The imprinted concrete driveway or patio should be completely dry. After pressure washing leave for 2-3 days for the concrete to dry out. Once dry, sweep the surface of the concrete to remove any dust, dirt or other contaminants. Apply the imprinted concrete sealer with a soft broom. Apply the 1st coat and then leave to dry for 1-2 hours depending on ambient temperature. Once dry or tacky to touch, apply a 2nd coat for long lasting protection to the concrete. Avoid applying the imprinted concrete sealer in direct sunlight or temperatures above 25 degrees centigrade. Do not apply if rain is forecast within 3 hours of application. We do not recommend putting de-icing salts directly on Smartseal block paving or concrete sealers. Salt chemically reduces the temperature at which water freezes and may result in water penetration into the concrete. Any subsequent freezing could result in the ‘seal’ being broken by the expansion of water once it freezes.
