Coating technology: Construction Technology of acrylic waterproof coating

Core tips: 1 Process flow Clean the base course → waterproof layer on the bottom → additional layer on the details → brush the middle waterproof layer → lay the reinforcing layer → brush the middle waterproof layer → brush the surface waterproof layer → the first water storage test of the waterproof layer → construction of the protective layer and the facing → the second water storage test → project quality acceptance 2 Key points of construction (1) Clean the base course: the surface of the base course must be cleaned carefully It is required to be solid, flat and dry; base slope Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Paint Home News: 1 Process flow: clean the base course → waterproof layer on the bottom → additional layer on the details → brush the intermediate waterproof layer → lay the reinforcing layer → brush the intermediate waterproof layer → brush the surface waterproof layer → the first water storage test of the waterproof layer → construction of the protective layer and the facing → the second water storage test → project quality acceptance 2 Key points of construction (1) Clean the base course: the surface of the base course must be cleaned carefully It is required to be solid, flat, without sand, and basically dry; the gradient of the base course shall meet the design requirements, without ponding (2) Brush the bottom layer: pour the acrylic coating into an empty bucket for about 2 / 3, dilute with a little water and stir fully, brush the bottom layer evenly with a roller brush, with a dosage of about 0.4 kg / ㎡, and carry out the next process when the hand is not touched (3) Detail additional layer: inlay sealing paste: inlay sealing paste in the groove of the pipe root and other parts according to the design requirements The sealing material shall be tightly pressed to prevent the air from being wrapped, and it shall be firmly bonded with the joint wall, without cracking, bubbling and falling The grooves in the leakage prone parts such as floor drain, pipe root and internal and external corners shall be leveled with acrylic paint A layer of matrix reinforcement material shall be added to the weak parts of floor drain, pipe root, internal and external corners and entrances which are prone to water leakage The width shall not be less than 300 mm, and the lap width shall not be less than 100 mm During construction, the acrylic waterproof coating shall be applied first, then the reinforcement material, and then the acrylic waterproof coating shall be applied twice (4) Painting middle and surface waterproof layer: take acrylic waterproof coating and apply it evenly on the bottom waterproof layer with roller brush, each time is about 0.8-1.0kg/m2 The lower reinforcement layer and middle layer must be constructed continuously without interval If the thickness is not enough, one or more layers shall be applied to meet the thickness requirements of the film specified in the design (5) In the first water storage test, after 48 hours of dry consolidation of all waterproof layers and 24 hours of water storage, it is qualified if no leakage occurs (6) After the first water storage of the protective layer or facing layer is qualified, the protective layer or facing layer can be made (7) The second water storage test After the interior decoration works are completed, the second water storage test shall be conducted before the completion of the works to check whether the waterproof layer is damaged after completion It is qualified if there is no leakage after 24 hours of water storage test 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,
