The waterproof height of the bathroom wall should be determined according to the specific design of the bathroom decoration. To have a comfortable home environment, you have to do a good job of waterproofing the bathroom wall. So how much is the waterproof height of the bathroom wall suitable, what are the commonly used bathroom wall waterproof material?
Bathroom wall waterproof height
The height of the bathroom wall is waterproof. The national standard specified by the State Construction Commission is 1.8 meters. The building has been waterproofed when it is built. The waterproof layer extends from the ground to the wall and is 250 mm above the ground. However, the waterproofing of the wall surface is basically not available. The height of the waterproof layer of the bathroom wall by the conventional bathroom shower head should not be lower than 1800 MM, and the general thickness should not be less than 1.5 MM, and a 24-hour storage experiment must be done after the waterproofing project is completed.
Bathroom wall waterproof material
The selection of bathroom wall waterproofing materials cannot be overlooked. The place of ordinary residential bathrooms is narrow, and there are pipelines and floor boards, etc. Therefore, the paint is often used for waterproofing and rarely used for waterproofing. There are two kinds of waterproof material for bathroom wall, and there are two kinds of coating waterproof: synthetic polymer---polyurethane waterproof coating (polyester cloth, fiberglass cloth, etc. for corner, etc.); polymer modified asphalt--- SBS waterproof coating (need to add carcass reinforcement material polyester cloth, fiberglass cloth, etc.); asphalt-based waterproof coating is basically not used.
Toilet wall waterproof precautions
There are many places that need attention when waterproofing the bathroom wall. For example, you must not damage the original waterproof layer during the hydropower reform; you must not apply waterproof material on rainy days, and the waterproof coating must be painted three times; After the bathroom wall is waterproofed, waterproof testing must be done.
Concluding remarks: Regarding the waterproof height of the bathroom wall and the selection of waterproof material for the bathroom wall, it is shared here. With regard to the precautions for waterproofing the bathroom wall, I hope that everyone should pay attention to it, especially the last step, testing, must not be sloppy.
How do family bathroom waterproof materials do?
There are a lot of waterproof coatings, such as 'two-component polymer waterproof coating' and 'one-component polyurethane waterproof coating' ... name professional, and there are many types, if according to the nature, currently on the market for sale There are only 5 types of indoor waterproof coatings used, and they have different performances and advantages and disadvantages.
Hard mortar: After the brushing, no need to process the coating, it can be directly tiled and the construction is convenient. Mostly used for the top surface of the back surface of the hard mortar, also known as rigid mortar: emulsion and mortar ratio of 1: 4 after brushing the coating without treatment, can be directly tile, more convenient. After solidification, it forms a cement block, which does not cause water seepage. Its back surface has good waterproof effect and is its biggest advantage. The disadvantage is that this kind of mortar has high hardness and is easy to crack with the deformation of the base layer, so it is generally used for waterproofing the back surface.
Flexible mortar will not affect the waterproof effect even if the base layer is deformed and cracked. It is mostly used for water surfaces such as walls and floors.
Flexible mortar: The ratio of emulsion to mortar is 5: 4 and it has elasticity. Even if the base layer deforms and cracks, it will not affect the waterproof effect. It is mostly used on the surface of water, such as wall surface and ground surface, but it cannot be used on the back surface of the top surface. If waterproof is not done well, there is water penetration and it is easy to make water seepage. Price: 300-500 yuan / barrel, a bucket of 18 kg. There is also a type of silicone-based waterproof coating in flexible mortar, which belongs to high-grade flexible mortar. The elastic tension and flexibility are good, but the price is 600 yuan/barrel, which is relatively expensive and very rare on the market.
Acrylates: Pure liquids, ready to use. Water-based, can be melted in water, it is easy to combine with the gap in the ground to form a strong waterproof layer, waterproof effect is better than flexible mortar. After brushing, it is necessary to perform surface treatment such as pulling or sanding to increase the friction and make it easier to tiling. Due to its excellent waterproofing effect, flexible mortars and acrylates are more suitable for long-term flooding. Price: 300-500 yuan / barrel, a bucket of 18 kg.
