My wall has been painted with latex paint, how to remedy it now if I want to install a gypsum line?

1. Putty: It is better to choose high fineness and hard putty, and you can also add some putty white latex, which can improve the hardness of putty.

2. Grinding: try to use finer sandpaper, generally soft putty (such as 821) with 400-500 sandpaper, hard texture (such as wall lining, easy to quack) with 360-400 is not better, if it is too coarse sandpaper will leave deep sand marks, paint can not be covered. The sanded walls must be thoroughly cleaned to avoid too much dust that can affect the adhesion of the paint.

The bump does not exceed 3 mm.

3. Primer: The primer must be brushed evenly, make sure to brush every place on the wall, if the wall eats a lot of paint, the primer is best to add a little more water to ensure that it is evenly painted. Do not think that because it is a roller that uses almost a drum primer, the effect of applying the primer will directly affect the result, using the same texture.

4. After the putty is polished, there will be some flaws (pit holes), which are generally difficult to see, only after the paint brush can be very clear again, at this time it is necessary to find a patch, pay attention to the patch must be polished smooth, and then add a little more water, a little bit of primer brushing again, so to eat, because with the other water wall paint with the color temperature.

Shovel off the putty at the position of the plaster line.

It has been re-brushed, and now the products in the paint industry are basically homogeneous, and there are many brands on the market. When we buy coating products, we should look at their hardware conditions (various technical standards and environmental protection standards); Secondly, for consumers, it is to look at the service, after all, this thing is "three points of paint and seven points of painting", and the quality of the construction has a great relationship. Market research, like Carberry paint, red apple paint, Dulux paint are good in all aspects.

You just pretend, it doesn't matter.

When pasting the gypsum line, it is inevitable that the wall will be uneven, and there may be gaps between the gypsum lines.

The interface part of the gypsum line should be paid special attention, the smooth and smooth gypsum line can achieve the beautiful effect, the joint part should pay attention to scraping the plaster, and then be careful when docking, the line and the pattern should be aligned, and the gypsum line should be cleaned immediately after installation, otherwise the stains may not be cleaned after the plaster solidifies.

It can be pasted, but there must be certain measures, after the line is set, use a small hammer to make small dots on the wall, and then apply the plaster line, you can stick it very firmly.

Gypsum line is the decoration material of the house, the main interior decoration. It can be brought with a variety of patterns, practical and beautiful. It has the functions of fireproof, moisture-proof, heat preservation, sound insulation, heat insulation, and can play a luxurious decorative effect.

Gypsum is an airtight cementitious material, and gypsum relief decorative products must have a corresponding thickness to ensure that their intermolecular affinity reaches the best degree. So as to ensure a certain service life and integrity and safety during the use period. If the gypsum relief decoration product is too thin, it will not only have a short service life, but also affect safety.

Gypsum line is the decoration material of the house, the main interior decoration. It can be brought with a variety of patterns, practical and beautiful. It has the functions of fireproof, moisture-proof, heat preservation, sound insulation, heat insulation, and can play a luxurious decorative effect.

Gypsum is an airtight cementitious material, and gypsum relief decorative products must have a corresponding thickness to ensure that their intermolecular affinity reaches the best degree. So as to ensure a certain service life and integrity and safety during the use period. If the gypsum relief decoration product is too thin, it will not only have a short service life, but also affect safety.

Generally, the concave and convex patterns of gypsum relief decorative products should be more than 10mm, and the production is fine. In this way, after the installation is completed, the surface can still maintain a three-dimensional effect and reflect the decorative effect. If the pattern pattern of the gypsum relief decoration product is shallow, only about 5 9mm, the effect will be much worse.

Gypsum line repair first with high-grade gypsum powder to add gypsum line special adhesive glue, stir evenly, in the use of shovel paste, according to the gypsum line meridians to "carve", and so on a little hardness, and then brush water, but for the decoration of the gypsum wall repair is not everyone can do. Secondly, if the color of the plaster line is not satisfied, it can be refreshed with paint.

Gypsum lines turn yellow after brushing latex paint, which is a process problem during construction. If the putty is not approved according to the construction process, the putty will be batched two or three times before the first batch of putty is completed, which will quickly make the color seep out, if the primer and topcoat are brushed, the time is too short, and the paint is not completed, this situation will occur, because the paint used is water-based paint, and the color will seep out with the water, so this situation will occur.

