If it's not a leaking sewer pipe and you don't want to make a big fuss, then there is a colorless and transparent waterproof coating on the market that can be directly brushed on the surface of wall and floor tiles.

You can purchase from a professional waterproof merchant. The above is for your reference.

Bathroom water seepage, it is recommended that you first need to find the cause of the water leak:

1. Find a professional hydropower worker to check whether the pipeline is ruptured and causes water leakage, etc., if it is a pipeline problem, it needs to be repaired in time.

repair pipes to solve water leakage problems;

2. If there is no problem with the pipeline, then consider that the waterproof layer is not done well and cause water leakage, if the local water leakage is serious, it is recommended to do the waterproofing again, so as to fundamentally solve the problem.

Bathroom waterproofing, it is recommended to use kitchen and bathroom waterproof slurry, because more than 80% of the water seepage in the bathroom is concentrated in the yin and yang corners, pipes, sanitary ware and other parts, so when doing waterproofing, these places need to pay special attention, you need to use quick-setting repair mortar to focus on repairing and strengthening these parts, and then deploy waterproof slurry to do waterproofing as a whole, so that the waterproof effect is better.
