DO a thorough job cleaning...
The steps, because concrete has to be pristine and moisture-free for paint to adhere. Scrub with a nylon bristle brush and a degreaser. Let dry at least 48 to 72 hours (check the label for drying times).
DON’T underestimate...
How porous concrete is. It’ll soak up paint like a sponge, so use masonry or concrete primer and paint. Apply with a synthetic roller that has a 1-inch nap. The long fibers grab lots of primer and paint, and they’ll help speed up the job.
DO remember that painted...
Concrete is slick when it gets wet. One way to decrease the risk of slips is by mixing an additive like Behr Premium nonskid floor finish additive into the paint. It gives stairs the grittiness of sandpaper, and usually the texture isn’t visible.
