What materials are good for home decoration bathroom waterproofing? How to ensure that there is no w

Good materials for home decoration bathroom waterproofing: polycarbonate, polyurethane waterproof materials have good adhesion to the wall, good follow-up to the wall after wiping, and the area that should be waterproof such as toilets and kitchens is originally a humid environment, if the viscosity is not very good, it is easy to have gaps and eventually leakage. The coating of polyurethane waterproof materials is resolute, high compressive strength, good plasticity, corrosion resistance, strong resistance to structural expansion joint deformation, no cracks and non-fluidity under strict standards, aging resistance, wear resistance, and has a long service life, but it has a smell, black and gray is not environmentally friendly, and it is ugly.

Construction can ensure that there is no leakage: before the waterproof project, the bottom layer must be cleaned, not only can not leave any dirt on the datum, but also the dust must be removed, the neater the bottom layer is removed, the better the adhesion of the waterproof coating. Toilet method engineering construction is at least twice, and have to wait for the wall to paint the architectural paint can be done again after the brush, when brushing must remember to brush along the same direction, the most important thing is not to miss the brush, especially the edge of the area, you have to use the brush to brush carefully in time, the relative height of the wall waterproof coating construction must be noted, the shower area needs to be brushed out of the meter.

After the construction of the waterproof project in the bathroom, there is also the most important step is the irrigation test, the irrigation test is to check whether the waterproof project is up to standard, the most important step to detect whether there is water leakage, the toilet water storage is full of 24 hours, if there is no water leakage reflected under the floor, it proves that the waterproof project is in line with the requirements, and the next step of construction can be carried out.

Generally, after the ground is waterproof and dry, the irrigation test can be carried out. Generally, the irrigation test should not be less than 24 hours, and sometimes the key to water leakage is one to two days, so it is best to do a 48 to 72 hour irrigation test in the bathroom where water leakage is most likely to occur. And after the test, be sure to check the downstairs to see if there is any water seepage problem.

In addition, if it is a sunken bathroom, we must pay attention to the moisture-proof before backfilling, which is much more critical than the waterproofing of the ground.

It depends on the technical construction of workers to ensure that there is no leakage, and we must not cut corners.

The waterproofing of the bathroom should be made of good waterproof materials, and it should be waterproofed several times. In the case of the first dry, do the second waterproofing.

In the process of bathroom decoration at home, try to choose double-layer waterproof materials, and you should choose waterproof with better performance. In the process of construction, a more careful construction team should be selected.

Bathroom decoration is very troublesome, and it is necessary to make waterproof walls to avoid water seepage on the wall in the later stage. The practice of waterproofing construction in the bathroom is as follows:

1. When the bathroom is waterproofed, the waterproof of the ground needs to be treated. Use cement mortar to level the uneven part of the ground, and then do waterproofing, so as to avoid the uneven thickness of the waterproof coating in the later stage, or the situation of missing brush, resulting in leakage.

2. Paint waterproof materials. When painting waterproofing materials, there should be no omissions, especially the joints, the water pipes, and the connection between the floor and the wall.

3. Wall treatment. The light wall of the bathroom, when doing waterproofing, needs to be painted with waterproof paint on the entire wall. If the bathroom has a design bathtub, the waterproofing of the wall around the bathtub needs to be above the bathtub.

4. Waterproof test. When the waterproof construction of the bathroom is treated, the drain of the toilet needs to be blocked, and then the toilet is filled with water to make it at a high level, and then wait for 24 hours to see if there will be a significant drop in water level.

5. Keep the drain in the toilet smooth. When the bathroom waterproofing test is completed and there is no problem, you can remove the items that block the sewer pipe and keep it smooth.

Bathroom decoration is very troublesome, what should I do to waterproof the bathroom? Is it necessary to make the wall waterproof? The wall of the toilet should be waterproof, because the country has strict waterproof requirements for construction and decoration, and not waterproof will not only cause the bathroom to leak, but also affect the use of the wall of other families.

When waterproofing toilets, they must be carefully treated to avoid leakage of cracks in the middle. Since water often flows out of the bathroom when we take a bath, mud seeps into the walls, and if the walls are not waterproofed, it often causes friction, so it is necessary to do waterproofing.

