Steps to Follow in Apply Epoxy To Garage Floor

These instructions are basic for epoxy garage floor coating application.

1. Clean and Degrease the Floor

Epoxy can cannot be applied to a dirty surface and will need a thorough cleaning first. Sweep all loose debris, dirt and dust with the broom and make sure to get any odd bumps and cracks in the floor. If necessary you can even use a scraper to scrape the loose debris. This step is important because during application or otherwise, air bubbles and unevenness can form under the epoxy and ruin the surface.

Next you will need a concrete degreaser to remove oil, grease and other chemicals that may be on the floor. Once clean, a degreaser can be applied and scrubbed into the concrete with a stiff brush. Let the chemical sit for a few moments then sweep up any residue left behind before it dries off entirely.

2. Etching your concrete

You can even go further by etching the concrete floor before application. This will help promote a smooth and finer cured epoxy on the garage floor. If you skip this step then there may be a higher chance of air bubbles forming underneath resulting in an less than ideal appearance for your new epoxy garage floor coating. 

For etching concrete simply mix water with an etching solution in a few buckets. Pour the diluted mixture all over your garage floor and use a stiff brush to work it into the concrete. Make sure you keep this substance wet for 30 minutes then rinse off the formation left behind with clean water. This solution can be repeated 2 to 3 times if necessary but make sure not to over etch the chemical into the concrete.

3. Preparing the Room

Now that the floor is clean and degreased you can start preparing the room for application. You will want to cover items or furniture with plastic sheeting if they are near the project area.

Use the painter’s tape and mask off the sides and corners of the garage so that epoxy does run over the edges of the flooring. 

4. Mixing the Epoxy

Now comes the interesting part of epoxy garage floor coating application. Mix the epoxy and hardener in a container or plastic liner according to the manufacturer’s instructions on how much will be needed for your specific garage floor. The chemicals should be well mixed, but be fast because it will soon begin to harden and set once the chemicals come into contact and you will only have a few hours before it begins to set.

Mixing should be done in a well-ventilated area with proper safety gear. Gloves, eye protection and a dust mask should be worn to prevent injury. When mixing, these chemicals should have a milky color to them and after it has been well mixed, the epoxy should become uniform in color.

5. Apply Epoxy

Once the chemical is mixed it will need to be applied onto your garage floor right away. Use the roller extension handle and paint brush to apply to your concrete floor evenly and thoroughly so there are no patches where bare concrete is exposed. While the epoxy is wet, you may also want throw some decorative color chips and flakes to make your garage floor stand out. 

6. Dry the Garage Floor

Now to let the epoxy garage floor coating curing process take place. This will go to completion in about 12-24 hours so it is best not to allow anyone or anything step on your newly applied garage flooring before then. Wait 24 hours for the chemical reaction to finish and clear your room of any fumes or residual epoxy chemicals with a cleaner like ammonia or acetone before you can allow traffic back into the area and be safe from harm again. 

Once dry, the very last thing to do is apply a clear coat to give the epoxy a nice glossy finish. This can be done with a roller to get the job done evenly across the garage floor and let dry for a couple of hours as per manufacturers instruction.
