Light steel construction surface treatment

The roof structure of engineering building as the top load of the building, its envelope and building facade design is particularly important for engineering buildings, is the most critical position of light steel structure envelope seepage.

Steel structure maintenance system has its own compressive strength and bending stiffness, resulting in steel structure is usually not easy to seepage, maintenance system seepage reason is the key to the connection point treatment; The quality of raw materials, the maturity and perfection of the control system design, the structure and installation technology also endanger the moisture proof effect of the envelope system. The steel structure is closed and deformed due to the change of the natural environment and temperature, and the reinforcing bar connection position is offset. When the steel structure is closed, the general window seal can be used to deal with it.

Solution: The industrial building roof will have rotten drain, must use a shovel to remove one by one. Especially in the position of small screws, if you do not remove the brush with moisture-proof coating, soon the seepage will occur again. Solve the previous step, then carry out the preparation work before the brush. Mix in the construction paint first. A whisk is better. I can do without a latte. Then cut a piece of polyester cloth according to the protruding size. The next step is to brush and paint. Apply waterproof material to the clean and intact base surface. Use the paint method, not roller paint and brush. As a result of the brush coating can make up the building coating to every gap, and then more reasonable moisture. While the building paint is still wet, smooth the protrudes of the roof with a cut of polyester cloth. Then, the surface of the polyester cloth is coated with waterproof material, so that the architectural coating is sufficient to penetrate the polyester cloth, and the architectural coating can be fully combined with the bottom layer of the architectural coating according to the gap of the polyester cloth into a seamless splicing body. The solidified building coating layer is coated with a surface waterproof material that resists UV light.
