出色底層表面的尖銳硬物、砂漿疙瘩等根除，不能根除時(shí)應(yīng)選用水泥砂漿抹面掩蓋處置，抹面圓弧半徑應(yīng)大于300mm。并將塵土雜物根除潔凈，陰陽角、管根部等處更應(yīng)仔細(xì)收拾，若有不一樣污漬、鐵銹等，應(yīng)以砂紙、鋼絲刷、溶劑等根除潔凈。
Well bottom sharp hard object, the surface mortar bumps cannot eradicate eradication, should be used with cement mortar to cover treatment, surface radius should be greater than 300mm. And the dust impurity eradicate clean, yin yang angle, pipe root should be more carefully pick up, if not the same stains, rust etc., should be based on the sand, steel wire brush, the eradication of clean solvent.
平立面交接處的陰陽角均應(yīng)做成均勻一起、平整光滑的圓角，陰角圓弧半徑不小于50mm，陽角圓弧半徑不小于20mm；防水材料及系統(tǒng)配件需保存在通風(fēng)、單調(diào)的當(dāng)?shù)兀⑦h(yuǎn)離火源，應(yīng)避免日曬、雨淋。
Facade junction of the yin yang angle should be made uniform with smooth, rounded, corner radius of not less than 50mm, corner radius of not less than 20mm; waterproof materials and accessories must be maintained at the local ventilation, monotonous, and away from the fire source, should avoid the sun, rain.
底層表面應(yīng)平整光滑、均勻一起，其平整度用2m直尺檢查，最大空位不大于5㎜，且每米不多于1處；底層需要無明水即可施工卷材，需熱熔粘貼施工的底層表面應(yīng)盡可以單調(diào)，含水率宜小于9%。測(cè)定方法是：將1㎡的卷材掩蓋在底層表面上，靜置2～3h，若掩蓋的底層表面無水印，且緊貼底層一側(cè)的卷材亦無凝結(jié)水痕，即為符合粘貼施工需要。
The bottom surface should be smooth, uniform, the flatness of 2m ruler examination, the maximum space is not greater than 5 mm per meter, and no more than 1; the bottom need no Mingshui to construction material, the bottom surface needs to be hot melt paste construction should as far as possible the monotone, moisture content should be less than 9%. Determination of the method is: will roll 1 ㎡ cover on the bottom surface, standing for 2 ~ 3H, if the underlying surface cover no watermark, coil and close to the bottom side of the no condensed water mark, is consistent with sticking construction need.
