After spraying latex paint for about 4 hours, the shape is yellowed What is the reason?

There could be two reasons for this.

1. The putty layer is not done well, the thickness is different, so that the refraction of the light on it is different, and when you look at it at different angles or directions, you will feel a little "yellowish", but the intensity of the reflected light is different.

2. Latex paint is not done well, which can have 2 situations:

1) The latex brush is uneven, and the thickness is different in some places, resulting in different light reflections, which is the same as putty, but much more obvious than putty.

2) The latex paint is unevenly blended, and the latex paint has a sequence in the process of painting, because the latex paint is a water-based material, which is easy to oxidize with the air, and it will change after a long time, so it is easy to start yellowing first, if your latex paint is not done in a time period, this situation may occur. And after the latex paint is done, there will always be some tinkering, so generally experienced construction will separate the second and third latex paint, and the last time to be repaired, so that the probability of "yellowing" will be greatly reduced.

The general treatment is to brush it again, if you have the original latex paint, and the interval is not long, if not, according to the current color darker, try to match the color in a room.

Drywall and wall anti-alkali! The main reason for this problem is the inexperience of the workers! Brushing latex paint when the white is not completely dry can also be caused by rainy day work!

But don't worry, it can be remedied, wait a few days for Dabai to be completely dry, just brush the latex paint Your big white worker may be a novice!!

This question and the master who scrapes the white.

There is an indirect relationship.

The reason for the yellowing of the shape is that the materials chosen by the carpenter master during decoration are not appropriate.

The master of Dabai did not deal with the underlying treatment of the modeling material, resulting in the yellowing.

How to deal with it: Wait until it dries, brush the latex paint 1 to 2 times, the effect will be better for the time being, and it will come back after a long time.

It's going to be troublesome to do it again, forget it.

Summary. Dear, hello, after spraying latex paint, the next day yellowing Latex paint is a water-based paint, easy to be oxidized by air, and will change for a long time, of which the first painting begins to turn yellow, so there must be construction when painting. If latex paint is not applied at the same time, yellowing of the walls will occur.

After applying latex paint, it is inevitable that some areas will have to be repaired, so incorrect repairs can also cause the walls to turn yellow. When repairing, the first and second coats of latex paint should be brushed separately, then repaired, and finally brushed again. The reason why the walls turn yellow just after painting latex paint is that some walls have water leaks, but when the water is completely drained, they are not directly covered with latex paint.

In this case, the surface of the wall will turn yellow. <>

Summary. Hello, there are several reasons for the appearance of yellow dots. First, the alkali content of the cement wall is high; 2. The alkali content of gray calcium powder or cement in putty powder is high; 3. The emulsion contained in the wall solid itself has poor water resistance, and the alkali in the cement or putty is precipitated.

After brushing the latex paint and drying, yellow spots come out, what's going on?

Summary. Yellowing the next day after spraying latex paint: The yellowing after brushing latex paint may be caused by the lack of priming treatment or the poor quality of the primer paint. Because there is no putty according to the construction process during construction.

Yellowing the next day after spraying latex paint: the yellowing after the removal of latex paint may be caused by the lack of priming treatment or the poor quality of the primer paint. Because there was no brigade during the construction, the bridge had to be approved according to the construction process.

The yin corners are yellow, and the walls are not yellow.

The installed yin and yang angles need to be flat and perpendicular to the punch bar. Wait for the yin and yang angles to be installed and dry, and then the wall can be leveled.

Yes, the wire box switch turns yellow.

Is it the case for all walls to be like this, or is this the case locally? Under normal circumstances, because the developer has not done a good job in the waterproofing of the kitchen and bathroom, it is easy to appear on the wall outside the kitchen and bathroom, and there are several other situations that will occur The phenomenon you said, the first is the dampness of the building itself, the second is the seepage of the outer wall, the third is the leakage of the pipes in the wall, and the fourth is the storage of water on the terrace, but no matter what the situation, it is the water to blame! Rulers.

It depends on the size and depth of the trunking, if it is relatively large, the gypsum will be more batched, and its drying time will be longer; After the plaster is approved, after it dries, the putty will be batched; The putty is batched twice, and then (after drying) it should be smoothed with a sand peel. In this way, you can brush latex paint, generally twice. The interval between the two passes is generally 2-3 hours.

One thing you should note is that the new latex paint is not the same color as the original, so you may need to paint the entire wall. In doing so, it will look like a color.

Look at whether the plaster that has been approved is firm, if it is firm, there is no need to remove the plaster, the key is to be dry.

The Monkey Island External Propaganda Group will answer your questions in a low-key manner.

The wall, first ensure that the wall is not seepage, then scrape the porcelain powder to make the base, and then brush the latex paint, you are estimated to be seepage, or smoked.

The ground floor is not drying out or the walls are damp.

Yellowing means that the wall is damp, or the putty layer has not dried out and the latex paint has been brushed, and now you can only wait until the wall is dry before rolling the latex paint, and you can't continue to brush the latex paint before.

Just brushed, if you just brush, it is normal if it is not dry, and it will not turn yellow if it is completely dry after ventilation for a week or two, and it is recommended to use brand latex paint such as Nippon, Dulux, China Resources, and red apple paint.

Do you mean that the resurgence of moisture and yellowing is this the case on all walls, or is this the case partial? In general, because the developer has not done a good job of waterproofing the inside of the kitchen and bathroom, it is easy to appear on the wall outside the kitchen and bathroom, and there are several other situations that will occur The phenomenon you said, the first is that the building itself is damp, the second is the external wall seepage, the third is the leakage of the pipes in the wall, and the fourth is the storage of water on the terrace, but no matter what the situation, it is the water to blame! Different situations are handled differently!
