Description

Repairing method of waterproof coating
Technical Field
The invention belongs to the technical field of waterproof repair, and particularly relates to a repair method of a waterproof coating.

With the improvement of economic level, people put higher requirements on building quality and water and leakage prevention of building engineering.
The spraying rapid-hardening rubber asphalt waterproof coating belongs to a water emulsion type material, mechanical construction spraying, green safety and environmental protection, and high construction efficiency, but the spraying rapid-hardening rubber asphalt waterproof coating belongs to a two-component product, which is divided into two components of A and B, wherein the two components are atomized from a spray gun according to a certain proportion during spraying, then sprayed out, contacted with each other in the air and rapidly solidified into small particles, then piled into a certain shape and thickness, and finally water is analyzed out. The strength of the sprayed film is increased along with the analysis of water until the water is completely separated out and the quality of the sprayed film reaches the optimal state. In the spraying process, the defects of incomplete spraying film, cracks, gaps and the like are often caused under the influence of a spraying construction method, and the problems of crushing, puncturing and the like sometimes caused by the influence of external force after the spraying film is cured are solved.
The above defects are not revealed until the sprayed film is cured. The traditional repairing mode is to reuse a spraying machine, spray the rapid hardening rubber asphalt waterproof paint and then carry out spraying construction, so that the defects are sprayed and covered again, and the spraying film to be repaired can play a repairing role after being cured. The repairing method needs to drag the machine, the coating and the curing agent to a specified position for repairing, and has the problems of difficult construction, time consumption and labor consumption when the construction area is large, the number of defect leakage points is large, and the defect position is special (such as a high-position vertical wall, a small construction surface in a pipeline and the like).
In addition, if the spraying repair method is not adopted, the asphalt sealant or the asphalt coating material is directly used for coating and covering, and the repair method has low adhesion due to low strength and insufficient viscosity of the sealant and the asphalt coating material, so that water in the base layer can seep out from the leaking stoppage defect, and water seepage and water leakage are caused.
