How to combine the waterproofing of the bathroom made by real estate and the waterproof layer made b

Under normal circumstances, the waterproofing of the bathroom made by the developer is now made with polyurethane waterproof coating, so before re-doing the waterproofing, it is necessary to remove the original polyurethane, expose the cement-based surface, and then use the kitchen and bathroom waterproof slurry to re-do the waterproofing, so as to ensure the best waterproof effect.

The following is the detailed construction method of kitchen and bathroom waterproof slurry:

1.Clean the base surface and sprinkle it with water to moisten but there should be no stagnant water.

2.Prepare the quick-setting repair mortar, add water to the quick-setting repair mortar according to the ratio of 3:1, and the adjusted mortar needs to be used up within 5 minutes. The quick-setting repair mortar is evenly brushed on the yin and yang corners, pipes, sanitary ware, floor drain periphery and other parts that are prone to water seepage.

3.Pour the waterproof liquid and powder into the bucket, then stir evenly with an electric rod, let stand for 3 minutes and stir again for later use.

4.Paint waterproof coating, the bathroom floor needs to be done, the wall needs to be painted at least to the meter, it is recommended to do the full height. Brush 2-3 times, the total thickness is in.

5.After the waterproof coating is dry, it is recommended to make a protective layer of mortar in order to ensure strength.

After the hour, sprinkle water for maintenance, and the part exposed to direct sunlight needs to be covered.

When you pick up the room, it should be a clear water room, and you can do it directly on the original basis

Under normal circumstances, in order to save costs, developers do black polyurethane waterproofing, and when they renovate and carry out hydropower transformation, the waterproof layer has basically been destroyed, and the waterproof effect and environmental protection of polyurethane itself are not good enough, so it is recommended to remove them all, expose the cement base surface, and then use kitchen and bathroom waterproof slurry to do waterproofing.

At the same time, the requirements of the waterproof standard are that the ground needs to be done all, and the wall must be at least full high, and if it is a lightweight wall, then it must be done full height.

You can try the permeable waterproofing.

Dig the best permeable waterproofing can be done by yourself.

If the cement surface is to be waterproofed, use the super permeable waterproof guard of the black gold steel to do waterproofing (if it is incomplete, use the dug beautiful butadia glue to fill the complete and then do the waterproofing).

For the tile surface, first check whether the filling of the tile gap is complete (if it is incomplete, fill it with dug beautiful butadia glue, and then use the black gold steel stone tile type to do waterproofing).

The waterproof layer made by real estate is made of yin and yang corners, or only a thin layer of waterproofing, and it is recommended to make another layer of waterproofing layer by yourself. Whether a house is well decorated or not depends on whether there is any water leakage.

It is recommended that you use Qinglong HG203 waterproof material or JS composite waterproof material.

When receiving the room, it should be a clear water room, and you can do it directly on the original waterproof layer.
