The latex paint wall at home is particularly dirty, can you directly repaint it on it?

Of course not, if you brush directly on the wall of the old latex paint, it will wrap the dust and some dirty things on the wall in the new wall, and even the color change of the latex paint surface will appear very dirty because of the dust, and the direct brushing will also lead to the adhesion of the latex paint is not strong, and it will lead to a large area of dry cracking and peeling in the later stage, which is very inappropriate.

If the latex paint is dirty, you should shovel off the original one, and then brush a layer on it, because the wall surface that has been brushed with latex paint will be relatively slippery, and if you brush another layer, it may not be so firm.

Personally, I think it is necessary to scrape off and brush another layer at this time, after all, I think that if you don't hang it up again, it is likely that the corresponding effect will not be achieved.

Not at all. Because after all, if you paint a new layer on it, it will make the wall of the home look deeper, so that you have to paint the whole wall, which is a bit more than worth the loss.

No, at this time, you must remove the original paint and then brush it again, so that it will be more compliant.

Of course, you can, this will save a lot of things, and it can also spend a lot less, which can save time.

Of course not, because this latex paint wall is very special, so it should be treated in other ways.

Latex paint wall cleaning method:

1. It depends on the quality of the latex paint used, the stains and light scratches of the good paint can be removed with a damp cloth and dish soap, or wiped with toothpaste and water and a towel.

2. Slight latex paint wall stains can be sanded with fine sandpaper, scraped off a thin layer, and then coated with white shoe polish.

3. Slight stains on the white wall can be gently wiped off with a clean white rag dipped in water, or you can use an eraser to try to wipe it (the force must be gentle).

Latex paint features:

The main characteristics of latex paint are fast film formation speed, strong shading, fast drying speed, scrubbing resistance, and green environmental protection.

After the construction of the building latex coating is fast, the film is formed rapidly with the evaporation of water, and in the case of good construction environmental conditions, it can be painted and constructed in multiple ways a day, which greatly shortens the construction period and saves construction costs.

Strong opacity and good opacity are the components of high-quality latex paints, which represent better results, less time consumption and less consumption.

First, check whether the wall is hollow, and if there is a local shovel and plastering cement mortar. In the case of no hollowing, sandpaper sanding, due to the contrast between the old and new colors, you will find that the wall is uneven, apply it with diluted 108 glue as an interface agent, and let it dry.

Use construction putty paste or putty powder with water (large white powder mainly prepared with calcium carbonate) to level the potholes and let them dry. 250 sandpaper sanding, sweep the remaining ash, then use putty paste to level, let dry, continue the sandpaper sanding, sweep the remaining ash.

3.Apply latex paint. The primer is added with very little black ink (to a light gray transition color, the purpose is to cover the old paint and putty, to prevent a variety of colors that cannot be covered) once, and then apply the latex topcoat 1 or 2 times after drying.

Materials: 108 glue (or interface agent), putty powder, sandpaper, latex primer, latex topcoat is good. It is sold at local decoration paint shops.

If the old wall has peeled or has cracks, it is not possible to paint latex paint directly. We must first use professional tools to flatten the wall, and ensure that the wall is free of floating soil, the wall is flat, and scrape putty, which can also be a certain amount of white latex on the cheeks. It is usually leveled twice, and when the putty is completely dry, it is smoothed and polished with fine sandpaper.

If the original wall is latex paint, and the foundation strength is good, it can be directly painted after simple hair repair

If the old wall has cracks or peeling, it can't be brushed directly, and then brushed with latex paint after polishing, but some latex paint will have very serious formaldehyde, and the covering is not very good, you can use Yunquan's wall paint instead, his wall paint not only does not have formaldehyde, but also has good coverage, Tmall store has it, you can also look at the coconut net.

It is not feasible to paint the wall directly with latex paint when it is dirty. If there is a stain on the wall, it will directly affect the adhesion of the latex paint. Last time, my family brushed latex paint is the master of 8 Qi Fit, very good!

