Wall plaster mortar, a product description wall plaster mortar is a new wall plastering material. Semi-water gypsum substrate polymer as gelling materials, inorganic filler by dry mixing together. Is a new and improved interior painting materials, changes in cement-based cementitious materials traditions, with a variety of substrates wall has excellent compatibility and adhesion. Second, the product advantages 1. crack, noise, heat insulation. 2. Automatically adjust the indoor humidity, a "breathing" function. 3. The strong bond, strong bond with the substrate, easy to crack. The good workability, simple construction. 5. The construction speed, short cycle. Third, the product scope 硂 wall, exterior wall of each household walls, aerated block, light sand filling block, brick and other substrate and each household wall compartment wall, every stairwell Thermal insulation. Fourth, the product standard: "SGF mixed mortar wall plaster application of technical regulations" JG / T015-2009 No. Item Unit Specifications 1 Appearance quality off-white granular powder 2 ---- Setting time initial setting h≥1.0 Final setting h ≤8.0 3 loose bulk density Kg / m3 1500 4 compressive strength Mpa≥5.0 5 water retention --- ≥90% 6 shrinkage --- ≤0.1% 7 combustion performance level ---- A level five, wall plaster mortar Performance comparison with cement mortar plastering Category Pros Cons Suitable substrates wall plaster mortar 1, good adhesion, for a variety of substrates. 2, light weight, construction workability, less ash fall. 3, setting hardening fast, saving period. 4, drying shrinkage, not hollowing cracking. 5, fire function well, can mediate indoor humidity. 6, low cost, good environmental protection, energy-saving effect. 1, the use of shorter mortar. 2, workers need to adjust the construction habits. Situ concrete aerated concrete polystyrene board and a variety of insulation products, cement mortar slurry of fly ash bricks 1, high strength. 2, water resistance. 3, the traditional plastering material, easy to use. 1, poor adhesion, easy to produce hollowing. 2, shrinkage, easy to crack. 3, the operation more ash fall. Suitable for six brick construction construction process preparation → primary treatment → Wall stickers cake → preparation → 1:2 wall plaster mortar layered bottoming → pure wall plaster overlay. 3.1 ready to use pre-construction deal with wall plaster relevant examination, according to the factory quality certificate, performance test reports, manual, etc., with the necessary test pressure test, grasp the intensity of wall plaster case, caking, damp wall plaster Mortar shall not be used. Mixing water use drinking water. Gather iron trowel, wooden float, care gray board, gray pots, 2m aluminum scraping feet and other plastering tools and shovels, unified specification tin barrels, making the mix of gray metal grooves and other tools. The wall plaster mortar shipped to Face. 3.2 Primary treatment will be part of the primary surface irregularities flat patch tick, dust, debris clean, regular watering and humid; in concrete and masonry ceramic concrete (aerated concrete masonry) phase at wide paving ≥200mm big eyes glass screen. Glass screen to be pasted firm, smooth, in a tight state, shall not exceed the pre-control plaster layer thickness. 3.3 formulation slurry wall plaster mortar into the mix tank, slowly add water wet mix until the convenient operation. During the construction process should be strictly controlled batching workers, ensure the strength of wall plaster mortar. 3.4 when rendering plaster thickness> must be strictly hierarchical leveling when 8mm, thickness control of each layer in bottom ash 5 ~ 8mm, pending the final set and then wipe down layer layer; scraping along the wall vertical and horizontal ruler direction close to the ash cake scraping to find, until leveling up, rub with a wooden trowel compacted hair. Base flatness is not required to meet the requirements bottoming directly overcoat with mortar wall plaster surface. After 3.5 overcoat bottom ash hardened final setting, you can be overlay; plaster stucco overlay pure operates in two passes survived thickness control at about 2mm, the first pass is used to make flat gray mortar and trachoma enhance the adhesion between the overcoat ash and bottom ash, the second time for calender gray overcoat, calendering ≥3 times the number of passes, in order to ensure that the surface bright and smooth, consistent color. 4 Note (1) the wall plaster in the storage and transportation process should prevent moisture and storage time not too long, in principle, should be used up within three months; the use of a small amount of lumps found, use should be sifted. (2) The initial setting time of mortar wall plaster general ≤1h, final setting time ≤4h; it is not a gray mortar mix when mixing too much, to avoid the water in the course of the second mix used to make wall plaster strength is reduced or loss, resulting in rework losses. (3) the construction is completed, to promptly clean up the doors and windows, water and line pipe, structural layers, etc. residual mortar. Strengthen product protection, maintain indoor dry and well ventilated. (4) applies only to inter-wall plaster dry indoor environment, bathroom, kitchen and other moist environments is strictly prohibited
