Decoration company teaches you how to transform old houses in Chengdu?

PART 1: reconstruction of old house wall

As the saying goes, white covers all ugliness, so do people and houses. If the wall is painted again, the room will naturally be much brighter. In the secondary decoration, wall decoration is a big project. Due to the complexity of the wall, different materials and processes, it is more troublesome to deal with the wall. So, must all the putty be deleted? What are the precautions for wall decoration?

First of all, the wall paint "five years old" must be removed.

The old wall was torn down. The necessary work generally includes removing the original latex paint and putty layer on the wall, the original wooden decoration, and removing other surface decorations, such as wallpaper.

The removal of the original latex paint and putty layer on the wall is the basic structure that must be carried out in all secondary decoration. After 1990s, waterproof putty was gradually popularized and used in interior walls. It takes time and effort to eradicate waterproof putty, and it is easy for the construction team to cut corners at this stage. The owner can choose the craft according to the length of the house and the economic situation. If the room is only decorated for one or two years, you can remove all the waterproof putty and repaint the wall paint with steel brush and sandpaper. It should be noted that due to the aging of materials, putty that has been waterproof for more than five years must be moved to the bottom of the wall during the second decoration, otherwise it will affect the construction quality of wall latex paint and the long-term effect after decoration.

Second, the wall should be safe.

1, reasonable disassembly is for beautification and adjustment.

The wall can expand the living room or bedroom space, and the original wall can be replaced with new doors and windows. But the premise of demolition is to consider the overall structural safety of the house.

2. Non-bearing walls can be removed.

In the current residential buildings, the original design and construction of houses will be based on cost, structure and technology, and a large number of light walls will be used as the main body. In addition to the structure, the materials also include aerated concrete wallboard, ceramsite block wall, light steel keel gypsum board wall, hollow cement precast slab, magnesite cement precast slab and so on. In addition, according to the age of the building, some masonry walls such as red bricks and light bricks can also be demolished, but they must be handled with caution.

3。 Be sure to turn off the power supply in advance when tearing down the wall to avoid accidents.

For the original power lines and weak current lines to be preserved, it is best to mark and record them in advance, and leave enough allowance for the drilling of lines interrupted by construction for future wiring. The owner should slap the workers, and it is best not to cut off the video line and broadband network routing to prevent signals after renovation. Some walls near the kitchen and bathroom had better not be torn down. Demolition will destroy the integrity of the waterproof layer and affect the future safety.

Three, wall decoration should pay attention to five points.

1, the wall should be cleaned. The old wall must be done well before renovation, and the powder surface should be completely removed. White cement should be used again after eradication. . At first, the surface of the wall was too smooth. After the paint is removed, polish and remove the unbonded skin to promote the bonding between the new paint and the wall.

2. The primer is not a small size primer that can resist small alkali and moisture. It can seal the substrate, protect the topcoat and improve the texture and hiding power of the topcoat. In the renovation of old houses, the wall surface must be used as primer. If you brush paint directly, the future wall will be easy to bubble and shape. It is easy to change color when the sun shines for a long time.

3。 It is necessary to completely repair the painted wall. Relatively speaking, it is difficult to achieve the expected results. Therefore, it is best to repair the damaged wall, or try to choose a larger repair area to avoid color difference, and the quality after repair is better.

4. Repairing the anti-color wall surface leads to color difference, which should be avoided when repairing the wall surface. To this end, it should be noted that according to the description of the paint bucket, it is best to estimate the amount of paint. It is important to prepare enough materials at a time to ensure the consistent color of the wall. Although the paint factory provides color cards, the effect may be biased because of the strong alkalinity of the old wall.

5。 Pay attention to the poor ventilation conditions in the old ventilation room. The xylene component in the thinner will react chemically with the components in latex paint, resulting in yellowing of the wall. So we should strengthen ventilation. It is impossible to place several electric fans to enhance the ventilation effect.

