Clean the joint to a depth corresponding to the entire height of the stone. This is done using a joint cleaner. You can also use a high-pressure cleaner, but be careful not to damage the paving stones or the sublayer. Top up the joint. Finish by lightly dampening the sand with water by misting with a garden sprayer to allow the sand to settle. 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.
