What to do if the waterproof layer of the bathroom is cracked

The cracking of the waterproof layer is generally caused by the dry shrinkage crack caused by the excessive thickness of the coating during construction.

These cracks are especially reflected in the corners, pipe mouths and uneven base surfaces, these parts are the key parts of waterproof construction, and the construction personnel often carry out multiple brushing without complete surface drying, resulting in excessive thickness of the coating film, and dry shrinkage cracks are caused by the difference in the cold shrinkage coefficient of the thermal barrier, which will lead to water seepage in serious cases.

It is recommended that a single brush should not be too thick, not more than 1mm, and wait for the previous brush to be basically dry (just not sticky) when applying multiple times.

1. Waterproof layer leakage: the original ceramic tile needs to be removed, the base surface is cleaned, the ground is leveled with cement mortar, and then further waterproof treatment;

2. Leakage of upper and lower water pipes: It is necessary to consider planing the tiles for waterproof treatment, if it is a leakage of the sewer pipe, it is also necessary to find the location of the leakage, and then determine part of the planing bricks according to the situation to solve it, do not carry out all the planing bricks.

The problems that need to be paid attention to in indoor waterproofing are:

1. The waterproofing of the kitchen floor should first be swept flat with cement mortar, and then the flexible waterproof material should be brushed, and the waterproof layer of the ground should be brushed three times in order to better achieve the waterproof effect;

2. Try not to destroy the original waterproof layer, in the process of redecorating the ground, the waterproof layer is very easy to be destroyed, if not repaired in time, it is very easy to leak in the future, so it is necessary to pay attention to the protection of the waterproof layer in the decoration process, and the need to repair it in time if it is accidentally damaged;

3. The base layer of the waterproof layer of the coating should be firm, the base surface should be dry, clean and smooth, and there should be no hollowing, loosening, sanding, dampness and peeling, and the yin and yang corners of the base should be made into an arc.

Cracking of the waterproofing layer indicates that there is a risk of water leakage. It is recommended to re-do the waterproofing.

It is best to explain the family phenomenon of cracking of the waterproof layer in the bathroom, so that everyone can suggest. Otherwise, everyone is completely imagining and guessing the cracking situation out of thin air, and then relying on this suggestion is not very practical and easy to mislead you.

How do you know if the crack is cracked, whether the surface layer is done or not, you must redo the waterproofing, remove the cracked waterproof layer, re-1:3 cement mortar encryption agent compacting and smoothing, and redo the waterproofing, which is generally two-component now.

If the bricks are pasted, remove all the stickers, and then do waterproofing from the new (bathing the piece, make a waterproof one meter wide and one meter high, and you can also do all the walls), and the other three walls can only be made 30 cm from the ground.

This waterproof person is not good at it, and people with poor technology will still leak if they do it, especially where there is a pipe, if they don't do it well, it is especially easy to leak!

Before our company did not use waterproof cloth, directly find Longma to do waterproofing, method: first clean the ground, use cement to leak the place well, and after drying, use a white glue (I forgot the specific) mixed with cement to adjust the brush twice in proportion! The first time I dried, I brushed it a second time!

There are generally 2 layers of waterproof layer for home decoration, one is polypropylene and the other is cement mixed with a waterproof material and attached to the bathroom. The polypropylene layer is generally not easy to damage, if you don't find a drip problem downstairs, it shouldn't be a big problem! However, you'd better do a closed water test

Find a home improvement company or a personal renovation team to sew the whole beauty and then do a leak test.