1.If it is a part, then there is only one reason why the plaster line is contaminated. That part was either degummed with tape or contaminated with Styrofoam.

If the whole root is yellow, it should be a problem with the worker's construction. The latex paint is too thin when he paints the plastering line, which will also cause the overall effect to be not as good as the wall color. Don't think about paint because even the worst paint will be brushed through.

Many manufacturers bleached the eraser to a colorless color when making plates. When the hardener of the polyester white paint reacts with the oxidizing substances in the bleach, the wall turns yellow. In general, yellowing of paint is difficult to deal with, and most of it needs to be refurbished.

But after refurbishment, there are a few things we can use cleverly to prevent the paint from turning yellow.

2.Stick plaster lines to the wall first, then stick them tightly. After painting, not only is it not solid, but it is easy to stain the wall.

Because it is good to brush latex paint after plastering the plastering line, and then brush the latex paint after pasting the plastering line, it looks good and strong. The bottom layer above the plastering line is not well treated, and the latex paint is too thick. Before the latex paint is rolled, the rolling surface should be dry, and the adhesion of the latex paint rolled on the wet surface is degraded by moisture, which will lead to peeling.

3.Because of the reflection of light, etc., the color of the walls of the room will look darker than the color card after the four walls of the room are painted. The color that consumers see on the color card is often different from the actual color of the paint on the wall.

Choose the color number you prefer to be slightly lighter. If you prefer a dark wall, you can adjust it according to the color of the chosen color swatch. The above is the answer to the question of how the plaster lines turn yellow after applying latex paint.

The reason why the gypsum lines turn yellow after brushing latex is because of which material will directly cause some chemical reactions, so it leads to changes, or it may be because the process is not good when making it, so the reason for the yellowing may be because of the poor quality of the latex paint used, or the poor quality of the gypsum lines.

This may be because the gypsum line has a series of oxidation reactions after brushing the latex paint, the gypsum line did not open the packaging bag when the net was played, and there was an over-drying situation, and the putty was not batched according to certain requirements before the latex paint was brushed.

It may be caused by a process problem during construction, or it may be caused by a problem with the material.

Clean up the original putty powder in the place where you plan to paste the gypsum line (the corner of the top surface), apply water with a roller and shovel it off with a shovel, so as to prevent the installed gypsum line from falling off soon.

If the height is not known, you can use a small line to draw it on the top corner, and then measure the length of the wall, use a hacksaw or a knife to see the total length of the gypsum line, figure out the top and bottom of the gypsum line, stand up and stand up the gypsum line, saw both ends at a 45-degree angle, mix the gypsum powder with water, not too much, otherwise it will be hard to fall, evenly scrape on both sides of the gypsum line, and then two people hold up the ink line position on the wall on the edge of the gypsum line, and hold it down 3 In 5 minutes, the unsealed part of the joint can be mixed with gypsum powder to level it.

After the gypsum line is pasted, the painter repairs the joint part of the gypsum line again to achieve the fading of the joint part, so that it is difficult to find, and then repairs the top surface of the wall to ensure that the width of the gypsum line out of the wall is consistent.

Brush latex paint, and the top surface is required to use the same kind of latex paint of the same color, generally a primer and a topcoat. As long as the gypsum line added after construction is strictly in accordance with the construction process, cracking and falling off can be basically avoided.

It can be installed, I also installed it after brushing it before, and there is no problem, and it has been a few years, and there is no condition.

A firmer approach is not to paint the part of the plaster line and paint it after it is installed.

It's perfectly fine, except that you don't apply the adhesive material to the wall when fixing the plaster line.

If it's uneven, there will be gaps, and you have to brush it again after installing the plaster line, otherwise it will be ugly.

Yes, he told you that it was wrong to hang up, and the purpose was to make you money.

Hello, I see that you have installed it, how did you install it? I also applied latex paint first.

If the peeling is generally because of moisture, if you do not completely solve the source of moisture, do a good job of waterproof and moisture-proof treatment, it will make the latex paint fall off after a long time, if there is no moisture, you need to re-make the gypsum line into putty, because the putty itself will have the function of moisture absorption, and then wait for it to dry thoroughly, and then smooth it with fine sandpaper, and then brush the latex paint.

