Quartz sand is used in conjunction with AquaSell to create a strong surface for microcement with a good key.
Whilst the AquaSell is still wet, spread the quartz sand across the surface. You can scatter it by hand, starting at the entrance to the room and walking on the sand into the room. Or by walking on the AquaSell with spiked shoes.
For larger areas, you may need a 2nd person spreading the sand as the 1st person trowels on the Aquasell.
Leave to dry. Minimum of 12 hours. Ideally overnight.#
