Methods to prevent dewing on the wall analysis of the causes of dewing on the wall

Every winter, condensed water is very easy to appear on the wall. This is because the temperature difference between indoor and outdoor is too large in winter and the air circulation is not smooth. The condensed water on the wall will make the wall skin fall off quickly, and the wall skin will grow hairy after a long time, which will seriously affect the health. Once there is condensed water on the wall, it should be treated in time, and there are many treatment methods. The following small series introduces the methods to prevent dew condensation on the wall.

A, the wall to prevent condensation water method

1. Replace or repair the water pipe directly: If it is caused by the water pipe, you can replace the water pipe or temporarily repair it with the special tape for repairing the water pipe first. The specific operation method is: first close the valve and cut off the water supply, then open the faucet to a suitable position to release most of the pressure in the water pipe, and then tie the leaking part with special adhesive tape or seal it with epoxy resin glue.

2. Contact the property: any problems involving the external wall should be reported to the property, and the property should contact the engineering department for maintenance.

3. Waterproof paint: Owners with water leakage at home can buy waterproof paint and paint the bathroom walls and floors themselves. The best way is to ask the decoration workers to solve it, which is more professional and effective. Or waterproof it again, it will be a little troublesome.

Second, the analysis of the causes of dew condensation on the wall

1, water pipe leakage to judge the water pipe problem: first, look at the direction of the water pipe according to the construction drawing. If there is a water pipe buried behind the leaking position, you can turn off the sluice at home and clean up the water in the faucet when you are traveling or not at home. If the water mark on the wall disappears after a while, it proves that there is something wrong with the water pipe.

2, the waterproof layer leaks to judge the waterproof layer problem: after the shower, the back wall of the bathroom leaks, and after a period of time, it is found that the wall leakage has improved, which proves that there is a problem with the waterproof layer.

3. Waterproofing is not done well: Speaking of this, I have to remind everyone that waterproofing must be checked and accepted, otherwise it will be regretted if such a bad thing happens. Since waterproofing is not done well, we can only do it again. This step is still more troublesome. It is necessary to completely destroy the wall tiles and shovel off the old waterproof layer. Starting from leveling, fill the cracks with waterproof paint step by step.

4, water pipe leakage: water seepage caused by water pipe leakage, the first step is to find the source of water seepage, that is, the device of water pipe leakage; In fact, this is more difficult, after all, there are some hidden pipes that we don't know. However, according to the experience of water leakage, it is generally more likely to be at the location of water pipe joints.

5. Improper painting: In the painting project, when painting the wall, the wall paint was not completely dried for the first time, so when painting the wall paint for the next time, the water vapor in the wall failed to volatilize, resulting in the wet wall.

6. No insulation layer: In the past, many residential walls had no insulation layer. In winter, the temperature difference between indoor and outdoor is large, so it is cold outside the wall and hot inside. Due to the high temperature of the inner wall, condensed water will form on the inner wall, resulting in the inner wall being wet.

When there is condensed water on the wall, it should be treated according to the above method. If the situation is serious, contact the property management in time. The above is the method of preventing wall condensation introduced by Bian Xiao, and the analysis of the reasons for wall condensation.