If the wall is dirty, it is directly brushed with latex paint, which is actually a waste of latex paint in a change of direction. If the latex paint is strongly brushed, there will only be uneven wall surface and the paint cannot be brushed.

You can't brush it directly.

It needs to be sanded before brushing. The reason is that if the direct brush is not polished, the friction is small, and it is not smooth enough, and the latex paint of the brush will fall off or burst the skin, so it is recommended to brush it after sanding.

If the wall is dirty, you can directly paste a layer of wallpaper.

First, check that the old wall has peeled or has cracks. Second, apply plaster to strengthen the hardness of the wall. Third, choose the right latex paint to brush, but even so there will still be some problems, it is recommended that you use Yunquan's wall paint to brush, the coverage is very good, and no pollution, there is on Tmall, 68 yuan can buy a large barrel.

It is best to use latex paint with strong hiding power and strong adhesion, like red apple paint, Nippon, China Resources and other brands are very good.

If the wall at home is dirty and want to renovate, the first thing to see if your previous latex paint appears, peeling, mold, cracking, falling off and other phenomena, if it appears locally, simply repair it, and then brush it directly on it, if it appears in a large area, you need to shovel off all the latex paint on the wall, and then scrape putty, scrape putty steps: scrape the first putty and so on, must be completely dry, start to scrape the second putty, and wait for the second putty to be completely dry, polish with sandpaper, Why wait until it's completely dry? Because if the putty is not dry and brush the latex paint, the moisture inside will be blocked inside, and there will be moisture in it, mildew and other phenomena, so you must wait for the putty to dry completely, and paint the wall, so that there will be no bad phenomenon, it is recommended that you do not brush latex paint, because latex paint is not an environmentally friendly material, and the taste is larger, it is recommended that you brush water-based paint, water-based paint is now one of the more environmentally friendly wall decoration materials, there is no taste, my household Yunquan water-based paint, Water-based paint is more suitable for your own DIY, the operation is relatively simple, you can go to the ** on the look, choose more, look more, there is no harm to yourself.

That's not good, so tell you that you paint a layer of the wall every once in a while, there will definitely be a problem, you might as well use a water-based diatom mud like me to make the wall, my home decoration is water-based diatom mud can be scrubbed, dirty with a wet towel can be very convenient, is in the Tmall store of Yunquan *** buy very easy to use, and there is no taste.

If you can't brush it directly, the wall is dirty, you have to see what material the wall used before, and you have to determine whether the wall base is firm to determine whether it can be brushed. One of the characteristics of this water-based wall paint is that it can be directly scrubbed with a rag if it is dirty, so if the wall of your home is easy to get dirty, you can use this brand to try.

If the wall has peeling, cracking, hollowing, peeling, you need to dispose of the base layer, that is, you need to scrape the putty again, and you need to play sandpaper, sometimes you need to play plaster to strengthen the hardness of the wall, even if these are all strictly finished, just brush the latex paint is not good, when the wall of my house was renovated a few years ago, I was looking for the best Yunquan Home *** to deal with it, they all helped me pack and deal with it, I am quite worry-free, mainly Yong are diatom mud and other environmentally friendly coatings, You can swipe and live.

If the wall is dirty, you can't brush the latex paint once, and you need to shovel off the paint surface of the previous wall and re-apply the putty to apply the latex paint. However, latex paint has a high formaldehyde content, which is harmful to the body, and it will take a while to move in. At that time, the wall of my house was dirty, and the wall effect of the construction was good.

Latex paintThe wall cannot avoid the possibility of getting dirty, especially in families with children, because of the naughty nature of children and likes to doodle, it is a disaster for latex paint walls! So if the latex paint wall at home becomes dirty, should you directly brush another layer of latex paint, or is there any other good way?

<> friend said that there was no way for the child to be too naughty to use the wall as a blackboard, and at the same time regretted that in order to save money, he decisively chose the affordable latex paint decoration, and underestimated the child's mischievous ability, and the wall was painted before a year of moving in! I smiled and said to my friend, "It's quite artistic!"

