The house will look old after living for a long time, because it is scraped with putty powder, so many people will renovate the old wall, so how to deal with the renovation wall of the old house? Let's take a look at it below!

1. Treatment of wall base layer.

1) Before the wall is renovated, the original paint surface should be cleaned, the wall can be sprayed wet with water, and the wall paint surface can be removed with an electric planer or a trowel.

2) If it is a wall that has not been repaired for a long time, the surface of the wall will have a relatively serious paint peeling off, or the plastering layer is silty and sandy, in this case, the paint layer and the entire plastering need to be removed until the cement plastering or brick layer can be seen.

3) After the wall is cleaned and late, mix evenly with double flying powder and cooked rubber powder, and then carry out priming and flattening, and then apply latex paint, and the latex paint surface layer needs to be coated 2 to 3 times, and the interval between each time is best more than 24 hours.

2. Brush latex paint.

If you only need to treat the surface of the wall, you only need to level it with putty, then polish it and then brush it with latex paint, which is the simplest and most common way to renovate the wall.

3. Paste wallpaper.

If it is paving wallpaper, then the wall needs to be processed and leveled first, and then paved, there are many types and colors of wallpaper on the market, and it is more convenient to construct, if it is dirty, it can be replaced at any time, and it is also very convenient to clean, but the main key technology of wallpaper construction is mildew prevention and dealing with the problem of elasticity.

4. Tile pasting.

Ceramic tile is also a relatively common wall decoration material, generally used in kitchens, balconies, toilets and other places, and is also a wall decoration material that is more resistant to dirt; However, when decorating ceramic tiles, it is necessary to pay attention to the treatment of the waterproof layer, such as the bathroom and kitchen where the water consumption is relatively large; If you use tiles for the renovation of an old house, you need to make a new waterproofing layer.

wall decoration"> decoration currently has these main methods:

1. Latex paint: at present, it is the most widely used, and it is also a way that can be used in a large area at home, which is convenient for construction, and has many colors, but it is generally impossible to achieve patterns and patterns. Water-based latex paints are more environmentally friendly, but there will inevitably be some volatile substances.

And at present, there is no latex paint that can truly resist scrubbing.

2. Wallpaper and wall cloth: It was popular more than 10 years ago, but at that time it was all plastic wallpaper, and the paving method was very unenvironmentally friendly, so that many people now have a grudge against it.

In recent years, some imported products have become popular again, this product is generally pulp + calcium carbonate as the base, the surface is paper or cloth, the outermost layer of polyester vinyl coating, the finished product of the brand is very environmentally friendly, generally almost no toxic substances, plus now the paving is commonly used special wallpaper glue, such as Henkel Medeland, Germany, this glue is made of potato rhizome extract, almost non-toxic and harmless.

And the biggest advantage of this kind of wallpaper is that it can be completely resistant to scrubbing, you can even remove the ink stained on it with a small brush with a washing spirit, and the wallpaper, both plain and colorful for people to choose from, is also very easy to replace, I think this is also the reason why it has been widely loved by young people in recent years.

3. Paint wall cloth + latex paint: the application is not very wide, it is a combination of wallpaper and latex paint, first pave a special wall cloth on the wall (the material is non-woven fabric or glass fiber), and then brush latex paint on it, so that the finished product will have the texture of the wall cloth, scrubbing resistance and anti-cracking effect will be stronger than the latex paint wall, but it is very expensive latex paint, the whole cost is high, and there is volatile pollution of latex paint, personal feeling is not as good as choosing wallpaper directly.

4. Ceramic tiles: more common in the wall decoration of kitchens and bathrooms and some public halls, not afraid of water, durable, and easy to clean.

5. Special decorations such as wood, glass, stone, etc.: generally used for some special walls, mainly to create some visual effects, and rarely used in a large area.

Brush paint:

The surface layer of the wall is treated, leveled with putty, sanded smooth and flat, and then brushed with paint, mainly latex paint. The junction between the upper part of the wall and the top surface is made of gypsum line (or wood molding), and the junction between the lower part and the ground is closed with a baseboard. This is the simplest and most common way to decorate your walls.

This treatment is simple and crisp, and the room appears spacious and bright, but lacks variety. It can be decorated by hanging picture frames, **, tapestries, etc., with spotlights. Now there are some new types of coatings, such as imitation silk paints, colorful paints, etc., which make the wall treatment methods more abundant.

Paste wallpaper: make murals:

After the wall is treated and flattened, the entire wall from the ground to the top is sprayed into a huge landscape painting, or the blue sky and white clouds, or the dense forest and clear spring, which can give people a sense of intimacy of returning to nature.

Wrapping wall skirt: from the ground to the top along the wall around the wall with a circle of about 1 meter high wall skirt, which can protect the wall from furniture and external force, easy to clean, and can also visually divide the wall, so as to play a decorative role. This decoration method is more common in Europe and the United States, and is mainly suitable for tall rooms.

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 in the future and the long-term use effect after decoration.

The ventilation conditions of the old house are poor, and the xylene component in the thinner will react chemically with the component 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.

Whether it is wall paint, wall tiles or wallpaper, if you want to renovate better, you should reprocess the base part of the wall. If you want to demolish and modify some walls, then you should pay attention to the treatment of load-bearing walls.

1. If the wall of the old house is painted, if you want to repaint it, you need to shovel the wall skin, and we can stain some water on the wall to be renovated. Wait until the water is soaked before you start working. When shoveling the wall skin, you can do it until the cement sand wall or putty layer is exposed, and then brush with a layer of surfacing agent.

2.The next step is the treatment of wall problems, such as wall cracks, leveling, plastering, etc., for the treatment of some cracks. We usually put kraft paper tape stained with white latex to stick to the cracks, and if the wall is uneven, we need plaster to repair it.

The patch is generally used for the process required by the lightweight wall, which can not bear the load, and the best patch is the mesh cloth, which can effectively prevent the wall from cracking. 3

The next step is to sand and brush the primer, you need to use finer sandpaper, and you must clean the wall after sanding, so as not to absorb too much dust and affect the next step. After the grinding is completed, it must be inspected, and if there is any unevenness, it should be remedied in time. 4. Brushing the primer is the same as brushing the interface agent.

Every place should be evenly brushed, and the quality of the primer must be the best. The best of the primer can ensure that the service life of the wall paint is longer. It is also a kind of protection for the wall, the last step is to paint the wall, the roller of the wall paint must be meticulous, and the hair can not be too short, so that the wall can be delicate enough, and the feel will be good.

It is best to use an edging roller for painting. 5

Or you can put wallpaper. To paste wallpaper, you also need to scrape putty first. Then apply the primer. Professionals call it the base film, the base film can prevent the wall from getting wet, and after a day, the base film can be pasted with wallpaper.
