If the house leaks and turns yellow, you can directly apply latex paint to cover the yellowed part

Cover the yellowed part.

First, investigate the cause of the water leakage at the most serious location and analyze what the specific cause of the water leakage is.

1. Water leakage on the exterior wall. Then you have to find the property to solve the problem, because the exterior wall leakage is very troublesome to repair.

2. If the bathroom, kitchen, and balcony leak, that is, the waterproof is not done well, then the floor tiles should be placed.

Or a bathroom caisson.

Demolish, re-leveling to do waterproofing, and then tiling, try to be careful when tiling, do not scrape off the waterproof layer, and you need to pay attention to the waterproof interface position of the ground and the wall, try to brush up, don't just brush the ground.

3. If the water pipe is leaking, then find out where the water pipe is broken, and find out the as-built drawings of the hydropower laying at the beginning.

Find out the direction of the water pipe, then check the leakage location, remove the small area of floor tiles, and then repair the water pipes again, water pressure test, if there is no problem, then you can re-lay the bricks. (Note that it is best to have extra floor tiles, if it is not recommended to look at the bigger ones, otherwise it is difficult to repair one or two pieces).

In short, according to the actual cause of water leakage, whether it is because of waterproof problems or water pipe seepage problems, the specific problems are analyzed in detail, and then the repair plan is determined, do not do it blindly.

If this problem occurs, you must wait for the wall to dry before you can deal with it. Because the sewage has invaded the inside of the wall, and the wall has the function of "breathing", it will bring out the sewage in the wall at any time with the indoor air dry and wet exchange. Putty and latex paints are also not like PVC, which will leak out the sewage in the wall.

No matter how good the latex paint you paint, its material properties are the same.

Rectification method: remove the putty and latex paint, and then scrape the putty and brush the latex paint again after the wall is dry. Otherwise, the final result will still be yellow, and the effort will be futile.

This method is not long-lasting, easy to leak down, you need to brush the surface clean, sandpaper sanding and then brushing, the effect is better

The yellowing of the wall is generally the deterioration of the base layer, which makes the wall appear "color return". If it is a sand-plaster wall, you can first brush a layer of white cement slurry on the wall, and then batch the ash, polish and paint. If it is a wooden laminate, you can brush a layer of white paint on the surface, then batch the ash, sand, and paint.

The reason is that it is very likely that it will come out after brushing the paint, because the bottom of the putty has a greater effect, and the latex paint has a covering power, but it is not very strong, it is best to check what is the reason for the yellowing now. If the wall is too wet or alkaline, it must be treated first, otherwise the latex paint will not be covered. Since the workers feel that it is alkaline, they have to discuss the anti-alkali treatment.

However, I once saw a construction site because of putty, in short, after the study is clear, let's brush latex paint. You can shovel the putty and look at the original wall.

One reason is the construction of the base putty powder or large white powder mixed with white glue cellulose instead of putty powder, the quality of the base material is not good, and the other may be the smoke of the house in the construction process for a long time or the smoke of burning coal for heating adhered to the hemp sand wall, if it is because of the base material, it is necessary to shovel off and redo, if it is smoked, it is necessary to shovel off the coating and brush the interface agent again.

Answer hello I have received your question I will reply in time after reading Please wait patiently 1. Among the mixed pigments of the selected compound color paint, the specific gravity of various pigments varies greatly, resulting in a floating color of latex paint, and finally a yellowing phenomenon on the wall. The solution is to add some anti-floating agents in the process of production and construction of multicolor coatings with large differences in the relative density of pigments. Personally, I recommend that you do not mix colors on the spot, because many times after the on-site color mixing, there will be uneven colors and yellowing somewhere on the wall.

2. The construction process and construction technique are wrong, resulting in the yellowing of the latex paint wall. The most common reason is that the bristles used are too thick and too hard. Or before using the paint, the precipitated color is not stirred evenly, and it is painted on the wall.

The solution is to use some pigments containing relatively high density, and it is best to use a soft-bristled brush when painting; Another point is to stir frequently before painting, and then paint after stirring evenly. 3. The choice of latex paint primer is wrong. Generally speaking, latex paints are two different types of paints.

One is primer, also known as sealing primer; The other is the topcoat. Before painting two layers of area, it is necessary to apply a layer of sealing primer, and this layer of sealing primer must be an alkali-resistant sealing primer. The solution is to remove the latex paint on the latex paint wall and clean it, apply the alkali-resistant sealing primer, and then apply the latex paint topcoat twice after the primer is dry.

4. Factors of the construction environment. The main influencing factor is that the indoor humidity is too high, and the wall has condensation and moisture return. Generally, when emulsion paint is constructed, there is an indoor humidity requirement.

