What is the situation when the putty powder of the cement wall batch protrudes out of the soybean si

Putty powder for cement wall batches.

What is the reason for the appearance of protruding soybean-sized bags, there is a product space decoration.

One of the reasons: generally the wall foundation at the bulge is not well treated, one is that the construction is not clean and floating, and then the wall is oily or waxy things, the second reason: the construction is not standardized enough, and the wall base is not dry on the latex paint.

surface layer, it is also possible that it is scraping putty.

Before, the original cement layer was not cleaned up.

Reason 3: The material itself is not good, such as the putty glue problem.

Reason 4: The interior of the wall is damp.

The specific steps are, first shovel off the blistered part of the cement wall, seal the bottom with a primer, dry and then scrape the putty, and then polish, primer and topcoat. If you want not to affect the aesthetics, you should spray (brush) the entire blistered wall at the end, because of the newness, the texture will be poor.

The putty powder of the cement wall batch is prominent, and the soybean-sized bag is putty powder, which is not evenly smeared, but must be repeatedly smeared, and it must be smeared evenly, so that there will be no bag.

In this case, it must be that the original base layer has not been treated well, and there is a leakage point, or a wet place.

If there is a bubble the size of a soybean that has been boiled out, it is caused by the wall not being cleaned.

The newly renovated house had just moved in, but not long after, the wall was bulging, and I instantly felt that the previous efforts were "in vain". What should I do if the latex paint wall is bulging?

Detailed analysis of the causes and treatment methods of latex paint wall bulging:

Reason 1Improper treatment during decoration construction, the wall base is not dry enough, or the original cement layer is not cleaned up and the putty is directly brushed;

Treatment: Before applying latex paint, the preliminary work of decoration should be done, and the doors and windows of each room in the room should be opened, so that the indoor walls and floors should be dried as soon as possible. If conditions permit, it can also be dehumidified to remove moisture from the air to avoid moldy and odorous latex paint in the hot flashes during decoration.

Reason 2: The quality of the material itself is not good, such as the quality of putty;

Solution: It is recommended not to be greedy for cheap materials when purchasing materials, and to choose well-known and high-quality materials. In addition, when scraping putty and brushing latex paint, it is necessary to pay attention to the process arrangement, stop work for a few days after scraping putty to ensure that it is dry, and extend the time to dry after the first application of latex paint.

Reason 3: Whether the wall is damp for a long time, the long-term dampness of the wall will also cause the phenomenon of latex paint wall bulging;

Treatment: Check whether there are faucets or other equipment that may cause water seepage, if so, repair the faucets and water pipes to ensure that these equipment are no longer seeping, and remove the wall surface of the bulging part by knocking off the wall surface of the bulge, shoveling off the wall surface of the blistered part, and re-processing.

For the newly painted wall on the bulging situation, we should also encounter it more often, I hope the introduction of latex paint wall bulging causes and treatment methods can help you.

What should I do if the paint on the wall is powdered? Experts teach you how to deal with the problem of wall paint peeling and bulging.

First, the plastering technology is not standardized, the wall base layer is not cleaned before plastering, and it is not treated according to the requirements, for the wall of different materials.

surface, the steel wire mesh is not set up in accordance with the specifications when connecting, the wall is not fully watered, and the exterior wall is not divided into grids or the grids are too large.

Second, the material is not soaked in sufficient water, and it is not soaked in water or soaked enough before paving. Ceramic tiles, especially glazed tiles, should be soaked in water for 2 hours before paving.

After the tile fully absorbs water, take it out to dry or wipe it clean. If the brick is not saturated with water, it will absorb the mortar prematurely.

The moisture in the mortar will cause the mortar to shrink and hollow, and it will also affect the strength of the paste.

Third, the filling is not full, the mortar is not full when the tile is paved or the tile is not gently knocked and squeezed densely, which is a situation for.

Cutting corners and saving cement mortar is just to save time and be sloppy.

There are many reasons, generally caused by the grassroots treatment is not done well, you can snatch the bulging place to see if it is delamination, whether there is mold, hair, alkali return, etc. Whatever the reason, you have to grab the drum first. If it is delamination, that is to say, two skins, grab it and brush it with a good interface agent, and then scrape it flat with gypsum or putty.

