Treatment of glass fiber cloth wall insulation base

Thoroughly remove the floating ash, oil stains and other substances that affect the construction of the wall on the surface of the base wall. Flatten or repair the convex and concave parts of the wall. Block the holes in the wall, clean the holes with a wire brush, or block the holes with rubber powder polystyrene particles. All base-level walls should be fully coated with base-level interface mortar.
