Paver sealer can be used to coat the surface of pavers, preventing them from being damaged by water and other elements. Furthermore, there is a high possibility that the sand will leave the gap between each paver if left without a seal, littering the environment. But paver sealer keeps them fixed in between pavers.

When paver sealer is applied on pavers, it hardens and stabilizes the sand, making your pavers last longer. Erosion can also be prevented if the sand is stabilized. One might think a paver sealer doesn't do much, but they determine how long your pavers last.

Polymeric Sand For Pavers

One major factor to consider before choosing the sand for your paver is its binding power. Polymeric sand is known to have good binding power and can make your pavers last long. It contains 85 to 90% quartz and crystalline silica.

When you wet polymeric sand, polymers are activated. These polymers harden different components that keep the pavers in place. Additionally, they prevent the growth of weed and insect infestation. If paver sealers are used on polymeric sand, you will have a durable paver.

Polymetric sand does not allow much water to move through, so the material beneath should be free draining. The first layer that plays the role of a leveler should be capable of draining water. If not, you can install your pavers on sloppy areas so water will be drained from the foundation.

Polymeric sand can be used in landscaping to substitute for gravel or pebbles. They can also be used as a concrete additive in construction and an alternative to traditional clay pipes.

Can Regular Sand Be Used Between Pavers?

All-purpose/leveling/paver sand can be used instead of polymetric sand. It is less expensive and can be easily worked on if there is a need for adjustment or replacements of each paver. The processes involved in sealing your pavers with all-purpose/leveling/paver sand and polymeric sand are similar.