Part II: Renovation of Old Houses

When the second-hand house and the old house are rebuilt on the ground, different ground materials need to be rebuilt and reloaded. Different floors will have different treatment methods. Among them, the renovation of tiles and floors is the most common. The following Chengdu decoration network will share with you the experience of ground decoration of second-hand houses and old houses.

First of all, partial transformation is not feasible.

The renovation of second-hand houses and old houses can be divided into two situations: demolition of the original building and no demolition of the old building. Which method to adopt depends on the damage degree of the old floor.

1, keep the old floor.

If the original floor is solid wood floor, and it is well maintained, you can consider not removing it, and reinforce or adjust the loose part on the basis of the original floor. If the original floor is a composite floor, the service life is less than 5 years. If the wear is not serious, you can continue to use it, but check the integrity and looseness of the floor.

2, the old floor renovation

The purpose of floor renovation is to polish, putty, paint, wax and polish the floor surface, so as to restore the brightness of the old floor and prolong its service life.

When polishing the floor, the sander should use 40 mesh, 80 mesh and 120 mesh sandpaper in turn (the larger the mesh, the smaller the particles of sandpaper, and the less obvious the scratches left by polishing), and then polish the putty to level the floor. Then, the floor is painted with color. The floor usually needs to be brushed once or twice. When the paint is completely dry, you can brush it again. So it usually takes 4 days to renovate the floor.

Second, rapid renovation has the ability to turn bricks.

The renovation of old floor tiles can also be divided into two situations, one is to eradicate the original floor tiles, and the other is to directly lay the floor tiles on the surface of the new old floor tiles. In addition, pay attention to the height of the ground and the height of the ground when renovating floor tiles.

1, demolition of old bricks

If the original floor tile is partially damaged, empty or falling off, the surface enamel is worn or seriously dirty, it must be removed and replaced.

2. Directly lay new floor tiles

At present, there are two kinds of brick wall renovation materials on the market: ceramic tile surface treatment agent and ceramic tile and mosaic adhesive. These renovation materials can be directly coated on the old brick surface, and then paved with new bricks, saving time and effort.

3。 Matters needing attention in floor tile renovation

When using wall tiles and floor tiles, debris should be avoided to block the sewer; The handle is waterproof, and elbows are used as little as possible to avoid water flow or blockage; Use boards as much as possible. Wood products contain formaldehyde, which affects health.

Third, pay attention to the ground leveling and decoration considerations.

There are many points for attention in the renovation of old houses, mainly paying attention to the leveling of the ground and avoiding wires. If it is uneven and the base is not firm, sand will return from cracks in the floor or along the corner after the floor is paved. It will affect the quality of the floor in the long run.

1, pay attention to the height difference.

It turns out that the house is tiled on the living room floor and bedroom floor. Tiled cement mortar will raise the floor, so that there is a distance of 2 cm to 3 cm between bedrooms. Difference. In order to change the decoration of old houses, the floor needs to be leveled before the bedroom is laid.

2, pay attention to the grounding circuit

When an old house is renovated or renovated, many families will make some circuit modifications because of adding sockets or changing the function of the room. Electric wires generally pass through the ground, and state regulations prohibit digging. This requires raising and leveling the ground, burying the pipeline in the ground with a leveling layer, and then laying the floor.

3. Leveling treatment under special circumstances

In some special cases, paving bricks also need to be leveled separately. For example, when the floors of bungalows and villas are laid in new houses, the ground treatment is rough, some floors tilt in one direction, and some pits are very serious. If there is no initial renovation, the old house needs to be demolished separately during the renovation.

The third part: the renovation of old houses' doors and windows.

Renovation of doors and windows is the key to the renovation of old houses. When dealing with doors and windows, the treatment method should be decided according to the aging degree of doors and windows. In addition, there are many details to be paid attention to in the renovation of doors and windows of old houses.

