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

就是在彩钢瓦连接的接缝10到20公分宽的位置刷涂防水涂料，要均匀，厚度一致，然后还要检查是否有空泡，有的话就要进行修补，然后就可以进行下一道工序了。

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

就是将防水涂料刷在覆盖在瓦上面的聚酯无纺布上，厚度要均匀，涂膜的厚度要控制在0.4mm左右，表面干了之后，可以尝试着用手触摸表面，看看是否粘手，不沾手的话就可以进行第三层涂刷了。

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

彩钢瓦专用的高分子防水涂料，使用油漆刷进行涂刷，均匀的进行涂刷，无流坠。涂刷之后厚度达到0.3mm。

A polymer waterproof coating specifically designed for color steel tiles, applied with a paint brush, evenly applied without sagging. After painting, the thickness reaches 0.3mm.

所以这就是一布三涂的全部内容了，从而相信大家也能看出该施工操作对于彩钢瓦的施工质量确实是起到非常关键的作用，因此在进行施工操作时，一定要认真操作，从而避免因为自己操作不当而影响一布三涂施工质量的可能。并且提醒大家，整个涂层的表面会在两小时到六小时变干，但是需要二十四小时之后才能够完全变干，这一点一定要多加注意。

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.
