Common knowledge of coating: matters needing attention in the construction of exterior wall coating

Core tip: as the name implies, exterior wall paint is the paint used on the exterior wall of the house, which generally has the effect of waterproof and sunscreen The house is easy to be damaged and shabby in the long-term water and sun exposure The exterior wall paint project can enhance the water and sun resistance of the house, maintain the decoration and prolong the service life A coat is put on the outer wall and a protective film is added With years of experience in exterior wall construction, the head Mommy tells you what to pay attention to 1、 High rise wall waterproofing The wall is a vertical component of the building, but it will be introduced due to design, construction, material, use and other factors Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: as the name implies, exterior wall paint is the paint used on the exterior wall of the house, which generally has the effect of waterproof and sunscreen The house is easy to be damaged and shabby in the long-term water and sun exposure The exterior wall paint project can enhance the water and sun resistance of the house, maintain the decoration and extend the service life A coat is put on the outer wall and a protective film is added With years of experience in exterior wall construction, the head Mommy tells you what to pay attention to 1、 The high-rise wall is a vertical component of the building, but because of the design, construction, material, use and other factors, the wall will crack, resulting in leakage 1 The leakage control method of the wall is used to repair the original structural waterproof The linear structural waterproof is used to disperse the water When the cavity structure is damaged locally, the restorative repair is effective 2 The method of repairing with waterproof material is widely used, that is to say, the method of caulking or brushing with oil soluble or water emulsion waterproof material is used in the part of rainwater infiltration room Waterproof measures shall be taken at the outer side of the outer wall panel to waterproof the wall through waterproof materials 3 The water blocking method of external wall internal coating is to take waterproof measures at the half inner side of the external wall to block the rainwater intrusion through waterproof materials The construction strength is high-altitude work, and professional technicians are assigned to survey, separate and formulate construction plans for all kinds of waterproof repair works Therefore, there is no need to set up scaffolding for high-rise external wall waterproof and leakage stoppage to save auxiliary expenses 2、 Exterior wall construction coating construction 1 The bottom layer of exterior wall coating of new wall construction requires sufficient maintenance period, and the new cement mortar concrete surface must pass a reasonable maintenance period to make it "spit alkali" and fully dry The surface of the bottom layer shall be dry, solid and firm, and free from sand, crack, loose and other defects 2 Construction method: the external wall coating should not be applied with putty in large area, the putty layer should not be too thick, and the material should be polymer cement putty Generally, one coat of primer and two coats of surface coating are used According to the project quality requirements, the number of surface coating can be increased appropriately The painting construction is generally carried out from top to bottom, and each painting shall be bounded by dividing line, wall surface, internal and external corner joint or downpipe 3 Generally, roll coating, brush coating or air spraying and airless spraying are used for operation tools 4 Paint is used to decorate the surface of buildings for maintenance and renovation The biggest advantage is that it can be renovated in a certain period of time Generally, comprehensive maintenance is carried out for buildings in 4-5 years Before the renovation of the external wall construction, a comprehensive inspection shall be carried out and a construction plan shall be formulated 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,
