What should I do if the latex paint has a watermark? The latex paint is all printed after brushing,

First of all, thank you for being invited to answer the question.

The subject's question is a bit unclear, I don't know if it's latex paint.

There is a problem with the quality itself, or there is a watermark after the latex paint is on the wall. If it is the former, there is no other way than to find the merchant to return the goods or complain to the relevant quality authorities.

However, if a watermark appears after the latex paint is applied to the wall, it may be the following two situations:

1. The wall painting construction is not implemented in accordance with the technical requirements.

This situation mostly occurs before the first time the wall is primed with putty, that is, before the initial original lime sand layer wall coating construction, in some areas, especially in the south, the wall is easy to absorb water and moisture in the humid rainy weather, if you do not wait for the wall base to dry at this time, you will directly cover the primer construction, the moisture will be directly sealed under the paint, once the wall water vapor begins to volatilize, the most direct consequence is that the water vapor appears through the pores of the paint back to the bottom, which is what we often call the watermark.

If this situation occurs, the most common solution is to use a heat fan to heat the watermark part to accelerate the volatilization of water vapor contained in the wall, but the effect is not very obvious, and the long-term high heat will also damage the paint on the wall.

2. Caused by long-term water leakage upstairs.

This situation is common in upstairs bathrooms or other water-walking areas where water leaks and seeps, and the wall finally exceeds the moisture content of the wall due to continuous water injection.

There will be a phenomenon of penetration.

This kind of phenomenon is relatively easy to solve, and the less destructive way is to let it dry naturally or use heating equipment to accelerate the volatilization of water, but not to remove the watermark.

If you want to cure the symptoms, you can only remove all the wall paint of the water-bearing part of the wall, expose the original wall base, and then wait for a period of time for it to dry naturally, and then use the primer to seal the wall base and carry out the wall paint construction again.

Of course, no matter which method or measure is taken, the leakage part of the upstairs must be treated first, which is the premise of subsequent construction.

Therefore, if there is a watermark on the wall latex paint, first of all, it is necessary to find the reason to deal with the symptomatic construction, no matter what, if the wall once the watermark appears, it is not a single way to take the drying method can be solved, because the volatilization of wall moisture takes time, if the watermark phenomenon is serious, it may dry for a longer time, the safest and safest way is to ensure that the wall base is dry before the initial wall construction, if the wall is damp, do not rush to the construction, After waiting for the water to evaporate and the wall is completely dry, there will be no trouble of reworking these walls in the future.

First of all, there are several situations:

It is normal for latex paint to be inconsistent in color when it is not dry, and there will be no traces after it dries.

If there is a watermark after the decoration, there are two situations, one is that too much water affects the hiding power of the latex paint, and there is the impact of the environment, such as the watermark on the wall in long-term rainy weather.

In such a situation, we can carry out the rolling brush on the original basis, and when choosing the five questions, we must choose the best one, otherwise it will also affect the later decoration. And pay attention to ventilation.

Thanks for having me! 1. In the case of not yet drying, the inconsistency of color should be normal, and there will be no traces after drying.

2. Before brushing latex paint, the putty layer is not partially dry.

3. There is a problem with the quality of latex paint, or it is mixed with too much water, which affects the covering power of latex paint.

If it is the first type, it can be heated indoors or dried by blowing. In the third case, you need to remove the watermark and then repaint the latex paint wall.

Latex paintThere are brush marks for three reasons: the paint dries quickly, the viscosity of the paint itself is too great, and the wall surface is not clean.

Because latex paint coatings are diluted with water, the paint has a natural leveling on the surface of the substrate. Of course, this process will take some time to complete. At room temperature, after the original paint contains 20% water, after brushing, the whole process will be completed in a few hours, forming a dense paint film.

If the paint has not been leveled according to the initial 20% water exchange rate, the water paint will evaporate at high temperatures, the paint on the walls will naturally thicken, and then the brush will inevitably develop brush marks.

Precautions for brushing latex paint.

1. In order to prevent the floor from getting dirty before brushing latex paint, you can lay a barrier on the ground, or some waste newspapers, plastic sheets and unused clothes.

2. If there is a place that does not need to be painted with latex paint, a barrier needs to be attached to prevent it from being soiled when applying latex paint.

