There are some small cracks on the surface of the ground after the bathroom is waterproofed, is it n

It is necessary, it is very beneficial for yourself and downstairs, and it will avoid a lot of trouble.

Of course, it is necessary to redo the waterproofing, because this small crack is likely to leak later, and now it is found that it must be remedied.

It is necessary, because after the waterproofing is done, such cracks appear on the surface, so after living for a long time, the cracks will definitely be even greater, so at this time, it should be re-waterproofed immediately.

Of course, if there is a crack, it means that the waterproofing layer has failed, and the waterproofing must be done again.

Waterproof is a layer of waterproof film to achieve the waterproof effect, just like a plastic bag is damaged, of course, it will leak if it is filled with water, and it needs to be strengthened, and it can be used with flexible waterproof coating with polypropylene cloth. Paint more than twice.

Because I did not see the site, it is impossible to determine the size and severity of the gap in the waterproof layer, so it is recommended to do a closed water test for 48-72 hours to determine whether it will affect the waterproofing effect.

The purpose of the closed water test is to check whether there is any omission in the waterproof construction and whether the waterproof function is normal

1. After the waterproof construction is completed, you can do the closed water test after the waterproof layer is completely dry;

2. Temporarily block the floor drain and the perimeter of the pipeline mouth;

3. Build a 20cm high retaining wall at the door;

4. Start to store water, with a depth of 5-20 cm, and mark the water level;

5. Water storage time 48 72 hours;

6. After the water is closed on the first day, see if the water level has dropped significantly, if so, please check whether there is leakage around the roof and pipes downstairs in time, if not, continue to close the water;

7. On the third day, the water is closed, and the downstairs ceiling and roof pipes are fully inspected.

8. Carry out the next process after being fully qualified.

There are many reasons for the cracks on the surface of the bathroom floor after waterproofing: generally the dry shrinkage cracks caused by excessive thickness during construction, especially the corners, pipe mouths and uneven base surfaces, these parts are the key parts of waterproof construction, and the construction personnel often carry out multiple brushing without complete surface drying, resulting in excessive thickness of the coating film, and dry shrinkage cracks are caused by the difference in the cold shrinkage coefficient of the thermal barrier, which will lead to water seepage.

There are basically only two solutions to this situation:

First, if there is no water seepage on the ground, a special anti-seepage liquid (glue) can be used to plug it.

Second, if there is water seepage, the only way to do it is to re-do the waterproofing treatment. When redoing it, pay attention to the humidity and thickness of the brush.

There are many cracks on the surface of the bathroom floor after waterproofing, and this situation needs to be reworked and redone.

The reason for this is that the base layer is not cleaned, and the water-based waterproof coating used is not properly formulated, resulting in dry shrinkage.

When doing waterproofing, the waterproof coating should be moistened with water first, and then evenly coated with waterproof coating, and the corners and pipe roots should be reinforced.

If the waterproofing fails, you have to do it again, or it is a water filling test

If the waterproofing of the bathroom is not done well, it is to seep water downstairs through the cement and seep water down. The waterproof layer of the bathroom floor is damaged, which does not mean that it will definitely leak. We all know that as long as the ground stays dry, there is no possibility of water leakage.

In the same way, even if the waterproof layer is good, if the ground is waterlogged for a long time, there is still a possibility of water leakage and seepage.

If there is a problem with the waterproof layer of the bathroom, then you must be careful when taking a shower and washing clothes, and clean the floor immediately after washing, so that you don't have to worry about water leakage.

Water leak repair

Generally speaking, it is only a temporary and emergency measure to make up for the non-leakage with cement, because the non-leakage of water is a rigid waterproofing and cannot resist some settlement deformations and cracks. However, this problem also depends on whether the smashed tiles are wall tiles or floor tiles.

This is usually not a big problem for walls, because there is no water pressure and the water on the wall can easily run away. In the case of confirming that the water pipe is repaired in good condition, the cement is repaired without leakage, and the tile is paved and then repaired, which can basically solve the problem of water leakage.

Floor tiles. The situation is much more complicated, as water on the wall will flow to the ground very quickly, and the water on the ground will not flow away as quickly as the wall. That is to say, the waterproof requirements of the ground are much higher than that of the wall, and the wall is more important than moisture-proof.

If the tiles are smashed on the ground, the best way to deal with them is to open all the floor tiles, clean them up and redo the flexible waterproofing, and then do a water storage test.

There is no problem with tiling later.

Summary. Hello dear, it may be because the weather is too hot to crack the cement slurry on the polypropylene cloth, and the cement slurry on the polypropylene cloth may be too dry and the surface is cracked. If the opening is not very large and deep, it has no effect on the waterproof quality.

The bathroom is waterproof with polypropylene cloth, and today I saw a lot of small cracks on the ground, what's going on??

Hello, I am glad to serve you, I have received your question, and I am sorting out the answer for you, it takes time to guess the word on the bridge, and please be patient and wait for a while, and answer it for you immediately! Potato eyes.

