If the original paint is relatively intact, it does not need to be removed, you can do a simple sanding and then use latex paint.

It is completely possible to repaint directly on it; The owner believes that there is no need to eradicate: for many old houses when they want to repaint the wall with latex paint, the master suggests that the paint on the original wall should be removed.

The old house has to be painted with latex paint, and the original walls are quite complete, so it is said that the original walls should be painted? When encountering problems, they can be analyzed and understood according to the following three methods, so as to make corresponding decisions. If you want to repaint the old house, the original wall condition will directly affect how to do it, and the most significant thing is whether the paint on the original wall should be removed.

The walls of the old house were painted with latex paint, and the original walls had the following conditions, that is, they "needed" to be removed. There were a lot of cracks in the original walls, and if the building had been living here for a long time, there were big cracks in various parts of the walls, and if you wanted to paint it again, you would have to remove all the paint from the original walls.

The original wall will become wet, if there are a lot of water stains on the original wall, it means that whether it is done well or not, it will cause great damage to the wall, and at this time, it is necessary to remove all the paint on the original wall to paint it again. There are stains on the original walls, old houses, due to daily use, there are often some stains on the walls, or children use brushes to graffiti on the walls, in this case, to apply latex paint on the old walls, you need to remove the paint from the original walls.

The walls of the old house should be painted with latex paint, and the original walls have the following conditions, that is, "do not need" to be demolished, the original walls are intact, for a careful person, even if they have lived at home for several years, there will be no problems such as damage, water leakage, stains, etc., if it is only fading because of natural reasons, then it does not need to be repainted, but can be repainted.

The landlord did not feel the need to tear it down, and when many old houses were to be painted, their master would remove the paint from the original walls and apply a layer of latex, but if this was the case, they would not have to paint the original walls, but instead of painting the original walls, they would paint the original walls with a new layer of latex.

The old house is painted with latex paint.

When the paint on the original wall is relatively intact, do you still need to remove the paint on the original wall? Can you paint old walls directly? The original wall foundation at home has good strength, and it is a latex paint wall, so you don't need to shovel off the wall skin, you can directly paint it with simple sanding, cleaning and repair.

It should be noted that the integrity of the original wall paint film should not be damaged, and latex paint with better adhesion should not be used, otherwise the wall will easily peel off.

<> the old wall at home is melamine, if you want to repaint, you need to scrape off the old wall skin or paint the wall, and then repaint putty powder.

It can only be painted after polishing. Do not cover the dark paint with light paint, brush the wall with white paint beforehand, and wait for the paint on the wall to dry white.

After that, you can paint the color paint again. If the domestic economic conditions allow, it is recommended to do it again. If you buy a wall that has not been renovated for a long time, then when dealing with the wall, it is possible to keep the original wall and not completely shovel it, so that the owner can use a steel brush, sandpaper or grinder to polish the wall, and then brush the latex paint.

For shoveling wall paint, you only need to shovel to the cement layer, if the cement layer is pulverized, cracked, and peeled off, you need to shovel out the red bricks and finally repaint the wall. See if there are any large-scale cracks or "cracks" on the wall. You can try to dig a hole in the wall with nails, because the loose layer of sand in the wall can dig out the sand, so it is necessary to shovel the wall and shovel off the red bricks.

Tear down the walls and check for large areas of empty barrels. Before processing and construction to the base layer, the original old wall must be cleaned up, and the bad wall must be thoroughly cleaned, and the wall that has been brushed with latex paint must be polished after disassembly, and the skin and dust on the wall must be removed after polishing.

To fill a small part of the wall with depressions and cracks, you can fill in with plaster, and make sure that the wall is smooth and clean before painting. In order to avoid the problem of peeling and cracking of the wall after painting, the wall base can be repaired and the environmental protection interface agent can be brushed.

Wait for the interface agent to dry before brushing the putty, which can ensure that the new coating is tightly integrated with the original base layer.

I think it still needs to be shoveled, if there is always a new latex paint on the wall, it can not form a good adsorption effect, which is easy to cause the coating to fall off, and it will also make the color of the latex paint appear color difference, affecting the decoration effect.

If you want to paint latex paint on the old house, the original paint on the wall must be removed, if not removed, directly brushed, the latex paint will easily fall off, and the effect will not be very good.