3. If the latex paint has not been used up and the can has been opened, then it needs to be sealed tightly, in order to avoid its surface crusting and falling into the bottom of the can, it can be stored upside down, so that it will be more convenient to use.

There is a watermark.

There are generally two reasons for the watermark on the roof of the residential ** analysis: one is water leakage, and the other is moisture return, which needs to be checked according to the specific situation. If the watermark appears after the decoration of the new house or in the south of the south, it is likely to be caused by the return of moisture, and it is necessary to use dehumidifiers, air conditioners and other electrical appliances to reduce the water vapor content in the air to prevent the watermark from mildew.

If it is caused by water leakage in the upstairs pipe or water seepage on the exterior wall, the watermark will continue to expand around the leakage point.

Reduces the water vapor content in the air; After closing the doors and windows, use dehumidifiers, air conditioners and other electrical appliances to remove the moisture in the room, and wait for the cement mortar to dry completely before painting.

There are two reasons for watermarks on the roof to re-damp.

First, the water seepage in the cement mortar; After the decoration of the new house, if the cement mortar on the roof or wall is leveled and the primer and paint are directly applied without completely drying, the moisture in the cement mortar will slowly seep out in the later stage, resulting in a watermark on the roof.

second, a large amount of water vapor in the air is caused by condensation; When there is a large difference between indoor and outdoor temperatures, the water vapor in the air will condense into water droplets in the house, soaking the roof and walls and creating watermarks. This usually happens in the south during the rainy season.

Summary. Can be shoveled and redone. If the latex paint wall seeps water, usually the wall will become yellowish after the water is dry, and it will affect the appearance, so when the wall seeps, the wall must be removed, and then the original putty and gypsum line are also removed, and the new latex paint wall is remade.

If there is a leak due to the water pipe embedded in the wall, you need to knock the wall open and replace the water pipe with a new one to ensure that there is no water seepage, then repair the wall, and then redo the wall according to the complete steps. When redoing the wall, you can use some waterproof putty, which can have a certain waterproof effect.

It's fine. Can you do it.

It's not oozing, is it?

No. I just accidentally spilled it.

If it is seeping water, it is best to shovel it out and do it again.

That's not a big problem with the <>

Is it good to air dry naturally?

Well, it's good to dry naturally, you must be careful next time, try not to splash water on the latex paint just brushed<> although the current latex paint is said to be waterproof, but it can't be completely prevented, especially we just know that the decoration try not to touch the water, like Si Jian This is good to open the pants and dry a little naturally, next time you must pay attention.

Summary. Hello dear, what should I do if there is a watermark after the latex paint is wiped with water: 1. Natural air drying:

The wall painted with latex paint has a watermark and cannot be constructed immediately, and the watermark needs to be removed, so you can choose the way of natural air drying, but it takes a long time, and it is suitable for a large range of watermarks, but it is not very obvious. 2. Artificial drying: If the watermark phenomenon is serious, you can use electric fans, hair dryers and other equipment to accelerate drying, and apply a layer of primer to the watermark area to seal the wall substrate after drying, so as to avoid the problem of dampness in the later stage.

The wall has a watermark can not be used for latex paint construction, which will affect the drying effect and adhesive effect of latex paint, and it is easy to have problems such as hollowing, cracking, and falling off in the later stage, so it is necessary to ensure that the wall is completely dry before brushing latex paint.

2. Artificial drying: If the watermark phenomenon is serious, you can use electric fans, hair dryers and other equipment to speed up the drying, and apply a layer of primer to the watermark area to seal the wall substrate after drying, so as to avoid the problem of damp withering in the later stage. The wall Suihui has a watermark can not be used for latex paint construction, which will affect the drying effect and adhesive effect of latex paint, and it is very easy to have problems such as hollowing, cracking, and falling off in the later stage, so it is necessary to ensure that the wall is completely dry before brushing latex paint.

What's going on with the watermark on the wall painted with latex paint: 1. The putty layer is not partially dry. The wall of latex paint should be leveled with greasy closed ruler powder first, that is, the putty layer should be painted on the wall first, which can not only make the wall smooth and smooth, but also increase the adhesion of latex paint to ensure the construction effect.

