and road lights.
Solid-state lighting is a general term for electronic light sources using solid, semi-conductive material. Light-emitting diodes or LEDs are a type of solid-state lighting.
Lighting Design Principles
Mounting Height (MH)
The vertical distance between the base of a pole and the luminaire; or the ground and the luminaire, in the case of a wall-mounted light.
Light pollution, also known as an uplight, refers to light unnecessarily directed upward into the night sky. Excessive light pollution creates an unnatural glow that masks the view of the sky from the ground. Effective outdoor lighting design uses shields, hoods and other devices can reduce or eliminate skyward lighting.
Light trespass, also known as a backlight, refers to light spilling into unwanted areas like adjacent homes or properties. It can be avoided through careful lighting design, including proper location, mounting and shielding of luminaires. Many cities have by-laws limiting the level of light allowed near property lines to reduce light trespass.
Ask an Outdoor Lighting Installation Expert
When it’s done right, outdoor lighting can boost visibility, increase safety and enhance the night-time environment overall. Poor lighting design, on the other hand, can result in excessive glare, wasted energy and complaints about light pollution and light trespass. Ask an expert on outdoor lighting installation before you embark on your next big lighting project.
Maintenance matters, even when it comes to your property’s parking lot. Curb appeal is part of it, of course, but that’s not all. Potholes, puddles, crumbling pavement and dark corners can raise a host of safety issues that leave your business open to liability.
Not sure where to begin? Here are a few cost-saving tips that’ll help you keep your parking lot in impeccable shape.
1. Sweep it Clean
From the customer’s view, the state of the lot speaks volumes about your overall management. A tidy lot with good maintenance and beautiful landscaping shows you aim to please from the moment they step onto your property.
Start with a clean sweep, clearing leaves, dirt and debris on a regular basis. Not only does this make the property look neat and tidy, but it also helps you spot problem areas like cracks and oil stains. Next, get rid of crumbling parking curbs and barriers before they become a safety hazard. Lawn care is just as important – the parking lot will only look as clean as the green space that surrounds it.
2. Care for the Tarmac
Asphalt takes a beating here in Southwestern Ontario. It bears the brunt of UV rays, heavy rain, and snow, not to mention our love of 2-ton pickup trucks.
Over time, the combined forces of water, oxidation and fluctuating temperatures cause parking lot surfaces to break down. What starts as a small crack in the pavement will gradually bloom into migrating cracks, degrade the asphalt sub-base and allow potholes to form.
It pays to have these cracks filled and sealed before they have a chance to expand. Patching up holes on an annual basis is far cheaper than having to replace major portions of the pavement down the line!
3. Upgrade to LEDs
How many people does it take to change a lightbulb? When you’re talking overhead lighting, you might need more than your usual parking lot maintenance crew. The cost of replacing a burnt-out parking lot light is often greater than you would expect, especially if you have to hire outside help.
That’s the beauty of LED lights. Along with providing better visibility and using less electricity than halogen bulbs, LED lights have a much longer lifespan. They’re also impressively durable and weather-resistant, performing just as well in the dead of winter as they do in warmer months.
Depending on your existing parking lot light fixtures, upgrading to LED parking lot lighting could involve a straightforward retrofit or a more extensive installation. In either case, the fact that LED lighting requires less ongoing maintenance and uses less energy means fast payback.
4. Keep Your Lights Clean
While you’re contemplating an LED parking lot lighting upgrade, ask yourself: when was the last time someone went up to clean those fixtures?
Outdoor lighting accumulates mountains of dirt, grime, and insects. The dirtier they are, the less light they provide. By some estimates, cleaning your lamps can make them 20-30% brighter! That’s up to 30% more light for the same energy cost.
5. Eliminate Graffiti Fast
When a property sits unoccupied, it becomes a magnet for graffiti. Why? Because vandals know no one’s watching. How? They see that the last person’s graffiti hasn’t been touched.
Vandalism is contagious, and that’s why it’s crucial to stay on top of it. When someone tags your property, have someone remove that graffiti as quickly as you can. If it reoccurs, take steps to make your parking lot less appealing to potential vandals.
Just about every parking lot maintenance issue has one thing in common: the sooner you notice it, the easier it is to fix.
Potholes don’t happen overnight – a crack in the asphalt is much easier to repair than a full-blown hole. Graffiti does happen overnight, but if you scrub it right away, you’re less likely to find more graffiti the next day.
