How many times do you need to brush waterproof paint in the bathroom?

Waterproof coatings can be used to make the bathroom waterproof.

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 paint that is most suitable for bathroom decoration.

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. 24 hours after inspection, if the walls around the bathroom.

And there is no leakage on the ground, which 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. Inspect and accept the appearance, variety, specification, packaging, size and quantity of materials, and form corresponding acceptance records.

2. Check the quality certification documents of the materials and include them in the engineering and technical files.

3. After the material enters the site, the material inspection report shall be issued according to the specification.

4. When all the indicators of the physical properties of the material meet the standards, it is qualified; If an index does not meet the requirements of the standard, the index should be re-sampled in the tested product for re-inspection, and the re-test result meets the requirements of the standard, and the batch of materials will be judged to be qualified.

5. Waterproof material. There are three main categories: waterproofing membranes; 911 polyurethane waterproofing material; New polymer cementitious waterproofing material.

The last category is divided into general-purpose GS waterproofing materials and flexible JS waterproofing materials. Among them, the universal waterproof material is suitable for the waterproofing of the indoor floor and wall of the family.

What is the most important thing about home renovation? It must be the basic decoration of water and electricity, waterproof is a very important part of home decoration, waterproof is not done, they live in the heart, downstairs with trouble. Ask the master how many times the waterproof must be done, and the master said that how many times to do it is not the most important, the important thing is how to do this waterproofing.

1. Clean the walls and floors, and block the bathroom pipes.

Do hygiene before waterproofing, and seal the toilet pipe mouth to prevent debris from falling into the pipe. Sweep off the floating ash on the wall and clean up the floating ash on the ground.

2. The wall and the ground should be leveled, and the water should be discharged at the root of the pipe.

The pipe excavation of the wall should be repaired with cement first, and the ground should also be leveled, and the treated ground should be waterproof at the root of the pipe to ensure that the root of the pipe does not leak.

3. Brush waterproof for the first time.

The waterproof paint must be applied all over the place, without foam and cracks, and the height of the brush should be consistent. Paint the wall first, then the ground, from the inside to the outside, and don't step on the waterproof layer after brushing. Pipe roots, wall cracks, and corners should be smeared emphatically.

4. Brush waterproof for the second time.

The second waterproofing must be brushed after the first waterproofing is dry, otherwise it will not play a role in reinforcement.

5. Waterproof protective layer.

Many masters will ignore this step and directly do a closed water test, and the responsible master will lay a protective layer with cement mud on top of the waterproof layer, which can protect the waterproofing from being damaged by the backfill construction behind.

6. Closed water test.

The closed water test is a must, generally speaking, the water depth of the closed water test must reach more than 24 hours, the water level has not been significantly reduced, and there are no traces of leakage in the downstairs pipeline, so you can judge that the waterproof is qualified.

Now some masters tell the owner to do it three times or five times, in fact, they also want to charge a little more wages, and a good waterproof is enough once. Some masters did not do protection when they did the first waterproofing, for fear that the backfill would damage the foundation waterproofing, and they would do waterproof protection again after the backfill ended the cast-in-place cement.

Hello, it generally takes twice :

1. The first time.

When doing waterproofing for the first time, the waterproof coating is evenly and densely brushed on the base surface, and the coating layer should not be too thick, otherwise it is easy to rise and not easy to dry. Be careful to stir the bottom of the bucket a few times each time you apply to avoid the paint settling. The coating should be uniform, there can be no local deposition, it is recommended to brush several times more times to avoid air bubbles between the paint and the base layer, and the bond is not firm.

The coating must be applied in accordance with the prescribed dosage and must not be too thick or too thin. At the end of the construction, all tools and work clothes stained with paint should be washed with water in a timely manner. Otherwise, it will be difficult to clean the paint after it has dried.

2. The second time.

When waterproofing for the second time, it is recommended to brush horizontally and vertically twice, and also do waterproof tests such as water injection experiments, and inspect in advance. If you don't know much about the inspection, it is best to hire a professional supervisor if you have the conditions, which can save a lot of worry.

Brush 2 times: waterproof should be painted 2 times, horizontally, vertically, and the color of the waterproof coating film is uniform and opaque, which is qualified. The color is uneven, there is a missing brush, and the bottom is unqualified.

Generally, it needs to be brushed 3 times to be waterproof.
