How To Seal Pavers With Sand. After investing in a new paver patio or driveway we recommend joint stabilizing silica sand and sealer, which is a combination of using joint stabilizing silica sand and a liquid product that. When that sand goes away, there are little spaces between each paver allowing them to move around because they’re no longer tight.
This will cause the sand to consolidate. Here is an image of pavers treated using polymeric sand: Over time, that sand is blown away by the constant exposition to the wind and the rain, and has to be refilled.
Polymeric sand is a special type of sand that is placed between the cracks of the pavers.
The pavers on the left are sealed using an enhanced joint stabilizing sealer. When combined with water the sand and polymers mix creating a strong bond and locking the pavers in place. Sealants fill the pores and repel water by preserving the sand dust in the joints. Pour the sand onto the pavers and sweep it into the joints.
