A paver sealer is a product designed to provide a protective layer to your patio pavers. It is especially beneficial if your patio is frequently exposed to harsh weather conditions or heavy foot traffic. The sealer prevents water absorption, inhibits weed growth, and helps maintain the original color of the pavers. Applying a sealer soon after your pavers are installed and resealing every one to two years is a good practice to extend the lifespan and maintain the aesthetics of your patio.
