Bathroom floor waterproof material toilet waterproof construction practices

Most of the bathroom leaks are caused by bathroom floor waterproofing materials. There are many unqualified materials on the market. For those who are not well-versed in fitting, it is easy to purchase inferior bathroom waterproof materials. At present, there are two types of toilet waterproof materials on the market, one is polyurethane waterproof coating; the other is polymer cement-based waterproof coating. Then, Xiaobian will introduce bathroom floor waterproof materials and toilet waterproof construction practices.

Bathroom floor waterproof material

1, asphalt waterproof material. The natural asphalt, petroleum asphalt and coal asphalt as the main raw materials, made of asphalt linoleum, asphalt tire felt, solvent-based and water emulsion bitumen or asphalt rubber coatings, ointments, with good adhesion, plasticity, Water resistance, corrosion resistance and durability.

2, rubber plastic waterproof material. With neoprene rubber, butyl rubber, ethylene propylene diene monomer, polyvinyl chloride, polyisobutylene and polyurethane as raw materials, it can be made into elastic tireless waterproof membrane, waterproof film, waterproof coating, coating material and ointment, cement Sealing materials, such as sealing tapes, have high tensile strength, high elasticity and elongation, good adhesion, water resistance, and weather resistance. They can be used coldly and have a long service life.

3, cement waterproof material. Admixtures with a coagulative effect on cement, such as water repellents, air entrainers, and expansive agents, can increase the hydrophobicity and impermeability of cement mortars and concrete; and promote coagulation with cement and sodium silicate as base materials. Mortar, can be used for underground engineering plugging and waterproofing.

Toilet waterproof construction practices

1, ground treatment

Before the waterproof treatment, be sure to level the ground first. If the ground is uneven or the effect is not good, it may cause cracking and leakage due to uneven thickness of the waterproof coating. Floor drains, wall corners, pipes and other joints should be made of highly flexible, flexible, water-proof paint, because the joint between the wall and the floor of the toilet will shift to the point of seepage.

2, wall treatment

On the wall surface treatment, about 750px high waterproof paint should be applied to prevent water from seeping into the wall. If the bathroom has a shower room, the waterproof should be 4500px. If there is a bathtub, the height of the wall adjacent to the bathtub should be higher than the bathtub. 750px high.

3, after the waterproof layer to do a good job to stay more than a certain period of time, so that the waterproof layer and the building better integrate, and then do a protective layer on the waterproof layer in the paving tiles, the construction process, can be sloppy. Protect the waterproof layer as much as possible.

4, waterproof is a hidden project, the follow-up construction may also damage the waterproof layer, if the floor tile has been laid, you can not smash the floor tiles, with professional repair sewing waterproof material, all the gaps to make a good waterproof . The same applies to the waterproof construction after the toilet waterproof layer fails.

5. Waterproofing is a systematic project. The causes and treatment methods are not the same in every place. Materials are the foundation, construction is the key, and follow-up services are guaranteed.

Bathroom floor waterproof material selection

1, according to the local maximum temperature, the minimum temperature, flexible selection of heat-resistant or low temperature flexible waterproof coating. In high temperature areas, waterproof coatings with high heat resistance should be selected to prevent run-off; in cold regions, low-temperature flexible waterproof coatings should be selected to avoid cold brittleness.

2, according to the degree of deformation of the foundation, the structure of the form, the local temperature difference, the daily temperature difference and the vibration factor, should choose suitable tensile properties of waterproof coating. For architectural roofs with large structural deformations, waterproof coatings with high elongation should be selected to accommodate deformations, such as Lei Bangshi's flexible JS waterproof coating.

3, according to the degree of roofing waterproof coating exposure, should choose the UV-resistant, heat aging retention rate compatible with the waterproof coating. For exposed roofs, waterproof UV-resistant coatings should be used to increase the service life.

4. When the roof drainage gradient is greater than 25%, it is not appropriate to use a waterproof coating that takes too long to dry.

Editor's summary: On the bathroom floor waterproof material and bathroom waterproof construction practices introduced here, and hope to be helpful to everyone. If you want to know more about yourself, you can follow the information on this site.
