1. What material is used for kitchen waterproofing?
1, cement mortar
This is a two-component waterproof mortar, which is made of organic emulsion composed of acrylate emulsion and various additives, and inorganic powder composed of special cement and filler in a certain proportion.
Advantages: Cement mortar is a water-based coating, which is non-toxic and harmless, and has very high environmental protection. But also can be directly coated on the concrete surface, and has the advantages of firm bonding, convenient construction, quick drying and short setting time.
Disadvantages: it is a rigid waterproof coating, which has poor elasticity after film formation, and will affect the waterproof effect with the settlement and dislocation of the building, so it is more suitable for use in the position with stable structure.
2. Polyurethane
Polyurethane waterproof coating has the reputation of "liquid rubber" and its comprehensive performance is very good.
Advantages: tough coating, high tensile strength, good ductility, corrosion resistance, strong structural expansion and deformation resistance and long service life.
Disadvantages: This waterproof material is not recommended for construction on wet foundation, which requires high fire safety.
Second, how to make the kitchen waterproof?
1, the base surface is clean
Before waterproofing, ensure that the base surface is clean and tidy without any dust and garbage, so it can be cleaned with water before construction, as long as the surface is wet and there can be no Mingshui.
2, the ground waterproof slurry coating
Brush special areas in a small area first, such as floor drains, around pipes and corners. Then you can paint on a large scale for the first time. After the brush is soaked, the paint sticks to the brush in one direction, and the thickness of the paint film is within 1mm, which is easy to dry and not easy to bubble and crack. After drying, it can be painted in the cross direction for the second time to avoid brush leakage, and the closed water test can be carried out the next day.
3, wall waterproof slurry coating
The wall should also be waterproof, and the height is about 180cm, which can prevent the faucet from wetting the wall. Its practice is the same as that of floor waterproofing, the only difference is that the waterproof slurry is different, and the special coating for wall surface should be used.
Third, how waterproof is the kitchen?
1, the waterproof of the kitchen is generally applied to about 1.5 meters, because the upper part of the kitchen is used for the treatment of oil fume, and the places where water is used are basically below the height of the sink. It is suggested that the wall waterproof material should also be brushed twice to be more waterproof. Because wall waterproofing is not the focus of kitchen waterproofing, coupled with the characteristics of cement base, you only need to look at it with the naked eye to check whether the waterproofing project is done well. If the cement base is well brushed, its effect must be square.
2. The waterproof work of the kitchen can't be ignored. Although there is not much water output in the kitchen, there are also hidden dangers of pipeline explosion, sewer blockage and kitchen overflow. If there is any mistake in the construction process, there will also be water seepage caused by loose connection near the sink.
Four, the kitchen waterproof matters needing attention
1, when repaving floor tiles, the ground is waterproof.
If the kitchen floor tiles need to be replaced, after the original floor tiles are chiseled, you must first find the square floor with cement mortar, and then waterproof it to avoid leakage caused by uneven thickness of waterproof coating. Be sure to clean the ground before waterproofing and brush polyurethane waterproof coating for 2-3 times.
2. Try not to destroy the original waterproof layer.
If the waterproof layer is damaged, it will cause great inconvenience in the future. If it is not repaired in time, it will leak in the future. Therefore, it is suggested that the waterproof layer must be protected when decorating. If it is damaged carelessly, it should be repaired in time to avoid leaving hidden dangers. If the previous waterproof layer has been damaged, it needs to be redone in time.
3, the water tank on the wall should also be waterproof.
When pipes, floor drains, etc. When crossing the floor, the waterproof layer should be carefully constructed, and the water pipes should be buried in the wall, so that the layout is reasonable. All the laid water pipes should be made into grooves larger than the pipe diameter, and the plastering in the grooves should be smooth, and then polyurethane waterproof coating should be painted in the grooves. The floor of the kitchen must be inclined to the floor drain, and the slope should be appropriately increased. When decorating the kitchen pipes, we should try our best to avoid changing the original drainage pipes and floor drains, so as to avoid re-arranging pipes and roughening the ground to destroy the waterproof layer and cause leakage.