Preventative maintenance is key. Ensure that someone on staff inspects the lot from end-to-end on a regular basis, looking for small cracks, oil stains, standing water, graffiti, and dead lights.
Concrete is tough, but it’s also porous. Without a protective topcoat like epoxy, a concrete floor will readily absorb paint, oil and other liquids several millimetres deep into its surface. Careless driving on a concrete surface can also result in tough-to-remove tire marks.
The good news is, it is possible to get most stains out of a concrete floor if you take the right approach.
There are several ways to go about removing paint, oil and tire marks from a concrete floor. For smaller stains, you can usually start with the low-tech approach and step it up if necessary; for tough jobs, you might want to bring out the blasting guns from the beginning.
Removing Paint from a Concrete Floor
The fresher the paint, the easier it is to remove. But even a long-hardened stain doesn’t have to be there for good. With the right tools and techniques, it is possible to remove paint from concrete’s porous surface.
Method 1: Media Blasting
Contrary to popular belief, it is safe to use a blasting gun indoors with proper choice of techniques and equipment and blasting media. Media blasting can completely remove large paint stains from a shop, garage or factory floor without damaging the underlying concrete. Though the process does leave behind some dust and residue, the floor underneath is a clean slate for sealing or re-painting.
Paint remover (or paint stripper) is a compound designed to remove paint and clean the underlying surface. Although some manufacturers have introduced non-toxic paint removers (such as soy-based gel products), most products on the market contain harsh chemicals. You should only use a chemical paint remover in a well-ventilated area while wearing safety glasses, rubber gloves and rubber boots.
Removing paint from a concrete floor using paint stripper is a surprisingly arduous process (you cannot simply pour it on and wait.) As a result, this method is best used for paint stains with a small surface area.
Remove any loose paint with a wire brush or putty knife and sweep it away from the area.
Apply the paint remover. The correct type of remover depends on the type of paint in question; when in doubt, use an oil paint stripper.
Let the remover to work its way into the concrete floor. Check the manufacturer’s instructions on how long to wait.
Wearing protective gloves, scrub the stain with a wire brush or putty knife to remove the loosened paint.
Depending on the depth of the stain, this process may have to be repeated two to three times in order to completely remove the paint from your concrete surface.
Removing Oil Stains from a Concrete Floor
Forgot to put down a catch pan during your last oil change? It happens, and it’s not pretty. Oil is among the most stubborn stains to remove from concrete, but it’s important to do, because that oil can eventually seep back to the surface and ruin your next paint or sealing job.
Method 1: Detergent
If you notice the oil stain while it’s new, it may be possible to remove through the application of a strong detergent, warm water, a stiff brush and lots of elbow grease. Start by blotting the stain with a rag or paper towel to absorb loose oil (dab, don’t rub, to avoid spreading it). Next, apply a detergent and scrub the stain with a brush soaked in warm water.
Method 2: Absorbent Material (Poultice)
A poultice is an absorptive material (like sawdust or kitty litter) saturated in a solvent (like acetone, xylene or lacquer thinner) that is placed on the concrete surface and covered in plastic wrap. Through the process of osmosis, the concoction breaks down the spilled oil and ‘pulls’ it out of the floor. It’s time-consuming, but it works, especially for small, fresh stains that haven’t had time to set.
Method 3: Media Blasting
For serious oil stains that have stood the test of time, media blasting is your best bet for removal. A blasting system uses pressured air (and water, in the case of wet blasting) to propel an abrasive material at the floor and strip off surface-level stains. Media blasting is gentle on the underlying concrete surface (which, though durable, is porous and easily scratched), making it ideal for property users who plan to paint or refinish the floor afterward.
Removing Tire Marks from a Concrete Floor
A driver came in fast and didn’t quite stick the landing; now, you’re stuck with tire marks on the floor. Fortunately, it doesn’t have to be there for good. Removing tire marks from concrete is a simple task.
Method 1: Pressure Washing
If the concrete floor is rated for pressure of 4000 psi, pressuring washing is an option for removing rubber markings. Set the water to a pressure of 3000 psi and a temperature high enough to produce steam.
Method 2: Media Blasting
Passing over the floor with a blasting gun can take the tire marks right off. Since the rubber will not have penetrated the concrete as deeply as paint or oil, it should take only a light touch with a fine blasting media to remove tire marks from the floor.
Method 3: Degreaser
Soak the tire marks in an industrial-strength degreaser (available at most hardware or auto supply stores). After 10 minutes of soaking, scrub using a stiff-bristled brush. Clean the loosened rubber with a sponge and warm water. Be sure to let the area dry completely before parking on it.
