How to make the sink waterproof so as not to leak?

A particularly important process in bathroom decoration is the waterproofing of the bathroom. Personally, any friend is worried about the waterproof problem in the bathroom. After renovation, there will be water leakage in the bathroom, which will be very troublesome to deal with, so be extra careful. So how can we ensure that the bathroom is waterproof and watertight? Here, we really need to pay attention to several issues. In this article, the household miscellaneous altar will share with you the related problems of bathroom waterproofing.

What is waterproof in the bathroom?

The waterproof of the bathroom is actually to use some materials with sealing function to prevent water from infiltrating into the ground or wall. The water in the bathroom seeps into the wall, and the top of each floor will leak, or the wall of the house will leak.

In fact, we should not only pay attention to the waterproofing of my bathroom, but also pay attention to good drainage. Because all the water should be combined with drainage prevention, it can be done well. Waterproofing means sealing the wall and the ground with some corresponding waterproof materials mentioned above. Drainage means using some relevant drainage positions on the ground, such as floor drain, and then finding slopes on the ground to ensure that there is no water on the ground and the water can flow away quickly at any time.

What are the waterproof materials in the bathroom?

The first is polyurethane waterproof coating. Polyurethane waterproof coating is widely used in engineering, because its waterproof performance is actually quite good. Polyurethane waterproof coating is a one-component waterproof coating, which is polymerized from isocyanate and polyether, and processed with catalyst, additives and fillers. This waterproof coating is a cured coating with high strength, high elongation and good weather resistance. But because it has a certain smell, the environmental protection is not particularly good.

The second kind should be SBS modified asphalt waterproof coating. SBS modified asphalt waterproof coating is also widely used in engineering, but it is rarely used in home decoration. SBS modified asphalt waterproof coating is a modified asphalt waterproof coating based on petroleum asphalt, SBS as modifier, and some auxiliary materials. SBS modified asphalt waterproof coating has good waterproof performance, good flexibility and high elongation, especially convenient construction and strong adaptability to the environment. But it also has a certain degree of pollution, that is, it smells, so it is rarely used in the family.

The third is polymer cement-based waterproof coating. Polymer cement-based waterproof coating may be the most widely used waterproof coating in the family at present. The most important component of polymer cement-based waterproof coating is actually the polymerization of cement, polymer latex (commonly known as rubber powder), quartz sand filler (commonly used medium sand), and related additives, defoamers, anti-settling agents and so on. The remarkable characteristics of polymer cement-based waterproof coatings are stupidity, breathability, impermeability, flexibility, weather resistance and convenient construction. Moreover, it has no smell and the highest environmental protection.

How to choose waterproof coating for family health room?

First, it is estimated that everyone cares about environmental protection. Because waterproof materials have good waterproof performance, if they are not environmentally friendly, it is estimated that no one will use them at home. It is estimated that no one can accept an environmentally friendly waterproof material. Think about it, if the bathroom smells pungent every day, how can this bathroom be used?

The second point is the waterproof performance and construction characteristics of waterproof materials. As far as waterproof performance is concerned, the three waterproof materials mentioned above, namely polyurethane waterproof coating, SBS modified asphalt waterproof coating and polymer cement-based waterproof coating, are basically the same, and the construction is also very convenient, so from this point of view, all three are applicable.

Comprehensive discussion, and finally through the introduction and sharing of the above two points, we can actually find that polymer cement-based waterproof coating is the most suitable waterproof coating for bathroom rooms in home decoration. That is, our common polymer waterproof mortar, that is, this waterproof coating.

How to construct waterproof toilet?

The first step should be the treatment of walls and floors. Before waterproofing, we must treat the walls and floors. The ground includes leveling the ground and repairing the honeycomb pit; Walls, including chiseling out some bumps and blocking holes. Simply put, it is a simple leveling seal between the wall and the ground.

The second step is to strengthen the waterproof treatment of some key parts. Here mainly refers to the junction between the wall and the ground of our bathroom, that is, the corner; Flue root; The root of the pipe. These parts must be coated with waterproof paint at least three times in advance to ensure that obvious coatings can be seen after brushing.

The third step is to coat a large area with waterproof paint. This includes the application of our waterproof coating on the ground and the application of waterproof coating on the wall. The wall mainly refers to two parts. The first part is the shower area, which is brushed up by 2000mm；; The second part is the washbasin area, and the brush is 1500mm upward. My personal advice to everyone is to apply waterproof paint on a large area at least three times. Similarly, it can be clearly seen that the thickness of waterproof paint film is qualified.

