How Often Should You Seal Pavers?

Test for Resealing

• If your paver surface is a few years old, a basic test will tell if it is time for resealing. One of the simplest ways is to spray it with a hose and then look closely at the surface. Sealing repels moisture so you should see water beading. If it doesn't bead, it's time to apply a new coat.

Re-sanding

• In addition to protecting pavers, sealant also preserves the fine sand packed into the joints. Sand joints are essential in keeping the pavers from shifting. Before resealing, look at the sand levels between stones. Use a shop broom to work fine sand into the narrow crevices. Moisten the surface to weigh the sand down and add another layer until the joints are packed.

Application

• Resealing a paver surface is a two-part project that involves treating the surface to remove any stains and debris and applying the sealer. Use a stain removing solvent and scrub brush to remove as much dirt and grease as possible. Once the solutions are rinsed off and the surface is dry, you can roll the new sealant on in two thin coats.

Benefits

• Maintaining a protective coat of sealant increases the longevity of your surface. Acrylic, urethane and other outdoor sealants form a barrier so water cannot penetrate the surface. In addition to preventing weeds, stains and other eye sores, sealant improves appearance by adding a clear gloss or matte finish.
