ROMPOX® - JOINTING SAND NP is ideal for narrow joints, especially for interlocking block paving, on patios and driveways with light vehicle loads.
Pour the jointing sand onto the dry surface and mix it with a spade, to ensure the best mixing of grainsize.
Using a broom work into the joints. In order to achieve the best filling of the joint, always sweep diagonally to the joint.
With new construction we recommend compacting using a vibratory plate as long as the paved stone / slab covering is suitable for vibratory plates.
If necessary, any sand residue left on the surface can be swept off using a large, coarse broom the next day. The surface is loadbearing after 24–48 hours.
Then wet the joints using a spray set to fine mist (Do not use a watering can). The joint should be moistened until it no longer absorbs the water. Repeat this process after 1-2 hours.