Removing the paint on the wall can be better painted, which can make the paint process effect longer, and can also make the decoration effect look better.

It also needs to be removed, because after the two are mixed, they will have different effects, and eventually lead to peeling.

Yes, so that it can be a good fix and not make the problem worse.

1. The old latex paint needs to be removed. The old wall must be treated with a wall base before brushing latex paint, and all the serious chalking should be removed, and then the putty powder must be re-brushed, and then the latex paint must be brushed.

2. If you re-brush latex paint, the quality of the wall is not good, it will affect the later decoration effect and service life, and will also have an impact on the overall environment of the home. Whether it is wall paint, wall tiles or wallpaper, if you want to renovate better, you should reprocess the base part of the wall.

The old latex paint that was originally brushed needs to be removed, and all the serious chalking on the wall should be removed, and then the putty powder should be re-brushed, and then the latex paint should be brushed.

It is better to brush the primer.

Dulux latex paint is more environmentally friendly and can be used.

This is the balcony, this situation is caused by the cold outside and the heat inside in winter, if you want to **, you still need to shovel to the cement layer, scrape the waterproof putty, and then match the exterior wall paint, so that even if there is condensation, as long as it is removed, the wall paint will not easily send enzymes. Of course, it is best to add insulation measures to prevent condensation. There are also relatively simple methods, such as wiping a layer directly after wiping (as shown in the figure) "three-dimensional self-adhesive 3D wall sticker", the sticking must be comprehensive and reliable, so that there will be no more hair enzyme problems, and it has played a certain role in heat preservation, and the relative workload is also the smallest, you can do it yourself.

This can't be explained directly by whether it can be brushed or not.

Let's analyze the problem in this way.

First, if your wall does not have any blistering, peeling, or hollowing, it can be used as a precondition for not eradicating.

Second, what are the original walls of your house at the same time? If it is also latex paint, it can be removed without eradication, but if it is the original white way, it must be removed.

Third, whether it is a roller brush or spraying, the impact on the original paint is great, it is recommended that you use a wet cloth with water on the wall for about two minutes, if the wall is still strong without any problems, then congratulations you can directly brush again, if blistering, then it is likely that the same problem will occur when you spray, in this case it is recommended that you brush the layer of glue will be better.

If the original wall does not appear chalking, there is no need to eradicate it, note: whether the latex paint is layered, and the surface layer will not fall off the powder when touched by hand.

The retail price of 5 liters of home security is about 120 yuan, and the retail price of 5 liters of ultra-easy washing is about 170 yuan, if you want to go to the next level, you can choose Dulux Gold 5-in-1, and the retail price of 5 liters is about 200 yuan.

There is no need to remove the putty directly from this process, and it doesn't cost much to sweep away the earlier stains. Accept this advice, and you will be satisfied, happy, and comfortable afterwards. Really

Do you still need to ask? Do you want to starve renovation companies and paint factories.

No, you only need to treat the stains that are particularly obvious.

Summary. Kiss! Hello, happy to answer your <>

The house has been painted with latex paint for more than a year, and there is a great smell, and it doesn't work with many methods, and it's okay to shovel it off and brush it again, oh, it's useless. It is necessary to check whether there is a quality problem with the latex paint, and then observe whether there is a window for ventilation, because a long-term space closure is not conducive to the volatilization of the smell of latex paint. If the old wall itself is latex paint, and the overall effect is maintained well, polish it with fine sandpaper and re-brush the latex paint, but if the old wall has peeled or cracked, then you need to remove the wall skin first, and deal with the base layer at the same time, and then scrape the putty twice, and polish the wall with fine sandpaper, and finally repaint the latex paint.

It has to be shoveled, if you don't shovel it, then paint it, it still smells, I hope mine can help you <>

Do you have any other questions?

Thank you! The house was renovated as a whole 7 years ago, the wall is very good, it is a little old, I repainted the wall, has been ventilated or something, the room is empty and I didn't go back to live, I feel that the lack of code is to buy fake latex paint. Is sanding only with fine sand paper equivalent to eradicating the freshly applied latex paint?

The original bureau sail wall is very good, but the color is poor.

Yes, dear.
