Can Gap Sand be used around Swimming Pools?

Due to the splashing of water in a pool area it is not advisable to use Gap Sand to lock pavers into place within 1 metre of the pool edge. It is better to use Sand & Cement to fill the gaps between these pavers.

What product is recommended for filling gaps in paving greater than 3mm?

Ensure that the pavers are dry and sweep the Sand & Cement into the joints and tamp it down into the joints.

Remove any excess sand with a dry brush and then wet the paved area with a light mist spray. Ensure that pools of water do not form on the surface or the Sand & Cement will be dislodged from the gaps and your pavers will not be held firmly in position.
