卫生间防水施工工艺

一、材料要求
1. 聚氨酯涂膜防水材料（双组份），应有出厂合格证，应经复试合格后使用。
甲组份是以聚醚树脂和二异氰酸酯等原料，经过聚合及反应制成的含有端异氰酸酯基的聚氨基甲酸酯预聚物，外观为浅黄粘稠状，桶装，每桶20kg。
乙组份是由固化剂、促进剂、增韧剂、防霉剂、填充剂和稀剂等混合加工制成，外观有红、黑、白、黄及咖啡色等，膏状物，桶装，每桶40kg。
二、主要机具
1. 一般应备有电动搅拌器(功率0.3-0.5KW,200-500r/min)、搅拌桶(容积10L)，油漆桶(3L)、塑料或橡胶刮板、滚动刷、油漆刷、弹簧秤、干粉灭火器等。
三、作业条件
1. 涂刷防水层的基层表面，必须将尘土、杂物等清扫干净，表面残留的灰浆硬块和突出部分应铲平、扫净，抹灰、压不，阴阳角处应抹成圆弧或钝角。
2. 涂刷防水层的基层表面应保持干燥，并要平整、牢固，不得有空鼓、开裂及起砂等缺陷。
3. 在找平层接地漏、管根、出水口、卫生洁具根部（边沿），要收头圆滑。坡度符合设计要求，部件必须安装牢固，嵌封严密。经过验收。
4. 突出地面的管根、地漏、排水口、阴阳角等细部，应先做好附加层增补处理，刷完聚氨酯底胶后，经检查并办完隐蔽工程验收。
5. 防水层所用的各类材料，基层处理剂、二甲苯等均属易燃物品，储存和保管要远离火源，施工操作时，应严禁烟火。
6. 防水层施工不得在雨天、大风天进行，冬期施工的环境温度应不低于5℃。
四、操作工艺
1. 工艺流程.
清理基层表面→细部处理→配制底胶→涂刷底胶(相
Bathroom waterproof material

1, material requirements
1. Polyurethane waterproof coating (double component), should be factory certification, should be qualified by the re-testing before use.
Group A were based on polyether diisocyanate resin and other raw materials, through polymerization and the reaction products of isocyanate-containing polyurethane prepolymer base, look for the yellow sticky-like, drum, barrel, 20kg.
Group B were from the curing agent, accelerator, toughening agents, antifungal agents, fillers and processed into thin agent mixing, the appearance of red, black, white, yellow and brown, etc., pastes, drums, barrel 40kg.
Second, major equipment
1. General should have an electric mixer (power 0.3-0.5KW ,200-500r / min), stirring drum (capacity 10L), bucket (3L), plastic or rubber scraper, rolling brush, paint brush, spring, dry powder fire extinguishers.
Third, the operating conditions
1. Brushing waterproof layer of the primary surface must be dust, debris, etc. cleaned, the surface residual mortar lumps and protrusions should be leveled, sweep away, plaster, pressure does not, yin and yang corners into arcs or should be wiped obtuse angle.
2. Brushing the surface of base waterproofing layer should be kept dry, and to smooth, firm, not a void, cracks and other defects from the sand.
3. In the leveling layer of earth leakage, control roots, outlet, sanitary ware roots (edge), to receive the first slick. Slope meet design requirements, components must be installed on solid, inlay sealed tight. After acceptance.
4. Highlight the root surface of the pipe, floor drain, drain, Yin and Yang angle detail, should make an additional layer added to the treatment, after brushing polyurethane rubber bottom, concealed by the check and after finishing project acceptance.
5. Waterproof layer of various materials used, primary treatment agent, xylene, are flammable, storage and storage away from ignition sources, the construction operation, shall be strictly prohibited fireworks.
6. Waterproof layer construction may not in the rain, windy day for the winter period of construction of the ambient temperature shall be not less than 5 ℃.
4, the operation process
1. Process.
Clean surface of base → detailed treatment → → Paint the end of the preparation of underfill adhesive (as opposed to
