How to remove putty powder from old walls.

If you want to repaint the wall, is it feasible to not shovel the putty of the old wall?

Before the putty removal work, you can use a watering can to spray an appropriate amount of water on the wall, and then wait for about half an hour to soak the putty on the wall, and then remove the putty, it is very easy. If you still can't get rid of it, spray it with some water and wait for a while to remove it. First of all, whether the wall shovel shovels putty or not have to be judged according to the situation of the wall.

If the wall is peeling, chalking, severely cracked, moldy, etc., then the putty must be shoveled. But if the walls are just simply dirty, black, latex paint.

If there are tiny cracks on the surface, or if you have wallpaper, you only need to spray latex paint again after sanding.

The first is that the second-hand house has peeled and fallen off, and a lot of it has to be shoveled. If you don't remove the putty from the old walls, you can't paint the walls. If you force paint it, the new putty may not stay on the wall for long.

If you don't remove the putty wall, spray latex paint or wallpaper directly on it, it will definitely cause cracking in the later stage. After all, the service life is long, and the putty wall made before will be imperfect in many places, so it is better to prevent problems before they occur.

The second type of old wall renovation without shoveling putty is also possible, but the following conditions must be met:1The old walls are not blistered, peeled, or hollow.

2.Old walls can't be white. Generally, latex paint walls can be renovated directly without shoveling. 3.Test old wall coatings. Apply a damp towel to the old wall for about two minutes. If the wall remains the same, it can also be repainted.

Whether to shovel or not depends on the specific situation of the old wall. Because various problems will naturally appear on the old walls of the house, such as unpacking, peeling, etc. At this time, everyone will want to restore it to its previous beauty, such as coating it with diatom mud.

to renovate. The walls facing these problems must be dealt with seriously. If these problems are not dealt with, the protrusions in front of the wall will continue to burst.

If you do diatom mud directly on it, it will directly affect the service life of diatom mud. In general, the service life of diatom mud is about 20 years.

If we want to shovel the putty powder from the old wall, we can buy a small stainless steel shovel. If you don't eradicate the old wall putty, you can't, even if you brush it with new powder, the effect is not good, and it is easy to fall off.

The pre-treatment method for scraping putty for the renovation of the old wall is as follows:

1. First of all, the base layer of the wall should be cleaned first, and then the impurities and dust on the wall should be cleaned up with professional construction cleaning tools, and the wall must be kept clean and tidy.

Then the wall interface agent is painted, special attention should be paid to the thickness of the interface agent and the uniform painting during construction, wait for three hours of natural drying after painting, and the wall surface is painted with the interface agent to make the wall completely closed, so as to avoid the formation of putty due to the non-stick situation of the wall.

2. When the wall is painted with interface agent, if the construction is summer, the wall must be painted with water first, which is to increase the wetness of the wall base. In order to avoid excessive water absorption when applying putty, cracking will be formed. If it is a new construction cement wall, it must be cured for a period of time before putty can be applied.

3. If it belongs to the wall decoration of the old house, some walls will have problems such as mold and moisture regeneration because of long-term use. First of all, it is necessary to remove all the wall skin, if the wall has cracks, it must be directly paved with mesh cloth, which is an anti-cracking material, to prevent the wall from cracking.

Precautions when scraping putty construction

1. Before scraping putty, you should use a ruler to measure. If the wall is flat, then you can scrape putty. When scraping putty, it is necessary to scrape twice, so that the wall can be relatively flat, and the background color of the wall can be completely covered.

However, when applying putty, there should be an interval of two hours between each putty. And the wall should be in a dry state before it can be painted with putty.

2. When scraping the first layer of putty, the peeling and cracking of the wall should be cleaned up, and then filled with cement mortar. Then you have to shovel the remaining residue and clean the wall.

RenovationThe so-called complete renovation of the wall of the second-hand house means that we remove all the decorative layers of the original wall. This involves removing the latex paint from the wall, removing the putty layer from the wall, and exposing the plastering layer inside. Second-hand houses because the original rubber has been inhabited, so there are more or less paint or stains on some parts of the wall.

If most of the whole thing is dirty, it is recommended to renovate it all!

It's not easy to shovel, so don't embarrass the workers, even if they are capable, the labor cost is not the same. At this time, the best thing to do is to shovel some dirty areas on the wall and smooth them with putty. Apply latex paint directly or paste wallpaper.

The quality of the putty on the original wall will generally be poor, and it is easy to crack, peel, and pulverize in the later stage of direct brushing latex paint, so it is recommended to use gypsum leveling after all the eradication, and then scrape the putty and then roll the latex paint, which is more reliable. If the damaged pit is too deep, it is recommended to repair it with gypsum powder and then repair it with putty powder; Now many owners generally have two ways to deal with this wall, one is directly pasted with wallpaper, one is directly painted, with good coverage of latex paint is still possible, excessive, if the decoration to the age, the conditions are still allowed, then redesign and decorate.

