What are the things that need to be paid attention to in the process of renovating and polishing the

The wall should be removed: the old wall must be solved by the wall substrate before renovation, and the delamination must be removed if it is more serious, and the pure white concrete must be covered after the removal, if the original wall is too smooth, painted or the wall paint must be cleaned up and polished to solve the problem. It is also necessary to remove the surface layer and dust that are not firmly bonded, so as to facilitate the bonding of new architectural coatings to the wall.

There is a part of the concave that has peeling, and it is good to have putty powder to make up for it.

The role of the wall primer is to resist alkali primer waterproofing, seal the board, maintain the paint, and improve the layering and adhesion of the paint. Especially for the renovation of old houses, the walls must be painted, and the walls are very prone to bubbles and mildew, and the color of the wall paint is also very easy to change after a long period of sunshine.

The repair should be all-round: it is relatively difficult to achieve satisfactory practical results for the repair of painted walls, so it is better to repair a whole wall for painted walls, or try to select a relatively large total area to carry out repair, which can minimize color cast.

Repair anti-bias color: Pay attention to the preparation and brushing according to the instructions of the paint bucket to estimate the amount used, and it is important to prepare enough amount in advance to ensure that the color tone is the same. Although the paint company has brought a color card comparison table, because the old wall itself is very alkaline, the actual effect is likely to be different.

Pay attention to ventilation: The standard of natural ventilation in old houses is weak, and the xylene content in the paint thinner will change chemically with the chemical composition of the wall paint, causing the walls to turn yellow. Therefore, it is necessary to strengthen natural ventilation and install an electric fan.

The process of renovating the wall of the old house:

Removal of the wall: The wall has a fine white powder, indicating that the salt in the wall has been used in the drying process of the concrete"Precipitation is performed"At this time, you can use a soft brush or iron brush to brush it off, and after a few days of observation, it is clear that there will be no white powder to precipitate, and the cement wall will be dry and polished, and it will be painted. If there is a lot of white powder on the surface of the red brick wall and it continues to precipitate, after removing it, you can first apply a wall paint to prevent salt corrosion and wall cancer in the future; 2. Do not apply oil-soluble architectural paint or waterproof wallpaper brushing or interior decoration within three months.

Remove the peeling paint layer: Use a knife or iron brush to remove the paint layer from the peeling wall, and then sand the surface layer with sandpaper.

Renovate the surface layer: plug the pits and crevices with a soil knife until it is fully dry, and then polish it with sandpaper.

Solve the wall disease: The lesion is likely to have dirt, blistering, cracking, flaking or delamination, etc., which need to be solved.

Lacquered above:"Primer"Architectural coatings are specialized in the boundary layer that does not need to be solved for walls, and for the boundary layer that has any problems, it is necessary to first select a unique and unique problem"Topcoat"。

Upper paint: that is, general paint, use a stick to stir the architectural paint evenly before applying.

Painting: The process of painting is to gradually brush from the ceiling and then downwards, so as not to cause the paint dripping from the ceiling to decorate the finished walls.

The first point that needs to be paid attention to is some decoration of the entire wall of the old house, the second point should be noted that the waterproofing of the bathroom must be done very well, and the third point should also pay attention to the friction of the wall, and the choice of this color is very important.

It is necessary to check the damage to the wall, the waterproofness of the wall, whether the wall is firm, whether the paint in the corner of the wall is serious, and the condition of the moldy wall.

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.

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.

3. Putty treatment.

Before scraping off the mastic, a ruler should be used to check the flatness of the wall, and during the construction process, the irregular area should be scratched several times until the uneven area is repaired.

After the construction of the finishing layer, it must be taken into account that the two structures must be separated long enough for the paint surface to dry naturally. Finally, we recommend that you choose *** rollers for better brushing.

5. Window ventilation.

Generally speaking, the repaired wall will be exposed to harmful gases, which can easily affect human health. Therefore, after construction, regular ventilation of the windows is required, which also helps to speed up the drying of the walls. Of course, you can also use an electric fan to improve indoor ventilation.

6. Grinding and cleaning.
