How to do waterproof plugging in the bathroom? What materials are good?

The bathroom is waterproof and leakage, 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. At present, there are usually two types of home improvement waterproofing materials on the market: one is liquid waterproof coating, polyurethane waterproof coating and polymer composite waterproof coating; The other is powdered waterproof plugging materials, such as waterproof rubber powder and plugging spirit, etc.

The leaking part is chiseled and cleaned, painted with pure cement mortar, and coated with polyurethane waterproof paint with a thickness of 3mm (painted in two times) to make a protective layer of cement mortar.

The leakage part between the branches of the sanitary bird is chiseled and cleaned up in Xiaozhou, painted with pure cement mortar, and painted with polyurethane waterproof paint with a thickness of 3mm (painted in two times) to make a protective layer of cement sensitive mortar.

First, clean the surface of the base layer and keep the surface clean and flat. If it is not leveled, it needs to be leveled with cement mortar. Then use high-quality environmentally friendly materials to paint.

Now there are two major types of waterproof materials on the market: one is polyurethane waterproof coating. These materials are generally made of polyurethane and coal tar.

The tar gas it volatilizes is highly toxic and not easy to remove. The other type is polymer cement-based waterproof coatings. It is composed of an emulsion synthesized from a variety of water-based polymers and a high-quality cement-based protein mixed with various additives, and the flexibility of the polymer (resin) is combined with the rigidity of the cement, which makes it excellent in terms of impermeability and stability.

Its advantages are convenient construction, low comprehensive cost, short construction period, and non-toxic and environmentally friendly. As a result, polymer cementitious bases have become the protagonists of the waterproofing coatings market.
