Garage floor epoxy is the industry standard for a tough, attractive garage floor surface. Despite the fact that “epoxy paint” is a common term, epoxy and paint are two different products with different chemical compositions. Epoxy is a more durable coating than paint, but it is more difficult to apply. The keys to success are meticulous preparation and a well-organized approach. Because the application of garage floor finishes varies a little from one product to the next, make sure to read the instructions for the one you choose.
Instructions and Preparation
- The floor should be cleaned and degreased.
To clean the floor, use a broom and a wet-dry vacuum. The grease can be removed using a degreaser and a stiff brush. Allow the floor to dry after rinsing the degreaser with a garden hose.
- Concrete should be etched.
Following the manufacturer’s instructions, etch the concrete floor with the etching solution included in the epoxy coating kit. Wear all of the necessary safety equipment. As indicated, mix the etching solution with water.
- Make the Room Ready
Tape the bottoms of the walls using wide painter’s tape. Plastic sheeting may also be taped to the lowest foot or two of the walls. Consider removing baseboards if it’s not too tough, as this will allow you to apply the epoxy directly to the wall, eliminating the need to cut in the edges with a brush.
- Epoxy should be mixed together.
Two-part epoxy is made up of a catalyst (or hardener) and a resin (or “paint”) that must be mixed together immediately before use. Swirl the paint for a few seconds before pouring in the catalyst and continuing to stir. After the catalyst container has been emptied, stir for a few minutes to thoroughly combine the two components.
- Epoxy should be used.
As soon as the epoxy mix is ready, begin applying the coating. Applying the epoxy will take no more than two hours, and in hot conditions, even less time. During the application and initial cure, keep the garage properly ventilated. Cut in along the edges with a 3-inch paintbrush, then lay epoxy over the floor with a 9-inch roller with a 1/2-inch-nap roller cover. Work in ten-by-ten-foot pieces.
- Allow the garage floor to air dry.
Wait at least 24 hours before walking on the new epoxy surface, and at least a few more days (ideally a week) before pulling the car back into the garage.
