For best results, you should apply two coats of epoxy resin for garage floors. Before applying the first coat, be sure to apply a primer to the floor first. For best results, most manufacturers recommend applying a minimum of two coats of epoxy to the garage floor. Allow each coat to dry for at least 12 hours, but no longer than 48 hours, before applying an additional coat.
You can apply two coats of epoxy to your garage floor, but you must wait for each coat to dry before applying the next one. You can also apply as many coats as you want, which will help create a thicker layer of epoxy. Do the same if you have a worn coating that adheres very well, but has some stains where the coating has worn down to concrete. If you have an old transparent layer that you want to renew, you will first have to use 80 to 100 grit sandpaper or a 60 to 80 grit sanding screen to remove a small layer of the coating.
If the coating is quite worn out and looks more concrete than epoxy, then you'll want to start from scratch by shredding the floor. Once you've applied the first layer of epoxy and waited for it to dry, you can start applying the second coat. If the existing epoxy floor coating is peeling off or showing other signs of delamination, then you don't want to apply it with epoxy. It's best to wait until the first coat has dried before applying another coat of epoxy, but if you're short on time and need more protection than one coat can provide, you can apply a second coat right away.
The second coat should be applied before the first one dries, but not immediately after applying the first. The key to applying a new layer is to mechanically roughten the surface of the previous layer to create enough bite for the epoxy to adhere to it. It's not a problem to apply two or three coats to the garage floor, but if you use a 100% solid epoxy system, it's recommended to wait at least 24 hours between coats. Colors tend to be shown through white and that is why it is usually required to apply a layer of white epoxy primer first, followed by a layer of white epoxy with a high solid content of solids, sometimes two.
Make sure you don't skimp on this step if you do it correctly, as this can help protect you against future cracks or chips in your garage floor. If your garage floor already has an epoxy layer, you can use new epoxy over it; however, if there are cracks in the existing layer, it is recommended to remove it first and start from scratch with new material. Sometimes it's as simple as when someone planned a multi-layer flooring system and waited too long between coats, leaving the epoxy to harden, before applying the next coat to obtain a chemical bond. Once all the necessary coats have been applied, wait at least three days before driving a vehicle or other heavy equipment on the floor.
Once you clean the floor with denatured alcohol, you're ready to apply a new layer of epoxy or floor covering of your choice. If you want to apply a new layer of epoxy over an existing layer, it's important that the existing epoxy layer is completely dry (and has been dry for at least two days).