However, people who see the property for the very first time are bound to notice its flaws, especially those who are scrutinizing it as a prospective buyer. Even minor faults could raise questions about the costs of restoration.
Is it feasible to remove that graffiti, or will we have to paint over it?
What will it cost to strip and restore that rusted railing?
If the owner hasn’t bothered to replace a light, what does it say about their care for the rest of the property?
As a seller or manager preparing a commercial property for sale, you should endeavour to view the condition of the property with fresh eyes. Think of the impression it makes on someone seeing it for the first time.
Making a small investment in exterior repairs and restoration can go a long way when it comes to winning over buyers.
2. Cost of Upkeep
Energy expenses can be substantial here in Southwestern Ontario, even for small businesses.
Prospective commercial property buyers pay close attention to the efficiency and overall condition of any appliances, lighting, and other building systems that come with it. It counts as a strike against the property when the equipment is outdated or inefficient.
On the other hand, energy-efficient appliances and lighting can be a strong selling point.
Upgrading a property’s heating, cooling, and lighting systems can significantly increase its value and reduce risk in the eyes of a buyer.
That’s one of the last things you want prospective buyers to contemplate when they see your property.
Having a clean, brightly-lit parking area is a big point in favour of any commercial property.

Ever wished you could clean up an interior wall the way people blast away graffiti outdoors? Good news: interior media blasting not only possible but highly effective and affordable.
We know what you might be thinking. What is interior media blasting? Is it safe to media blast indoors? Doesn’t it make a mess?
If you haven’t seen the results first-hand, these questions are understandable. Most people are only familiar with water-blasting (and media blasting in general) when it comes to outdoor fixtures like walls, fences, and concrete slabs.
Interior media blasting isn’t as well-known as its outdoor counterpart, but it’s just as effective and increasingly popular for commercial and industrial properties.
Here’s what interior media blasting and water-blasting indoors is all about.
What is Indoor or Interior Media Blasting?
Media blasting refers to the process of cleaning a surface by blasting it with pressurized air and a fine, abrasive material (sometimes, water is added to the mix as well). The force of the air/water and the abrasiveness of the blasting media strips the surface of paint, rust, dirt, and other imperfections — all while leaving the original base intact.
Blasting is effective in restoring the surface of concrete, stone, brick, and metal surfaces, along with certain woods and hard plastics. Some of the most common uses for media blasting include graffiti removal, paint stripping, and rust removal.
Interior media blasting is just as it sounds: using blasting equipment to clean surfaces inside a building. Its primary applications are in commercial and industrial property restoration. Property owners and managers choose interior blasting when there is a need to clear away old paint, rust, oil, and other blemishes from walls, flooring and large fixtures in preparation for sale or restoration.
Is it Safe to Media Blast Indoors?
Although not as common as outdoor blasting, it is safe for a trained professional to use media blasting equipment indoors. However, not all blasting methods are intended for indoor use, so it’s important to choose the correct equipment and blasting media.
For interior media blasting in Southwestern Ontario, we use a small, portable wet abrasive blasting system with crushed glass media. Having employed these methods for years, we are confident that this form of media blasting is safe for industrial and commercial use.
Water-blasting, which combines blasting media and water, produces little to no dust.
Crushed glass media is completely inert, non-hazardous, and non-toxic. It poses no danger to people or animals.
Crushed glass media is not sharp and does not leave behind residue on the surface.
In short, it is safe to media blast indoors using the right equipment in the hands of a trained professional.
Is Interior Media Blasting Messy?
We won’t lead you to believe that water-blasting is entirely mess-free, but we do believe it’s better than the alternative. Here’s why.
Interior media blasting is a fast, effective way to clean brick, concrete, metal, and other surfaces. It does require some clean-up since it’s necessary to sweep what remains of the stripped material (paint, rust, etc.).
However, this is safer and less time-consuming than alternatives such as chemical strippers or power sanders. And considering the affordability of media blasting, we find many property owners and property managers prefer the blast-and-sweep approach.
Applications of Interior Media Blasting
Interior media blasting can remove surface finishes and imperfections from walls, flooring, and fixtures made of:
Our clients for interior media blasting include commercial and industrial property owners, realtors preparing properties for sale, restoration companies, and property management companies. Some of the possible applications include:

One of our team’s specialties is media blasting: a fast graffiti and rust removal method that involves spraying the surface with a mixture of water and abrasive material. Our choice of abrasive (or ‘blasting media’) at SignLITE is recycled glass. Why? Allow us to explain the many benefits of crushed glass media blasting for graffiti removal and rust removal.
