Waterproof Coating For Interior Basement Walls

Waterproof coating for interior basement walls      Base surface treatment is the key to waterproof coating basement construction. The base surface must be cleaned before construction to ensure that it is firm, waterproof coating for interior basement walls, flat and clean, free from dust, greasy, wax, mold release agents and other debris, such as defects such as voids and cracks. It must be repaired and smoothed with cement mortar in advance, and the yin and yang corners should be smeared in a circular arc shape.
