When decorating, how to eradicate the ordinary putty flowing down from the original wall?

1. Use a roller or brush to dip in water, roll back and forth on the wall two to three times, and take the wall to eat enough water as the standard;

2. After five to ten minutes after the wall is fully watered, the adhesion of the original paint to the base layer will be reduced, and even peeling, at this time, the paint can be easily removed with tools such as shovel and batch knife;

3. When removing the paint, if you find that the base layer is still very adhesive, you don't need to shovel it again, just remove the pulverized or poor adhesion, and if you find that the base layer is soft and weak, you can remove it all;

4. Use cement mortar for wall leveling to achieve the basic required flatness.

5.Wall planer, also known as wall shovel machine, old wall renovation machine, rough planer, is mainly used for wall uneven repair, old wall renovation treatment. Operated by one person, it can save three to four times the man-hours of traditional use of small blades.

I think it's good if you use a knife to scrape off little by little, and you can use sandpaper to sand slowly, so that the damage to the wall is also small.

The normal way is to shovel it off, but it can feel time-consuming, and some people will use a special hammer to gently knock it off, and then it will fall off naturally.

The specific ways to quickly remove putty or paint from the wall of an old house are:

1. Spray water twice with a sprayer or roll both sides with a paint stick, and the wall can be easily removed with a shovel after it is wet. However, you can also try it partially, if you can't shovel it, it means that the original wall is good, and you can polish it with sandpaper.

2. Wipe off the dirty parts with dish soap first, and then wipe the dirty parts with clean water, including the surrounding part, so as to ensure that the wiped parts will not have obvious color difference with the original paint surface. If there are still traces, you can go to the stationery store and buy a "high-end painting eraser" (the translucent kind) and wipe it clean with a few wipes.

3. Take a fine sandpaper to polish the dirty place, and light the place where you wipe, and focus on polishing the dirty one. If it is a colored latex paint, you should pay more attention to the strength when sanding to prevent excessive sanding and exposing the bottom.

4. The shovel blade is the kind that can replace the art blade, so that the wall absorbs water and wets the wall, and before the wall is produced, the wall is rolled several times with a roller dipped in water, and it is easier to shovel it after a while.

In general, the wall skin will be shoveled off (batch putty layer) for the decoration of old houses, and the surface of the wall will be damaged due to the aging of the wall skin surface or the demolition and vibration in the early stage of decoration. After shoveling, the surface dust should be washed off with water, and the wall should be brushed after drying.

I'm done, like my click to follow. If it is not eradicated, the thickness of the new wall will be thickened, and the new wall will have strong adhesion, and after drying, it is easy to pull up the old wall skin, resulting in cracking and hollowing of the wall.

Shedding and other problems. Ten years ago, many people did not remove the original white ash layer from the wall. At that time, the practice was to remove the heavy batch of putty from the partially damaged, hollow and peeling parts, and the rest of the wall was rolled with glue, putty, sanding, and rolling latex paint.

Again, quality problems are rarely found. Whether the original white ash should be eradicated in the process of old house decoration, I personally think it mainly depends on two points, 1. The original decoration period of the old house, and whether the owner of the old house originally invested or lived by himself. 2. See, touch, see if there is any phenomenon such as depowdering and hollowing.

Let's take a look at the details!

<> many second-hand houses purchased by owners have to be redecorated, which also gives them a headache; Because the walls of some second-hand houses have peeled; The following Chenyang water paint will give you a detailed analysis of the old house decoration process, whether the old wall skin needs to be removed? Shoveling the wall skin is not a must, and it is necessary to shovel the wall skin when the wall of the old house is scraped, loose, hollow, and the latex paint brushed and the wall is not firmly combined. and even large areas of shedding.

Moreover, the decoration of the old house will definitely involve some changes to the ceiling, water and electricity, and partition walls, and the reserved walls should be planned before the eradication, and the pipeline direction of water and electricity, whether there is a ceiling, etc., so as to avoid the waste of labor after the wall skin is removed in front of the wall and due to the later changes. The demolition of the old house wall If it is not demolished, it will affect all kinds of scraping putty in the later stage.

Hanging the heater will also affect the hole in the wall, so it is best to dismantle it, so that although the amount of work is large, it will definitely not affect the later use.

It must be shoveled, 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 stir with white cement and 801 glue to play the role of priming, and then scrape putty on the surface.

In this way, there will be no anti-damp, peeling and moldy in the future.

To dismantle, when refreshing the paint, you have to shovel off the old putty, which is also to facilitate the refresh of the paint, and the retention of the putty will also have a bad effect, which will make the paint not beautiful enough.

Definitely going to shovel it off. If you don't shovel off the original putty yourself, then after repainting, the walls will be ugly.

To shovel off. Because the original putty will affect the painting, it may cause unevenness, so it should be shoveled.

When decorating a house, you will encounter various building materials. After using these building materials, we will smell the smell they bring. Take putty powder, for example, it has a great effect on painting walls. During construction, scrape the water-resistant putty in batches and try not to leave scratches. <>

Due to its high strength, post-polishing is basically difficult to achieve if scratches are left. Sanding should be carried out in a semi-dry state as much as possible, so that it will be easy to sand, smooth and smooth. The adhesive mortar of exterior wall putty powder is straightened with a trowel.

Scrape a thin layer on top of foundation. At the same time, quickly apply an appropriate amount of adhesive mortar on the bottom surface of the construction. Putty powder needs to use a tooth edge with a suitable pitch of 60-70 degrees along a straight line.

Also, this method is good when removing putty. The rollers are connected and lengthened with wooden sticks. After soaking in a bucket of clean water, pick up the roller brush on the wall to be cleaned and roll it less than twice.

Once the water is completely absorbed, shovel with a shovel. It's easy to fall off one by one. After shoveling, the wall can be completely dried, and then stick to scrape putty, scraping putty is one of the methods of indoor wall decoration, that is to say, to remove the uneven part of the surface of the base layer, keep the wall flat and smooth, is an important step in the foundation treatment.

The specific method is to scrape putty on the wall to ensure that the wall surface is flat. Generally, it is scraped three times, dried and smoothed with sandpaper. Putty is formulated with a small amount of binder, a large amount of filler and an appropriate amount of coloring pigments, and the coloring pigments mainly include iron red, carbon black, chrome yellow, etc.

After the plaster putty is dried, scrape the putty. There are two ways to detect whether the putty is dry: one is to observe whether the color is consistent; Then see if there is any "sticky sandpaper" when sanding.

Oblique polishing with strong light, top surface can be used 360 sandpaper. This deserves our attention. Also, be aware of this.

According to the performance and basic conditions of the coating, choose the appropriate putty and scraping tools. When filling the holes and cracks of the base layer with a putty knife, press the blade with your index finger to press the putty into the defect, fill and fill it, scrape off the surrounding putty, and minimize the traces of putty. Since putty powder is so important, it is important to master the relevant methods of buying and removing putty powder.