The solution is to pay attention to indoor ventilation, use good water-resistant, alkali-resistant and anti-cracking latex paint and putty powder, such as snow maple latex paint and snow maple putty powder have a professional water and alkali resistance function, stirring fast and trouble-free, simple brushing and simple operation, waterproof and anti-drumming and anti-cracking, surface drying time is fast, I hope to help you.

"There are many reasons for drumming:

1. The base layer is not clean, the original putty layer has not been cleaned up, and the newly bought putty powder has a relatively large grip, which cracks the original putty.

2. The first putty is not dry and the next batch is scraped.

3. The putty is too thick or too thick when scraping.

This kind of problem often arises, usually in a small area, and there are multiple places. It is a good thing that the latex paint has not been brushed yet, and it is a good thing that all the drumming is shoveled off as soon as possible, and the putty is scraped again, there will be no problem, and it will not appear in the future. "

There are many reasons for blistering on the wall: 1. Poor quality of paint products.

2. The construction personnel are poor and not careful.

It is best to redecorate the wall, now there is a kind of paint on the market that is waterproof and mildew-proof, wear-resistant, strong adhesion, feel and visual like wallpaper, wallpaper that can be scrubbed like the floor.

1. Water on the wall: Moisten the original wall, save effort when shoveling. 2. Shovel wall skin:

Remove the water-soaked part of the original wall until the cement mortar wall or putty layer is exposed. 3. Interface agent: The wall is coated with interface agent, and the interface agent must be brushed, and it must be brushed evenly.

4. Cracks: Under normal circumstances, the cracks are pasted with kraft paper tape and white latex (but there is no guarantee that 100% will not crack again). 5. Leveling:

The uneven wall needs to be leveled, and the general plaster is more commonly used, and the uneven difference does not exceed the centimeter. 6. Patching: Generally, non-load-bearing walls such as light walls and insulation walls need to be pasted, try to choose a better texture wall cloth and white latex, if there are conditions, you can use mesh cloth, the relative anti-cracking effect will be better.

7. Batch scraping putty: it is better to choose putty with higher particle fineness and harder texture, and you can also add a certain amount of white latex to the putty, which can improve the hardness of the putty. 8. Grinding:

Try to use finer sandpaper, generally softer putty with 400-500 sandpaper. 9. Primer: The primer must be brushed evenly to ensure that every place on the wall is brushed, if the wall eats a large amount of paint, the primer is best to add a little more water to ensure that it can be painted evenly.

10. Patching: After the putty is polished, there will be some flaws (pit eyes), which are generally difficult to see, and it will be obvious only after brushing the paint, at this time it is necessary to make up, pay attention to the patch must be polished and smooth, and then brush it with a primer with a little more water, so as not to have color difference when brushing the topcoat because of the different draught with other walls. 11. Topcoat:

Do not add too much water, it will affect the thickness of the paint film, the feel and the hardness of the paint film, try to choose a better tool, the hair of the drum is not too short, but it must be fine. 12. Maintenance: The latex paint will dry 4 hours after brushing, but the dry paint film has not reached a certain hardness, which should be cared for, and there should be no scrubbing or any contact with the wall within 7-10 days.

Hello, the situation of the wall bulging, most likely because of the dampness inside. The fundamental solution is to knock down the wall at the bulge and reprocess it.

The specific steps are to shovel off the blistered part of the cement wall, seal the bottom with a sealing primer, scrape the putty after drying, and then polish, apply primer and topcoat. If you want not to affect the appearance, you should respray or brush the entire blistered wall at the end. Hope it solves your problem.

It is caused by water seepage and moisture on the wall.

Generally speaking, the wall bulge may be due to the fact that the wall foundation is not treated well, one is that the impurities and dust are not cleaned during construction, and then the wall is oily or waxy. Or the alkali content of the wall is too high.

Then the construction is not standardized enough, and the latex paint surface layer of the wall base layer is not dry will also cause the wall to bulge, and it may also be caused by the original cement layer not being cleaned before scraping the putty. Or there is a problem with the quality of the materials used.

Then there is one of the most common reasons, the wall is swollen caused by moisture, water seepage in rainy days or water seepage into the wall, and the latex paint becomes blistered after soaking. To solve the problem of wall bulge, in fact, it is best to be cautious and prevent it during construction.

So how to deal with the wall bulge? The specific steps are to shovel off the blistered part of the cement wall, seal the bottom with a primer, scrape the putty after drying, and then polish and finally brush the latex paint.