To waterproof the floor, the first thing to do is to level the ground, then the wall is waterproofed, the floor is leveled with concrete, and then the waterproofing treatment is carried out. This prevents opacity due to inconsistent thicknesses. The soil layer is an isolated water layer, and it is difficult for moisture to penetrate into the wall when the soil intersects.

The most problematic area is the connection point between the bathroom wall and the sewer and floor. Be sure to urge employees to dispose of these corners during work, so be sure to apply waterproof paint.

In terms of ordinary waterproofing of the bathroom, a waterproof coating of about 30 cm should be added to the wall, and waterproof measures should be taken on the toilet wall to prevent water from flowing through the wall. However, if the bathroom wall is a light wall that is not load-bearing, then all walls must be covered with waterproof paint. If you use two sprinkler heads, you will have to paint the two associated walls.

If a bathtub is used, the relative height of the impermeable coating is 30 cm above the upper edge of the tub. Special waterproofing and plugging measures should be adopted for drains and sunny angle lines.

After the toilet work is completed, there should be all the drainage holes in the toilet wall that are waterproof, and a sink "can" 25 cm should be built before the shower, and then filled with a pool of about 20 cm. After 24 hours, check the surrounding walls and wood materials for leaks. This 24-hour uninterrupted waterproof inspection is of great significance to ensure the construction of the bathroom waterproof project.

Toilets are prone to leakage, causing cracks in plastic cement; Do a good job of waterproofing, post-treatment will damage the waterproofing (veneer brick); The use of inferior waterproof raw materials (low prices and no good goods); Failure to waterproof in accordance with the regulations or insufficient thickness (greater than mm); Contacts are not treated in accordance with regulations (not handled well); The construction seam penetrates the pipeline, destroying the original waterproof layer and causing leakage; When doing waterproofing, the substrate can not meet the needs of the design, and there are sand, relaxation, etc.; The inconsistency of the shrinkage of the water pipe and the cement creates cracks.

When the bathroom is decorated, first of all, you need to clean the ground and wall, and there can be no dust, gravel and cement, and then do a leveling and slope, if the ground and wall have cracks or hollow drums, re-smooth with cement mortar to ensure that it is firm and smooth. At the same time, the yin and yang corners of the bathroom need to be made into arcs, and these places are the focus of waterproofing. The bathroom wall should be waterproof, because the water consumption in the bathroom area is very large, and the shower water will splash on the wall, if it is not waterproof, the wall will seep and leak;

If you want to do a good job of waterproofing the bathroom, the key lies in the selection of materials, and you must choose a more formal construction team, and there is no need to do waterproofing for the wall.

After the waterproof construction is completed, the 48-hour closed water test must be done. The walls need to be waterproofed.

polyurethane materials; Polyurethane waterproof coating has good viscosity to the wall, and has strong follow-up to the wall after wiping, and the area that should be waterproof in the toilet and restaurant kitchen is originally a humid environment, if the viscosity is not very good, it is very easy to produce cracks and eventually seepage. Polyurethane waterproof coating has perseverance, high tensile strength, good ductility, strong corrosion resistance, strong structural expansion deformation ability, no cracks and no flow under strict standards, anti-aging, wear resistance, and has a long service life, but it has a smell, gray and black is not environmentally friendly, and it is not good-looking.

acrylics; It is a water-soluble, colorable, plastic-type architectural coating made of acrylic resin copolymer moisturizing emulsion as gelatinizing chemicals and various color pastes and fillers. It is characterized by the fact that the coating can produce a continuous coating after drying, and the coating has excellent tensile strength and elongation at break, acid resistance, good acid resistance, excellent aging resistance, and no air pollution, which is an ideal raw material for roof waterproofing applications. At the same time, the construction of the project is convenient, and the construction of roller coating and brushing can be carried out.

The ground waterproofing produces a continuous elastic membrane for the contacts, which is convenient for the cumbersome structure. Because its functional characteristics are relatively stable, the application effect is ideal, and the price is moderate, it is widely used in home decoration waterproofing. It is used in large-scale projects.

polymer cement; Polymer cement waterproof coating (referred to as JS waterproof material) is a combination of rigidity and flexibility component waterproof coating. This kind of raw material environmental protection, non-toxic and odorless, good air permeability, strong adhesion with the ground, dry quickly, not only has the high-quality elasticity of polymer material chemicals, but also has the two-way advantage of good durability of inorganic materials. However, it is mostly a component of raw materials, and it is necessary to prepare liquid materials and granular materials according to the specific guidance of the instructions for use, and if too much light calcium powder is added to the granular materials, the material performance is usually greatly reduced.

