How to renovate the wall and how to deal with the renovation of the wall

Hello! We are the best home improvement consultant of Zhejiang Antke Technology:

1: When doing renovation, the previous wall must be cleaned, and the serious chalking must be eradicated. Because the previous wall has been brushed with paint and latex paint, it must be sanded after the shoveling, and all the skin and floating dust on the original wall will be cleaned up.

2. Primer is indispensable.

The main function of the wall primer is to resist alkali and moisture, seal the substrate, protect the topcoat, improve the quality of the topcoat and the hiding power. Especially when renovating an old house, the primer is important, if it is directly painted, the wall is easy to blister and mold, and it will soon fall off again.

3. Repair should be comprehensive.

In the process of repair, we must ensure that it is comprehensive, otherwise it will be difficult to achieve the expected effect if the repair is completed after the painting project is completed, and the big problem is that it will lead to color difference, so it must be done carefully and comprehensively when repairing, and do not cause a burden for the subsequent project.

4. The topcoat should be evenly proportioned.

Before the paint is painted, the paint should be painted according to the instructions of the paint barrel, and a sufficient amount should be prepared to ensure that the color is the same. When brushing the topcoat, you should choose the best paint roller, so that the texture of the brush will be more uniform and good-looking. Pay attention to ventilation after painting, because the xylene component in the thinner will react chemically with the component in the latex paint, causing the wall to yellow.

5. Ventilation should be done after renovation.

The renovated second-hand house should also pay attention to ventilation, especially for the old house, which has poor ventilation conditions, and the xylene component in the diluent will react chemically with the components in the latex paint, resulting in yellowing of the wall. Therefore, after the renovation of the wall of the second-hand house, it is really not possible to strengthen the ventilation, and a few electric fans must be placed to strengthen the ventilation effect.

Hope it helps you Hope!

According to your actual wall situation and your psychological expectations. The original wall is latex paint, and if you want to be economical, you can directly brush the latex paint again. The wall is wallpaper or wall cloth, you only need to tear off the original wallpaper wallcloth, leave the base film at the bottom, and glue the new wallpaper and wall cloth.

It's very simple, find a renovation company and you can give you satisfactory results.

After living in the house for a long time, the wall will be easy to have problems, especially the wall that has been scraped with putty, so many people choose to renovate the wall of the old house, but many people do not know how to deal with the renovated wall.

How to deal with renovated walls.

1. Treatment of wall base layer.

The wall surface of an ordinary old house generally needs to be removed by spraying the surface with water first, and then using a mud knife or planer to remove the surface paint; If it is for the old wall that has been in disrepair for a long time, the surface has been seriously peeled off, and the ironing layer is silty and sandy, the paint layer and the entire ironing need to be removed until the cement or brick layer is seen; Then use double fly powder and cooked rubber powder to mix the primer and flatten, and then finish the latex paint, the surface layer needs to be coated 2 to 3 times, and the interval between each time is better than 24 hours.

2. Brush latex paint.

Usually the second-hand house is used to treat the surface layer of the wall chain Huai wall, leveled with putty, polished smooth and flat, and then brushed with latex paint, which is the mainstream of wall treatment at present. The junction between the upper part and the top surface is made of gypsum line, and the junction between the lower part and the ground is closed with a baseboard. You can decorate it by hanging picture frames, **, tapestries, etc., with a shed and a simple friend with spotlights.

3. Paste wallpaper.

After the wall surface is flattened, the wallpaper is paved. If the wallpaper is old, you can remove the surface layer and no longer need to deal with it, just paste the new wallpaper, which is very convenient.

4. Tile pasting.

One of the main problems in tile decoration is the treatment of the waterproof layer. This is because there is a problem with water in most of the places where the kitchen and toilet are used. Therefore, the waterproofing of the wall should be paid more attention. New houses that have not been waterproofed or old houses that need to replace porcelain tiles need to be re-waterproofed.

The main treatment method of the waterproof layer is: professional waterproofing agent should be used for the ground and wall height of 1 meter, such as No. 911 waterproofing agent. The position of the wall higher than 1 meter can be waterproofed with cheaper asphalt oil.

If the economy is not sufficient, you can also directly use asphalt or resin to make the ground waterproof. The ground and the position of 20 cm on the ground must be thicker, and after the decoration is completed, try to avoid drilling holes in places below 1 meter height.

How to deal with wall renovation: 1. Base treatment: Before construction, the previous wall must be cleaned up, and the pulverized area should be removed.

2. Brush the environmental protection interface agent: after repairing the base layer, the wall should be brushed with the interface agent first, and then batch the putty after the interface agent is dry to ensure the close adhesion of the new coating and the original base layer, so as to avoid problems such as shelling and cracking on the wall after painting. 3. Batch scrape putty powder twice:

The function of batch putty is to fill and level, enhance the whiteness, and the wall of the second-hand house renovation is best scraped three times. Putty with a hard texture and fine particles is easier for the wall to be flat, smooth, and firm. At room temperature of 25°C, after the first putty is scraped, the second time can be scraped at an interval of 4 hours.

After the putty is dry, sandpaper is used. Finally, clean the wall thoroughly to avoid affecting the adhesion of the latex paint due to too much dust. 4. Apply a primer:

Be sure to apply another layer of primer before applying the topcoat. I believe we all have a certain understanding of the role of primer, it is mainly alkali and moisture-proof, sealing the substrate, protecting the topcoat, improving the quality of the topcoat and covering power, in addition, if the paint is directly applied, it will affect the appearance and feel of the paint film, and may also cause problems such as chalking. The primer should also be applied evenly.

