Type of Sand Used to Put Over Driveway Pavers

Benefits of Polymeric Sand

• Manufactured to fill the spaces between pavers, polymeric paver sand contains polymers. It hardens to the pavers like concrete, while allowing them enough flexibility to move under pressure so they don't break. Unlike other types of landscaping sand, polymeric paver sand is dense and won't retain water. It also reduces overall maintenance by blocking weeds from growing and debris from building up between pavers.

Installation

• Installing polymeric sand is a straightforward process. Once all of the pavers are laid, sprinkle the sand over the driveway. Use a stiff broom to push it into the joints and pack it down. Once the excess is brushed off, lightly spray the entire driveway with water. Use just enough water to moisten the sand so it hardens to the pavers as it dries. Using too much water causes the sand to float away.

Sealing Sand Joints

• After the polymeric paver sand dries and hardens to pavers, the best way to preserve the sand joints and keep the pavers from fading is to seal the surface. Use a clear, penetrating paver sealant and apply it with a roller brush or paint brush.

Replenishment

• Harsh weather and the daily stress of vehicles eventually cause sealant and polymeric sand to wear away. Depending on your region and the amount of traffic the driveway is exposed to, the sand should be replenished every two to three years. Re-sealing the pavers after reapplying sand makes the sand joints last longer.