Hello dear, it may be because the weather is too hot to crack the cement slurry on the polypropylene cloth, and the cement slurry on the polypropylene cloth may be too dry and the surface is cracked. If the opening is not very large and deep, the amount of buried oak for water quality prevention will sound without shadow.

The protective layer on the polypropylene, the shrinkage crack of the material itself, pay attention to whether the seams of the polypropylene are tight. Polypropylene is better than polyurethane waterproofing.

There are cracks in the base layer, there is no repair, and a rigid material of the mortar type is chosen, which is not ductile.

It was unable to resist the deformation of the base cracks, so cracks appeared. To remove the waterproof layer in the cracked area, remove the cracked area in the lower mortar base, re-level the treatment, and use a flexible waterproof coating.

Waterproofing was re-applied. Waterproofing construction is a door technical work, and even the slightest negligence can cause irreparable losses. Waterproof coating is one of the main materials, so you should also pay attention to the choice of materials and choose big brands on the market.

Although it is waterproof, but there are cracks on the surface, is it necessary to do it again? Any other suggestions? The family miscellaneous divides this question equally into two issues, one for the other.

The first problem is what happens after the waterproofing is over, so how do we judge the quality of the waterproofing based on these questions. The second question is about specific proposals for waterproofing works.

Waterproof, with cracks in the surface, means waterproof paint for the floors of my house.

When finished, these waterproofing materials are basically hardened, but many cracks appear after solidification. This is also a common problem that occurs after the completion of many waterproofing projects. To this kind of question, the answer given by the family miscellaneous is that it must be waterproof again.

Because the following problems may occur after cracks: the waterproof paint we apply has cracked, which is unqualified. According to the quality requirements of the waterproof coating, the waterproof surface we apply must be a coating that looks uniform, and the surface of the coating must be very uniform and there must be no cracks.

If a crack occurs on the waterproof surface, there may be no water leakage for the time being, but there is a problem that the thickness of the waterproof membrane is seriously reduced. For example, a crack in the floor is split in half, but if it is not transparent, in fact, our waterproof coating is only half thick, and its waterproofing effect will be significantly weakened.

Waterproofing is a very important construction stage and concealment project in the bathroom.

If you want to fool the waterproofing, you can lie to you after the renovation and turn the bathroom into a leaky toilet. Therefore, once the waterproofing project is completed, it must be re-treated when there is a quality problem. In this way, we can ensure that the use of the toilet is not leaky.

In this way, you can use the bathroom with peace of mind, and you are also responsible for the residents downstairs. If you want to know whether there are cracks in the bathroom waterproofing and whether the waterproofing needs to be redone, you must first know what the reason for this happens, analyze the reason, and you can know the correct way to deal with it.

After the waterproofing is done, there are some small cracks on the ground, and if there is no water leakage, there is no need to re-do the waterproofing, unless there is water leakage, and the general problem is not big.

To redo the waterproof. Because waterproofing is very important when decorating a house. At this time, we must pay attention to it.

Of course, it is necessary to do it again, because these small cracks are likely to cause water leaks, and if the water leaks later, it will be even more troublesome to repair.

There are many possibilities for this, and there are impurities mixed in if they are not thoroughly cleaned before doing it; The master's waterproof brush is too thick; The proportion is wrong when proportioning; There is a problem with the paint itself; or the paint is not completely dried and the water is closed; It is recommended to find a serious and responsible professional master to do it.

Usually because of the excessive and thick coating during construction, the cracks are caused, so when you do waterproofing, you must master the amount and don't paint too much.

This is due to the fact that the inside of the ground is damp, and the surface of the ground is too dry due to the use of a heater to dry it, causing it to swell and crack.

<>Thank you very much for waiting, I put your question on the back for you;; There are many cracks on the surface of the bathroom floor after waterproofing, and the reason is generally the dry shrinkage cracks caused by excessive brushing during construction, especially the corners, pipe openings and concave and convex.

The uneven base surface, these parts are the key parts of waterproof construction, and the construction personnel often carry out multiple brushing without complete surface drying, resulting in excessive thickness of the coating film due to thermal barriers.

Dry shrinkage cracks are caused by different cold shrinkage coefficients, which will lead to water seepage in serious cases. There are basically only two solutions to this situation: first, if the ground does not occur.

The phenomenon of water seepage can be plugged with a special anti-seepage liquid (glue). Second, if there is water seepage, the only way to do it is to re-do the waterproofing treatment. When you do it all over again.

It is necessary to pay attention to the humidity and thickness of the brush.

There are many cracks on the surface of the bathroom floor after waterproofing, what should I do?

Hello noisy, I'm glad to be able to answer your questions for you, please wait two minutes, Brother Shenghui, I see your question here, and I'm going to inquire about the relevant information for you, the teacher also needs time to type, please be patient and wait for two minutes! Please don't end the consultation |! <

If you need to remove all the waterproof paint you made before, you don't need to do it again.

It would definitely be the best if you went.

If you don't remove it, brush it directly with another waterproof.

That's better not to, the product is different!

What if the shovel can't be shoveled.

Use a syringe to inject water into the front and under the waterproof putty before shoveling off with a spatula.
