屋頂防水層是指在屋面下層上，抹壓或涂布具有屋頂防水能力的流態(tài)或流半態(tài)物質(zhì)，經(jīng)過溶劑、水分蒸發(fā)固化或交鏈化學(xué)反應(yīng)，形成具有相稱厚度并有肯定彈性的無接縫的完備薄膜，從而達(dá)到屋頂防水目的一種屋頂防水屋面情勢。
Bao Steel waterproof layer refers to the roof, or coated with a waterproof wiping pressure flow ability or bucket fluid material, solvent, water evaporation after curing or chain chemical reaction, forming a complete film without joints with considerable thickness and has certain elasticity, so as to achieve a form of waterproof waterproof roof.

涂屋面屋頂防水層前（成都人事考試），對下層必須認(rèn)真檢查和需要的處理，要求下層外觀平整、光潔、干燥（上海裝潢），不得有酥松、起砂起皮等征象。假如找平層平整度超過規(guī)定要求，則應(yīng)將突出部位鏟平，低凹處用摻有乳液的水泥砂漿修補(bǔ)填平或用聚合物水泥漿涂刷；起砂、起皮處應(yīng)將外觀消滅，用聚合物水泥漿涂刷并抹壓光。

Coated steel structure roofing waterproof layer, the base must be carefully checked and necessary treatment, neat, smooth surface, dry grass, there shall be no loose sand, peeling and other phenomena. If the leveling layer roughness exceeds the specified requirements shall be leveled the concave convex parts, mixed with cement mortar with polymer emulsion repair or fill slurry brushing; sand, skin at the surface shall be removed with polymer cement slurry brushing and wiping pressure light.

對基層驗(yàn)收合格后，涂刷與所用涂料材性相容的下層處理劑一道，以加強(qiáng)薇妮涂料與下層的粘接。
After passing the acceptance of the basic level, the coating and the coating material compatible with the basic treatment agent, in order to enhance the steel protection of the bottom surface coating and adhesive layer.

薇妮屋頂防水涂料涂刷前，下層上未先涂刷下層處劑或下層處理劑未燥及進(jìn)行施工。下層先涂刷下層處理劑，下層上存在的毛細(xì)孔未被堵塞，使下層上的潮汽向上滲入到聚酯布中，使聚酯布發(fā)生鼓泡，同時(shí)還會降低涂層與下層的粘接力。
Steel waterproof paint brush before brushing, the grass-roots level is not first brushing the agent or the basic treatment agent is not dry and construction. The base shows coating substrate treating agent base present in the pores are not blocked, so that the primary steam to penetrate into the edit tide type polyester cloth, polyester cloth has bubble, but also reducing the adhesion of coating and base.

因此為了加強(qiáng)涂層與下層的粘接力，在鋪貼防水聚酯布前，必須對已干燥的下層先刷一道薇妮彈性屋頂防水涂料，涂刷時(shí)要用力涂刷，使薇妮彈性屋頂防水涂料滲入下層毛細(xì)孔中，使之與下層牢固結(jié)合（網(wǎng)站制作報(bào)價(jià)），同時(shí)要等底面涂料干燥后方可進(jìn)行薇妮防水施工。
Therefore, in order to enhance the adhesion of coating and base, in paving for polyester cloth, must be dried grass first brush a steel Bao bottom elastic waterproof coating, coating to force the steel brush, treasure elastic waterproof coating into the base pores, which combined with the solid base firmly. At the same time to the bottom paint dry before the treasure of steel construction. The deposited ammonia nitrogen was decomposed and transformed.
