What are the precautions for wall polishing and what details need to be paid attention to

1. What are the precautions for wall polishing?

1. Whether it is day or night, when the wall is polished, in order to be able to observe the flatness of the wall at any time, you must hold a light bulb of at least 200 watts.

2. The choice of wall sandpaper, not the coarser the better, nor the finer the better, generally start with the fine sandpaper, and change the coarse sandpaper if you can't move, but in the end, you generally have to use fine sandpaper to re-polish it again to ensure that the wall is meticulous and free of scratches.

3. In order to improve the service life of the owner's wall, a good construction master will recommend the use of water-resistant putty. However, water-resistant putty will be slightly more difficult when polishing the wall, so some black-hearted construction parties often refuse to use water-resistant putty under various excuses, and everything is only from their own savings, not for the owner. When scraping putty on the wall decoration, you must choose the best water-resistant putty.

4. Water-resistant putty is best polished within 3 days after being put on the wall, at this time, the strength is low, the surface structure is not firm, and it is more labor-saving to polish.

5. After the putty is completely dry, the bonding strength is higher, the surface structure is firm, and it is more difficult to polish. In order to achieve better results, you can first use 120 mesh coarse sandpaper to polish the first time, and then use 360 mesh or more fine sandpaper to polish the second pass.

6. The bonding strength of putty directly determines the future service life and water resistance, and if conditions permit, the long-term cost performance of water-resistant putty with higher bonding strength is higher.

Second, the wall putty grinding steps.

1. Putty grinding steps: grinding tools. Light bulb: Whether it's day or night, when sanding the wall, be sure to hold a light bulb of at least 200 watts in your hand in order to be able to observe the flatness of the wall at all times.

2. Sandpaper: The choice of sandpaper on the wall is not the coarser the better, nor the finer the better, generally start with the fine sandpaper, and change the coarse sandpaper if you can't move, but then you generally have to use fine sandpaper to re-polish it again to ensure that the wall is meticulous and free of scratches.

3. Manual sanding rack: The sanding rack is used to fix the sandpaper, which is convenient for operation and polishing. The putty polishing of the yin and yang corners also requires the use of a special yin and yang angle hand-sanding sand frame. If you use a machine to grind, you need to use a putty grinding machine.

4. Grinding time. Generally, cement-based water-resistant putty is better to be polished within 3 days after scraping on the wall, the strength is low, the surface structure is not firm, and the grinding is more labor-saving.

5. If the putty is completely dry (after 7 days), the bonding strength is high, the surface structure is firm, and it is more difficult to polish. If the strength is high and the grinding is difficult, in order to achieve better results, Uncle Craftsman suggests that you can use 120 mesh coarse sandpaper to polish the front pass, and then use 360 mesh or more fine sandpaper to polish the second time.

In wall implementation, the wall needs to be sanded in order to make the wall smoother and more delicate, which is an important part of creating a high-quality home decoration effect. So,What are the precautions for wall polishing?Well, if you don't know, you must do it.

1. Always observe, grinding means that after scraping mud on the wall to make the wall surface is flatter, the surface is more detailed and uniform, and the putty is polished. Polishing the wall not only involves the flatness of the wall, but is also an important solution to some minor defects in the means of wall decoration. When polishing the walls, use a light bulb of at least 200 watts to see if the walls are flat.

2. For the selection of sandpaper and putty, start the test with fine sandpaper, and replace it with coarse sandpaper when not moving, and then polish it with fine sandpaper again to ensure the fineness of the wall; While waterproof frankincense is more difficult to polish, it is beneficial. Improve the life of the wall. We had to choose to use putty with higher bond strength.

The joints of the putty determine the service life and waterproofness of the wall. As a result, water-resistant adhesives with higher bond strength are cost-effective in the long term.

3. Putty grinding, waterproof putty is well polished within 3 days after applying the wall. At this time, the resistance is low, the surface structure is not strong, and the polishing is more laborious. When polishing, keep an eye on the smoothing time on the wall** from time to time to judge that the polishing and grinding strength should be moderate and wide.

The second pass should be after polishing the putty completely dry (after 7 days), the adhesive strength is high, the structure of the surface is firm and grinding is difficult. What are the precautions for wall polishing?For better results, you can sand with 120 mesh sandpaper first, and then with 360 mesh or finer sandpaper.

4. Cleaning and construction inspection.

1) Clean the footline and some excess marks.

2) Check whether the color of the wall is uniform, if the color of the painted surface is consistent, and quality defects such as background, lack of brushing autumn alkali, formation of foam, bites, falls, etc. are not allowed.

The above is:What are the precautions for wall polishing?There are also some small details to explain, you can see more professional and better construction when you implement.

Although the main function of putty is horizontal, there is only a large amount of putty, only half of the work, and the other half, also determines half of the final effect, which will be solved by polishing. This is also the main function of wall polishing.

So first of all,Methods of sanding the wallsWhy is there a polishing item?

Methods of sanding the wallsIn the process of scraping putty, some small defects will inevitably appear, such as the joints at the joints of the putty, the marks left by some scratches or too thick, and the holes caused by water absorption. Walls and other walls have been polished by macro chain to solve the problem.

The surface structure of all the ground putties is more uniform, which can improve the performance of the latex paint and avoid some problems caused by structural differences. Surface.

Secondly,Methods of sanding the wallsWhat tool polishes walls?

There are two tools here: one is a light bulb and the other is sandpaper.

