Pre-wet the surface. Open bucket, cut open vacuum-sealed plactic bag and spread material evenly over the surface. Carefully brush into the joints with a street broom (or a rubber broom).
Rinse the area with a gentle stream of water to compress the material into the joints. Do not direct a strong jet of water directly into the joints. Once the water flow is stopped, the curing process begins.
Grout residues on the surface can be removed by carefully brushing diagonally across the joints with a soft to medium broom. A gentle jet of water helps finishing the cleaning process.
Note: Do not sweep residual material into open joints.
