Common knowledge of coating: precautions for coating waterproof construction

Core tip: as the waterproof materials generally have good material properties, good waterproof performance, large adhesive force and extensibility, they can be constructed under normal temperature and can be applied to various complex shape structural bases, especially conducive to the sealing of internal and external corners, gutter free inlets and ends Therefore, it has been developing in the near future But in recent years, from the perspective of the use effect, the quality of waterproof engineering can not be ignored, the following small series will take you to understand the construction precautions 1 The dust and sundries on the surface of the base course to be coated with the waterproof layer must be cleaned The residual mortar hard blocks and protruding parts on the surface shall be leveled and swept, plastered, calendered, and the internal and external corners shall be cleaned 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 Home of coatings: as the waterproof materials generally have good material properties, good waterproof performance, strong adhesion and extensibility, they can be constructed under normal temperature and can be applied to the structural base of various complex shapes, especially conducive to the sealing of internal and external corners, gutter free inlets and ends Therefore, it has been developing in the near future But in recent years, from the perspective of the use effect, the quality of waterproof engineering can not be ignored, the following small series will take you to understand the construction precautions 1 The dust and sundries on the surface of the base course to be coated with the waterproof layer must be cleaned The residual mortar hard blocks and protruding parts on the surface shall be leveled and swept, plastered and calendered The internal and external corners shall be plastered into an arc or obtuse angle 2 The surface of the base course applied with the waterproof layer shall be dry, flat and firm, and shall be free of hollowing, cracking, sanding and other defects 3 At the root (edge) of the ground drain, pipe root, water outlet, sanitary ware, etc of the leveling layer, the head shall be rounded and smooth The slope shall meet the design requirements, and the components must be installed firmly, sealed tightly and accepted 4 The pipe root, floor drain, drain outlet, internal and external corners and other details protruding from the ground shall be reinforced with additional layer first, and the concealed works shall be inspected and accepted after the completion of waterproof coating 5 All kinds of materials used in the waterproof layer, such as base treatment agent and xylene, are inflammable They should be stored and kept away from the fire source During the construction operation, fireworks should be strictly prohibited 6 The construction of waterproof layer shall not be carried out in rainy and windy days, and the ambient temperature of winter construction shall not be lower than 5 ℃ 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,
