Step 3: Spread the Resurfacer

Fill the walkway joints with peel-and-stick foam weatherstripping, and dampen the concrete if necessary. The resurfacer is workable for about 20 minutes, so mix just half a bag of powder with 5½ cups of water at a time. That's enough to cover two sidewalk slabs, or about 17 square feet. Pour it on the walk.
