Waterproof and leak-patching in hotel bathrooms.

There are several steps for hotel waterproof and leak-patching:

1: Do a good job in hydropower foundation engineering. From the safety point of view, it is better for the water pipes and wires in the bathroom to go up, not down. However, in order to save labor, many "guerrillas" take water and electricity to the ground, and even open trenches and drill round holes in the bathroom.

2. Clean the grass-roots and walls and make the house waterproof, involving the balcony, kitchen and bathroom, but the focus is on the bathroom. First, hit the wall and the ground with a small metal hammer. If an empty drum is found, it means that there is an empty drum inside, and all the empty drums must be knocked out. Then carefully clean up the four wall foundations and the ground, pull out the nails, and clean up the miscellaneous soil and garbage. It's best to rinse it with clean water and then dry it.

3. Make the first layer of rigid waterproof, and all kinds of sewer pipes in the bathroom can remain unchanged, and try not to change them; If there is any modification, cement mortar shall not be used to fill the pores, and the leakage must be filled in three times. The most easily leaking places in the room are around the sewer pipe and around the corner, so special attention should be paid to these key parts. Around the ground should also be divided into three times, with intervals. In this way, the ground is covered with a hard waterproof armor. Toilet threshold should be sloped and brushed high to prevent water from flowing back to the outside room, and the threshold stone must be slightly smoothed with fine cement mortar.

4. The elastic waterproof coating should be done in the second level. There will be some settlement after the new house is completed and delivered. Over time, the hard elastic coating of the plugging king will crack alive due to settlement, thus losing its waterproof effect. Therefore, it is necessary to add the second insurance-elastic waterproof coating. Generally, the wall should be moisture-proof first, more than one meter eight. Because people will splash water on the wall tiles when taking a bath, the molecular gap of the tiles is large, and water molecules can easily enter the wall and penetrate into the wall of the opposite room, resulting in the paint on the back of the bathroom falling off and the wallpaper becoming moldy and discolored. After the wall is moisture-proof, stick wall tiles, and then make the ground decoration waterproof.

Master bang, it's more reliable to have insurance waterproof and leak-trapping service!
