1、 表面清潔——清除表面雜物、油污、砂子，凸出表面的石頭、砂漿疙瘩等應清理干凈，清掃工作必須在施工中隨時進行。
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、 強度——為保證涂膜牢固粘結于基層表面，要求找平層應有足夠的強度，表面平整，不起砂，不起皮。對于不滿足強度要求的基層，應將低強度的表面鑿去，用聚合物砂漿或其他高粘結性砂漿進行修補平整。
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、 堅固——防水基面的混凝土或水泥應達到一定強度后才能施做防水，并無松動、空鼓塊體。
After the concrete or cement-based waterproof surface reaches a certain intensity should be applied waterproof, no loose, hollowing block.
4、嚴禁在雨天進行防水卷材和保溫施工，卷材防水層的找平層要符合質量要求，達到規定的干燥程度。
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、防水卷材鋪貼時要避免過度拉緊和皺折，基層與卷材間排氣要充分，向橫向兩側排氣后用輥子壓平粘實。
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.
