Water seepage on the wall is a problem that many families will encounter. Once water seepage occurs on the wall, it may lead to cracking of the wall and appearance of mildew on the wall, which brings inconvenience to the daily home life. Therefore, when water seepage occurs on the wall, we should take measures to deal with it immediately. The following small series introduces the cause of wall seepage and the method of seepage treatment on the wall. Reasons for wall seepage 1, no insulation In the past, many houses had no insulation in the wall. In winter, the temperature difference between the interior and exterior was large. Therefore, the wall was cold and hot inside. The wall was high in temperature, so the condensate was formed on the wall, which caused the wall to be damp. Facing the wall, this situation generally only occurs in the winter, and it will be good in the summer, but the aftereffect is that it will leave a lot of unsightly mildew and affect the appearance of the wall. 2. Leakage of water pipes in the wall Walls caused by leakage of embedded pipes in the wall are generally damp. Generally, such conditions occur near the bathroom, or on the top of the house, or on the wall surface. Generally, there are leaks in the embedded pipe joints. Whether the water pipes in the walls of the home and the upstairs are leaky, the water in the partition wall infiltrates. 3, waterproof measures are not good The waterproof construction on the ground floor of the 1st floor did not do a good job of leaking the wall. The waterproof of the ground upstairs was not done well, and the waterproof of the toilet next door or the bathroom on the next floor was not good. Once the toilet had water, It will slowly penetrate. On the 2nd floor, there was no waterproofing at the junction of the water pipe and the ground. It is very likely that water seepage occurred near the pipe. The water ran down the pipe and caused the roof to seep. 4, improper paint In the paint project, when the wall was painted, the first time the wall paint did not dry out, it began to paint the wall paint for the next time. The water vapor in the wall failed to evaporate, resulting in the dampness of the wall. Wall seepage treatment method 1. Find existing water seepage points on the walls and cracks in the external walls. The entire peak of the smooth cracks cuts the interface between the masonry structure and the structural beam, the external wall plastering layer, the parapet layer of the parapet and the large cracking cracks on the external wall. In addition to using a hand-held cutting machine, the plaster layer is cut open to prevent new emptying due to vibration during removal of the plaster layer. 2. After removing the plastering layer, clean the grass and then lay a layer of wire mesh between the masonry and the structural beam to prevent the plastering layer from cracking again. 3, repair plaster layer, plaster layer repaired two to three times, and in the repair mortar mixed with a certain amount of micro-expansion agent to reduce the old and new plaster layer interface cracks. 4. After the plaster layer is dry, do exterior wall paint. Finally, after the wall paint is dry, apply one to two waterproof coats. Editor's summary: The reasons for the seepage of the wall and the method of seepage treatment on the wall are introduced here. I hope to help everyone.