Before the construction of latex paint, all the shells and cracks on the wall should be removed, and the filler should be used to fill the level, remove all the residual slurry, garbage and oil stains on the wall, and the large area of the external wall should be treated separately. Sanding out the uneven areas and rough surfaces, then rinse the walls and paint them when they are completely dry.

Before using the roller, you must first use a brush to apply the parts that the roller cannot reach, and wait for 2 to 3 hours before rolling a large area with the roller. The drum should be of high quality. Apply primer first during construction, and wait for about 6 hours for the primer to dry completely before covering the topcoat.

Make sure that the place where the latex paint is painted is completely dry. Peeling is generally because of moisture, if you don't completely solve the source of moisture, do a good job of waterproof and moisture-proof treatment, it will make the latex paint fall off after a long time. If there is no dampness, you need to re-putty on the plaster line, because the putty itself will have the function of moisture absorption, and then wait until it is dry, then smooth it with fine sandpaper, and then brush the latex paint, basically there will be no problem.

The base layer is not dry, because the gypsum line is wet or dirty when painting, resulting in poor adhesion of latex paint, and it will peel.

If it is caused by moisture, dry it and shovel off the loose ones and reapply them.

If it is dirty, wipe it clean and reapply.

The first point is that the plaster line is not cleaned, and the polishing is smooth, so it will rise. Second, if you can't hang the paint on the plaster line, you can lightly layer putty.

It is recommended to replace the gypsum line directly when overhauling in the future, which should be a quality problem of the gypsum line.

Can you still stick to the wall cloth after brushing latex paint?

Whether the wall can be pasted with wall cloth after being painted with latex paint depends on the specific situation of the wall.

1. Whether the wall can be pasted with wall cloth detection method.

After compacting and pressing the wide tape on the latex painted wall, lift it vertically with the wide tape and observe the condition of the wide tape.

1) If the adhesive surface of the tape is relatively clean, you can directly brush a layer of wall base on the wall, and then paste the wallpaper.

2) If there is a little latex paint on the tape, you can first brush a layer of wall base on the wall to enhance the solidity of the latex paint layer and putty layer. Once the film has dried from the bottom of the permeable wall, brush the wall base again.

3) If there is a large piece of latex paint on the tape, then you need to clean the latex paint layer on the wall before you can paste the wallcovering.

2. The traditional method of brushing latex paint on the wall cloth is to directly apply the penetrating base film or other base film directly to the latex paint wall, and then paste the wall covering.

Beautiful latex paint is also very good for surface decoration, but people want to scrape putty directly on the wall, which is also needed for trembling.

Can latex paint walls be scraped with putty directly?

You must know that the wall of latex paint in the early stage is also very beautiful, but you can't scrape putty directly, otherwise it will affect the effect of decoration. It is also not good for decoration.

It is best to remove the old wall first, and then remove the putty and paint. You can use an abrasive cloth to wipe the latex paint off the walls, then rub the putty and then apply the latex paint.

Latex paint is the common name of latex paint, latex paint wall can be scraped putty can be directly latex paint is a kind of synthetic good material represented by acrylic copolymer emulsion, liquid binder, filler is a variety of additives that are refined by grinding and dispersing coatings. Compared with traditional wall paints, latex paint has many advantages, such as brushing, latex paint wall can be scraped directly putty to dry quickly, water resistant and scrub resistant.

The essentials of buying latex paint.

Look at the appearance. Eco-friendly latex paint should come with a product, so make sure you have it when buying a product. A common latex paint brand now includes an environmental test report or test sheet. When making an enterprise environmental test report.

To check the weight and quality of the latex paint, weigh the weight and listen to the sound. Green latex 5 liter bucket is about 7kg. Barrels of 18 liters are about 25kg, and if they are heavy, weigh them so that they can be recorded there.

It is also necessary to lightly apply the sound of the paint bucket shaking to the green latex and then shake the sound of them if the paint proves to be insufficiently viscous next time.

Practical checksIf you can open the jar, you should check the latex paint for viscosity, odor, fluidity and adhesion. After the sticker exceeds a certain amount of agglomerate in the normal green latex, the odor, latex, or quality issues can also touch a small amount of fingers after stirring the paint bucket. Explain what is emulsion liquid and what is soft, delicate to the touch, good paint fineness, a little dry, otherwise clean moisture, such as clean fingers, good adhesion, poor adhesion.

When the latex paint wall is renovated, the construction should not be sloppy.