Partial wall bulges can only be partially scraped and repaired, if it is a large area of bulges, all must be scraped and repaired, but if it is caused by the putty of the wall base, you need to remove the putty, and choose the appropriate putty to scrape again.

It should be noted that when dealing with the wall bulge, the uneven wall must be shaved and smoothed, and the holes or depressions must be watered with 1:3 cement mortar, moistened, blocked, and smoothed in layers. And it is best to choose moisture-proof putty paste when scraping putty.

Finally, when mixing the paint, pay attention to the paint should not be too thin, excessive moisture will affect the adhesion of most paints and cause bulging.

The construction quality is not up to par, the materials are not up to par, and the water leakage on the upper floor may be caused.

Hello! This situation may be caused by the cement mortar, mixed with lime particles that have not yet completely melted, if this is the case, it is quite normal. It is rare for putty powder to have this kind of problem.

In your case, I think the cement mortar is not well maintained, and the increase in the moisture of the mortar after the stucco paint leads to the secondary hydration and bulging.

There are two possible reasons why there are several bulges on the walls after 4 months of latex paint:

1. The possible reason is that there is a layer of cement floor in the house, and the wall will "eat" the water;

Second, it may be that the water ran through the water during the renovation.

Treatment: Knock off the hollow drum part and repaint the wall, pay attention to the need to wet the wall the day before painting. The thickness of the painting should not be too thick.

Hello brother, if there is a hollow drum, there are only two reasons, either the wall is not dry when the paint is applied or the water leaks after that; Then the wall contains alkaline volatile substances before you apply the paint, and the alkali resistance of the primer is not strong, and there is a hollow bulge. When applying paint, the pH of the wall should be around 9ph.

Maybe it's caused by a leak in the sewer pipe. There is also the problem of putty powder. I advise you not to be angry, it's good to do it all over again!

That's because there is still some granular lime in the batch of ash, and the damp lime rises. Hope it helps!!

The original wall plastering was hollow, because there was no watering or brushing or no interface agent before plastering. You can only shovel the plastering layer and redo it, pay attention to the reasons mentioned above.

Caused by alkali return! But even the cement fell off together, which was too serious. I think the floor of your house must be wet, even if you don't think it's wet.

Clean it up, along with the cement;

cement mortar, stucco plaster and other reprocessing bases;

After drying, scrape putty and brush latex paint.

Note that the putty must be water-resistant and alkali-resistant. It is better to brush the anti-alkali primer before scraping putty.

Causes of bubble hollowing:

The base layer is too dry, the wall water absorption rate is too high or the base layer with high cement grade is prone to bubbles.

The base is too rough, there is no polishing and smoothing, and the speed of batch wall in the process of putty construction is too fast, so that the putty layer and the base layer are not close enough to form a sandwich; The putty is too thick to scrape in batches at a time and is easy to blister.

The moisture content of the base layer is too high and the density is too large or too small. Because it contains abundant voids, the moisture content of putty is high, so it is not breathable, and it is easy to make the lower part of the putty powder layer contain air during the construction process, which is not easy to discharge, so it is easy to blister.

The bursting blistering that occurs after a period of construction is mainly caused by uneven stirring when the putty powder is stirred. The unevenly stirred slurry contains powdery particles that have not had time to dissolve, and during construction, brushing on the surface of the wall, there is no big disadvantage, but after a while, the powdery particles begin to absorb a lot of water, and then they expand and burst. As a result, the surface of the putty layer is blistered.

Solution: The base treatment should be clean and flat. If necessary, brush a layer of surface agent for surface treatment, preferably with an emulsion type that is more environmentally friendly.

After the putty powder is stirred evenly, let it stand for about 10 minutes to allow the various ingredients to fully moisten and dissolve, and then stir it again with an electric mixer before putting it on the wall.

During the construction of putty, the wall should be scraped and pushed repeatedly, so that the putty and the base layer are fully contacted, moistened, infiltrated and diffused.

If there is blistering on the second or last surface layer of construction, the foaming should be broken with a scraper before the watermark is eliminated to ensure that there are no bubbles on the putty surface.

If there is a large area of blistered putty surface, use a shovel to directly break the small bubble mouth, and re-scrape the blistered surface layer with interior wall putty.
