In the decoration of second-hand houses, it is usually much more complicated than the general renovation of new houses, and there will be many more processes and steps, and there are also many problems that should be paid attention to in the actual decoration. Due to the complexity of the second-hand housing decoration workers, in the actual second-hand housing decoration, the owners must first know some related knowledge of second-hand housing decoration in advance. Today, Bian Xiao mainly introduces the main points of second-hand housing wall decoration and the matters needing attention in second-hand housing decoration.

Key points of wall decoration in second-hand housing decoration

1, brush latex paint

This is a simple and extensive decoration method in wall decoration. The general process is to fill the wall, level it with putty, polish it smooth, and then brush latex paint, which is a tributary of the current wall solution. The upper step and the top floor are connected by plaster lines in turn, and the lower part is connected with the sky by skirting lines. This solution is simple and obscure, but it can make the room more open. At the same time, you can hang wooden frames, photos, tapestries, etc. , combined with spotlights, increase the beauty of the wall.

Step 2 paste wallpaper

After the wall layer is solved, the wallpaper can be laid. There are many kinds of wallpaper, and there are different choices in color, style and material. It's easier to clean wallpaper when it's dirty. The new wallpaper can be gently wiped clean with a wet cloth. Moreover, it is easier to change the wallpaper. If you are not satisfied with the old wallpaper, you can change the style of wallpaper at any time, which will bring a fresh feeling to the room, and the price of wallpaper will not be too high, nor will it waste too much money. However, wallpaper is afraid of mildew and compactness, so before cutting and pasting hadrons, the base surface should be solved first to avoid mildew of wallpaper.

Step 3 place the plate

All the walls are paved with foundation boards and decorated with decorative boards, which will make the overall effect comfortable and fresh, but it will make the room appear crowded. However, if you have a whole wall made of boards such as MDF, but painted with red latex paint, the surface will not have the effect of boards. Because of the characteristics of the board, you can make curves, pits and other shapes with the help of the board, which will solve the problem of flat wall and exquisite shape and prevent the crowding caused by a small amount of board.

Ceramic tile is the scientific name of decoration materials at present, which is mostly used for indoor floors or walls. Because the advantage of ceramic tile is dirt resistance, in addition, the advantage of ceramic tile is better waterproof. Because the kitchen and bathroom use a lot of water, we should pay more attention to the waterproof of the wall. Because there are many styles of ceramic tiles, it is more suitable for the needs of owners who want clean and tidy walls. However, it should be noted that the reconstructed wall surface needs to be waterproof again when it is treated at the grassroots level.

Second-hand house decoration: 5 tricks to teach you to deal with old walls again

1, and then paste the wallpaper

If the original wall is waterproof putty, and the wall has high strength and is well preserved, you can paste wallpaper directly. If there is wallpaper on the original wall, remove it, polish it with fine sandpaper and coat it with protective agent, and then you can paste a new wallpaper.

The basement of the old house is a sand-gray wall, which will age over time. Even if you don't stick wallpaper, you should completely eradicate it, otherwise there will be cracks and skin exposure. Apply cement mortar, level with gypsum, scrape the wall lining, paint and paste wallpaper.

Tip: After the wallpaper is pasted on the wall, don't expose to the sun or be blown by the wind. Air-dry naturally, otherwise the gap will be obvious. When necessary, use curtains (curtain decoration renderings) and other items to block the sun.

2, waterproof and mildew proof

The long hair and mildew on the wall are mainly due to the humidity in the wall, and the moldy wall skin generally appears in the bathroom. There is more water in the bathroom, which will erode the wall after a long time. It is suggested that the original wall should be stripped out of the basement, waterproof layer should be made from bottom to top, and then tile should be attached.

Tip: If there is no moldy and hairy wall on the first floor of the basement, it is only recommended to lay floor tiles instead of floors.

Step 3 make a theme wall

If you want to make a gypsum-shaped theme wall, add a wood core or light steel keel to the original wall, and then make a gypsum shape on it.

If the original wall is a brick wall or a cement wall, it needs expansion screws to fix it; The light-weight wall is directly drilled to connect the gypsum molding with the light-weight wall.

Tip: Before 2000, most indoor walls of commercial housing were load-bearing walls. If you want to install a TV on a lightweight wall, do a reinforcement project.

Step 4 paste new tiles

There is no need to scrape putty and brush the wall tiles. After the cement is leveled, the tiles can be pasted after waterproof and roughening.

The internal structure of the old bathroom wall is generally 1.2m cement dado+sand ash. During construction, the outer layer of the wall above the dado should be shoveled to the basement, plastered with cement mortar and tiled. Otherwise, because of the poor plasticity of sand ash, the tiles will definitely empty and crack in the future.

Tip: The cement dado can be removed. Before tiling, the process of napping should be carried out, that is, small holes should be made on the cement surface, and then wall treasures should be used to improve the bonding ability between cement and tiles.

5, crack repair

There are generally four reasons for cracks in the wall: first, if the house is a high-rise townhouse, workers dig construction holes between the walls to transport building materials during construction, and then fill them with foam bricks or light bricks later. Remind the owner that there may be cracks between the foam brick and the wall, which will cause the wall to crack in the future; Second, it is also possible that when the house was just built, the putty was scraped too thick or brushed before it was dry. After a long time, reticulate cracks will appear, and in severe cases, the wall skin will fall off; Third, the exterior walls of some units face the road and are greatly influenced by the outdoor environment. Cement, sand and steel bars in the wall expand with the change of temperature, contract when it is cold, and cracks appear in the inner wall. Fourth, it will appear on the wall built later. Whether it is a large core board, lightweight brick or gypsum board, cracks will definitely appear in this wall within six months to one year, and it needs to be repaired later.