In fact, the wall is to polish the layer of latex paint on the surface of the paint, so as to prevent the new and old materials from falling off without fusion. For how to remove putty powder from old walls, there are actually many methods, including the use of wall planers, angle grinders, etc., but the dust with the machine is indeed too big, and ordinary people can't stand it. And the simplest is to wet and blister with water, and it is easy to shovel.

To get the worst things, we still have to shovel off, and after shoveling off, we also need to roll the wall solid, not to mention the waste of construction progress, not to mention the cost of an extra cost. If you feel that the wall is dirty, you can brush all the wall solid, and brush the latex paint with putty twice after scraping, as long as the wall is fine, the putty will not fall.

You can't paint directly on the old putty powder, because the old putty powder has been around for a long time, and its surface is also very unsmooth.

It is not allowed to paint directly on the old putty, as this will make the wall look very thick and not have a very flat effect.

Of course not, if you do this, it will only make the wall crack or peeling phenomenon in the later stage, so we must remove all the old putty powder before painting.

The secondary renovation of the house, indicating the previous interior decoration, occurred aSome common product quality problems, endangering the daily living environment, quality of life and emotions, many people in this case, choose the overall secondary decoration in the room, the floor tiles are easy to shovel off, including the removal of some ceiling materials, soon to be able to dismantle neatly, only the interior wall putty powder on the wall, it is very difficult to shovel off, it is a particularly time-consuming and money-burning engineering project. Interior wall putty powder scraped on the walls very thinly

It's not thick, and it's not easy to describe it on A4 paper, but if you want to shovel off such a thin interior wall putty powder, the difficulty factor is obvious. In fact, there are many ways to shovel off the putty powder of the interior wall, there are pneumatic tools for professional grinding putty powder, you can also carry out grinding and polishing as long as you turn on the power supply, the rate is very fast, although there are many advantages, there are also shortcomings and problems, grinding and polishing vibrating cement wall is very easy to crack. The walls of the old house are cement batches, normally the white cement wall does not leak, before the house was built, the wall was mixed with lime powder and gravel to paint the wall, <>

It is very likely that the compressive strength is not large, and it can be shoveled off immediately with a shovel or the internal structural bricks are separated from the painting layer, which is simply said to be a hollow wall, and the wall can be directly repainted, and then the normal procedure process engineering construction can be! After the wall putty is sprinkled, it is still not good to shovel, indicating that your method is not right, the wall putty can not be simply sprinkled after blanching, and then immediately and gradually shoveled, must be evenly and several times sprayed, and the wall should be soaked all over, and it is more convenient to shovel it down at this moment.

Wall putty with a planer is faster, and simple, tidy, a house for one person, more than a day to solve. This pair of wall putty is passed over and over again, the thickness of the wall putty is thick, and the shade of the blade of the planer can also be adjusted. Today's top-of-the-line planersThere are also anti-fouling, as long as there is electricity, the edges can be shoveled, which is much simpler and more convenient than manual shoveling.

But the planer has drawbacks, this thing can not be shoveled, the planer weighs a pound, the shovel top should be lifted hard, this time will be particularly inconvenient, walking is even more inconvenient. Therefore, the top will eventually have to be cleared by manpower.

If you want to shovel off the putty powder, you must first soak the wall and soak it thoroughly, so that the putty powder can be softened, and you can also avoid the dust in the process of shoveling the wall, and then use some sharp iron tools to knock the putty layer down, roll clean water on the drum, and repeatedly operate to let the water fully penetrate under the putty layer, so that it will be particularly easy when shoveling the wall.

It can be handled with some small shovels, and some watering cans can can be used for better cleaning.

In the second renovation, you should first scrape these putty powders, then clean them with water, and then scrape the putty again after smoothing them.

You can use a professional scraper to scrape off these putty powders. In this way, it can make the second decoration of the house more convenient and fast.

If the putty material is particularly bad, we can soak it with water and remove it as much as possible. In this way, only the putty protruding from the wall can be shoveled off, and there is no way to shovel the hollow part of the blade. Next, you need to use a shovel to mark the putty in the sunken position to get better adhesion conditions.

At this time, you must seek the help of a professional decoration team, and you must be a professional construction worker to clean up the putty, and scrape off all the putty and repaint it.

In fact, these putty powders also have to use some shovels, all of which are shoveled down, so that it is convenient to decorate them for the second time, and they can also have a good effect.

Personally, I think that if you want to clean up the putty powder on the wall, it is necessary to use special tools at this time, and general decoration companies have relevant tools.

Of course, it is necessary to shovel off, the old putty layer and the new putty layer will repel each other. No matter how well you scrape the surface, if there is a problem inside, it will always affect the surface. Shovel until the cement layer is seen, and then use white cement and 801 glue to stir together for priming, and then scrape putty on the surface, so that there will be no anti-moisture, peeling and mildew in the future.