First, repair the damage with sandpaper.

If the surface of the wooden door is damaged, such as cracks or holes in some places, first put the damaged place in the damaged place, then polish it with sandpaper, and then brush the primer and topcoat.

If the base is not damaged, please consider painting directly. The correct way is to polish the original wooden door with sandpaper, and then directly apply primer and topcoat. Because the finished door is waxed, there will be grease on the surface. After polishing, the adhesion of the coating can be improved. There is no difference between the quality of decoration and initial painting, so don't worry about life shortening or other quality problems.

Second, the basic materials will not harm the overall situation.

One problem that everyone will pay attention to is the transformation of wooden doors. At first, wooden doors were painted or water-based coatings. If similar paint is not used in the decoration process, the quality will be poor. . Experts say this problem is not a problem.

Generally speaking, there are three kinds of paints, polyester paint, nitrocellulose and alkyd. Alcoholic acid paint is an early product, which takes effect slowly and is used less and less in decoration. Nitrocellulose paint dries quickly, but the paint film is very thin and needs to be brushed many times, so it is easy to turn white when the humidity is high. Polyester paint is widely used, with fast film forming speed and better effect.

If the original paint is used, please consider using the same paint or water-based paint. Generally speaking, except for polyester coating, the adhesion of the same coating is better. If you brush polyester paint first and then polyester paint, you need to melt the original paint film to obtain good adhesion. One of the problems brought by this renovation is that the adhesion between the renovated paint film and the original paint film is not very good. If the new film is damaged, such as cutting or pulling out the pit with a sharp tool, the two layers will peel off along the crack or pit. Waterborne coatings are relatively more environmentally friendly, and the decoration of wooden doors is mostly carried out indoors. Oily paint has a strong smell and is not volatile. I suggest you decorate with water-based paint.

Chengdu decoration company reminds: if the wooden door is decorated, the longer the first painting time, the better. Because the original substrate has been dried in the renovation process, it will not affect the re-coating. If you just buy wooden doors, it is recommended not to spray them first. Because if the smell is strong, it will not dry, resulting in poor adhesion of paint film.

Three, aging doors and Windows renovation matters needing attention

For the aging transformation of old house doors and windows, don't use aging doors and windows to save costs. The specific treatment method is as follows:

Deformed wooden doors and windows. This shows that the characteristics of wood itself have changed and must be deleted and redone. However, if the material is dense and the surface paint film is complete, the decorative board can be connected to the secondary structure for use.

The surface of steel doors and windows falls off, and the main body rusts or cracks. In order not to affect the use effect, it is best to delete the redo.

Fourth, dark oil is not easy to cover.

Because any base material and material can be refurbished, if crude oil is used and the color is dark, you can't use light paint unless the original color is covered with dark color. If it is mixed with oil at first, the color is not limited, and it can be changed to any color.

In addition, there are three points to pay attention to in the construction. For the film-forming effect, the quality and structure of the coating will have certain influence. Oily coatings are generally good, and normal construction is enough. Usually, in the construction of waterborne coatings, workers are prone to make the following mistakes, which will affect the construction effect.

1, not properly watered according to the instructions, and the amount of water exceeds a reasonable proportion, which affects the shooting effect;

2. Under normal circumstances, the primer can be brushed three times after being sprayed twice, but it takes 4-6 hours to brush the paint for the second time. Workers paint once every 2 hours as shown in Figure 1-2, and the paint film is not dry, which affects the final effect.

3. During construction, workers will use coarse sandpaper, but fine sandpaper will be used, with finer grinding and better adhesion.

Chengdu Decoration Company suggested that since the wooden door decoration is carried out indoors, it is best to remove the door and put it in a special room for spraying effect. No dust can reduce environmental pollution; Secondly, you can see the front and back of the door very clearly. If it is directly sprayed on the door, it is easy to generate fog when spraying, which will affect the line of sight and the spraying effect.
