To adhere well, epoxy requires a uniform, slightly rough and totally clean surface. That means repairing potholes and cracks and letting them dry completely. The concrete must be at least 60 days old and not sealed for the epoxy to adhere. You can tell if your floor already has a sealant, if there are drops of water or if the etching solution doesn't foam; if that's the case, you'll have to remove the sealant with a chemical stripper or with a special machine.
Painted floors can be coated if they are not peeled. That way, your garage floor will get an even distribution of color scales from one section to the next. The best way to do this is to close the garage door a few inches from the floor once done. Many of the videos you can watch online that show the epoxy application process don't use 100% solid epoxy.
The second layer will be the colored layer or the top layer, depending on the epoxy floor coating system you are installing. Most epoxy paint coatings can be applied at temperatures of 55 to 90 degrees, and temperatures between 70 and 80 degrees are considered ideal. Unless you use a water-based epoxy primer that allows it to be applied to wet floors, you'll have to wait a minimum of 24 to 48 hours for the soil to dry completely, sometimes longer if the climate is more humid. Since it's the first layer and you don't know how much epoxy the concrete will initially absorb, it's best to start rolling first to get 200 square foot coverage.
The next step is to inspect the garage floor for any visible signs of moisture and perform a moisture test if necessary. It's worth putting epoxy on the garage floor, since epoxy not only completes the professional look, but it also resists oil stains, water droplets and can be cleaned with a cloth like a kitchen countertop. Any remaining epoxy left on the floor can be picked up with a wide spatula, a drywall spatula or an old dustpan and placed in the mixing bucket for disposal. In reality, you only need blasting if you are looking to strongly profile the concrete to obtain a thick layer or if a super thick layer currently exists.
If the garage floor is much wider than it is deep, for example, work from side to side rather than front to back. But what is it? And how can you ensure that you're getting high-quality epoxy floors? There are many garage floor coating companies that offer “the best epoxy floors” and “1-day polyurea-polyaspartic coating systems”. Moisten the entire floor with a hose and then scrub it from side to side with an electric scouring pad with a brush (or a thick scouring pad if no accessory is available). Add an anti-slip product to the epoxy to apply the second coat, especially if your vehicles drag snow and moisture into the garage, or you would feel safer on a less slippery floor.
