Sealer is considered a low maintenance product. Almost all damage to concrete is attributable to moisture intrusion. Sealers help protect concrete by blocking the pores in the concrete to reduce absorption of water and salts by forming an impermeable layer which prevents anything from passing thru it. We recommend resealing every 1 – 2 years but each individual project is different. Of course, high traffic areas such as driveways and parking lots will need to be maintained more regularly than a small patio with occasional use.
Never apply a sealer if you are unsure of the product. We have seen many people use inferior products to reseal and have great difficulty rectifying the damage. We can add non-skid additives that are directly mixed into the sealer or broadcast skid resistant materials across the concrete surface just prior to sealing.
