How To Epoxy A Garage Floor

Until recently, I always used paint to coat my garage floor, but it ultimately proved unfit for the purpose. 

I found that most of the paint had worn out even though I had applied it just a year ago, and the surface looked dull, with chipping and cracks in a few parts. So, I decided on trying out a different coating that would provide better protection. 

But I couldn’t figure out which type would be most suitable. On discussing the matter with my husband, he suggested using epoxy as it would be more damage-resistant. But he also advised me to conduct a bit of research into the details. 

And I followed suit without any delay, which led me to learn more about the benefits of epoxy coatings and the application procedure. Soon, I made up my mind to go with it and gathered all the tools and materials needed. Within a week, I was done, and my garage floor looked better than ever! 

Hi! I’m Stacy, and today I’ll be telling you how to epoxy a garage floor effortlessly. So, let’s get started, shall we? 

How To Epoxy A Garage Floor

Buying An Epoxy Floor Coating

You’ll commonly find epoxy coatings being sold in complete kits, including the etching solution, decorative coloring chips, and two-part epoxy. There is also an instructions booklet that advises you regarding the safe usage of the product you’re purchasing. I’ve even come across online links for the instructions in the case of some products. 

Here, let me caution you that the color choices are limited, with most coatings coming in a simple gray, an off-white, or a brown color. 

Preparation

Before starting the procedure, you should take some preparatory steps to ensure that the coating is perfect. Remember that epoxy coatings work the best on concrete floors that are smooth and aren’t affected by chipping, spalls, or cracks. Hence, some repair work is needed if you find such damage on the floor. 

As I mentioned earlier, my garage had suffered damage in quite a few areas. Hence, I had to conduct some patching and repair work on the floor using a concrete patching agent beforehand. And remember that the patched areas should be cured and fully dried before you apply the coating. 

Tools And Materials Needed

Tools

• Stiff brush
• Eye protection
• Broom
• 3-inch paint brush
• Wet-dry shop vacuum
• 9-inch long paint roller
• Work gloves
• Garden hose

Materials 

• Painter’s tape
• Concrete degreaser
• Plastic sheeting
• Epoxy coating kit 

The Procedure

Step 1: Cleaning And Degreasing The Room

First, you should clean all the debris accumulated on the floor thoroughly to ensure that the coat is uniform. Use a wet-dry vacuum and a broom for the purpose. After this is done, use a degreaser and a brush with stiff bristles to remove the grease. Now, rinse the floor using a hose and let it dry completely. 

Step 2: Etching The Concrete

Put on the gear for safety and mix the etching solution as instructed in the manual, coming with the epoxy coating kit. Then pour this solution over the floor and apply it uniformly with a broom or stiff brush. 

Note that at this point, the solution might fizz and foam. This had made me a little worried at first, but my husband assured me that the process is on the right track, as the solution abrades the surface this way. Once you finish this, rinse the area using a garden hose and allow the concrete to dry up, which might take a few days. 

Step 3: Prepare The Room

Now, the room has to be prepared for coating it with epoxy to make sure there’s no inconsistency or hazard during the process. Start by applying painter’s tape along the lower portion of the walls. 

An alternative is to tape plastic sheeting to the bottom. And if you can, consider removing the baseboards. I did this because it made applying the coating just next to the wall quite easy and ruled out the need to cut its edges using a brush. 

Step 4: Mixing The Epoxy

The two-part epoxy in the kit includes a catalyst or hardener and a resin or the paint, which have to be mixed before applying the coating. Firstly, stir the paint a little and then pour the catalyst into it. Once the container with the catalyst is empty, stir the mixture thoroughly for a few more minutes.

Now, cover the mixture and rest it for as long as the manufacturer has specified. Note that if you’re using decorative coloring chips, don’t add them to the mixture. 

Step 5: 

It’s now that you have to begin to apply the coating. Usually, you won’t have to wait for longer than two hours for this. Remember to keep the atmosphere in the garage well-ventilated throughout the process and the initial curing. 

You should use a 9-inch paint roller having a ½-inch nap cover to spread the mixture across the floor. It will be more convenient to divide the work into 10 x 10-foot sections. Also, be careful while applying the coating on the edges; it’s best to use a smaller brush for the purpose. 

Having a helper for coating the edges would make the job quicker. I was lucky as my elder daughter helped me out with this. After you’re done spreading the epoxy, apply the decorative coloring chips if you plan to use them for the procedure. Take a few chips and then toss them up and out onto the garage floor. 

Step 6: Letting The Floor Dry

You must not walk on the epoxy-coated surface for at least a day and wait for a few more days to pull the garage and other tools back in there.
