How to Apply an Epoxy-Coat to Your Garage Floor

Garages can be messy places. Although the concrete flooring in the garage is durable enough, the messiest of activities, the paint coating on the concrete may still be compromised.


All it takes is some oil or grease falling onto the concrete for the paint to get ruined. However, if you paint an epoxy coating onto your garage floor, it will protect the concrete, allowing you to clean it and keep it looking shiny and vibrant.

Epoxy coatings are made of a synthetic resin material, which makes them non-hazardous and completely safe to use on your garage floor.


The trick is knowing how to properly apply the epoxy coating. It is not as simple as taking a paintbrush and just rolling the coating solution onto the floor. You need to take the necessary precautions and follow the proper procedures.

To ensure you properly apply a coat of epoxy to your garage floor, just follow these steps:

Remove existing coatings and residue.

Before you apply an epoxy coating to your garage floor, you first need to inspect the concrete. There cannot be any existing sealant or paint on your concrete. If there is, then you will need to remove it.


The reason it needs to be removed is because epoxy will not stick to a painted or sealed concrete surface. So, if any of these are present, you will need a mechanical grinder to remove them.

Next, you will want to inspect the concrete for other kinds of markings and residue, such as rubber markings from tires, oil stains, grease stains, cracks, holes and so on. You’ll want to remove the existing markings and stains with a degreasing solution.


You may even need to sand off the rubber markings because those are tougher. As for the cracks and holes, you can refill them with new concrete and wait 30 days for it to dry.

Etch the Garage Floor

Once your garage floor is completely clean and spotless, the next step is to apply an etch coating to it. The standard ingredient for most etching products is muriatic acid. You’ll need to scrub this solution on your garage floor using a scrub brush.


The purpose of etching is to open the concrete’s pores. This will enable the epoxy coating to stick to the concrete. If you fail to etch the floor, there will be numerous imperfections after the epoxy coating is applied.

There are etching kits that explain the application process. Basically, you presoak the floor, mix the muriatic acid with water and then apply the solution to the floor. You then rinse the floor and give it time to dry.  

Apply the Epoxy Coating

Now it is time to apply the epoxy coating. The primary ingredient is an epoxy resin, and it is sold in numerous sized containers, including 5 gallons, 1 gallon, and 1 quart.


Other ingredients you will need to purchase separately are the catalyst, pigment and texturing materials. The catalyst helps the resin harden after it is applied to the garage floor. The pigment gives the epoxy its unique colour.


Mix these ingredients together. Use a roller to apply this mixed solution to your floor.

Finish up.

Once the epoxy coating has been applied, it is time to clean up. However, you will need to throw away the roller cover because the resin is too dangerous to be merely cleaned off.


Throw away any other materials which were marked or stained by the resin. As for the floor, it will need time to dry and settle. If you want to apply texture materials or paint chips, you will need to insert them and apply additional epoxy coatings to help them settle.