What is Crushed Glass Media Blasting?
Media blasting is widely used as a way to clean and restore walls, fences, decks, and other exterior surfaces. It is also popular among car enthusiasts as a way to strip paint and rust from the body of a vehicle for restoration. At SignLITE, we primarily use portable media blasting equipment to rescue commercial properties from beneath layers of paint, grease, graffiti, and rust.
Our system is what’s referred to as wet abrasive blasting or hydroblasting machine: it uses compressed air to propel a mix of water and crushed glass against the surface of the object to be cleaned. The glass strips the surface, while the addition of water cuts down on dust (a benefit we’ll say more on below).
Why crushed glass? In short, crushed glass media blasting is fast, gentle, safe, sustainable, and mess-free. Each of these benefits are worth exploring in more detail.
Fast Graffiti and Rust Removal
Time is money. When a business owner needs a wall clear of graffiti, or a deck ready for staining, they want it done fast. As a general-purpose abrasive, no other material matches the effectiveness of crushed glass. It cuts through rust, paint, and oil fast, covering a lot of ground in minimal time.
Crushed glass media blasting is tough on blight, but gentle on the underlying surface. In addition to tough rust and graffiti removal jobs, it is a suitable for restoring the original appearance of sensitive surfaces like wood, concrete, stainless steel, and fibreglass.
With crushed glass, property owners don’t have to worry about expensive touch-ups or extra restoration work after the job is done.
The advantage of hydroblasting (wet blasting) is that it all but eliminates dust from the equation. Unlike alternatives like sodablasting, which leaves a messy residue behind on the surface, hydroblasting with crushed blast leaves no mess. That means no extra clean-up work for property owners to deal with.
Since there’s no dust or chemicals involved, this method of graffiti and rust removal is safe to use around people and animals. Business owners will be relieved to know they won’t have to shut down for the day in order for us to do our job.
Sustainable and Environmentally-Friendly
Crushed glass media blasting is the greenest way to remove graffiti. Being inert, non-toxic and non-hazardous, this choice of blasting media poses no danger to the natural environment. Plus, it’s sustainable: all the crushed glass we use comes from recycled bottles.

Take these steps to keep vandals off your property and prevent graffiti from reappearing.
1. Remove Graffiti Fast
Take a walk through any urban centre and you’ll notice a trend: where one vandal has left their mark, others have followed. Left alone, graffiti will invariably become a magnet for more vandalism because it sends the message that people can get away with it.
That’s why it’s important to remove any and all graffiti from your commercial property as soon as possible after it appears. When taggers see that their message will be gone from your property in no time, they’ll be less inclined to pay you a second visit.
The fastest way to remove graffiti is to treat the surface with a media blasting process. Media blasting is often referred to as sandblasting, but it doesn’t involve sand – rather, it employs a mixture of pressurized water and recycled glass to strip away spray paint without damaging the surface beneath.
Media blasting works on brick, stone, concrete and asphalt, as well as metal fixtures like signs, lamp posts and dumpsters.
2. Keep Your Commercial Property Clean
Graffitists tend to target properties that already look dilapidated. If the paint is already peeling and the fences are falling down, vandals will correctly assume that the property owner lacks the time or resources for upkeep.
Vandals use things like outdoor benches, garbage bins, and dumpsters as a stepping stool to access and deface areas that would normally be out of reach, like your rooftop, exterior light fixtures, and electric signage. You can stop these objects from becoming an accomplice to vandalism by bolting them to the ground in a spot that is not adjacent to attractive surfaces.
4. Use Plants as a Barrier
Graffiti is often a crime of opportunity – vandals see a bare wall that is easy to reach and seize the opportunity to make their mark. Adding obstacles can effectively deter all but the most determined graffitists. One of the easiest ways to do this is to plant shrubberies, vines, or other vegetation around your building – which have the added bonus of beautifying your property at the same time.
5. Upgrade Your Exterior Lighting
Darkness is a graffiti artist’s ally. If you’re having problems with graffiti, boosting your exterior lighting with LED retrofit services is definitely a worthwhile investment. LED lights are brighter, more durable, and longer-lasting than fluorescent and halogen lights, providing greater coverage of your property at night.
If you don’t want to keep the lights on all night, you can also outfit LED lights with motion detectors.
