What kind of paint and sealer should I use on concrete flooring?
—Reyna, Port Arthur, Texas
You can use an acrylic-based concrete sealer to treat the slab in the basement, then top-coat it with a commercial grade acrylic paint specially formulated for floors. Check with your local paint store and tell them you want the best product for the job. Skimp on price and you'll only wind up making more work for yourself in the future.
