Epoxy dries thick and hard, both waterproofing and providing a durable finish. Epoxies are also an excellent solution for a high-traffic basement, such as one that is used as a recreation area or workshop. There are three types of epoxy: water-based, solvent-based and 100 percent solid. They come in a range of colors, including green, ivory, brown and red.

If you plan on placing carpet, hardwood or another flooring material on top of a concrete basement floor, consider applying a few coats of epoxy to the concrete before laying the floor. This will work as a moisture barrier and prevent future water damage.

Be sure to apply the epoxy to a cool basement floor, which will help it to adhere to the surface. Use a long-handled roller to apply the epoxy in a thin coat. A second coat may be necessary, but be sure to allow 24 hours before applying it. Wait until the epoxy has fully dried before installing a new floor.
