Does Paver Sealer Harden Sand?

A paver sealer is a protective coating that’s applied to the surface of pavers to enhance their appearance and longevity. However, if left untreated, the sand can easily wash away or erode due to weather conditions or foot traffic. This is where the paver sealer comes in. It not only enhances the color and overall aesthetic of the pavers, but it also acts as a barrier, locking in the joint sand and preventing it from being washed away or eroded.

Does Sealing Pavers Keep the Sand In?

In addition, sealing pavers helps to keep the sand in place. When pavers are installed, joint sand is swept in between the cracks to provide stability and prevent shifting. Over time, however, wind, rain, and foot traffic can cause the sand to dislodge, leading to gaps and uneven surfaces. By applying a paver sealer, the sand is effectively locked in place, ensuring a more durable and long-lasting pavement.

Furthermore, sealing pavers helps to prevent weed growth. Unsealed pavers provide an ideal environment for weeds to take root and grow between the cracks. These unwanted plants can be unsightly and difficult to remove.

Moreover, a paver sealer helps to prevent staining and water damage. Unsealed pavers are more susceptible to absorbing spills and stains, such as oil, grease, or chemicals. These stains can be difficult to remove and may mar the appearance of your pavement.
