Hello, after the floor tiles leaked in my bathroom, I opened all the floor turns, and the water did

Since K11 (should be JCDecaux's waterproof slurry), as long as the construction is in place, there is no need to paint polyurethane. Because cement-based waterproof coatings have long-lasting and excellent waterproof performance as long as the construction is in place; At present, the polyurethane waterproof materials on the market are generally not environmentally friendly, not suitable for home decoration, and the compatibility of the waterproof layers of two different materials is also insufficient.

Generally, do not use two waterproof materials to do waterproofing, easy to chemical reaction, if a layer of waterproof is not stable, you can use the same material to brush again.

The cause of the water leakage has not been found, can blind leveling and wall brush waterproof slurry solve the problem? (It may not leak downstairs, but when the floor tiles are saturated, the water will seep into the surrounding walls, or overflow through the joints of the floor tiles).

The upstairs is good... It doesn't feel good that you can stick polypropylene.

You should pay attention to the details, if on the basis of waterproofing, first do a good job of drainage and then do waterproofing is the right way, more information, better advice, free concrete waterproof leakage repair technical advice, to avoid today's repair, tomorrow's leakage, every year repair, every year leakage troubles.

If it's oily polyurethane, don't use it, it can't be well bonded with K11, if it's water-based polyurethane, then it's no problem, you can brush it.

However, the test water is already leaking, so why brush it again?

The smell of polyurethane is more carcinogenic, so it is not recommended! The best thing to do is if the leak is found? If not, first add cement ash and water to stir with water, brush to the edge of the wall corner, pipe mouth, feel that there will be water leakage, and brush other places again, and so on, buy a little Sika flexible waterproof, not expensive, come back A and B 1 to 1 ratio, modulation and stirring evenly, the main corner pipe mouth, the leakage of a little bit, others also brush, the wall to the wall brush as high as the brush, for the sake of insurance!

After it dries, put some water for 24 hours, and there is no problem with tiling! In this way, you can not only ensure water leakage, but also ensure your own health!

Be sure to go downstairs to see the location of your water leakage, check whether it is the water pipe rupture caused by the leakage, if it is not the water pipe rupture then you can follow the above method, if the water pipe is broken, directly repair the water pipe and then according to the above construction, if there is no way to check the water pipe, it is recommended to suppress the test-) I hope it can help you!

You can use water-based polyurethane, the material is non-toxic and odorless, there is no problem in construction in humid environments, and the blister-resistant and waterproof performance is better than K11.

Yes, but when it's done.
