Most manufacturers and contractors recommend sealing pavers for a reason. The materials from which paving stones are made, such as concrete and stone, are porous, meaning they absorb liquids and can become stained. Sealing pavers is the most beneficial thing you can do to ensure they last longer, prevent stains, and maintain their beauty. Without sealing, pavers can suffer from erosion, weed growth, mold or mildew accumulation, discoloration, and may come loose.
Paving stone sealer is an important maintenance tool for keeping patios, walkways, driveways, and paving stone decks looking as beautiful as when they were first installed. While most paving stone manufacturers will tell you that sealing isn't necessary, it's highly recommended. 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 quickly. Additionally, sealing helps protect the color pigments in pavers from fading due to exposure to UV rays.
Sealing your pavers is not a difficult task but it does require some experience. If done incorrectly, it can cause more harm than good. Before sealing your pavers, it's important to clean them thoroughly to remove any dirt or debris that may be present. This will not only clean the surface of the paving stones but also clean the pores of the paving stone, allowing better penetration of the sealant.
Once the pavers are restored and cleaned, they must be sealed to protect your investment and maintain their beauty. Sealing your pavers is a great way to protect them from erosion, weed growth, mold or mildew accumulation, discoloration, and coming loose. Additionally, it helps keep the color pigments in pavers from fading due to exposure to UV rays. While sealing isn't a difficult task, it does require some experience and if done incorrectly can cause more harm than good.
Cleaning your pavers before sealing is essential for ensuring that the sealant penetrates properly and provides maximum protection.
