How to make the bathroom waterproof and what is the construction technology?

At present, there are two kinds of commonly used coatings for bathroom waterproofing:

(1) Synthetic polymer polyurethane waterproof coating (polyester cloth, glass fiber cloth, etc. Need to be used for corners, etc. )

(2) polymer modified asphalt SBS waterproof coating (polyester cloth and glass fiber cloth, etc.). Need to be reinforced with matrix).

Specific specifications for waterproof practices in toilets:

1, waterproof construction should use coated waterproof materials.

2, waterproof material performance should comply with the provisions of the current national standards, and should have the product certificate.

3, base surface should be smooth, can not have empty drum, sand, cracks and other defects. The moisture content of base course should meet the construction requirements of waterproof materials.

4, waterproof layer should extend from the ground to the wall, 250mm above the ground. The height of the waterproof layer on the bathroom wall is not less than1800 mm.

5, waterproof cement mortar screed-coat and foundation combined with dense, no empty drum, smooth surface, no cracks, sand, Yin and Yang Angle into a circular arc.

6, besmear brushs waterproof coating evenly, thickness meet the requirements of product technical regulations, general thickness is not less than 65438+/-0.5 mm is not exposed.

7, the use of summer-planting construction should be along the direction of running water lap, lap width is not less than 100mm, when using more than two layers of glass fiber cloth lap up and down, should be staggered by half of the width.

8. The coating surface shall be free from blistering, flowing and unevenness, and the joint with pipe fittings, sanitary ware, floor drain and drain shall be tight, smooth and without leakage.

9. The thickness and strength of protective layer cement mortar must meet the design requirements. It is forbidden to destroy the waterproof layer during operation. According to the design requirements, do a good job in the flooding slope of the ground, the drainage should be smooth, and there should be no water accumulation.

Toilet waterproof practice height:

1, waterproof decoration height of toilet floor.

Waterproof of the bathroom floor is the most important part of bathroom decoration, so the waterproof height of the floor should be thin. Toilet floor waterproof height, usually we choose pouring reinforced concrete floor pavement, 1: 3 cement mortar to find the slope layer, the thinnest part of the ground should also have a layer of 20mm thick, 30㎜ thick hardened cement mortar combination layer, find the slope to the floor drain, and smooth it at a time.

2. Waterproof decoration height of bathroom wall.

General waterproof wall waterproof height should be 30 cm high. For non-bearing walls, when the whole wall is waterproof, its basic waterproof height should be at least 1.8 m high. The waterproof coating on the wall should have a height of about 30cm to prevent water from infiltrating into the wall to regain moisture. The waterproof height of the bathroom wall with shower room should generally be180 cm; ; There is a bathtub, and the waterproof height of the wall adjacent to the bathtub should be 30cm higher than that of the bathtub.

3. Waterproof decoration height of bathroom floor tiles.

When installing floor tiles, it is an important part of waterproof in our bathroom. When laying floor tiles, in addition to making a waterproof layer under the surface, leveling the ground with cement mortar and coating waterproof coating, the place where the waterproof layer of floor tiles contacts the wall should be surrounded by an upper wall, which is about 25 ~ 30cm higher than the ground. The waterproof height of the toilet sewer is related to our future life and health problems, so when dealing with it, one is to prevent the odor in the drain pipe from overflowing the sewer and entering the room, so as to prevent the sewer from being blocked.

4, toilet washbasin, urinal waterproof decoration height.

The wall of the bathroom in contact with the washbasin is 300mm from the ground to the washbasin; If your toilet is not a toilet but a urinal, then its waterproof height is 1800mm from the ground. The waterproof height of the pipeline (including casing) passing through the floor in the bathroom is about 100mm above the pipe root.
