How to do the waterproofing practice of the bathroom floor, and what is the thickness requirement of

The total thickness of the polyurethane waterproof coating film is required to be more than millimeters. It can't be decided 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. There shall be no leakage and bubbling. Brush a large area for 24 hours and then apply the next layer after curing.

5: Paint the façade first and then paint the plane, and the direction of the next painting is perpendicular to the previous one. When the last coating film collapses the stool and stool is semi-cured, the coarse sand particles are thrown, and the group travels to combine with the cement mortar in the future.

6: The waterproof layer on the ground should be painted out of the bathroom door 300 wide rough beat. The waterproof floor waterproof layer should be 200 above the ground, and the wall waterproof layer of the bathroom with shower should be 1800 above the ground

The thickness of the waterproof coating is about 1-2mm.

When brushing, use a brush or roller brush to apply directly to the base surface, and the strength is used evenly, and the brush should not be missed; Generally, it needs to be painted twice, and the thickness of each painting should not exceed 1mm;

After the previous one is slightly dry and solidified, the next painting is carried out, and the front and rear vertical cross brushing are generally 1-2mm; If the coating has already cured, moisten it with water first when applying another layer.

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.

Waterproof paint thickness: about 1mm. The root node of the waterproof pipe in the bathroom should be focused on: use anti-cracking glass fiber mesh + Yuexiu pipe root professional ultra-soft anti-seismic coating, try to choose whether the color is missing or not, you can see it intuitively!

Bathroom floor waterproofing practices:

1. Easy to operate, only need to stir on site to use;

2. It can be constructed on a wet base surface (but there can be no stagnant water);

3. It can resist high hydrostatic pressure, and the front water surface and negative water surface are effectively waterproof;

4. It has a certain toughness, which can cover small cracks and resist slight vibration;

5. Good abrasion resistance, good adhesion, after drying, it can be directly plastered, leveled and pasted with appropriate tile adhesive on the waterproof layer.

Bathroom floor waterproofing practices:

1. Clean the base surface and moisten it fully; Use a brush and scraper to evenly coat the stirred slurry on the treated substrate;

2. After brushing a layer, wait for it to dry slightly (just not sticky) and then brush the second layer, and after the waterproof layer is completely dry, you can directly paste the facing tiles with suitable tile adhesive;

3. Dosage: ,

Toilet waterproofing specific process:

Bathroom waterproofing process 1: brush the waterproof paint for the first time. Before construction, it is necessary to ensure that the ground is dry, and the waterproof coating should be coated with no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off. The coating height is consistent, and the thickness should meet the requirements of the product.

Bathroom waterproofing process 2: brush the waterproof paint for the second time. It is important to note that the second application should not be carried out until the first coat has dried, depending on the characteristics of the product.

If the interval is too short and the first coat of paint has not yet dried, the waterproofing effect will be greatly reduced.

Toilet waterproofing process three: lay a protective layer. In order to prevent the subsequent construction from damaging the waterproof layer, it is necessary to lay a protective layer on the surface of the waterproof coating. The protective layer should be completely covered with the waterproof layer, no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

Toilet waterproofing practice process four: closed water test. During the closed water test, the water at the highest point of the ground should not be less than 2 cm, and it should be stored for at least 24 hours, and it will be qualified only after observing that there is no leakage. If there is a leak, it needs to be redone, and it must not be negligent.

1. Ground treatment.

Before waterproofing, be sure to level the ground, if the ground is uneven or the effect is not good, it may cause cracking and leakage caused by the uneven thickness of the waterproof coating. Floor drains, wall corners, pipe heels and other joints should be painted with high elasticity and flexible waterproofing, because the joints between the wall and the floor of the bathroom will be displaced, and water seepage is most likely to occur.

2. Wall treatment.

If the bathroom has a shower room, the waterproof should be 180cm, and if there is a bathtub, the waterproof height of the wall adjacent to the bathtub should be 30cm higher than the bathtub

3. After the waterproof layer is done, a certain amount of time should be left to make the waterproof layer better integrated with the building, and then the protective layer on the waterproof layer should be paved with floor tiles, and in the construction process, it must not be sloppy. Try to protect the waterproof layer as much as possible.

4. Waterproofing is a concealed project, and the subsequent construction may also damage the waterproof layer, if the floor tiles have been laid, do not smash the floor tiles, use professional waterproof materials to plug all the gaps and do a good job of waterproofing. It is also suitable for waterproofing projects after the failure of the waterproof layer in the bathroom.

First clean the bathroom floor needs to be waterproof base surface, keep it dust-free, oil-free, sand-free, and water-free, and then paint it with HG203 sealing waterproof coating, and the thickness is on it.

Brush the bathroom waterproof paint is actually very simple, first prepare two tools: roller coating, brush, the product is selected Yuexiu K11 waterproof paint toilet special, the waterproof effect is good, the construction steps are as follows:

First, clean the base surface first.

2. After opening the lid, pour out the liquid material with a good proportion, and then slowly pour the classification into it and stir it while pouring it out.

3. Product brushing: large areas are rolled with a roller, and the yin and yang corners are painted with a brush, and it is recommended to do it twice to ensure that there is no leakage of construction, and the thickness is on it.
