Waterproof coating: According to different building parts "instruction according to their aptitude"

Different construction sites require different waterproof materials. Each kind of material has its own strengths and weaknesses. A material cannot be packaged in the world. Materials used everywhere are not. Materials can only be complementary and cannot be replaced. They are each useful. Roof waterproofing and waterproofing in the basement require different materials, and the waterproofing between the bath and the wall is more different. The sloping roof, the complicated roof, and the metal roofing roof are also different. When selecting materials, consider carefully.

(1) The roof waterproofing layer is exposed to nature, exposed to hot sunlight, wind blows, and rain and snow erosion

The temperature of severe cold and winter heat afflicted, the change of temperature difference between day and night was repeated, and there was no excellent wood quality and good protection measures. It was difficult to achieve the required durability. Therefore, a waterproof material with high tensile strength, high elongation, and good aging resistance should be selected.

(2) Why the wall leaks, because now the wall is too thin, mostly for light block masonry, a large number of internal and external joints, and then the combination of doors and windows and the wall, the seal is not strict, rain from the seam infiltration. Waterproof wall can not be used coil, only paint, and the combination of exterior decoration materials. Only sealant can solve the problem.

(3) Waterproof materials for underground buildings. The underground waterproof layer is soaked in water or very moist soil for a long time. The waterproof material must have good water resistance.

(4) There are three characteristics of waterproofing in toilets. The first is not affected by the natural climate, the temperature change is not, the material's elongation rate is not high; second, the area is small, there are many yin and yang angles, and there are many pipes through the floor; Third, the waterproof layer on the wall is tiled and bonded. Agent affinity is good. According to the above three characteristics, it is not possible to choose a coil, only the coating is most suitable.

(5) There are more and more overpass projects in urban construction, and reinforced concrete slabs must be waterproof in order to extend the service life.