Silanes: Pure liquids, ready-to-use, non-aqueous, highly permeable. Unlike other products, which are waterproof on the surface of the base layer, they can penetrate into the base layer to form a 10-30mm strong waterproof layer, and have very good air permeability to ensure that moisture is fully emitted. The construction is very convenient, the labor intensity is low, and can be sprayed directly with a low-pressure spray can, and spraying is completed in a few minutes. The price is not high, 2 liters can do 3-5 squares twice. At present, as a new product, it is best to use Boles.
One-component polyurethane: Both indoor and outdoor use, the brush is very thick, about 3 mm or so, and the elastic tension is more than 300%. It is very elastic. The cracking of any substrate will not cause it to crack. The waterproof effect is the best. Although the safety performance control is among the environmental protection requirements, the odor of such a waterproof coating is relatively large, and it is difficult for most people to accept, and the environmental performance of a few brands is not up to the standard. Polyurethanes are colloidal and are very thick. The use of scrapers during construction is laborious and complicated. After brushing the paint, it is necessary to perform surface treatment, pull the hair or lift sand to increase the friction, and easy to tiling. Price: 500 yuan per barrel, 18 kg per barrel.
The drying speed of these paints is affected by the climate, and the drying speed is slower in a cool climate, but the climate has no effect on the waterproof effect. In general, the mortar drying cycle is 24 hours, and the acrylic and polyurethane drying cycles are 24-48 hours.
'One-component', 'two-component' differences: mortars are two-component polymers, that is, by the emulsion and mortar ratio; acrylic and polyurethane without mortar ratio, is a single component.
Bathroom waterproof practices
1, brush the first time waterproof paint. Before construction, ensure that the construction site is clean and dry. The waterproof coating should be applied completely, with no omissions. It must be firmly bonded to the grass roots, free from cracks, bubbles, and shedding. The brushing height is the same and the thickness must meet the product requirements.
2, brush the second time waterproof coating. Note that there is a certain time interval between the first and second pass of the waterproof coating. After the first pass of the coating, the second pass can be performed. The specific time depends on the coating. The interval is too short and the effect of waterproofing will be greatly reduced.
3, shop protection layer. In order to prevent the subsequent construction from damaging the waterproof layer, a protective layer should be applied on the surface of the waterproof coating. The protective layer must completely cover the waterproof layer without any omission. It has a firm bond with the grass roots, no cracks, no bubbles and no shedding.
4, closed water test. In the closed water test, the water at the highest point on the ground must not be less than 2 cm, and it should be stored for at least 24 hours. It should be considered as qualified after observing no leakage. If there is leakage, you need to redo it, and you must not neglect it.
Primary treatment, cleaning, do leveling layer, bonding layer, additional layers, acrylic waterproof layer, water storage test, protective layer construction, secondary storage test.
1. Correctly check the elevation of the kitchen and toilet, and pay special attention to the correct position of the floor drain.
2. The quality of the wall leaks on the floor drains and pipelines should be carefully inspected. The wall holes should be densely packed and the roots of the pipelines must be required for caulking.
3, Yin Yang angle should be made into a circular arc, and straight, flat light.
4, leveling layer construction: base surface voids, cracks, inequality defects, repair and smooth with cement mortar. The base must be sturdy, smooth and clean, free of dust, grease, wax, mold release agents, and other debris.
5. After the leveling layer is dry, it can be used for waterproof layer construction. The construction period should be fireproof and waterproof. Construction workers should wear soft-soled shoes.
6, after the completion of the waterproof layer, to protect the finished product, no businessmen can move. After passing the inspection and passing the inspection, the company can apply for the concealed project acceptance visa before proceeding with the next process.
7. After the water-proof construction is completed, a water storage test is conducted, and no leakage after 24 hours is considered as qualified. After the installation of the equipment is completed, a secondary impoundment test is performed.
