What should be paid attention to when the bathroom is waterproof?
The first step of cleanup
The first step in waterproofing is to level it first. The so-called leveling is to level the original uneven surface and then do the waterproof construction. Before leveling, the surface will be cleaned of dust and impurities. Ensure the tidy and waterproof effect of the subsequent construction.
The second step is to pre-brush the leaky parts to waterproof
Often, the water leakage problem in the bathroom will mostly appear on the wall, corner or edge of the drain. The teacher should use waterproof paint to waterproof these places before doing formal waterproofing. This will make the place that is prone to leakage better waterproof and avoid hidden dangers in the future.
The third step is to formally waterproof
This is the most critical step. Not only should the waterproof coating be applied evenly on the ground, but also a distance of 30 cm to 50 cm above the surrounding walls. In addition, the shower area should be waterproof at least 1.8 meters high. In particular, pay attention to the joint between the wall and the ground must be painted evenly and slowly, and no gaps should be left.
The fourth step of maintenance and water test
After the waterproof coating is applied, it must be maintained for a period of time. After the coating is fully adhered to the base layer, a 24-hour water-closing test is carried out, but sometimes the leakage problem needs to go through one or two days, so it is best to do 48 to 72 hours. And after the experiment is completed, be sure to check the ceiling downstairs to see if there are any signs of seepage. In addition, if it is a sink toilet, it is necessary to pay attention to the waterproof before backfilling, which is much more important than the waterproof layer on the ground. If it is done well, even if the upper waterproof layer is not perfect, there will be no leakage.

Bathroom decoration waterproof skills
1. Make sure that the wall is waterproof. Before laying the wall tiles, make the wall waterproof. In general waterproof treatment, the wall surface should be 30 cm high, but for non-load-bearing light-weight walls, the entire wall must be waterproof, at least 60 cm high.
2. The joint between the wall and the ground and the joint between the pipeline and the ground between the water and the water are the most prone to problems. You must urge the workers to deal with these corners and corners, and the waterproof coating must be applied in place.
3.Re-lay the floor tiles to make the ground waterproof.If you need to replace the original floor tiles in the bathroom, after chiseling the original floor tiles, you must first level the ground with cement mortar and then do the waterproof treatment, so as to avoid the uneven thickness of the waterproof coating. Cause leakage. Before doing waterproofing, be sure to put the ground
Clean up.
4. Try not to damage the original waterproof layer. The newly delivered buildings are generally made with a waterproof layer on the ground. Therefore, leakage will not occur if the original waterproof layer is not damaged.
5. The decoration team is required to provide concrete root protection for the upper and lower water pipes of the bathroom, and paint the waterproof paint 10 to 20 cm from the ground, and then redo the ground for waterproofing, plus the original waterproof layer to form a composite waterproof layer to enhance Water resistance.
6. The groove of the water pipe in the wall should also be waterproof. During the construction process, when the pipeline, floor drain, etc. cross the floor, the waterproof layer around the hole must be carefully constructed. The water pipe is buried in the wall to achieve a reasonable layout, and the water pipe is laid to make a groove larger than the diameter of the pipe, the groove is plastered and smooth, and then the groove is painted with waterproof paint.
7. Use the 24-hour “water storage test” to check and accept the waterproofing. After the waterproofing project is completed, seal the door and the drain and fill the toilet floor with wate
