How to redo the bathroom waterproofing

1. Clean the surface and the base layer of the bathroom, including dust, sand, cement, etc.

2. Grassroots treatment, ground leveling and slope finding, if the wall has cracks, hollow drums, and defects, it is smoothed with cement to ensure that the base is firm and smooth.

3. The yin and yang angles should be arced, and the yin and yang corners of the bathroom and the root of the water pipe should avoid dead angles, make an arc and straighten.

4. The key parts are waterproof, and the parts with the largest probability of water leakage are mainly the yin and yang corners and the root of the water pipe.

5. For the first time waterproof, it is recommended to use a brush, do not use a roller brush, the brush is more detailed and has fewer loopholes.

6. The second waterproofing, the second waterproofing and the first waterproofing should have a cross way, which can reduce the possibility of missing brushes. Waterproofing is generally done two to three times, and the thickness of each pass is controlled around the right.

7. The threshold is also a key part of waterproofing, and there is a possibility of water seepage at the threshold, so extra attention should be paid when brushing waterproofing. The threshold of the control door is 2-3cm higher than the bathroom, and the threshold stone should be wet pasted, and it is best to paste the threshold stone first, and then focus on brushing the side of the threshold stone.

Whether it can be directly repaired depends on the original waterproof material, the suggestion is to eradicate the original waterproof, clean the base surface after the waterproof material, after the closed water test is done, and then lay the tiles, remember, the slope should be found well, let the water flow faster, the probability of leakage will be less, waterproof construction pay attention to the roots, yin corners and other details! Don't leave the floor tiles empty! Provide free professional technical consultation for concrete waterproof leakage repair.

What is the waterproofing layer made of? If it is made of polymer cement-based waterproof coating, choose the same brand of waterproof coating and do it directly in the place where the hole is broken. After trimming the waterproof layer of the hole (digging out the damaged, peeling, etc.), cleaning the base surface, and applying the waterproof paint in two cross-cross ways.

Note: The newly painted waterproofing layer should overlap the old waterproofing layer by at least 15 cm long, and the total thickness of the waterproofing layer should not exceed 2 mm after two coatings.

If the waterproof layer is other waterproof materials, it is recommended to remove the original waterproof layer (the most ideal and effective method), clean and smooth the base surface to do the waterproof layer, do a 24-hour closed water test, no water leakage, and then lay a covering decorative layer.

If it is a material of the same nature and brand, you can do it directly on the top, but your new waterproof must be done as a whole, and the thickness should be sufficient, do not consider the original waterproofing at all, and repair the hole before doing the new waterproofing, so that there is a double protection effect.

Do holes work? If it is useless, it is best to fill it in after doing waterproofing, if it is useful, wear the casing at the hole, the cement mortar around the casing, and reapply the waterproof coating with the same component (to ensure that it does not react with the original paint) on the original waterproof layer after drying, at least two, preferably three (that is, the first waterproof coating is the first after drying, and the new coating layer is the second layer on it, and so on).

The landlord's house should be the decoration construction project in the construction of the waterproof surface has not been protected and damaged, according to your statement should be the same kind of paint, can be painted directly, to ensure that the thickness of the waterproof layer meets the requirements, the rest of the waterproof construction process of the quality control work is not wordy, the key is that the waterproof coating must be closed water test after the construction (the state stipulates that 48 hours without leakage is qualified).

Yes, you had better buy the same brand of waterproof paint to match it best, and when you paint, be sure to extend the painting area.

If you break a few holes, boil them with tar, pour them into the broken holes, and then make a waterproofing one, which is better.

It is not recommended to apply it directly. Now in a kind of waterproof glue. Just brush it up. You can try.

Yes, but it must be of the same nature and quality.

Yes, but not too thick, otherwise it will crack.

Toilet waterproofing practice 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.

Toilet waterproofing practice process 2:

Brush the waterproof paint a 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.

Make sure the floor of the restroom is stable. If you need to replace the floor tiles in the bathroom, after chiseling off the original floor tiles, be sure to level the floor with cement mortar first, and then do waterproofing treatment. This avoids leakage of the waterproofing coating due to uneven thickness.

Sanitary joints should be painted 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 areas.

Wall treatment is also important. In the general toilet waterproofing treatment, the wall should also be made about 30 cm high waterproof paint to prevent water from penetrating the wall. However, if the wall of the bathroom is a non-load-bearing lightweight wall, the entire wall should be coated with waterproof paint.

The waterproof experiment must be done. After the construction of the toilet is completed, all the sewer in the toilet is blocked, and a 25 cm high "barrier" is built at the door, and then 20 cm high water is poured into the bathroom.

Keep the toilet drain pipes clear. All sewer pipes in the bathroom, including floor drains, plumbing pipes for sanitary ware, etc., should be kept unobstructed.

1. Clean the surface and the base layer of the bathroom, including dust, sand, cement, etc.

2. Grassroots treatment, ground leveling and slope finding, if there are cracks, hollows, and defects on the wall, use cement to smooth out the base layer to ensure that the base is firm and smooth.

3. The yin and yang angles should be arced, and the yin and yang corners of the bathroom and the root of the water pipe should avoid dead angles, make an arc and straighten.

4. The key parts are waterproof, and the parts with the largest probability of water leakage are mainly the yin and yang corners and the root of the water pipe.

5. For the first time waterproof, it is recommended to use a brush, do not use a Bibei roller brush, and the brush is more detailed and has fewer loopholes.

6. The second waterproofing, the second waterproofing and the first waterproofing should have a cross way, which can reduce the possibility of missing brushes. Waterproofing is generally done two to three times, and the thickness of each pass is controlled around the right.

7. The threshold is also a key part of waterproofing, and there is a possibility of water seepage at the threshold, so extra attention should be paid when brushing waterproofing. The control threshold is 2-3cm higher than the bathroom, and the threshold stone should be wet pasted, and it is best to paste the threshold stone first, and then focus on brushing down the side of the threshold stone.
