Epoxy Coating a Garage Floor

You finally got the tools hanging neatly on an outlined pegboard, and all the paint is organized in carefully labeled cabinets. But now your car is jealous, sitting like a lump on the oily, dirty concrete slab. You still need to put the finishing touch on the garage cleanup: a colorful, shiny epoxy floor coating that will have you—and your car—feeling like you’re driving into a showroom every time you come home.

Epoxy not only tops off the pro look but also resists oil stains, beads water, and wipes clean like a kitchen counter. Color chips and custom paint colors hide annoying imperfections in the concrete, and antiskid additives give you the grip you need on a snowy day. As This Old House technical editor Mark Powers shows on the following pages, you just need a weekend to sweep the dirt out and paint the epoxy on. Then the garage will finally be a space worth driving up to—and showing off.
