Do Tumbled Pavers Get Sealed?

Seal of Approval

• Sealer provides protection against moisture from rain, ice, snow, pool water and other liquids. It also helps prevent sand loss in the joints and the bedding and keeps weeds and grass from growing up through the cracks. Sealer repels stains from grease, grime and food material and makes it easier to keep the surface clean, especially in indoor applications. It also enhances the natural colors of the paver material and lengthens the lifespan of the paved area.

Positively Glowing

• Paver sealer serves two basic purposes: protection and enhancement. A penetrable sealer forms a chemical bond with the pavers and sand, creating a moisture-resistant barrier that protects the stone, sand joint filling and the sand bedding beneath the pavers. A film-forming sealer adds a protective surface barrier that also gives a decorative finish, varying in intensity from a low sheen to a glossy, wet-looking shine.

Wax On, Wax Off

• The type of tool you use to apply sealer depends on the size of the paved area. For smaller sites, a paintbrush or paint roller does the trick. Use a garden sprayer to cover large areas such as patios or driveways. You’ll also need a squeegee to spread the sealer into the joints. Dalton Enterprises recommends using a wallpaper brush or a clean, new broom to apply sealer to edges. Use plastic paint tarps or old newspaper and tape to protect surrounding areas or objects from overspray. Wear protective clothing, including safety glasses and a dust mask, to avoid breathing in fumes or getting sealer in your eyes or on your skin.

Sealing the Deal

• The paved area must be completely clean and dry before sealer is applied. Most brand new pavers need to cure for at least two weeks before applying sealer. Check with your contractor or the paver manufacturer to determine how long you need to wait. Move all patio furniture, planting containers and other moveable objects away from the area and spray it down with water to remove any dirt and debris. Depending on the paver material, heavy-duty paver cleaners or acidic cleaners can be used to remove existing grease, grime or efflorescence. Thoro recommends spraying the area with a solution of 1 quart bleach mixed with 5 gallons of water to remove any algae, mildew or mold from the surface. Sealer can be applied once the entire area is thoroughly cleaned and allowed to dry for at least 48 hours.
