How to avoid the leakage of the color steel roof?

目前彩钢金属板被广泛应用于家庭自搭结构顶板，如自封飘窗顶、自搭房屋面。

At present, the color steel plate is widely used in the family roof structure, such as self sealing ceiling and self building.

在北方与彩钢板搭接的房屋原有立墙结构往往存在保温构造层，而后搭设的金属板材与墙体多数只是对接，未对结构墙面进行任何开槽固定等处理，在后期使用中因受风雨侵蚀、温度变化及使用年限影响，搭接部位密封不严实等很容易造成渗漏问题。

The structure of the original vertical wall structure of the building in the north and the colored steel plate often exists the thermal insulation layer, and the metal plate and the wall are only butted, and the structure wall is not fixed. In the later use, the lap parts are sealed because of the influence of the wind and rain erosion, the temperature change and the service life. It is easy to cause leakage.

Repair of bitumen

为避免渗漏问题发生或者渗漏后进行维修治理的方法各有不同，各出奇招，打发泡胶密封、涂刷沥青材料、卷材覆盖等等，但其防水治理效果也不尽相同，有些方法可能只是解一时之需，无法达到长期治理、补漏的效果。

In order to avoid leakage or leakage, the methods of maintenance and treatment are different. They are different, they send out the bubble gum seal, the bitumen material, the roll cover and so on. But the effect of waterproof treatment is not the same, some methods may only solve the temporary needs, and can not reach the effect of long-term treatment and leakage.

Cover maintenance

由于搭设的彩钢板多为彩钢夹芯板，即两层成型金属面板和中间发泡、熟化成型的泡沫、岩棉或其他隔热内芯组成。为有效密封搭接缝并防止雨水从板材缝隙向下部保温层串水，需对渗漏的彩钢板整体进行防水防护处理。

The color steel plate is mostly made of color steel sandwich panels, which is composed of two layers forming metal panels and intermediate foams, cured foams, rock wool or other heat insulation inner cores. In order to effectively seal the joints and prevent rainwater from the seam to the lower insulation layer, it is necessary to protect the leaked color steel sheet as a whole.

六大治理步骤

Six major governance steps

1

One

铲除清理

Eradicate cleaning

铲除金属板及金属板与墙体交接部位现有材料，对于局部防锈漆起皮的部分需清除，并清理板材接缝密封胶；

To remove the existing material from the metal plate and metal plate to the wall, the parts of the rust proof paint should be removed and the sealant of the joint sealant should be cleaned.

2

Two

基层清理

Grass-roots cleaning

大面清理浮灰，板材局部除锈打磨；

Large surface cleaning ash, plate partial rust and grinding;

3

Three

密封处理

Sealing treatment

扣板接缝、墙体结构交接部位重新打胶密封，并采用防水堵漏宝修补、抹弧；

The joint of the buckle plate and the wall structure is re glued and sealed.

4

Four

基层涂抹

Base coating

采用柔韧型防水涂料（如雨虹吉仕涂101）进行打底，薄涂一至两遍；

Use flexible waterproof coating (such as Yu Hong Shi Shi Tu 101) to underlay and spread it to two times.

5

Five

细部附加层

Detail additional layer

彩钢交接部位采用好仕涂屋面高弹防水涂料薄刷一层，然后铺贴网格布，保证其平整，无褶皱、翘边，最后在网格布上部涂刷好仕涂屋面高弹防水涂料，完全覆盖网格布。

At the junction of color steel, the high elastic and waterproof coating on the top of the roof of the color steel is used, and then the grid cloth is put up to ensure its smoothness, no wrinkles and warping edges. Finally, the high projectile waterproof coating on the roof of the grid cloth is painted on the upper part of the grid cloth, and the mesh cloth is completely covered.

大面涂刷防水涂料

Waterproofing coating with large surface brush

彩钢板整体涂刷防水涂刷屋面高弹，厚度达到1.5mm，要求薄涂多遍，每遍防水涂膜完全干燥后在进行下一遍涂膜施工。

The waterproof coating of the color steel plate is highly projectile with a thickness of 1.5mm, which requires a thin coating of thin coating, and the coating is carried out for the next time after the waterproof coating is completely dried.
