What problems need to be paid attention to in bathroom waterproofing?

Here are a few things to keep in mind:

1. The ground and wall should be all (full) waterproof. The wall should be made to a ceiling of 5 cm (not less than).

2. Before doing waterproofing, the structural leakage inspection must be carried out, and the irrigation test shall not be less than 24 hours, and the leakage shall be qualified (this is a mandatory inspection item before the delivery of the commercial house, including the kitchen with floor drain, so this detail should be paid attention to when the house is handed over).

3. Ground and wall leveling. This is generally completed before handing over, and the main thing here is to pay attention to the problem of flatness, and some have formed a certain slope.

4. Before doing waterproofing, all the reserved embedded pipelines must be arranged, and the base layer should be treated, and then the ground should be cleaned up, and there should be no floor ash or other garbage. It is necessary to pay attention to the pre-burial, not as a last resort, try not to chisel through the floor slab due to changing the pipeline, or break the structural layer, if it must be excavated, the structural waterproof inspection must be re-carried out after completion.

5. After that, it is the construction of waterproofing. The market is now generally waterproofing membranes and waterproof coatings. Because the construction process of the membrane is more complex and the quality requirements are higher, it is recommended to use waterproof coating for household use.

The specific construction process of waterproof coating can be checked on the Internet, and it will not be described here. Note: What brand of paint to check what brand of practice.

6. The waterproof materials of the wall and the ground can be made of different materials, which is mainly to consider whether the wall waterproofing will affect the adhesion of the tiles. At the same time, it is necessary to pay attention to the lap of waterproof joints, generally the ground waterproofing should be done to the wall (not less) 20 cm high, and the overlap joints are not less than 5 cm (ten cm is the best).

7. After the ground waterproofing is completed, it is best to make a 2-3 cm mortar protective layer, so that the waterproofing is completed.

Regarding the waterproofing of the bathroom, I can give you the following suggestions::

1.The first thing to pay attention to when doing waterproofing in the bathroom is the choice of waterproof materials, and it is recommended that you can directly use the waterproof slurry in the kitchen and bathroom, which is specially developed for the yin and yang angles that are easy to seep into the kitchen and bathroom, wear pipes, sanitary ware, floor drain peripherals, etc., so the special materials are dedicated, the pertinence is stronger, and the waterproof effect is of course better.

2.The construction of waterproofing should be carried out in accordance with the requirements of the manual, the proportion of waterproof materials, the standard thickness and height of construction, etc., so as to ensure a good waterproof effect.

3.After doing a good job of waterproofing, it is necessary to do a good job of sprinkling and maintenance in the later stage, and places with direct sunlight need to be covered and covered.

4.The base surface before waterproofing must be cleaned, there can be no oil and dust, etc., and it must be sprinkled with water to moisten, but there must be no stagnant water.

5.After the waterproofing is completed, remember to do a 48-72 hour closed water test to check whether there are any leaks in the waterproof construction and whether the waterproof function is normal.
