What should do if th steel structure building workshop roof is rotten?
There will be rotten asphalt on the roof of the industrial factory building of steel structure engineering, so it is necessary to use shovel to remove them one by one. In particular, once the small screws are not removed, the waterproof coating will be applied, and water seepage will occur after a period of time. The small screws will make the roof void rot. After removal, the sealing gasket of small screws shall also be knocked tightly to the roof surface of the steel structure building workshop.
Solve the previous step, and then carry out the preparation before painting. Mix the paint first, but do not add water or auxiliary materials. It's good to have a blender. It's OK not to have an iron bar. Then cut the polyester cloth according to the size of the convex and concave part of the roof. It is generally about ten centimeters. Cut according to the specific situation. In addition, necessary measures for labor protection shall be taken.
Once the preparations are well done, you can come out and paint
First coating: paint a layer of base waterproof coating on the clean and intact datum plane. Use the method of painting, not roller painting or brush painting. Because painting can make up the coating to every gap, and thus more reasonable waterproof. Rolling and brushing are very restrictive.
One cloth: When the first coat of paint is not dry, quickly pave a part of the projection of the roof with the cut polyester cloth.
Second coating: then apply a layer of base waterproof coating on the surface of the raised polyester cloth to make the coating sufficiently moisten and improve the polyester cloth to ensure that there is no bulge or wrinkle, so that the coating can be fully combined with the bottom layer of the coating according to the gap of the raised polyester cloth to form a seamless splicing overall, so as to solidify.
Third coating: apply a UV resistant surface waterproof coating on the surface of the solidified coating layer, so as to solidify.
FAQ: If the paint accidentally enters the eye, clean it several times with cold water.
