Paver sealer is an important component of maintaining the integrity and appearance of pavers. Pavers are porous and can absorb moisture and stains, which can lead to discoloration, mold growth, and damage over time. A paver sealer helps to protect against these issues by creating a barrier between the pavers and the elements, preventing water from penetrating the surface and resisting stains. Additionally, a quality paver sealer can enhance the color and vibrancy of the pavers, adding to their aesthetic appeal and increasing their longevity.
