If you have an epoxy garage floor, you may wonder how to touch up small damages and fix dents in the finish. You may be considering a DIY project, but you will need several tools, including a sandblaster and an air compressor. Fortunately, there are some steps you can take to avoid the cost and hassle of hiring a professional. Before you start, be sure to clean up any debris or dirt on the floor.
Repairing small damaged areas on epoxy garage floor
If you’ve noticed a small crack in your epoxy garage floor, don’t despair. It’s not as hard as you think. All you need is a sandblaster, air compressor, and two-part epoxy. Repairing a small area on the floor can take less than an hour. Before you begin, remove any lawn mowers or other items that are stacked on shelves. Ensure that the area is dry before proceeding.
While concrete epoxy garage floors are a durable, low-maintenance flooring option, damage can occur over time. Excessive weight on the floor, continuous use, and even weather can cause damage. Whether it’s a minor chip or a large crack, a small chip on an epoxy floor can present a safety hazard. Fortunately, small repairs are easy and inexpensive, so they’re well worth attempting.
Preparing concrete for epoxy garage floor
If you want to apply an epoxy garage floor coating to your garage, you must prepare the concrete surface to allow the coating to adhere properly. One way to do this is to use an acid etching agent to clean the surface. This will help open the pores of the concrete, allowing the epoxy to bond with it. If the concrete surface is clean and dry, it may not be necessary to use an acid etching agent.
Once you’ve cleaned the concrete surface, you can begin the preparation process for the epoxy coating. The kit you purchase will contain a chemical etching solution to open the pores of the concrete slab. Mix the etching solution with water and work it in with a stiff brush. The solution will bubble and fizz and abrade the surface of the concrete slab. You’ll need to wait several days for the concrete to dry completely before continuing with the application.
Using scuff sand paper
If you notice spots or other imperfections on your epoxy garage floor, it may be time to use a scuff sand paper to finish it. If you have an epoxy garage floor, you have about two hours before it starts to dry out. If the surface is damp or too hot, the coating could peel or bubble. The first step is to apply a small amount of the paint to the affected area. Make sure to start your work in a back corner of the garage to ensure even coverage.
Afterwards, apply a fine-grit sandpaper. The sand paper will help to smooth the area, but make sure you use a scuff-free surface. You can also use furniture polish on the surface to restore the sheen of the coating and blend it with the surrounding area. Once it is ready, touch up the scratch by painting it with another coat.
Using polyurea as hardener
If you’ve ever thought of using polyurea as a hardener for your epoxy garage floor, you’re not alone. This material has the highest solids percentage, which means that it’s best for hiding blemishes and preventing hot tires from lifting it while driving. It also has a faster cure time than epoxy and is several times more durable. To prevent a bubble-prone finish, make sure you apply polyurea as a hardener after applying the epoxy.
Unlike traditional paints and coatings, polyurea provides a smooth, appealing surface that is highly resistant to oil, grease, and chemicals. You’ll find that it’s also resistant to extreme heat and tire marks. It comes in different colors, including a blend of flakes and a variety of different textures. Depending on the look you want, you can opt for a color-matching touch-up that matches the rest of the room.
