True stone QiChang home: water bag water paint construction process

Water bag water color paint is water-based environmental protection coating system, a series of products, is in order to meet the growing born for building exterior wall coating market. Also known as water package colorful coating the horizon. Made from high-tech development of the modified resin and pigment, stability is good. It is a one-time spraying water color granite coating, all of them, and produce more vivid and durable color. According to the designers, granite samples of simulation degree can reach 99%, is a good product instead of external wall of granite. Here is water bag water construction process are briefly introduced: 1. Outer wall surface treatment: the outer wall surface treatment before is the key of the coating. Sturdiness and durability of the coating to a great extent, through good surface treatment. Surface should meet the following requirements: before strong, completely dry, neutral or slightly alkaline, clean. New wall and not the lacquer on metope processing: (1) check for cracks, holes and metope rough, according to the situation in 1:3 ~ 4 fine cement mortar to fill. When the wall is too rough, paint consumption will be doubled. (2) check for signs of water pipe leaking walls if there is leakage, water source should be ruled out. (3) check the bridge after the wall is completely dry. When it's too dark on the surface of the building, said the moisture content is too high. Moisture meter is used to inspect before painting, Moisture content should be lower than 8%) Should gray metope, completely dry is relatively uniform, the ph value should not be higher than 10. The summer concrete walls around the need to maintain the above commonly, winter should be extended accordingly. (4) when to decorating roughness have special requirements, you can use special exterior wall putty ( BoErPing putty layer too thick, otherwise easy to crack. After leveling, need to wet curing many times, until the ph less than 10, the water content below 8%. ( Exterior wall coating is best not to blow be bored with child, so can reduce the adhesion, alkalization, cracking, etc. ) 5. When the wall high basicity, construction progress faster, can take the following steps: 1. With 5% oxalic acid solution to clean the wall until the ph value is lower than 10; Clean with clear water wall; C, make wall dry moisture content is less than 8%. External thermal insulation system wall surface treatment: (1) check whether there is loose in the external thermal insulation surface protection rubber accessories, grease and pollutants, if any, remove or cleaning. (2) according to the roughness of external thermal insulation system wall surface protection glue, selecting special exterior wall putty for scratches, to meet the requirements of surface decoration decoration. Then in accordance with the provisions, maintenance to the ph value is less than 10, moisture content is less than 8%.
