My shower room seeps water, knocks off the tiles, and redoes the waterproofing, but the downstairs s

Good waterproof materials, if done according to the standard, the waterproof of the mortar must be at least millimeter thick, like the thickness of the shower room. The thickness of the waterproof coating should be achieved, because the waterproof brush of the paint is relatively thin, so you must pay attention to protect it after doing waterproofing. For home use, the two-component waterproofing is better, and it is not recommended to use waterproofing membranes.

The most important thing to do waterproofing is to be careful, don't look for any waterproof company at every turn, they will only quote the price high, home waterproofing in the case of good materials, the construction is not too difficult, if you have time, not afraid of dirty, you can do it, buy a few buckets of good waterproof, according to the method on their barrels to do it, but don't miss the brush. You can also buy materials at a shop that sells waterproofing, and then ask them to call a worker to do it for you, just pay the wages.

Many domestic manufacturers are exploiting legal loopholes, and the mortar waterproofing is basically only done to say that it is okay, and their purpose is to make the same weight of materials can do more area than others, so as to improve their competitiveness. So when buying waterproof, don't just care about how many square meters their materials can be brushed, you will be fooled to see this standard.

If the water pipe is leaking, no matter how good the waterproof layer is, it is like filling a balloon with water, no matter how thick the balloon is, it will still be burst by the water.

So the key is not waterproofing, but preventing water leakage. If you do a good job of waterproofing, even if it doesn't leak downstairs, then you have an aquifer like a goldfish bowl under your floor.

The standard thickness of the coating waterproof is millimeters, and it may be less than 1 thickness in actual construction. You can stop using the water for two days to see if there is still a leak downstairs. If there is no leakage or the amount of water is significantly reduced, it means that you have not done a good job of waterproofing.

If it is still the same as before, it is explained that it belongs to the pipe. As long as it is well protected, the first choice for the bathroom is still paint waterproofing, and the price is 80-300 a bucket.

What about the pipes inside the walls.

In addition, some waterproofing materials do not need to be knocked off the tiles.

It may be that the waterproofing of the edge of the sewer pipe is not done, and when doing waterproofing, it must be made higher at the place of the sewer pipe, higher than the thickness of the paving floor tiles; Waterproof is not divided into thin and thick as long as it is done will not leak, the general waterproof is done 2-3 times, I don't know where you are, Beijing here Oriental Yuhong waterproof with more, the price of a move of about 70 yuan per square meter.

It depends on whether the waterproofing is done below the backfill layer and below the drainage pipe, whether the drainage pipe mouth is (key) waterproofing, polypropylene mortar, membrane, etc. Home decoration is recommended to use 5MM membrane The price is about 22 per square meter.

Do you make waterproof coatings? At a minimum, the waterproofing coating should be thick.
