First, after the old wall skin is removed, what you see is the base layer of the wall, after cleaning up the floating ash or stains on the surface of the wall, first of all, we must test whether the alkalinity of the original wall is strong, if the alkalinity of the original wall is very strong, directly scrape the putty, it will react with the original wall, which will lead to the occurrence of putty flowering, powder, falling off, etc., if the original wall is strong alkaline, you need to use anti-alkali primer to treat the base layer of the wall, like the Xiujie anti-alkali primer used in my home decoration to do the bottom sealing treatment of the old wall, after the bottom sealing treatment, It can make the alkaline substance of the base layer not leak out, which can greatly extend the life of the wall decoration.

Second, look at the wall base is not strong, if the wall is not strong, do not scrape the putty directly, otherwise it is easy to fall off, the wall is not firm, you can use the interface agent or wall solid products to brush 1-2 times, can improve the density of the wall base and improve the adhesion ability of the wall.

Third, the flatness of the wall, if the whole wall is seriously uneven, or there are gaps and the like, in the place where the height difference is large, it is necessary to use the plaster bottom layer for leveling, and the gaps can be treated with special caulking gypsum to ensure the basic smoothness of the wall.

If your wall base does not have the above three conditions, you can directly scrape putty, if there is, you can do it step by step.

Putty is the putty on the old wall, of course, to shovel off, do not shovel off the old putty wall and the new putty can not be combined, will produce the phenomenon of wall skin falling off or bulging, must be shoveled to the bottom of the cement and then use glue and putty to stir, as a base use, wait until the bottom layer is completely dry, and then scrape the putty operation, so that the wall skin will not be peeled when it encounters water.

1. When scraping putty, the wall must be in a dry state, fill the cracks and holes at the bottom layer, and then scrape the putty after filling, so as to prevent the holes from drying and cracking the putty layer, when the first layer is scraped, it should be dried after thorough drying, sandpaper is used for sandpaper, the second layer of stucco is painted, and the putty is generally operated three times to make the wall smooth and smooth.

2. Putty is elastic, the second layer should not be applied before it dries, in case the wall cracks, when the first layer is dry, the second layer is smeared, even if the first layer is dry, there will be a second layer to make up, in the continuous polishing, the subtle cracks will be polished clean, so that the wall is in a smooth state.

3. The ratio of putty to water is that it must be stirred more than three times before it can be used on the wall, and the putty can not be used overnight.

For the decoration of new houses, whether to remove the putty on the wall.

Kiss Glad to answer for you: New house decoration, whether the putty on the wall should be eradicatedAnswer: Kiss If the putty on the original wall is waterproof putty, it does not need to be removed.

Other putty should be removed There are several ways to identify the quality of wall putty: (1) You can observe whether the wall putty has an abnormal situation. You can wipe the walls with your hands.

If the hands are covered with white ash, then the quality of the wall putty is poor. If there is no ash, then the quality of wall putty is good. You only need to brush the glue twice, then apply the putty to the wall 2-3 times, and then polish it after drying.

Finally, apply latex paint 2-3 times and you're good to go. (2) If there is no powder falling on the wall, a waterproof test is required. You can spray a small amount of water on the wall, then wipe the wall with your hands, and then check the wall for a substance similar to batter.

If there is, then you need to shovel off the wall putty, if not, you don't need to shovel it. Of course, if everyone's budget is objective, you can also choose to shovel off the wall putty. (3) If you see a large area of protrusion on the wall, it means that the putty on the gray wall is of poor quality and must be shoveled.

4) Owners can also use a shovel to find a small corner to try it themselves. If the shovel can't be shoveled, the quality of the putty will be fine. Then the owner can decide whether to shovel the wall putty according to his actual situation and economic ability.

Whether the putty on the wall of the rough house needs to be removed should be determined according to the acceptance results.

Before decoration, the quality of the wall needs to be checked, and it is recommended to remove it if the following conditions exist:

1. The putty on the wall has poor water resistance.

The putty on the wall has poor water resistance, and it is easy to crack the wall, peel and fall ash, mold and other problems in the later stage, the identification method can be to splash water on the wall, and then rub the wall with your hands, if the fingers are stuck with white slurry or the wall is paste, it means that the putty has poor water resistance, and it is recommended to eradicate it.

2. The curing strength of the gypsum plastering layer under the putty is poor.

Scrape off the putty layer on the surface, and then rub the wall vigorously by hand, if the plastering layer of the wall continues to drop ash, it means that its curing strength is poor, and it is recommended to remove it.

3. If there is hollow delamination in the relevant treatment layer of the wall, the water resistance of the putty is good, the curing strength of the plastering layer is good, but there is hollow delamination locally, it is recommended that the local area of the hollow drum be removed and reprocessed.