Sometimes I think it's familiar, and I don't look at the switch when I press it, maybe I twist my head to the side to look at something else; Sometimes it will press against the wall. As for the aisleSunny angleWhen children or adults walk by, they will habitually touch it with their hands, and they will leave some traces. But latex paint has a drawback, that is, it is easy to change color and yellowing after a long time, that is, the original reserved latex, and then paint on the brush is not a color, if you want to be clean, you have to brush the whole wall again, this is more troublesome, but also to move the furniture, if you move in, it is not environmentally friendly.

Paint latex paint directly on the original wall. In the case of the original latex paint wall is flat, it can be directly constructed in the form of roller rolling, and there is no need to hire workers at all, you can do it yourself, and remember to do a good job of ground protection before construction. If the wall is damaged or uneven, putty can be used first.

Or plaster is repaired and then coated with latex paint. In the case of the original latex paint wall is flat, it can be directly constructed in the form of roller rolling, and you can do it yourself without hiring workers, remember to do a good job of ground protection. If the wall is damaged or uneven, it can be repaired with putty or plaster before applying latex paint.

It may be that the dirty ones will not be so noticeable or use too wetwith tooDirty rags scrubbing the walls will also cause the dirty area to become larger and larger; There is also a lack of timely use of a feather duster to clean the dust on the surface of the wall, once someone rubs the dust, the dust will adhere to the surface of the latex paint

I don't think this is okay, because directly brushing the latex paint on it is not firmly pasted, it is easy to fall off, and it has to be repaired again in the end, which is very troublesome.

Of course, you can, but you should first polish the original paint surface when painting, otherwise the new paint will easily fall off.

If the latex paint wall at home is dirty, can you directly paint another layer of latex paint? Latex paint wall renovation can not be directly painted with latex paint. If you paint latex paint directly on the old wall, the wall is prone to cracks, empty barrels, and falling off in the later stage.

Not only did it not achieve the desired effect, but it even needed to be re-constructed, so it was necessary to treat the foundation before applying latex paint. Before wall decoration, be sure to shovel the wall, including before the putty layer, before the wallpaper and before the wall decoration, which can prevent the refreshed paint from falling off, and can also reduce the probability of cracks, hollowing and falling off the wall in the later stage, so as not to bring unnecessary trouble to the follow-up work. Old wall renovation must use primer, primer and sealing substrate can resist moisture, not only to better protect the paint, but also to improve the texture and hiding power of the paint.

<> if you don't do a wall primer, the renovated wall is easy to blister and mold, and it is easy to discolor after a long time. If a freshly painted wall is exposed to sunlight for a long time, the color of the wall can easily peel off and turn yellow. And because of the different temperature difference between the inside and outside of the wall, when the temperature of the wall surface drops, the latex paint on the wall is prone to cracks, so it is best to cover the wall with concealment and let the wall dry naturally.

If you don't know the base layer of the wall, it is recommended to refresh the latex paint repeatedly. If there are cracks, peeling, or a little ash on the wall base, it means that the quality of the wall base is not good, if the wall base is not removed, sanded or repaired in this case, and the latex paint is directly brushed, then it is likely to cause the wall to crack just after painting.

Check the condition of the wall foundation, all hollowing, falling off and other local areas must be repaired first, the specific repair method is to remove the lesion wall skin, scrape putty and plaster again, and wait for the material to dry. The repaired place is roughly sanded, and then the overall fine polishing of the wall is carried out, which can not only make the uneven place tidy, but also polish off the original wall dirt and improve the absorption of latex paint on the wall. Finally, the old latex paint wall that has been processed is painted, and what I want to know is that the more latex paint is painted, the better, generally 2-3 times is enough.

If the wall paint is too thick, irregular cracks will also form, affecting the appearance.

If the latex wall at home becomes dirty, it is not possible to directly brush another layer of latex, you need to cut off all the old latex before you can repaint.

I think it is possible, you only need to sandpaper the dirty area, and then you can apply a layer of latex paint, which can make the whole home look new, and it also saves time and effort.

OK. Another layer of latex paint can cover the original dirty area.