What are the specific requirements for the closed water experiment in the bathroom?

Toilet closed water test, if from the whole decoration process, you need to do two closed water tests. The first closed water test is after waterproofing is completed, and then the first closed water test is carried out after the waterproof material reaches strength. The second water closing experiment is about a week after the wall tiles and floor tiles in our bathroom are pasted, and the second water closing experiment can be carried out.

The closed water test can be carried out as follows:

Just put a few centimeters of water on the bathroom floor, and then we will observe whether there is any water leakage on the floor below the bathroom and whether there are any traces of water leakage on the other side of the surrounding wall, so as to judge whether there is any water leakage. The requirement of closed water test is not less than 48 hours. Personally, I suggest you make it longer, 72 hours is safer.

How to test the water after the bathroom is tiled?

After the bathroom is tiled, the water test should include two parts:

The content of the first part is the toilet closed water test, also known as the toilet closed water test. The second part of the content should be to test the water in the bathroom, to detect the water accumulation in the bathroom pipeline and the ground, also known as the bathroom test.

Therefore, the test of water after the bathroom is tiled should be divided into two parts. These two parts have different functions and different detection methods. Be sure to distinguish the biggest point.

How to test the waterproof effect after laying the bathroom floor tiles?

After the bathroom tiles are laid, be sure to test the waterproof effect. There is a key test method here, that is, the second closed water experiment in the bathroom. As I told you above, we should do two closed water tests. The first is the first closed water test after the waterproof coating construction is completed and the material reaches the corresponding strength. The second closed water experiment is to do a closed water experiment after the tiles on the floor and wall of our bathroom are laid.

The first water closing experiment after the construction of waterproof paint in toilet is basically about seven days after the waterproof paint is brushed. The specific steps of the closed water experiment are as follows:

The first step is to block all the parts that may cause the water to flow away, including pipes and doorways. The second step is to fill the toilet with water, the depth of which is about 30mm to 50 mm. The third step is to wait for 72 hours, of course, the rule is 48 hours, and then observe whether there are any signs of water leakage. We should not only go downstairs to check for signs of water leakage, but also look at the other wall of our bathroom.

How to do the closed water test after the bathroom wall is tiled?

After laying ceramic tiles in the bathroom, be sure to do a closed water test. This closed water experiment is the last step to test the waterproof effect of our bathroom decoration. Because once the water leakage can be found, generally speaking, when you go to the decoration company at this time, they will definitely bear the responsibility; Don't do this closed water test, find water leakage after delivery, and then find a decoration company. Generally you won't admit it, and there will be disputes in the future.

The concrete method of closed water test after floor tile laying;

The first step is to seal all the drainage pipes in the bathroom with plastic bags filled with sand, so that there can be no leakage. Step 2, block the sand with plastic bags at the door, the height is about 100 mm, and step 3, fill the toilet with water. Generally speaking, the water filling height of the bathroom is about 40 mm After putting the water in the bathroom, you must make a sign on the wall.

The inspection standards are as follows:

First, we also went to the roof downstairs to see if there was any water leakage. The second is to see if there is moisture regain and seepage on the other side of our bathroom wall. The third point is to see the water level in our bathroom drop. Because everyone said above, you must make a sign after releasing water. Generally speaking, after 72 hours, the volatilization of the normal liquid level will not exceed 2.3 mm. If the liquid level drops significantly, it means that there is still water seepage, which needs careful inspection.

How to do water experiment after laying floor tiles in the bathroom?

As mentioned above, the water test has two purposes:

The first thing is to check whether our sewer pipe is blocked. Because in the process of decoration, it is difficult to avoid some sundries entering the drainage pipeline. The second purpose is to check whether the slope of our ground is qualified, that is, whether there is water on the ground.

Specific steps of water experiment:

The first step is to fill the bucket with water, and then fill the floor drain of our house and the sewer pipe of the toilet separately to see if the water can flow away quickly. If the water flow is slow or the water can't slip out, it means that the sewer pipe is blocked and needs maintenance. The second step is to drain water directly on the ground, and then observe the water flow on the ground after stopping for a period of time. See if there is local water accumulation, or whether the water can flow away smoothly through the floor drain, so as to judge whether the slope of our ground is qualified.