If the humidity is excessive, dehumidification measures must be taken. Otherwise, the wall may contain too much moisture, resulting in the return of moisture, and finally the yellowing of the wall latex paint. The solution is to repaint the yellowed latex paint on the wall.

The yellow substance on the seepage wall is a water-based substance, and after applying water-based paint, this yellow substance will continue to seep out, resulting in the phenomenon that it cannot be covered. Nippon Paint Refresh Service specializes in wall renovation, and it can also be handed over to them to solve.

For water-seeping and yellowed walls, the first thing to look at is the problem, rather than choosing whose latex paint can be done.

If it is water seepage from the wall, any latex paint will be useless.

1: Do a good job of waterproofing the exterior wall first. The test is completely watertight before proceeding to the second step.

2: Sand, or re-scrape a layer of latex paint putty powder.

3: Re-roll or spray latex paint, completely ** the problem.

Otherwise, it's useless.

In your case, you have to hang out all the putty and latex, and then re-apply the latex paint to that piece of putty.

It is recommended to brush a layer of wall solidification first, which is equivalent to a primer, and the top paint is white.

Latex paint is widely used in home decoration, and its delicate texture and rich colors are deeply loved by people. However, if the wall is watery or yellowing, it will not only affect the aesthetics of the interior, but may also have a negative impact on the living environment. Here are a few common ways to deal with it for your reference:

1.In order to solve the problem of water seepage on the wall, it is first necessary to find the cause of water seepage, such as wall cracks, leaking pipes, etc. The treatment method varies according to the specific situation, and can be solved by plugging the crack and strengthening the waterproof layer.

2.Walls that have already yellowed can be cleaned with professional bleach or reapplied with new latex paint. It is recommended to choose non-toxic and odorless natural latex paint, which can effectively protect the living environment and human health.

3.Before renovating, it is recommended to choose high-quality latex paint products and apply primers and topcoats in the workshop. This guarantees the quality and color uniformity of the wall.

4.When the air humidity in the living environment is too high, it is also easy to cause water seepage and yellowing on the wall. In this case, it is necessary to increase ventilation or use tools such as dehumidifiers to adjust the humidity in the room.

In short, in view of the yellowing problem of the noisy cover of the latex paint wall seepage bridge, it is recommended to take effective treatment measures in time. At the same time, the management and maintenance of the indoor environment should also be strengthened to ensure the comfort and health of the living environment.

The first thing is to find the water seepage point of the wall and the cracks of the external wall, and sweep away the external wall plastering layer, wall cracking plastering layer and large-scale cracks of the external wall at the interface between the gas and the structural beam along the cracks. Then find out the money should be hand-held cutting machine to cut the plastering layer to prevent the plastering layer from being generated by vibration when the plastering layer is out early. This is how to deal with water seepage from the walls.

Wall seepage treatment method: the wall material should be selected with high density and high strength; After the installation of the water supply and drainage pipes, the water is tested, and the wall decoration is carried out only after the water leakage is confirmed; Carry out construction in strict accordance with the construction specifications, and do a good job of waterproofing the exterior wall. The interior wall is scraped and redone, and the waterproof putty is scraped and applied, and the waterproof paint on 1 bottom and 2 sides is painted after grinding and leveling.

Causes of yellowing of the wall:

1) The alkalinity value of the original base layer is high, resulting in alkali return to the wall, and the alkalinity of latex paint and alkalinity is high.

2) Smoking, smoking, and oil fumes.

Wall yellowing treatment method: It is recommended to cover the whole skin, and the extra yellow needs to be removed.

Treatment of the leakage wall of the house:

1. Clean it with sandpaper first, try to be as smooth as possible, and then paint. Looking at the economic situation, every time I rented a house, I used to buy my own paint and paint the places I couldn't stand it, because I felt that no matter whether I was married or not, I liked the feeling of home, clean, bright, warm and vibrant.

2. If it is your own house, make it better, environmentally friendly paint or scrape porcelain. My house is also leaking, and I have to make up for it. I'm a girl, and it's very rewarding to do something like this on my own.

First of all, clean the yellowing and seepage of the wall, and then use a small shovel to shovel it off until the plastering layer is exposed; Then fill the gap with cement ash again, noting that it needs to be carefully filled in with a shovel; Then make a waterproof layer, and carefully spread the waterproof material to the cement ash with a scraper; Scrape putty at the end.

The quality of latex paint is not up to par, or the sealing primer is not up to par It is recommended that you choose something with water resistance! In this way, it will not turn yellow when it comes into contact with water.
