Washed stone paving

Main methods for water-washed stone paving:

1. Clean the Substrate: Thoroughly clean the surface of the substrate of accumulated dust, grease, loose mortar, and debris. If there are uneven areas, level out the protrusions and fill in the depressions with 1:3 mortar. For oil stains, use a 10% lye solution to scrub clean, then rinse with water and dry.

2. Apply Base Mortar: First, apply a plain cement slurry (mixed with 10% of 107 adhesive water) to the base layer. Then, apply the base mortar in layers. Use a straight edge to level the base mortar and a wooden trowel to roughen it. After the mortar has set, water it for maintenance.

3. Gravel Mortar Surface Layer: Apply a coat of plain cement mortar, then apply two layers of gravel mortar from bottom to top. The surface should be 1mm higher than the completed ground on both sides. Flatten and compact the gravel mortar layer.

4. Use a brush dipped in water to remove the surface cement paste, then recompact and smooth it. Repeat the brushing and pressing process 3 to 4 times. Once the surface starts to set, when water brushing no longer removes the stone particles, one person should brush the cement paste with a damp brush, while another sprays water from a hose 20 cm above the ground. After the surface is cleaned and the stones are exposed, rinse the surface clean with clear water and seal it. Assign a person to water the surface for maintenance. If cement paste residue is found on the stone surface after maintenance, use oxalic acid to scrub it off. Note that the residual oxalic acid solution must be diluted and drained into the storm drain, not into the green areas.
