Spread the resurfacer until it's between 1/8 and ¼ inch thick. For a slip-resistant finish, wait 5 minutes, then sweep a nylon-bristle broom across it, 90 degrees to the foot traffic. Remove the weatherstripping after 20 minutes. Wait 6 hours before walking on it. Cover only if rain threatens in the meantime.
