    Yes. 1. According to the general practice, it should be necessary to go through a 24-hour closed water test, and further construction can be carried out after determining that there is no water leakage.

    3 days will not affect the quality of the waterproofing layer.

    3. There is no clear regulation on the thickness of the waterproof layer, as long as it is prepared according to the method on the construction instructions; In terms of the interval of construction time, the second coat can be painted after the first pass is dry. The direction of the first painting should be carried out in the form of a cross with the direction of the second painting.

    4. The bathroom is waterproof, and the surrounding walls need to ensure that the height of the painting is not less than 30 cm; If there is a shower, the height of the waterproof paint applied on the installation of the shower faucet and the adjacent wall should not be less than 150 cm, preferably about 180 cm.

    After the waterproofing is done, a closed water test should be done. It is to put the water on the floor of the bathroom, so that the ground is completely submerged in water about 3 4 cm, and set a fixed elevation (horizontal plane); After 24 hours, if the water level is below the set elevation, it means that there is a water seepage problem on the ground, that is, the waterproofing is not done well. In this way, it is necessary to re-do the waterproofing.

    After the bathroom waterproof paint is brushed, tiles should be pasted on it, so cement-based waterproof materials should be used to paint. The cement-based waterproofing material can be bonded to the cement base layer, its adhesion is very good, and it will not shell after pasting the tile. Other (non-cementitious) waterproofing materials are prone to shelling, which can cause wall tiles to fall off.

    After the waterproof coating on the ground is confirmed to have no water seepage problem after the closed water test, it is necessary to cover a protective layer with a thickness of about 2 3 cm with cement mortar on it, so that the waterproof layer will not be destroyed by the construction behavior later.

    5. The construction of tap water pipelines should be finished before the waterproof coating is applied, and the surrounding of the pipeline should be covered with cement mortar, and the surface should be as smooth and smooth as possible; Before applying waterproof paint, remove the dust left on the walls and floors.

    Hello landlord.

    The common practice of waterproofing in the general bathroom is:

    If the wall of your shower is directly facing your bedroom or living room, then you must make it waterproof, at least high, if it is only for the exterior wall, you can only make it 30---50 cm high.

    In fact, it is very important for the bathroom to be waterproof.

    Think about it, if you don't make the wall waterproof, the wall connected to your shower will definitely become moldy and even damp in the future.

    If you don't do a certain height of other walls, in case the water leaks below, the residents below may have to come up to you for trouble, more than one thing is better than one less thing, anyway, your bathroom floor should be waterproof, use a little more material, save the trouble in the future!

The bathroom is divided into dry and wet areas, and the dry side is brushed to the meter, so that the moisture will not turn over to the outside wall, and the wet area is sprayed, so it is necessary to brush to the meter to control the outside wall from being affected.
