Transparent waterproofing without formed membranes (wall tiles or sponge-washed exposed aggregate surfaces)

1. Remove or wash off all objects, dust, and loose material from tiled or pebbledashed (sponge-washed exposed aggregate concrete) external walls and allow a drying time of at least three days.
2. Fine cracks on construction surfaces should be filled with neutral transparent silicone sealant. For deeper dents or cracks, rapid-hardening water-plugging powder may be utilized. Wait until the construction surface is completely dry.
3. Apply 2-3 coats of nano-level ultra-permeable crystalline waterproofing agent at intervals of at least 30 minutes. Wait until completely dry before applying the next layer.
   Optimal impermeability effects are achieved after2-3 days.
