Which kind of waterproof coating is good for the bathroom? What do I need to pay attention to during

1. Bathroom waterproof construction steps.

Step 1: You can use slightly coarser cement as a primer first, and wait for the cement to dry before brushing the waterproof coating. But in painting money, the ground should be flat and there should be no grooves. Water is then sprinkled on the ground to expel the gas from the small holes.

Step 2: Mix the powder and liquid material evenly, and brush the bubbles if there are bubbles when brushing the paint.

Step 3: When brushing the paint, brush it from the same direction, wait 1-2 hours, and then brush the second coat. When brushing the second layer, the direction of the brush should be opposite to that of the first layer, so that the best coverage can be achieved.

Step 4: You can brush it several times, which can increase the density and fill the gaps. Some people think that the more layers of waterproof paint the better, or even brush six or seven layers, but in fact, this is not good, the paint is too thick and easy to crack.

Step 5: Wait for one day before taking a waterproof test.

Step 6: When doing the waterproof test, you should first fight with your downstairs neighbor.

Say hello, then plug the drain, fill the ground with water, and wait an hour to ask your downstairs neighbor if there is a leak. If there is a water leak, the waterproofing layer should be rebuilt. If the waterproof test is qualified, it can be tiled.

2. Precautions for waterproofing in the bathroom.

1. In order to ensure that the bathroom floor is flat, it must be leveled with cement mortar, and then waterproof, so as to avoid leakage caused by uneven thickness of waterproof coating.

2. After leveling, when carrying out the construction of the waterproof layer, it is necessary to pay attention to fire prevention and waterproofing.

3. When doing waterproof construction, the floor drain, pipeline, and wall hole should be carefully inspected, and the root of the pipeline must be caulked according to the requirements during construction. 4. The waterproof treatment of the wall should also be noted, if the wall and the bathtub are adjacent, then the waterproof treatment height should be higher than the upper edge of the bathtub, and the shower should reach a height of 180cm.

5. Before doing waterproofing, pay attention to the correct position of the floor drain elevation.

6. To ensure that the sewer is smooth, the sewer pipes in the bathroom, including floor drains and toilet sewer pipes, must be kept unobstructed.

There are many bathroom waterproof materials on the market, and the effect is not bad, but we should pay attention to the specific details of the bathroom waterproof construction, otherwise even if the best waterproof materials are used, it may not be satisfactory to get the results.

1.Acrylic waterproofing material.

The biggest advantage of acrylic waterproofing materials is that after the coating is applied to form a conjunctiva, the acrylic conjunctiva has super elasticity and ductility, so it is very suitable for toilet waterproofing. And it can be applied on a wet base layer, with high bond strength, and a firm combination with the base layer and the outer protective decorative layer. Completely green and environmentally friendly, no pollution and no peculiar smell.

2.Cement mortar waterproofing material.

Cement mortar waterproof materials need to be matched with cement mortar in a certain proportion to form a uniform mixing liquid. When batching, the liquid material is stirred with a stirrer, and the powder is slowly added in the stirring state for mixing and stirring (an appropriate amount of water can be added to adjust the viscosity, but it is best to add water before adding the powder), and it is necessary to fully stir and disperse to achieve uniformity without powder ball and precipitation. The prepared ingredients should be used up within 2-3 hours.

3.Polymer polymer waterproof material.

Polymer polymer waterproof material is composed of a variety of water-based polymer synthetic emulsion and high-quality cement mixed with various additives, the flexibility of polymer (resin) and the rigidity of cement are integrated, making it excellent in impermeability and stability. Its advantages are convenient construction, low comprehensive cost, short construction period, and non-toxic and environmentally friendly.

The choice of waterproof coating for the bathroom is a very critical step, and if the paint is selected well, it is also very beneficial to your later waterproof work.

The general bathroom leakage water is the details of the building problems, the most prone to problems in three places, we should pay attention to the three places are floor drains, wall corners, pipe roots, these three places due to more interfaces, easy to appear gaps, so easy to leak water. In addition, if the connection between the bathtub drain and the sewer pipe is not tight, it will be easy to create gaps and leakage. Therefore, we should choose a coating that is most suitable for bathroom decoration, and we should choose Langkaiqi flexible-acrylic modified waterproof coating for waterproof coating.

Because this material can tightly wrap the pipe and the ground, penetrate into the gaps, and will not shrink after drying, it is more suitable for small areas of houses with many pipes and gaps such as bathrooms than rigid materials such as waterproof cement. Therefore, customers should choose Longkeqi brand coatings when buying this kind of paint.

After the waterproofing construction is completed, all the sewers in the bathroom should be blocked, and a "low wall" should be built at the door of the bathroom for water injection test, and the water injection height should be about 500px. After 24 hours, if there is no leakage on the walls and floors around the bathroom, it means that the waterproof quality of the bathroom is very good. On the contrary, it is necessary to find out the leakage point and carry out repairs.

At the same time, the wall should also be waterproof. In order to achieve a better waterproof effect, the wall of the general bathroom should also be waterproofed about 750px high to prevent water from penetrating the wall. The wall adjacent to the bathtub should also be waterproofed at a higher height than the top edge of the bathtub.

In this way, nothing is lost.

1. One-component polyurethane waterproof coating.

The waterproof coating is a reactive flexible waterproof coating, which has good physical properties, strong adhesion, and curing at room temperature and humidity.

2. Non-tar polyurethane waterproof coating.

The waterproof coating is a two-component material, using water as the chain extender, which avoids the toxicity of the amine chain extender, and forms a rubber waterproof layer with elasticity and no joints after curing.

3. Acrylic waterproof coating.

The waterproof coating is made of pure acrylate copolymer or pure propionate emulsion, adding an appropriate amount of high-quality fillers and additives, and is a synthetic resin one-component waterproof coating.

4. JS composite waterproof material.

This kind of waterproof coating is a waterproof coating composed of organic liquid material and inorganic powder, which has the advantages of high elasticity of organic materials and good durability of inorganic materials.

Waterproof material. It is a new type of waterproof material developed after absorbing foreign advanced technology.

5. Cement-based permeable crystalline waterproof material.

The waterproof coating is a waterproof material composed of Portland cement, quartz sand, special active chemicals, etc. With the strong permeability of water, chemical reaction and water and leak resistance are realized.

It is best to supervise the construction during construction, and then test whether it is waterproof many times, I hope it will help you!
