彩鋼瓦的人總是聽到老師傅說一布三涂很關鍵，只要做好一布三涂，基本上施工質量就已經(jīng)決定了一半。說到這里，可能大家都很迷惑，這個一布三涂是什么？居然如此重要。

People with colored steel tiles always hear the teacher say that one cloth and three coatings are crucial. As long as one cloth and three coatings are done well, the construction quality is basically half determined. Speaking of which, perhaps everyone is confused, what is this one cloth three coats? Surprisingly, it is so important.

一布：

One cloth:

涂刷之前，需要對彩鋼瓦空洞部分進行填補，先使用合成高分子防水涂料對空洞的表面進行涂刷，再使用聚脂無紡布對空洞位置進行粘貼。

Before painting, it is necessary to fill the hollow part of the color steel tile. First, use synthetic polymer waterproof coating to paint the surface of the hollow, and then use polyester non-woven fabric to paste the hollow position.

三涂：

Triple coating:

底涂

Primer coating

就是在彩鋼瓦連接的接縫10到20公分寬的位置刷涂防水涂料，要均勻，厚度一致，然后還要檢查是否有空泡，有的話就要進行修補，然后就可以進行下一道工序了。

It is to apply waterproof coating evenly and uniformly at the joint of the color steel tile connection at a width of 10 to 20 centimeters, and then check for any bubbles. If there are any, they need to be repaired before proceeding to the next process.

中涂

Middle coating

就是將防水涂料刷在覆蓋在瓦上面的聚酯無紡布上，厚度要均勻，涂膜的厚度要控制在0.4mm左右，表面干了之后，可以嘗試著用手觸摸表面，看看是否粘手，不沾手的話就可以進行第三層涂刷了。

It is to brush the waterproof coating onto the polyester non-woven fabric covering the tile, with a uniform thickness. The thickness of the coating should be controlled at around 0.4mm. After the surface is dry, you can try touching the surface with your hand to see if it is sticky. If it is not, you can proceed with the third layer of coating.

面涂

Topcoat

專用的高分子防水涂料，使用油漆刷進行涂刷，均勻的進行涂刷，無流墜。涂刷之后厚度達到0.3mm。

A specialized polymer waterproof coating, applied with a paint brush, evenly applied without sagging. After painting, the thickness reaches 0.3mm.

所以這就是一布三涂的全部內容了，從而相信大家也能看出該施工操作對于彩鋼瓦的施工質量確實是起到非常關鍵的作用，因此在進行施工操作時，一定要認真操作，從而避免因為自己操作不當而影響一布三涂施工質量的可能。并且提醒大家，整個涂層的表面會在兩小時到六小時變干，但是需要二十四小時之后才能夠完全變干，這一點一定要多加注意。

So this is all about one cloth and three coatings, and I believe everyone can also see that this construction operation plays a crucial role in the construction quality of color steel tiles. Therefore, when carrying out construction operations, it is necessary to operate carefully to avoid the possibility of affecting the construction quality of one cloth and three coatings due to improper operation. And I would like to remind everyone that the surface of the entire coating will dry out in two to six hours, but it will take 24 hours to fully dry out. This must be paid more attention to.