In order to be able to observe the flatness of the walls at all times, the staff usually have a light bulb in their hands, day or night.

Choosing sandpaper to polish putty is a concern for everyone. Methods of sanding the wallsTalk about it here.

The sandpaper is too thick and easy to scratch. The sandpaper is too thin and difficult to polish. Therefore, the choice of sandpaper for the walls is not as thick as possible. It is not as thin as possible, but it is better to match the wall putty.

On the premise of ensuring the flatness of the wallMethods of sanding the wallsIf coarse sandpaper is used, it is usually necessary to sand all or part of it with fine sandpaper to remove scratches from the coarse sandpaper and make the wall more detailed.

According to the quality of the putty. Due to its loose surface structure, non-waterproof cement is easy to sand. Usually, it is made of sandpaper of 240, 320 or higher.

However, due to the poor quality of most non-waterproof masking putties, the powder itself usually has low meshiness. Even with high-quality sandpaper, it is difficult to produce a very detailed feeling. The structure of the surface of the water-resistant adhesive is relatively strong and more laborious to grind putty without waterproofing.

It's hard to wait until the putty is completely dry and then sand. At this time,Methods of sanding the wallsYou need to use coarse sandpaper to complete the leveling, and then use fine sandpaper to sandwork a second time.

The wall should be eliminated: the old wall must be done before the renovation of the wall or material treatment, the layer is more serious to be eliminated, after the removal in the white concrete, if the original wall is too smooth, painted or painted must be cleaned up and polished. It is also necessary to remove the unstable surface and dust, which is conducive to the bonding of new industrial coatings and walls.

There is a peeling recess into the part of the good interior wall putty powder to make up for it.

Paint can not be less: the role of wall primer is to resist alkali primer moisture, seal the board, maintain the paint, and improve the three-dimensional sense and adhesion of the paint. Especially for the renovation of old houses, the walls must be painted, and the walls are easy to bubble and mold, and the color of the wall paint is easy to cause changes after a long time.

Repair should be multi-faceted: the repair of the painted wall is relatively unable to achieve satisfactory results, so the repair of the painted wall is a whole wall, or choose a very large area for repair, which can minimize the color cast.

Repair and anti-color shift: pay attention to the configuration and painting according to the instructions of the paint bucket, so that the demand may be good, and it is particularly important to prepare a sufficient amount at one time, so as to ensure that the color is the same. Although the paint company has added a color card comparison table, because the old wall itself is very alkaline, the expected effect is very likely to be different.

Pay attention to natural ventilation: In old houses, the air circulation norms are poor, and the xylene content in the paint thinner will cause a chemical reaction with the components in the wall paint, causing the wall to turn yellow. Therefore, it is important to improve air circulation and install an electric fan.

The walls have a tiny white powder, indicating that the salt in the walls is being treated during the drying process of the concrete"Carry out precipitation"At this time, you can use a soft brush or an iron brush to brush it off, and after a few days of observation, it is determined that it is not easy to develop white powder for precipitation, and wait for the cement wall to dry, polish and polish, and then paint. If there is a lot of white powder on the surface of the red brick wall and it is constantly precipitated, after it is eliminated, you can first apply a wall paint to avoid salt erosion in the future and cause wall cancer; 2. Do not use water-soluble industrial paint or weathering layer wallpaper to paint or decorate the house within three months.

If there is a problem of cracks and uneven walls, we must pay attention to the specific situation of the wall and the thickness of the wall during the polishing process.

During the renovation process, the wall shape should be sanded. You should choose the right material, scrape putty first, and then apply a good-looking latex paint, which will be more beautiful.

Buying a home is a big deal for most people, but renovating a home is just as important. Newly renovated houses will begin to age after more than a decade, and the style will gradually fall short of the times. At this time, we need to renovate and polish the walls to make our lives more comfortable.

What do you need to pay attention to when renovating and polishing the wall?

1.Darkening of the walls: In addition to natural oxidation, there are some unavoidable problems such as smoking, cooking, etc.

2.Peeling of walls: aging, dampness can occur.

3.Wall mildew: For a long time, because of the humidity and impermeability of the house, the walls will become mildew, and the edges will change color.

4.Bear Child: It's something we can't avoid. There are children at home. What we like the most is the variety of graffiti, which makes you angry.

This shows how important wall decoration is, and there will be a lot of wall decoration, see if you need it, and today we will bring you some tips on wall decoration!

1.Paint latex paint: Repainting latex paint is usually the first choice for most people to renovate their walls, but for this job, there are two things we need to be aware of.

For old walls with a foundation *** (no skin, no mildew, etc.). Many construction crews will opt for direct painting, but that's wrong! The old walls are smooth and hard, and the adsorption knots between them are very poor.

It is easy to peel the skin in a short time, and the wall renovation and polishing need to pay attention.

Do: Polishing the wall thoroughly, turning it to rough its surface, and then starting to polish to achieve maximum adsorption between the latex paint and it.

2.For old walls with poor foundation quality (peeling, dusting, obvious cracks), sanding cannot be saved. At this time, we need to completely eradicate the old wall, re-batch the putty, and wait for the putty to dry before painting the latex paint.

Note: A lot of dust is generated during these jobs. It is recommended that the little partner move or pack furniture and household appliances before work to prevent dust from entering.

The above are the matters that need to be paid attention to in the renovation and polishing of the wall and the problems encountered in the decoration process, I hope it will be useful to you.
