The bathroom floor has not been remodeled, whether it needs to be re waterproofed

Waterproofing is no longer a new topic, whether it is tunnels, bridges, embankments, roads, buildings or the houses we live in every day. At the same time, electrical products used in daily life also have the problem of waterproof and moisture-proof that must be faced.

Waterproof is best to find a professional waterproof company to do, otherwise once there is a leakage will be very troublesome, the waterproof layer must extend from the ground to the wall, 250MM higher than the ground The height of the waterproof layer of the bathroom by the shower head wall shall not be less than 1800MM, the floor drain is directly done on the original base layer, and then do waterproofing, but the ground will be raised, the floor drain should be particularly carefully waterproofed, sealed with plugging treasure or polyurethane sealing paste, and then the overall coating waterproof layer, must be painted carefully around the floor drain, Finally, the surface is treated as a whole.

After reading your question, I analyzed the situation you said is "after buying a new house or a second-hand house, I changed it slightly, and found that the layout of the bathroom is still very reasonable, so I don't want to change it, the original sewer is still the original, and the developer also made waterproof when handing over the house, so you want to if the bathroom floor is not changed, you don't want to do waterproofing, just want to directly paste tiles on it" Here I will tell you for sure, if your home is the first floor, you don't need to do it again, but if not, There are several reasons why it is necessary to do it:

1. The waterproofing made by the original developer does not carry out closed water experiments, so no one dares to say whether it leaks or not.

2. When doing hard work in the bathroom to dig ditches or change water and electricity, it will inevitably hurt the original waterproofing of the ground.

3, after the end of the bathroom water and electricity, I have redone the waterproofing, and then carry out the closed water experiment for 24 hours (the closed water experiment is to store water on the bathroom floor), go downstairs to see, if there is no leakage, the bricklayer can rest assured that the bricks, or it will be very busy in the future, 4, bought a house, the waterproofing of the concealed project is too important when decorating, so the strong Jianyi Building mainly re-does the waterproofing, which is the responsibility for itself.

5. In the past, there were customers who used the original waterproof, did not redo it and then leaked downstairs, and finally re-planed the bricks, and was depressed for a while.

6, just say these first, if the landlord still has something unclear, please ask me,

There is no leakage on the bathroom floor, and there is no need to re-do the waterproofing if the decoration of the floor is not knocked off and the floor decoration plan is redone.

What does it mean to not have a makeover? Is it a renovation of an old house? If the floor tiles are removed, they must be re-waterproofed, and the water test should be turned off.

To do it, the floor has not touched the wall?

It is necessary to do waterproofing for the decoration of new houses.

First of all, the bathroom should be turned off when the house is handed over, and the decoration can be started when you go downstairs to check that there is no water leakage.

After the concealment of the buried pipe is completed, the backfill surface should be leveled with cement mortar. After completion, do the waterproofing again, and then turn off the water test, and then start tiling when there is no leakage.
