No. The reason why you can't brush directly is because after a long time after direct brushing, the original paint will age and fall off, and it also has an impact on the viscosity of the paste, so it is best to sandpaper first and then paint.

Therefore, when renovating the old wall, we must first look at the overall wall surface and how damaged it is. If the damage is very serious and there is already peeling, then you should not apply the paint directly.

Requirements for refurbished paint for old walls:If the old wall has peeling or cracks, you can't paint it directly, you need to take professional props to smooth its outer layer to ensure that there is no floating dust to be able to paint, and you need to add an appropriate amount of white latex to the putty, and then do two leveling, and wait for the putty to dry and polish with sandpaper.

When many owners are faced with the renovation of the wall of the old house, they must have such questions: can the old wall be directly painted with latex paint without polishing, and what will be the consequences if it is not polished.

If the old wall is originally brushed with latex paint, and the base condition is relatively good, without any damage, the wall can be directly applied to the latex paint, but be careful not to destroy the integrity of the original wall paint film, and do not use latex paint that is much better than the original wall latex paint, otherwise it is easy to peel and fall off; If the original wall at home is not very good, it is recommended to redo the wall, and then apply latex paint after scraping putty and sanding, and it is not recommended to save the decoration cost of the wall, otherwise it is easy to have various problems in the later stage.

The unevenness does not exceed 3 mm, and finally the primer and top coat are brushed.

In short, whether the old wall can be directly painted is also divided into situations, the situation of each family wall is different, the scheme used is also different, it is best to combine the situation of their own wall to judge whether it is directly polished and painted, or the overall eradication of the new paint, at the same time, it should be noted that when the old wall is painted with refreshed latex paint, it is necessary to deal with cracks and warped skin, for hair-like cracks, direct elastic products can cover fine cracks, and for larger cracks, it is recommended to fill with primer mixed powder, After smoothing and sanding evenly, the construction is low, and the topcoat is low.

If the original wall is originally latex paint, and the foundation strength is good, we only need to paint latex paint after a simple repair, and if the original wall has appeared patent leather or fall off, we need to shovel off the original wall.

Steps to brush old walls with latex paint.

Step 1: Keep the wall flat.

If the old wall has peeled or there are cracks, we must first use professional tools to flatten the wall and ensure that the wall is free of floating soil, floating and sinking, etc., so that the bond between the newly painted latex paint and the wall can also be stronger.

Step 2: Scrape putty and sand.

In order to make the wall more solid and flat, we need to scrape the putty, usually twice (the time interval between the two passes must be grasped), and when the putty is completely dry, then smooth and polish it with fine sandpaper.

Step 3: Apply primer and make up for it.

After the putty wall is polished, the next step is to apply the primer, if the wall eats a large amount of paint, you can add some water to the primer, which can also make the paint more even, it is worth noting that do not use a poor roller to apply, to choose a roller with the same texture as the topcoat, after the topcoat is dry, we need to level some small defects.

Step 4: Paint and maintain.

When painting on the paint, we must grasp the amount of water mixed with the paint, because it affects the thickness of the paint film, the hardness of the paint film, etc., the hair of the drum can not be too short and too fine, the paint film is more perfect, and so the paint is dry, do some care work, it is best not to scrub or any contact with the wall within 8 days.

Precautions for wall renovation:

If the original melamine paint is made, remove the paint film and re-scrape the putty. Applying emulsion paint directly on it is prone to peeling off.

When applying putty on the old paint film, it is necessary to pay attention to the uniform grinding, otherwise there will be a phenomenon that the paint film will bloom after construction due to the different absorption of the substrate.

Recoat the old latex paint film again, you need to deal with cracks and warping, for hair-like cracks, you can directly cover the fine cracks with elastic products, for larger cracks, it is recommended to fill them with primer mixed powder, smooth and polish evenly after the construction is low, topcoat.

Brush directly, it doesn't seem to work, my house is six or seven years old wall, some time ago when it was renovated, the old wall was snatched away, scraped the new putty powder, and then brushed the water paint of Yunquan!

The peeling of the old wall can not be directly brushed with paint, and the direct brushing is not only unsightly, but also easy to peel and crack again in the later stage, so it is recommended to do it first.

The version of the putty polishing is flat in the coating, and it is not recommended to do latex paint, one is formaldehyde, the other is that latex paint is easy to peel after a long time, mold, cracking, you can try environmentally friendly paints, such as diatom mud, environmentally friendly wall paint, my home is Tmall Yunquan water-based wall paint, it is better, no peeling, no formaldehyde.

Of course, it is best to start brushing after cleaning and sanding, so as to prevent blistering on the new brush, which is more troublesome.

No. The original wall paint and putty need to be shoveled off. Then follow the normal steps of applying latex paint step by step. They are all brushed with putty powder first, and latex paint after leveling.

To paint latex paint, you must first remove the old wall skin, and it is best to brush putty before applying latex paint.

Can the renovation of the old wall be directly painted with latex glue paint? This first depends on whether there is dao peeling and cracking back on the original wall.

Moldy, drums and other phenomena, if there is no direct brush, if you directly brush it is a waste of time, the correct way to deal with it should be to deal with the wall first, shovel out all the bad places, scrape the putty again, and ensure that the wall is flat, so that you can brush directly after re-processing, but if you want to re-brush, I personally recommend that you do not use latex paint, because the latex paint smells too big, really to be honest, it will really have a headache after smelling for a long time, Now there is a relatively new type of environmentally friendly material, called Yunquan water-based paint, you can go to see, there is no smell, you can find it directly on the **.

Yes, yes, but be sure to buy it.

Good latex paint. Now latex paint is true and false, a special must polish the eyes, buy the real genus on the line, how long to stay this is not a general range, latex paint smell very big, if not water-based then it is recommended to put a period of time and then move in. And if you are painting the wall, I would like to give you a personal suggestion that I feel better about the diatom mud now, because there is really no smell after brushing, and it is 0 formaldehyde, no benzene is added, and you can move in immediately after drying.

Although the real Nippon paint is also a qualified product, but qualified does not mean that it does not contain benzene, so now health is really important, I used to decorate my home before the Yunquan water-based diatom mud purchased in Tmall, which is very good, and my personal suggestions are for reference only.

Is it okay to renovate the old wall and paint it directly?？The renovation of the old wall can not be directly brushed with topcoat, the old wall should be polished, the oil stains and dirty spots on the wall should be removed, the gaps and holes should be filled with putty, and the sandpaper should be sanded and smoothed to remove the dust on the wall and the topcoat should be painted.

1. For the basic treatment of the bright surface of the old wall, clean up the decorations that do not need it, fill the nail holes, polish it with coarse sandpaper when the wall is relatively flat, remove all the dirty places on the wall and let the old, clean the dust on the wall with a brush, and re-brush the new latex paint.

2. When the old wall is dirty or oily, the cover is slippery and wide, and it is not possible to let the latex paint fit, and the latex paint must be sanded before it can be brushed, especially the wall that has been brushed with paint and latex paint, it must be cleaned up to paint, and the adhesion of latex paint is relatively poor compared to the paint, so it cannot be combined with the paint and the original latex paint wall.

3. When the hole or wall peels off, the original wall should be repaired, and the large area should be repaired as much as possible, and the small area repair will cause serious color difference. When renovating old walls, the existing pollutants and peeling wall skin should be removed in a large area, and latex paint should be applied after the repair is complete.
