Then smooth the wall with cement, and then apply a layer of waterproof paint, for the load-bearing wall paint height must be at least higher than 30 cm, for the light wall, the entire wall should be coated with waterproof coating.

The tiles are then laid so that the joints are evenly coated with waterproof paint. Finally, the waterproof test is carried out to test that there is no penetration, and the waterproof is qualified.

1. How to do waterproofing the bathroom wall.

First of all, ensure that the bathroom wall is clean, no cracks, dry, and no falling off. Divide the waterproof coating into three parts, pour two of them into the container, add an appropriate amount of powder, stir well, and then pour the remaining liquid material into it and stir evenly; To paint it on the base surface of the wall, it needs to be painted twice, each time is about 1 mm, and it is necessary to wait for the previous process to dry before brushing the second time. If the cross painting method is used, the thickness of 1-2 mm is appropriate.

When the waterproof layer is dry, it is necessary to do a closed water test to check whether the waterproof construction is qualified.

2. What are the waterproof materials in the bathroom?

1. Hard mortar.

Hard mortar is more convenient, and then directly tiled after brushing, without the need to treat the coating again, and is generally used on the back surface of the top surface. However, if the base layer is deformed, it is prone to waterproof cracking.

2. Flexible mortar.

Flexible mortar is more elastic, so the base layer is prone to deformation and cracking, which is commonly found on the frontal surface such as walls and floors, but is not suitable for the backwater surface such as the top surface. If the waterproofing is not done well, it is easy to seep into the water.

3. Acrylates.

Acrylic is a pure liquid, no need to stir, open can be used, well integrated into the water, easy to combine with the ground gaps, wax wide to form a strong waterproof layer. After brushing, surface treatment such as brushing and sand blowing is carried out, which is easy to stick to the bend and pick the bricks, and the acrylate has a good waterproof function.

Conclusion: How to do the waterproofing of the bathroom wall and the common waterproof materials are introduced to you here, I hope it will be helpful to you, if you need to know more about relevant knowledge, please continue to pay attention to the Qeeka Home information platform.

We all know that the kitchen and bathroom are the places with the largest water vapor in the home, especially the bathroom, which needs to use a lot of water for bathing.

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.

Toilet waterproofing practices:

Basic material selection: new waterproof materials such as cement mortar, old ones such as acrylic are commonly used sanitary waterproof materials. We should choose based on the principles of easy construction, environmental protection and good quality.

The first step in how to do bathroom waterproofing is to brush the joints in place. The joints between the walls and floors of the bathroom and the joints between the water and water pipes and the floor are the most problematic places. During the construction, you must urge the workers to deal with these corners and corners, so the waterproof coating must be applied in place.

Bathrooms do waterproofing.

Pay attention to ground leveling before waterproofing; The ground is oriented to the slope of the floor drain, cement mortar or bean stone concrete can be used, but the surface should be flat. The slope near the door is small, and the slope near the floor drain is large, so you can grasp it according to the specific situation.

The ground is uneven, and it may be uneven when applying waterproof coating, or the ground is easy to crack because of unevenness, which will crack with the ground even if the waterproof paint is applied. 2. Strengthen waterproofing at the root of the pipeline; The pipeline passes through the root of the floor slab to strengthen the waterproofing. After the pipe root building sealing paste is sealed tightly, and the cement is smoothed and the foot pads are smoothed, the glass wire cloth reinforcement layer is 1 or 2 layers when brushing the waterproof coating.

The same measures are taken near the floor drain. 3. Waterproof wall treatment; The wall surface is clean and flat, without floating ash and small particles, and the original corner or slope angle is wiped at the junction of the wall and the ground. When brushing waterproof coating, paste 1 2 layers of glass wire cloth reinforcement.

4. Coating film thickness; The total thickness of the polyurethane waterproof coating film is required to be more than millimeters, which cannot be determined by the number of passes. The pipe root and the corner of the reinforcing layer are brushed first, and after the surface is dried at room temperature for 4h, then a large area is brushed and scraped, and there shall be no leakage and bubbling, and the next layer is painted after 24h curing after large-scale brushing. 5. brushing; The façade is painted first, then the plane, and the direction of the next painting is perpendicular to the previous one.

When the final coating film is semi-cured, the coarse sand particles are thrown to facilitate the combination with the cement mortar in the future. The waterproof layer on the ground should be painted 300 wide outside the bathroom door. The waterproof floor waterproof layer should be 200 meters higher than the ground, and the wall waterproof layer of the bathroom with shower should be 1800 meters higher than the ground (L8 recommends waterproofing the full wall).

The wall of the bathroom needs to be waterproofed, which is the DAO standard for building decoration and decoration, which cannot be ignored.

Answer, not waterproofing for a long time will also affect your residence, because there must be a room next door to your bathroom, and there is a simple decoration on the wall.

The waterproof height of the wall in the wet area of the kitchen and bathroom (such as the shower room and bathtub) shall not be less than 1800mm, and the waterproof height of the wall in the dry area shall not be less than 300mm.

The floor of the toilet structure must be tested for water storage, and the water storage shall be carried out by the general contractor, and after the completion of the water storage test, it shall be handed over and received by the supervisor, the owner and the general contractor. After the completion of the floor drainage system, after the completion of the waterproof layer of the decoration construction, the decoration construction unit will do the water storage test again, and the water storage test is strictly prohibited before the waterproof layer is not dry, if the water is found to be turbid or milky white during the water storage process, the waterproof layer is not enough to cure, the waterproof layer has been dissolved and destroyed by water, and the waterproof failure must be redone.
