How to Fix Poly Sand Haze

To understand what poly sand haze is, let’s first take a look at how pavers are installed. Most pavers, regardless of whether it is a driveway, sidewalk, patio, or pool deck area, are laid on a compacted bed of sand. The bricks are laid out in whatever pattern you desire and are leveled to create an entire paver structure. Sand is then poured onto the paver surface and swept into the gaps between the pavers. This is typically fine polymeric sand especially designed for paver construction.

The polymeric sand joints are then misted with water. The water reacts with the poly sand and creates a binding agent that helps bind the sand particles together. However, before water is misted onto the surface, the poly sand dust leftover on the surface must be completely removed. If the poly sand dust is not removed, it will create a white haze on top of the pavers. This is called poly sand haze.