It is mainly used in home decoration.

concrete mortar; Concrete mortar waterproof coating is an organic chemical moisturizing emulsion material composed of acrylic emulsion and a variety of filling additives, with organic particles composed of special cement and various fillers, and a certain proportion of the component water-soluble waterproof mortar. This kind of architectural coating is non-toxic and harmless, zero pollution, is a real green architectural coating, it can be immediately built on the surface of the cement and bonded firmly, convenient engineering construction, will not be limited by the water content of the bottom layer, dry quickly, short coagulation time, after engineering construction 2 can be pasted on the surface of the floor tiles. However, in view of the fact that this kind of raw material belongs to the flexible waterproof architectural coating, which lacks elasticity after coating the film, and will endanger the actual effect of moisture-proof due to the sinking and displacement of the engineering building, it is generally suitable for a relatively stable position of the structure.

You can choose polyurethane waterproof coating, this waterproof coating is relatively common, the use effect is very good, especially environmentally friendly.

When decorating the bathroom, try to choose a better waterproof material, and the waterproof thickness of the bathroom should be at least about 50 cm. Try to do double waterproofing.

In the decoration of the bathroom, there is a particularly important process that is the waterproofing of the bathroom. Personally, any friend is concerned about the poor waterproofing of the bathroom. The toilet leaks after the renovation and is a hassle to deal with, so be extra careful.

Waterproofing in the bathroom is actually the use of some materials that have a sealing function to prevent water from seeping into the floor or walls. When water seeps into the walls from the toilet, the roof of every floor leaks, or the walls of your own home leak and seep water. In fact, we should not only pay attention to the waterproofing of the bathroom, but also pay attention to good drainage.

Waterproofing combined with drainage. Waterproofing refers to the use of some corresponding waterproof materials to seal the walls and ground, and drainage refers to the use of some relevant drainage locations on the ground, such as floor drains, and then to ensure that there is no water on the ground through the ground slope, and the water can flow out quickly at any time.

How to build a waterproof restroom? The first step should be to deal with the walls and floors. Before waterproofing, we have to deal with the walls and floors first.

Flooring includes leveling the ground and repairing the honeycomb surface; walls, including chiseling out some protrusions and plugging potholes. Put simply, this means simply leveling and sealing walls and floors. The second step is to strengthen the waterproofing treatment of some key parts.

This mainly refers to the junction between the wall and the floor in our bathroom, that is, the corner; flue roots; The root of the tube. These areas must be coated with waterproof paint at least three times in advance to ensure that a visible coating is visible after brushing. The third step is to brush a large area of waterproof paint.

This includes brushing our floors with waterproofing paint and brushing the walls with waterproofing paint. A wall mainly refers to the two parts of a wall. The first part is the shower area, sprayed upwards by 2000 mm; The second part is the washbasin area, which is sprayed upwards by 1500 mm.

My personal recommendation is to brush a large area of waterproof paint at least three times. Again, it can be seen that the thickness of the waterproof coating film is qualified. After laying the tiles in the bathroom, we have to carry out a closed water test.

This closed water experiment is the final step in testing the waterproofing effect of our bathroom décor.

1. The first step is to ensure that the ground is dry, and it is not recommended to brush waterproof on rainy days or just after rain. 2. In order to ensure the fullness before painting, it is necessary to do cement mortar leveling on the ground first, if the leveling is not done, it will lead to uneven thickness of some waterproof coatings after brushing, and some protruding places may pierce the waterproof material, and finally it will leak. 3. Pay attention to two details during the painting process, one is to brush the joints such as floor drains, drains, etc., and the other is to paint the whole wall of the shower area.

Do a good job of waterproof treatment, do a good job of leak-proof treatment, use waterproof materials, use moisture-proof materials, and choose experienced workers; Choose a professional team, choose experienced workers, choose moisture-proof materials, choose waterproof materials, and follow the advice of workers.
