Sealing pavers is one of the most effective ways to ensure their longevity, prevent staining, and maintain their beauty. Without sealing, pavers can be subject to erosion, weed growth, mold or mildew accumulation, discoloration, and even loosening. When it comes to choosing a sealant, there are two types of products available: solvent-based and water-based. Before applying a paving stone sealer, it is important to make sure the pavers have been thoroughly cleaned.
Sealing can also protect pavers from any foreign substances that may fall on them, such as oil stains, leaves, or spills. Pavers are exposed to the same elements as an entryway, deck, porch, and patio, so while sealing is an optional maintenance step, it makes it easier to clean. Sealing creates an invisible layer on the top of the pavers that repels water, oil, and anything else you might accidentally drop - as long as you wash it off immediately. Not only will this clean the surface of the paving stones but it will also clean the pores of the paving stone, allowing for better penetration of the sealant.
It will not alter the color of the paving stone but will instead highlight its tone and improve its color. Whether you have a brand new patio made of paving stones or a beautiful walkway or driveway made with pavers, you may be wondering if you need to add a sealer. In addition to protecting pavers from absorbing stains, sealing pavers has other benefits as well as some disadvantages. If you seal the cobblestone too soon, you'll save those salts and minerals instead of allowing them to bleed out the way they want. Even if your patio is already installed, you can find a paving stone installation company in your area that can apply paving stone sealer for you.
Most paving stone manufacturers will tell you that sealing is not necessary but highly recommended.
