Sealing your patio pavers effectively is essential to their lifespan and appearance. Most importantly, clean them thoroughly before beginning the sealing process — any dirt, plant matter, or other debris will interfere with the sealer’s ability to properly adhere to the stones, creating an uneven finish and reducing its durability. A deep spray from a power washer is the best method, but a hose down and a good sweeping with a thick-bristled broom should also suffice.
While wearing protective gloves and eyewear, apply the sealant in even layers across the pavers with a sprayer or roller. Allow the sealant to dry before applying a second layer. The second layer is crucial to fortifying the protective barrier, though it is important to apply the sealant in thin coats. Be sure to cover the entire surface and remove any excess — pay close attention to the joints between the pavers as the sealant can pool in these crevices.
Always follow the drying instructions on the manufacturer’s label for the sealant. Although some sealers claim they are quick-drying, it’s best to wait twenty-four hours before walking on the patio or laying out your furniture. The weather will also determine how quickly the patio pavers cure, so choose a warm dry day, and take extra caution if you live in a humid climate.