5. Apply the topcoat twice: After the primer is dry, polish it with 400 sandpaper, and then paint the topcoat, try to complete one wall at a time to avoid joints. The role of the topcoat is to protect and decorate the wall, and the adhesion is more dense.

The second coat must wait for the first coat to dry completely, at least 2 hours at room temperature of 25°C. The latex paint will dry after 4 hours after painting, but the dry paint film has not yet reached a certain hardness, which should be cured, and there should be no scrubbing or any contact with the wall within 7-10 days. This answer applies to most wall renovation situations.

1. Waterproof and mildew-removal.

If there is mold on the fake wall, it is recommended to peel off the original wall until the base is exposed, make a waterproof layer from the bottom to the top, and then paste the tiles.

2. Repaste the wallpaper.

If the base of the wall of the second-hand house has been aged, it is recommended to apply the wallpaper after the process of plastering cement mortar, plaster leveling, scraping the wall lining, and painting.

3. Paste new tiles.

When the wall of the bathroom needs to be paved with porcelain and smiling bricks, during construction, the wall above the wall skirt should be shoveled off the outer layer to the base, and the cement mortar should be pasted after imitating plastering.

1. The renovation of the old wall is done by yourself, first soak the wall with water, so that it is more labor-saving when shoveling the wall, and the wall must be shoveled to expose the cement mortar surface. Then there is the application of the interface agent, which must be all brushed and evenly. Cracks in the wall are usually covered with kraft paper tape and white latex, but there is no guarantee that it will not crack 100% again.

2. If the wall is uneven, then it is necessary to use plaster to level it, and the error should not exceed centimeters. Non-load-bearing walls generally need to be patched, so it is best to choose wall cloth and white latex with good texture, and if possible, you can use mesh cloth, which will have a better anti-cracking effect. 3. When selecting putty, you should choose one with high particle fineness and hard texture, or add white latex to putty to improve the hardness of putty.

If the sandpaper is too thick, it will leave deep sand marks on the wall, and even if it is painted, it cannot be covered. The wall should be cleaned after sanding, otherwise too much dust will affect the adhesion of the paint. 4. When the wall is painted with primer, it must be brushed in every place and evenly.

Use a good texture roller to brush the primer, so as not to affect the effect of the primer painting. After the putty is sanded, the wall will leave some unsightly pits, especially after painting, which are very obvious, so they need to be repaired. Be sure to polish and smooth when making up, and add a little more water to the primer in order to avoid color differences.

1. After treating the old wall foundation, apply a layer of white cement. The original wall surface is too smooth and must be sanded after painting, and the previous unstable skin layer must be cleaned, so that the new paint will be more viscous. 2. The main function of the wall primer is to prevent moisture and protect the topcoat, which can improve the texture and hiding power of the topcoat.

If it is an old house renovation, you need to apply primer on the wall, if you don't paint it directly, the wall will be easily damaged after a long time.

1. If the wall has been painted, it will be more difficult to repair, and it is easy to have color difference, and it will become a large flower wall in an instant. In addition, the wear time of the material is different, and the quality is difficult to guarantee, and it is difficult to achieve the desired effect. If the restoration process is not completed, it is more troublesome if the painting process is completed.

2. Before painting, install the paint according to the instructions on the paint bucket, and you must prepare enough to ensure that the color is the same. When brushing the topcoat, you should also choose the best paint roller, and pay special attention to the problem of ventilation after painting, because the thinner with xylene will react with the latex paint component to cause the wall to turn yellow.

3. The wall must be cleaned first, and the wall will have these problems such as chalking and cracking after a long time, and the wall with serious chalking must be removed.

First of all, clean the wall, apply primer, repair a large area, and finally follow the instructions of the paint bucket to mix and paint.

There are two main ways to renovate old walls: wallpaper and painting. The basic treatment of the old wall mainly refers to the removal of the original decoration and decoration of the wall.

Generally, it includes the removal of the original latex paint and putty layer on the wall, wood decoration, and the removal of other surface decorations. If the wall has only been renovated for one or two years, the water-resistant putty of the wall can be repainted without having to be completely eradicated, and the wall can be repainted with a steel brush and sandpaper. If the decoration time is longer, the putty layer needs to be completely removed, and the putty needs to be re-brushed before other processes.

Precautions for renovation of old walls:

1. While carrying out space transformation, it is necessary to understand the characteristics of the wall of the house, and the load-bearing wall must not be destroyed in the decoration, and some non-load-bearing walls cannot be demolished and modified at will, otherwise it will have a serious impact on the safety of the house.

2. The ventilation conditions of the old house are poor, and the xylene components in the diluent will react chemically with the components in the latex paint, resulting in yellowing of the wall. Therefore, to strengthen ventilation, open more doors and windows, or put a few electric fans to strengthen the ventilation effect.

3. Due to the aging of the material, the water-resistant putty of more than five years must be removed to the bottom of the wall during the second decoration, otherwise it will affect the construction quality of the wall latex paint and the long-term use effect after the decoration.

2-Priming, apply the curing agent on the wall 1 time to avoid problems such as peeling and cracking on the wall, and wait for the curing agent to dry completely before batch putty to let the old layer and the new layer bond together.

To do waterproofing, apply waterproofing agent to the wall to avoid mold on the wall again. Note that when applying the waterproof layer, you must wait for the first time to dry before applying the second coat, otherwise it is easy to have problems such as bulging.

First of all, let's take a look at the previous front.

If it's good, then brush it with a layer of latex paint on top.

If it is not good, you need to knock it down and redo the putty.

If there is no problem with the bottom of the wall, you can scrape the putty directly.
