Why does the latex paint fall off when you touch it, and the latex paint will fall off as soon as it

The first reason is the putty at the grassroots level.

Latex paint was painted without drying.

In this case, the latex paint will enclose the water in the bottom putty, and as time increases, the water slowly evaporates outward, and finally leads to the delamination between the latex paint and the putty layer. After that, there was what we call the case of latex paint peeling off.

The second reason is that water has ingress into the base layer of the wall. For example, the exterior wall of our home or the partition wall of the bathroom, due to the entry of moisture in the wall, then the internal putty will fail. The putty will be separated from the plastering layer when it takes effect, and the latex paint on the surface layer will peel off and fall off.

The third reason is that the surface layer is damp. For example, after the surface layer of latex paint is blistered by rainwater or its leakage, the latex paint will fall off directly from the wall. Therefore, the wall surface of latex paint basically cannot be soaked in water.

The latex paint will fall off when touched, and the main reason is that the powder of the base putty is serious, so that after the latex paint is painted, the latex paint will be hollow and bulging, and the latex paint will fall off as long as there is a touch. In such a situation, the latex paint that has been painted should be removed, for the putty that has been painted, it can be completely removed, and then the putty can be re-made latex paint, or the putty layer can be coated with glue or wall solidification on the putty layer of powder, so that the putty layer is firm and firm, and then the putty is flattened, and after sanding the sandpaper, the latex paint can be repainted.

Here's how to avoid paper tape sticking off latex paint:

1. The latex paint wall can only be pasted with masking paper, and its sticking power is not so strong, but it can be glued firmly. EndIt is best not to use scotch tape.

If the masking paper can still stick to the latex paint, it should be two situations: one is that the latex paint is too poor in quality, or too much water, and the paint film is too thin. Another is that the tape has been glued for too long and the tape has deteriorated. The tape should be removed as soon as possible after completion.

When tearing it off, be careful and take it slowly. It is best to have a utility knife in your hand, and if you bring it out (more than 5-in-1 lacquer, it is easy to bring it off, because the paint film is elastic), use a knife to cut it.

After the paint is painted, wait for the paint to dry before removing the tape. Paint that doesn't dry can easily get sticky.

Latex paint characteristics and **

Latex paint can be washed with water when it is dirty, which is the main reason to attract consumers to buy latex paint. The brush resistance of high-quality latex paint can reach more than 2000 times.

Latex paint pigments and fillers are inorganic minerals, will not cause harm to the human body, and the amount of additives in the latex paint system is very small, as long as the enterprise strictly checks, choose those products with less organic volatile content and no heavy metals, will not cause harm to the human body.

On the market, JFN-201 high-grade interior wall latex paint** is about yuan per kilogram, JFW-104 high-grade exterior wall latex paint** is about yuan per kilogram, and JFW-105 high-grade exterior wall latex paint** is about yuan per kilogram.

It can be said to be normal, but it should not fall off in large areas piece by piece. Because the transparent tape has good adhesion properties, when it is pasted on the latex paint wall and then torn off, the wall putty layer will generally be brought down, but it will not be as serious as you say.

In your case, there should be a problem with the quality of the wall putty layer, that is, the composition of the binder in the putty is too small, and the hardness of the putty layer is not enough, that is to say, the adhesion of the putty layer to the wall is too poor. Therefore, it can be considered abnormal!

On the wallpaper wall, before pasting the wallpaper, it is necessary to brush the wallpaper base film. The purpose of this brushing base film is to strengthen the putty layer on the wall, so that the putty layer has a certain hardness, so that the wallpaper will not fall off easily.

Hello, Xiaohai, a home expert, is happy to answer for you. Pro, the wall paint sticks off is actually a very common phenomenon, and the reasons for falling off are: 1. The problem of the contact surface of the grassroots:

When painting the wall paint, the wall is not clean, and the workers are lazy and do not polish and clean the wall, resulting in the weak adhesion of latex paint. 2. Weather or environmental problems: during construction or use, long-term exposure to humid environment leads to excess moisture in the wall paint, and when the wind blows or the weather is dry, the wall paint will shrink and tighten, resulting in peeling.

The former phenomenon is best consulted during construction, and in the latter case, such as brushing latex paint in the bathroom, it is best to use waterproof wall paint. 3. Wall reason: Although your wall is a new wall, it does not exclude this reason, the wall is not good, it will also cause the surface to crack and fall off, and the wall paint is easy to fall off.

If I can help you, you give a like, look forward to your like, dear, thank you.

Latex paint. The wall is easy to break, which may be a problem with latex paint. The paint film of exterior wall latex paint is relatively hard, and the water resistance is stronger, so it can be used in wet spaces such as toilets, so exterior wall paint can brush interior walls, but interior wall paint does not have UV resistance.

The function of not painting the exterior wall, the interior wall paint has high requirements for scrub resistance. Because the walls are easily soiled, families with young children will be even more troubled by graffiti. Latex paints with water-repellent formulations will naturally form a dense layer of water-repellent paint when they dry thoroughly.

