Concrete sealers will help your garage floors resist water, but they will not make the floor waterproof. You will need to purchase a specific waterproof floor paint for concrete and apply several coats over several days if you want your garage floor to be truly impermeable. While the process is similar to sealing the floors, the materials are different, and the need for multiple coats will extend the process and drying time.

Yes, it is possible to apply a concrete coating yourself, especially for smaller applications if you have the proper equipment. However, for larger projects, a professional application is recommended to ensure durability, slip resistance, and proper adhesion.

The cost for concrete coating services ranges from $3 to $15 per square foot. The final price is contingent on several factors, including the extent of surface preparation needed, the type of coating used, the total area being covered, and labor.

Epoxy tends to be the most durable concrete finish, holding up on garage and shop floors for years. Epoxy seals the slab's surface, will run into any cracks and crevices, and can help to level the surface, so it tends to be a durable finish for most applications. The downside to epoxy is that it can be difficult to remove once applied.
