Construction method for spraying polyurea waterproof coating on roof
The invention discloses a construction method for spraying a polyurea waterproof coating on a roof. The construction method comprises the following steps: treating a base layer, accepting the base layer, constructing a primer, protecting a non-waterproof area, constructing a strengthening layer, spraying a polyurea waterproof layer, repairing a coating and protecting a finished product. The construction method is convenient to use; the finished waterproof layer obtained after construction is an integral elastic layer, high in tensile strength, corrosion-resistant, high in elasticity and aging-resistant, is completely adhered to the base layer firmly through full adhesion, and is tight in edge sealing, free of overlapping risks, seam risks and other leakage risks and good in waterproof effect; even if local damage, the waterproof layer can still avoid water accumulation and fluid channeling, so that the erosion of a harmful medium on concrete is completely eliminated; the waterproof layer can maintain flexibility at a low temperature, so that the performance of the waterproof layer is not affected in a frozen environment; the waterproof layer is high in curing and film-forming speed, high in construction efficiency and construction speed; the construction quality of the waterproof layer can be ensured; complex node treatment is simple.
