1、 表面清洁——清除表面杂物、油污、砂子，凸出表面的石头、砂浆疙瘩等应清理干净，清扫工作必须在施工中随时进行。
Remove surface debris, oil, sand, stone protruding surface, mortar lumps, etc. should be clean, clean-up work must be carried out at any time during construction.
2、 强度——为保证涂膜牢固粘结于基层表面，要求找平层应有足够的强度，表面平整，不起砂，不起皮。对于不满足强度要求的基层，应将低强度的表面凿去，用聚合物砂浆或其他高粘结性砂浆进行修补平整。
To ensure the coating is firmly bonded to the base surface, requiring leveling layer should have sufficient strength, smooth surface, sand can not afford, can not afford leather. Does not meet the strength requirements for the grassroots, low-intensity surface should be chipped away, with a polymer mortar or other high repair mortar adhesion formation.
3、 坚固——防水基面的混凝土或水泥应达到一定强度后才能施做防水，并无松动、空鼓块体。
After the concrete or cement-based waterproof surface reaches a certain intensity should be applied waterproof, no loose, hollowing block.
4、严禁在雨天进行防水卷材和保温施工，卷材防水层的找平层要符合质量要求，达到规定的干燥程度。
Prohibited conduct in the rain waterproofing membrane and insulation construction, waterproof membrane layer of leveling layer to meet the quality requirements, to the extent specified dry.
5、防水卷材铺贴时要避免过度拉紧和皱折，基层与卷材间排气要充分，向横向两侧排气后用辊子压平粘实。
Stones when waterproofing membrane to avoid excessive tension and wrinkles between the primary and the coil exhaust to the full, to the lateral sides of the exhaust rollers flatten sticky solid.
