How to waterproof and repair leaks in hotels

1: Do a good job in the basic water and electricity projects. From a safety perspective, it is better to run the bathroom water pipes and wires above instead of below. However, many "guerrillas" are trying to save labor by running water and electricity on the ground, and even digging trenches and drilling round holes in the bathroom.

2: Clean the base and walls, and make the house waterproof, including the balcony, kitchen, and bathroom, but the focus is on the bathroom. First, use a small metal hammer to knock on the wall or floor. If you find a "pop" sound, it means there is a hollow drum inside, and you must knock out all the hollow parts. Then carefully clean the four wall bases and the ground, pull out the iron nails, clean up the debris and garbage, it is best to rinse them with clean water, and then wait for them to dry.

3: Do the first step of rigid waterproofing. The various sewer pipes in the bathroom can be left unchanged, so try not to modify them; if they need to be modified, you must not use cement mortar to fill the pores, and you must plug the leaks. Wang went to fill it out three times. The areas most likely to leak in a room are around the sewer pipes and the four corners of the walls, so these key areas should be paid special attention to. The area around the ground should also be blocked into three blocks with intervals. In this way, the ground is covered with a layer of rigid waterproof armor. A slope should be built inside the bathroom threshold, painted high to prevent water from flowing back into the outside room, and the threshold stone must be lightly filled with fine cement mortar to block leaks and wet paste.

4: The second level of elastic waterproof coating is good. After the new house is built and delivered, there will be some settlement. Over time, the hard elastic waterproof coating will be pulled apart due to settlement, thus losing Waterproof effect. Therefore, it is necessary to add a second insurance - elastic waterproof coating. Generally, the wall is moisture-proofed first, making it more than 1.8 meters tall. Because when people take a shower, water will splash onto the wall tiles. The molecular gaps between the tiles are large, and water molecules can easily enter the wall and penetrate into the wall of the opposite room, causing the paint on the back of the bathroom to fall off and the wallpaper to become moldy and discolored. After the walls are moisture-proofed, wall tiles are laid, and then the ground is decorated and waterproofed.
