Finish by lightly dampening the sand with water by misting with a garden sprayer to allow the sand to settle. If you use the filling material for coloured, porous pavings, it may settle in small depressions in the stones, leading to discolouring. This can often be removed with a brush and some soap – see how in our cleaning guidelines.To avoid weeds and displacements in the coating, the joint must always be filled to the full height of the joint edge and be completely free of soil and other organic material. The coating is cleaned with a stiff broom and the joints are refilled as needed. Moss and algae can be removed by suitable means. Extreme weather conditions can cause white blooms in the joints and on the edges of the paving stones. However, they are usually washed off at the next rain shower. The salt deposits can also be removed by regular cleaning of the stones.
