Coating technology: the construction technology to control the leakage of the outer wall of the coating decorative surface

Core tip: the main cause of the leakage of the exterior wall with paint facing is the cracking of the exterior wall paint The water penetrates into the insulation layer of the exterior wall from the cracks and is absorbed in it, and then penetrates into the wall structure and enters the interior wall The construction steps of the leakage of the outer wall of the paint decoration surface are as follows: place the safety sling → remove the hollowing and cracked paint layer → clear the cracks → handle the cracks → level the hollowing with waterproof cement mortar → brush JS composite waterproof paint as a whole 1 According to the construction requirements, the construction personnel shall arrange the safety crane for the parts requiring waterproof treatment Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: the main reason for the leakage of paint facing exterior wall is the cracking of exterior wall paint Water penetrates into the insulation layer of exterior wall from the cracks, and is absorbed in it, then penetrates into the wall structure and enters the interior wall The construction steps of the leakage of the outer wall of the paint decoration surface are as follows: place the safety sling → remove the hollowing and cracked paint layer → clear the cracks → handle the cracks → level the hollowing with waterproof cement mortar → brush JS composite waterproof paint as a whole 1 According to the construction requirements, the construction personnel shall arrange the safety sling for the parts requiring waterproof treatment, so as to carry out high-altitude operation 2 Chisel the paint layer of partial cracked and bulging exterior wall to the base layer of the wall, uncover the cracked coating at the joint of the window frame and the wall, and clean all the chiseled and fallen walls with soft brush to ensure that there are no loose particles such as dust, cement slag and loose paint blocks 3 Use anti-seepage plugging agent to fill all cracks and holes in the outer wall tightly, and seal the joint between window frame and wall and the wall gap with elastomer sealing material to cut off the leakage water source of the outer wall 4 Fill and level the cracking, falling off and excavation with waterproof mortar, and level with the original wall coating layer to ensure smooth surface and close combination with the wall 5 Mix JS composite waterproof coating into the required color 6 Apply JS composite waterproof coating on the wall as a whole, and the coating thickness shall reach a certain thickness for several times, subject to the best performance of waterproof materials Make the wall color even, flat and beautiful Because JS has strong elasticity and flexibility, the wall treated by the above method has the repair performance of micro cracks It can effectively prevent the exterior wall coating from cracking again At the same time, a large number of pores and micro cracks in the outer wall are closed by the waterproof coating, which makes it difficult for the rainwater to stay on the outer wall as if it falls on the lotus leaf, thus eliminating the source of water leakage, so as to achieve the purpose of waterproof Scope of application: roof: Waterproof of cast-in-place structure and assembled structure roof, especially suitable for slope roof waterproof and old roof renovation Underground engineering: facing water surface and back water surface waterproof Bathroom, kitchen, exterior wall, swimming pool and various pools are waterproof JS composite waterproof coating performance: JS composite waterproof coating is developed by improving Japanese patent technology, and the two component waterborne waterproof coating made of inorganic powder, such as acrylate polymer emulsion and cement, has high efficiency waterproofing effect It is a new waterproof building material with strong toughness and elasticity The material is a two-component waterproof coating composed of organic liquid material and inorganic powder material It has high elasticity of organic material and good durability of inorganic material It can be constructed on wet base surface, non-toxic, harmless and pollution-free, and can be prepared into a color surface layer 1 It is solidified by hydration of cement and volatilization of part of water It can be directly constructed on the wet base without open water, and has unique applicability to the environment where the base is not easy to dry and rainy season 2 Innocuous, harmless, pollution-free and easy to construct, it is an ideal environmental protection material for waterproof in drinking water pool 3 High bonding strength, the film is firmly and reliably bonded with various base surfaces and finishes, which not only plays a waterproof role, but also is conducive to the adhesion of finishes Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