If the thickness of the putty layer is uneven, there will be an inconsistent degree of drying, so that most of the areas are dry, and some are not dry, and these areas will show watermarks. 2. If the wall encounters water and brushes the latex paint wall, if there is water seepage, water and other situations, it will show the watermark on the wall, these watermarks are obvious, if it is not treated in time, it will affect the adhesion effect and hiding power of latex paint, etc. If it is only in contact with water, it can be air-dried, but if there is water seepage, it will be more troublesome to deal with, and it needs to be repaired and waterproof measures should be taken.

Latex paint is a commonly used wall decoration paint, but watermarks often appear when painting, which has a great impact on the appearance. Based on years of decoration experience and case analysis, the following summarizes the methods to solve the problem of latex paint scraping the wall with watermarks for your reference.

1. The reason for the watermark.

There is a watermark on the wall scraped by latex paint, which is generally caused by a variety of factors, such as environmental factors such as temperature and humidity on the wall itself, or the old wall is not properly treated before painting, and the primer is not painted.

2. Solution.

1) Use a professional stain remover. For the main watermarks, you can use a stain remover that specifically removes oil stains and watermarks on the wall. To use, apply the stain remover to the watermark-contaminated area, wait for 15-20 minutes, then wipe it with a clean, damp cloth, and then use an absorbent dry towel to dry the water on the wall.

2) Wipe with a hot towel. If the watermark on the wall is mild, you can wring it out with a damp towel soaked in hot water and gently wipe it on the contaminated area, but be careful not to use excessive force to avoid damaging the wall paint.

3) Repaint. If neither of the above methods can effectively remove the watermark on the wall, you can only repaint it. Before painting, the old wall needs to be thoroughly cleaned to remove dirt, oil, etc. from the wall, and then primed with a special primer before formal painting.

3. Precautionary measures.

1) Treat the wall in advance. Before painting, the old wall should be treated as necessary, and the stains and oil stains should be fully cleaned to ensure the cleanliness and smoothness of the base layer, so as to effectively avoid the generation of watermarks.

2) Choose high-quality paints. Choosing a latex paint with strong water resistance can effectively avoid watermarks, mildew and other phenomena caused by long-term moisture.

3) Properly control the indoor temperature and humidity. Keeping the indoor temperature and humidity appropriate to avoid the impact of undesirable environments such as excessive temperature and humidity on the wall is also an effective measure to prevent watermarks.

In short, in view of the problem of watermarks on the wall scraped by latex paint, it is necessary to comprehensively analyze the causes of the original distress and select appropriate treatment methods to avoid affecting the appearance of the house and keep the room clean, hygienic and comfortable. At the same time, in the usual daily maintenance, we should also strengthen the cleaning and maintenance of the wall, and find and solve problems in time.

Summary. 1.Clean the surface:

Use a damp cloth or sponge to clean the surface to remove dirt and dirt. 2.Remove water stains:

Use a clean sponge or cloth dampened with a small amount of white vinegar or alcohol and gently wipe the water stain until the water stain is completely gone. 3.Dry surface:

Wait for the surface to dry completely, which usually takes a few hours. 4.Painted with latex paint:

Use latex paint of the same color as the original wall and apply it to the wall until the coating is even. 5.Repeat the brush:

If desired, a second coat of latex paint can be applied to ensure that the wall is evenly colored. 6.Wait for drying:

Wait for the latex paint to dry completely, which usually takes 24 hours.

Notes:1Do not use too much vinegar or alcohol to avoid damaging the source mill wall.

2.Make sure the surface is completely dry before applying the latex paint to the cracks. 3.

If the water stain mark is very stubborn, you can use a cleaning agent from the Inspectorate or have a professional handle it.

The water jumped on the wall, and now there are a lot of marks, and I want to know how to get rid of it, and the walls of my house are pearl white.

You can try the following methods to remove the watermark:1Use a mild detergent and a damp cloth to gently wipe the watermark, then dry with a clean, damp cloth.

2.Mix the white vinegar with water, then dip a damp cloth into the mixture, gently wipe the watermark, and finally dry with a clean, damp cloth. 3.

Use toothpaste or soapy water to gently wipe the watermark and dry it with a clean, damp cloth. 4.If none of the above methods work, you can consider using a professional wall mask cleaner or ask a professional cleaning company to clean it.