With water or a mild detergent, you can easily wipe the stain clean without erasing the paint itself.

As an ordinary consumer, it is generally difficult to judge, let alone say anything about smell, viscosity, scrubbing resistance and other inspection methods, because this is all an afterthought.

And Nippon has a different series, there is a clean smell, water-based, my own home decoration house is used Dulux, I think it's not bad, of course, no matter what kind of paint is used, the new house is renovated or to open the window for ventilation for a period of time before moving in, after all, the body is the most important.

This can be reflected from all angles, although there are now many products that can replace latex paint, but for most home decoration latex paint is also the "standard" when decorating, how to choose latex paint in home decoration, need to be considered from the following four aspects: pigment is to determine the color of latex paint, like purple paint is potassium permanganate.

Copper sulphate for blue.

Wait. The adhesive determines the speed of drying, abrasion resistance, and gloss. The solvent is water, which is easy to understand. There are also some thickeners.

Fungicides or something.

This is more awesome, the brand has never heard of at all, it is said to be a newly registered brand, this brand is a paint, is a patented product that has just been developed, completely not, the only effect is that it can continue to release negative oxygen ions.

So the environmental performance is good. Oil-based latex paint is mostly used for exterior walls, which has anti-oxidation, weather resistance, anti-corrosion and other properties. The oil-based emulsion paint with these properties will have a higher content of formaldehyde, benzene and some other harmful gases, that is, its environmental performance is poorer.

When brushing on the wall with a roller brush, the latex paint is not uneven on the wall, and the paint film is evenly placed. If you want to spray with a spraying machine. The amount of water mixed with it may be about one-half or one-third of that of latex paint.

The sprayed latex paint does not have small granular objects on the wall. Then roll or brush with primer, topcoat. Because it is repaired, it is recommended to dilute the latex paint a little and brush it several times.

If the color of the topcoat is different from the original wall color and is unacceptable, it is recommended to repaint the repaired wall. It must be dry thoroughly between each coat before the next one can be made.

First of all, shovel off the paint on the wall, and protect the cement mortar layer while shoveling off the paint, which plays a good role in the later procedures. The paint shovel on the wall is clean, there can be no residue, after the overall wall shovel is clean, the indoor base layer is cleaned up, and the bottom layer can be brushed. The lighter the color, the better it is to paint, it is not easy to paint flowers, and it is okay to paint twice normally; If it is a dark color latex paint, it is generally a professional toning paint, and it can not be mixed with water when painting, and it is generally necessary to brush several times to achieve a good effect, and there is a phenomenon of flowers if there is less brushing.

The function of the primer is to solidify the wall and increase the adhesion of the interface, because the wall of our wallpaper needs to be brushed with a base film, and the wall surface of the base film can become strong and not powdered, and the cost of the primer and the base film is about the same, and the primer is white because of the addition of titanium dioxide! The viscosity of putty powder is not strong, the glue in the putty plays a role in connecting with various substances, the quality is not good, the viscosity is not enough, and the best paint is used, it will also fall.

That's a problem with both the paint and the construction. Generally, three parts of labor and seven materials are divided, in this case. Choose the brand paint when buying, supervise the work on the spot during construction, and let the workers collect several more times, and this situation will not occur.

Don't buy cheap paint to save money. One price, one goods. It is to dry whether the surface of the surface is white or sticky to the whitening phenomenon, if there is whitening phenomenon, the quality is poor, vice versa, but also to see that the surface scratches on the overall impact is obviously not obvious, are one of the factors to judge its quality.

This is true, and it is important to be very careful when using them, it is best not to touch them frequently, especially when the weather is very dry.

Yes, it's true, its quality is particularly bad, so it will trigger a lot of complaints.

It's true, this kind of wall is particularly easy to break, so now everyone still chooses wallpaper.

This is not true, if it is easy to break, it means that the base layer is not done well, and the putty is not scraped well.

Latex paint with tape sticks and falls off! Hello, glad to answer for you. Latex paint sticks off with tape, it is best to find a professional decorator to deal with it, and you can also remedy it yourself, and the following will explain the remedy.

1. The places that are glued off can rarely be patched with putty, then polished and smoothed, and finally brushed with latex paint. 2. If there are many places or large areas that are glued off by the adhesive, the entire wall needs to be renovated, otherwise there will be a color difference between the new and old painted walls after repair. 3. When the wall is renovated, if the wall does not have any blistering, peeling, hollowing, you can do not need to eradicate it, and stuff it on the wall with a wet cloth with water for about two minutes.

4. After shoveling off, the putty is polished and smoothed, and finally brushed with latex paint. Hope mine can help you! Do you have any other questions?

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

2. Shovel the wall skin: Remove the part of the original wall that has been soaked in water 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: In general, use kraft paper tape and white latex to stick the cracks.

5. Leveling: uneven walls need to be leveled, generally gypsum is more commonly used, and the uneven difference is better than centimeters.

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, and generally use 400-500 sandpaper for softer putty.

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.