It is best to carry out the demolition, which is as follows:

If the wall of the original rough house is a cement wall, this kind of wall does not need to be demolished, and only needs to be directly carried out on the wall in the later stage of the process operation of standard wall coatings such as glue, putty, and grinding;

If the wall of the original blank house is white or white, it is best to remove it until the cement wall is exposed, and then the standard process of wall coating is made, for the following reasons:

1.The putty of the original wall is not made in the standard process, and the workmanship is not up to standard, so it cannot be directly brushed on the surface for operation, so it needs to be removed;

2.The putty of the original wall, due to the long construction time, the dryness of its moisture is relatively dry, and the paint brushing on it can not ensure its long-term quality assurance, so it needs to be removed;

3.The putty on the original wall, due to the long construction time, the surface may fall or be contaminated with floating dust, so direct brushing of the paint may affect its appearance and quality, so it needs to be removed.

When decorating, the original putty on the wall of the blank house must be removed, don't save this money, be careful because of small losses.

To determine whether it is a putty that meets the water resistance standard, its function is waterproof. If it is not met, it must be eradicated. If you don't shovel it, the paint will peel off and become moldy.

Depending on their own situation, most people will choose to shovel off the putty that should be annotated with talcum powder for most putty. If your house is annotated with white cement, you can choose not to shovel it, if it is talcum powder annotated for a year or two, there is not much problem, but there will be cracks after the year.

It must be eradicated, and if there is a problem, it will not only be labor-intensive, but also costly.

Just handed over everyone into their new home feels very spacious, bright and clean and tidy, and then go to see the neighbor who has started to remove the wall skin, the original cement structure is displayed very ugly, so the owner will involuntarily whim: my family does not shovel the wall skin, you just paint it!! Is that the right decision?

Let me be verbose here: the wall is a layer of putty when we hand over the house, not the paint, I believe most of you know, as for whether the wall skin should be shoveled, this must first start with the putty:

Putty: It is a decorative condensation material used to level the wall, and it is an indispensable product before paint painting to remove the uneven defects on the surface of the coated object.

There are generally two types of putty for building interiors: water-resistant type (N-type) and non-water-resistant type (Y). The main difference between the two is in the degree of firmness.

Water-resistant putty requires cohesion to be achieved under normal conditions, and the cohesion is achieved after 48 hours of immersion in water, while the firmness of non-water-resistant putty is achieved under normal conditions.

The main component of non-water-resistant putty is: white lime basically has no water-resistant type.

The main components of water-resistant putty are: heavy calcium, gray calcium, ultra-fine filler, water-resistant putty has better water resistance and corrosion resistance compared with non-water-resistant putty, like this non-water-resistant putty even under the premise of paint film protection its service life is only 5 years at most, and water-resistant putty has a service life of more than 15 years under normal circumstances.

From the beginning of industrial non-water-resistant putty to water-resistant putty to the third generation of ecological putty, due to people's higher and higher requirements for quality of life, the selection of putty is becoming more and more demanding!

The so-called third-generation ecological putty is also a negative ion wall lining on the basis of the original water-resistant putty added tourmaline gemstones, its existence can allow the room to permanently release a high concentration of negative ions, to actively purify the air formaldehyde and other harmful gases

In the decoration process, shoveling the wall skin and scraping putty are two different processes. The owner of the old house can understand the behavior of shoveling the wall skin and scraping putty. The operation of shoveling the wall skin and scraping putty in the new house makes the owners wonder.

Shovel the wall skin and scrape putty to repaint the wall of the old house to rejuvenate the old house. Some of the ground floors of the new house are not treated in place, and the wall skin is painted without shoveling, and soon, the wall paint of the new house will fall off in a large area. Affect the use of residents.

Shoveling the wall skin is to shovel off the surface layer of the current wall skin, and then scrape the putty for new decoration. When the owner is not sure whether to shovel the wall skin of the new house, he can use a wet towel to wipe the wall several times at a point, and wipe out the cement wall of the base layer to indicate that the wall needs to be shoveled and redone. Only by shoveling the wall skin can the wall be cleaned so that the subsequent putty scraping work can be carried out smoothly, and the scraped wall surface will be clean and beautiful.

After the original putty and paint covered by the base layer are cleaned, the cement or sand ash at the bottom layer is checked to have no cracks and is firmly finished, and the putty scraping process can be carried out. If the bottom layer is unqualified and the sand is loose, you can choose to continue to shovel the wall or paste the mesh cloth; If there are cracks, you need to patch the cracks with plaster before applying a bandage.

After the end of shoveling the wall skin and scraping putty, the work can begin. The putty used for scraping putty needs to choose a putty that is resistant to water and has a long service life, and the amount of putty is moderate when adjusting the putty, and it should not be too dry or too wet. Scrape two or three times repeatedly, scrape flat, and then sand smooth.

When scraping putty repeatedly, the first time should wait until a certain dryness before applying a second layer of putty. If the scraped putty beam fails, it is necessary to pay attention to the maintenance of the ante source, and if it is not completely dry, you can close the doors and windows, and place the best wall skin or unused putty to dry and crack. When scraping putty, find out whether there are impurities in time and deal with it cleanly.

This is followed by painting, with the first primer on the walls and the second and third coats.

The two processes of shoveling the wall skin and scraping putty are completed in accordance with the required standards, and the scraped wall is smooth and beautiful, making the overall decoration of the owner more perfect.
