The steps of scraping the wall, the basic steps of scraping the wall

1. No interface agent is required.

2. You can scrape the white cement or putty made of gypsum powder first.

3. Now it is generally not necessary to use a good cloth, the gap can be pasted with a bandage, and the glue used to paste the bandage is high-quality white latex.

5. It is precisely because of this last point that I will not say anything more here - because, if you just scrape putty, you can directly use white cement and glue to make putty to scrape the wall, then you can temporarily do not brush latex paint, but the effect is not as good as latex paint, if it is formally decorated, it is still necessary to use putty to level and brush latex paint.

Putty generally does not have waterproof function, but exterior wall putty has the ability to resist water, but ordinary putty is generally used for interior decoration, and very few water-resistant putty are used.

Hello, the wall of the new house generally does not need to be shoveled, but the premise is that the hand does not fall off the white (wall ash) when touching the wall, and then use the Meichao brand "wall shovel" (interface agent) roller to coat it, and the old house needs to be shoveled off, because the wall surface will be pulverized because the years are too long, (the roller interface agent is not good), so that it can not be bonded with the newly scraped putty. Note that the wall surface that has been shoveled off the old wall skin should also be rolled with an interface agent before scraping the putty.

1. Treatment of wall base layer. The base layer of the wall that does not destroy the same faction has different construction requirements when the base is treated. For cast-in-place concrete walls, because the wall often has some porosity and bulging phenomenon, it is necessary to repair the wall surface, the protrusion should be smoothed, and the depression should be filled.

For precast concrete floor slabs, there are often some gravel and bumps on the surface, so professional construction personnel need to brush the wall as a whole with a wire brush to remove these debris. For the cement mortar paper reinforcement ash surface layer, the surface of the wall is required to be dry, solid, clean and oil-free.

2. Repair the base layer of wall pants. After the treatment of the base layer of the wall, there will still be some large wall depressions, so it is necessary to use gypsum putty to preliminarily fill these depressions.

3. Brush caustic soda aqueous solution. The main purpose of brushing caustic aqueous solution is to clean the oil stain on the concrete wall.

4. Scrape the big white putty. The batch scraping of putty generally needs to be carried out two to three times, and the putty of the last pass must wait until the putty of the previous one is completely dry before carrying out the construction operation. After the putty is scraped, the whole wall is required to be smooth and smooth, with uniform texture and no scratches on the surface, otherwise the overall decoration effect will be seriously affected when the latex paint is painted in the later stage.

Wall scraping is a basic process before painting, the purpose is to remove dust, dirt and old paint layers from the wall, so that the new paint can better adhere to the wall. Here are a few ways to scrape walls.

1.Batch ash machine batch scraping method.

A plaster is a power tool that shapes materials such as paint, clay, and plaster evenly into a variety of surfaces. When using the plaster machine, the depression on the wall surface is first coated with plaster, and then the plaster on the wall is mixed and polished with the plaster machine, so that the wall surface is smooth and flat, and the wall scraping work can be completed quickly.

2.Hand scraping method.

Manual scraping is a traditional method of scraping walls, which requires the use of tools such as shovels and scrapers. Spread the paint evenly on the wall, then wipe and level the wall with a shovel or scraper so that they fill and spread on the wall. Manual scraping can be done on small areas and is particularly suitable for delicate restorations.

3.Grinder batch scraping method.

The sander is an electric cherry blossom first action tool with a grinding stone disc or sandpaper that can quickly polish and trim small bumps, depressions and breaks on the wall. When using a Dazhou Songque mill to scrape the wall, you need to choose a suitable sandpaper or grinding stone disc, and carry out different levels of grinding according to the degree of wear and tear in different positions on the wall.

4.Wash the remaining scraping dust.

Cleaning the remaining scraping dust is the last step in the scraping process. Use clean water and clean towels, sponges and other tools to wipe the wall tightly clean to ensure that the wall surface is clean and flat. This is essential for the adhesion and aesthetics of new coatings.

When scraping the wall, it is necessary to pay attention to the use of correct tools and methods, different surfaces need to use different scraping methods to ensure that the wall surface is clean and smooth, and finally reach the early arrival of the new paint on the wall evenly adhered and beautiful and lasting effect.

Summary. Hello dear, glad to answer for you. How to scrape off the wall skin, use salt water to pour the wall skin quickly, because salt water can reduce the hardness of the wall skin; Use a shovel against the direction of the wall skin, shovel off part of the wall skin, and use an iron brush dipped in a little dish soap to brush the remaining wall skin.

Choose to use a wall shovel, which is very time-saving and easy to operate. Manual labor can still be omitted, because people's work efficiency is not high, many times we lie on the wall and scrape for half a day to scrape down a few walls. Don't be afraid to spend money during construction, the technology of each wall shovel is relatively mature, and it is easier to use.

Each has its own unique advantages in a certain characteristic, so if you want to buy for a certain aspect, it may be more efficient.

Hello, I'm glad to answer for you, it will take some time to sort out the answers, please be patient.

The precautions for scraping the wall are as follows: 1. Pay attention to the flatness of scraping putty not only requires the flatness of the construction position, but also requires the flatness of the putty itself after construction, generally speaking, the flatness of the putty also has a certain relationship with the quality of the putty.
