believes that in our daily lives, we can see leaks in many indoor corners and bathroom walls. Most people think that it is caused by long-term rain or water flushing from the bathroom. This analysis is relatively one-sided. The editor has sorted out the causes of bathroom wall leakage and helps you solve them.

First of all, let’s share the reasons why the bathroom wall is leaking

Cause 1: Water pipe leakage

Ask a professional plumber to use a pressure detection device to detect the water pressure of the pipe. When the working pressure is 1.15 (about 4.6kg) times, the pressure is stabilized for 2 hours, and the pressure drop should be No more than 0.03MPa (about 0.3kg). If it exceeds the above range, the water pipe is leaking and the water pipe needs to be reinstalled.

Cause 2: The waterproof layer of the wall is broken

Continued from the above, if it is not a problem with the water pipes, then the waterproof layer of the wall is broken, and the waterproof layer needs to be remade.

Solutions to bathroom wall leakage

In terms of home waterproofing, membrane waterproofing is generally rarely used because there are pipes, wires, etc. on the home wall.

The specific waterproofing methods for bathroom walls are as follows:

1. The ground should be sloped in the direction of the floor drain. Cement mortar or pisolite concrete can be used, but the surface must be smooth. The slope near the door is small, and the slope near the floor drain is large. It should be determined according to the specific situation.

2. The pipeline passes through the root of the floor slab to enhance waterproofing. The pipe root is sealed tightly with sealant, and the cement is smoothed to protect the feet. When applying waterproof coating , apply 1 to 2 layers of glass fiber cloth reinforcement layer, and the same measures are taken near the floor drain.

3. The floor should be clean and smooth without floating dust and small particles, and small original corners or slopes should be applied at the intersections of the walls. When applying waterproof coating, apply 1 to 2 layers of glass fiber cloth reinforcement layer.

4. The total thickness of polyurethane waterproof coating film requires more than 1.5 mm. It cannot be determined by the number of passes. Brush the pipe root and wall corner reinforcement layer first, and then apply and scrape on a large area after surface drying for 4 hours at room temperature. There must be no leakage, scraping or bubbling. Paint a large area and allow 24 hours to cure before applying the next layer.

5. Paint the facade first and then the flat surface. The next painting direction is perpendicular to the previous one. When the last coat of coating is semi-cured, throw in the coarse sand to facilitate future combination with cement mortar .

6. Solution to water seepage in the exterior wall of the bathroom - The ground waterproofing layer should be painted 300 wide beyond the bathroom door opening. Waterproof ground waterproof layer should be 200 meters above the ground.

If there is water leakage on the wall, you need to deal with it quickly, otherwise the problem of cracking and mold on the wall will be even more troublesome. Okay, today I will share some waterproof knowledge here. Please continue to follow me to get more waterproof knowledge
