That dingy concrete slab will look even more drab once you've tidied up. An antiskid floor coating resists oil stains and wipes clean as easily as a kitchen countertop does—plus the color chips and paint disguise any imperfections. Pick up an all-inclusive kit (such as Quikrete's Garage Floor Epoxy Kit, about $60; amazon.com), and plan to tackle the project when you'll have a few days of temperate, 50- to 80-degree weather for adequate drying time. The key to success is diligent prep work—namely a clean, dry slab.
