The bathroom waterproofing is not done well, what is the remedy?

There are some summary remedies, but they are limited to the circumstances, conditions, time and responsibilities that can be used by those who have time, patience and care. It is still recommended to remake the waterproof in order to get away with it once and for all.

These temporary measures can only be used after making sure that there are no pipeline leaks:

If it is determined that the backfill layer or wall is caused by the leakage of water in the gap, the gap can be cleaned and then filled with weather-resistant sealant, which is limited to the place where the water can be quickly drained if there is not often water, and my family has used this method.

If it is only a floor drain leakage and is not stepped on, you can clean and dry the film-forming waterproof coating within a certain range of this part several times, and turn it into the floor drain socket each time. Other ground drains can also be treated by analogy.

If there is moisture seepage on the wall of the shower room, you can paste waterproof wallpaper or install colored stainless steel plates to keep water and moisture out.

Of course, there are some new methods, and the effect needs to be verified. In short, we should pay attention to the functional room with special conditions and complex technological processes in the bathroom, reduce rework, reduce the impact, and create a harmonious society.

What is the extent of the failure you said, whether it is a large-scale leakage or waterproofing, powdering, cracking, etc., different severity has different treatment methods, but the most fundamental solution is to redo waterproofing!

I had to start over, as if there was no other way.

Only by reworking and starting over, otherwise the consequences will be endless......! Good luck!
