Because the kitchen floor and the external wall of the leakage, moisture, mold has become a common problem in the quality of housing, and there is a growing trend, often resulting in tenants of the trouble and disputes. In addition, if the kitchen does not do waterproofing, once the leakage, often have to knock open the ground, change the demolition of pipe fittings, is really troublesome! Kitchen waterproofing construction process is as follows: First, the material requirements 1. polyurethane coated waterproofing materials (two-component), there should be factory certificates, should be used after passing the retest. A component is a polyether resin and diisocyanate and other raw materials, after polymerization and reaction made of polyurethane prepolymer containing end-isocyanate base, the appearance of light yellow viscous, barrels, 20kg per barrel. B component is made of curing agent, accelerator, toughening agent, mildew agent, filler and diluent mixing and processing, the appearance of red, black, white, yellow and brown, etc., paste, barrels, 40kg per barrel. Second, the main machinery and equipment 1. generally should be equipped with electric mixer (power 0.3-0.5KW, 200-500r/min), mixing barrel (volume 10L), paint bucket (3L), plastic or rubber scraper, rolling brush, paintbrush, spring scales, dry powder extinguishers and so on. Third, operating conditions 1. painted waterproof layer of grass-roots level surface, must be dust, debris, etc. clean, the surface of the residual mortar hard lumps and protruding parts should be shoveled, sweeping, plastering, pressure is not, yin and Yang corners should be wiped into a rounded or obtuse angle. 2. painted waterproof layer of grass-roots level surface should be kept dry, and should be flat, firm, no bulging, cracking and sanding and other defects. 3. in the leveling layer ground leakage, pipe root, outlet, sanitary ware root (edge), to be rounded. Slope in line with the design requirements, components must be installed firmly, embedded tightly. After acceptance. 4. protruding from the ground pipe roots, floor drains, drain, yin and Yang corner and other details, should first do a good job of additional layer of additive treatment, after brushing the polyurethane primer, after checking and finishing the hidden project acceptance. The above is about the kitchen waterproofing process process to share, I hope you have some reference role! It should be noted that: waterproofing layer used in all types of materials, grass-roots treatment agents, xylene and other flammable items, storage and storage should be away from fire, construction operations, should be strictly prohibited smoke and fire. Satisfaction please point a praise, pro affirmation is my greatest power!
