How long before it can rain on polymeric sand?

Most poly sands are considered “rain proof” after one hour, but I wouldn’t bet the bank on that. You really want at least 24 hours of warm, dry air to ensure that the poly sand completely sets. Sustained dampness prior to setting may damage the poly sand to the point it will never set.

How big a gap can polymeric sand fill?

How Big a Gap Can Polymeric Sand Fill? Polymeric sand works best to fill gaps between 1/4 inch and 1.5 inches wide. Wider joints will require more time to harden. Some pavers are designed to fit together like puzzle pieces – if the gap is too small, polymeric sand won’t help.

When should you not use polymeric sand?

#6 – Too Narrow or Too Wide Joints

The sand is simply pushed out of the joints. This is why we don’t recommend using polymeric sand on extremely narrow joints. Similarly, too-wide joints can lead to washout, because they allow too much water flow during the activation process.

Will polymeric sand stop pavers from moving?

Polymeric sand helps to hold the pavers in place and prevents them from shifting or moving.
