【 Weak current College 】 common repair construction technology (1)

We here mainly on direct wall decoration, with regard to rely on the wall of furniture, etc, please see the section about the furniture.

Wall decoration, mainly: latex paint, paint, wallpaper (cloth), ceramic tile, wood veneer, AICD, gypsum template. Wall, there is in operation, the former has to practice as a deciding factor. But certainly, tile finishes in will be done after the ceiling, and latex paint and so easy to get dirty, usually in the back. Next, let's look at some common practices:

I. latex paint

Very popular decoration. You can reference the author wrote the chapters on the paint to the details view. LaTeX is the wall surface processing.

In the second decoration, coatings and finishing before the original paint layers of processing based on the following three principles:

1, new House wall generally only need to use coarse sandpaper, does not require the original paint layer.

2, normal, old house walls in general need to eradicate the original paint. Method is used to water the surface first, and then sprayed wet clay cutter or electric Planer machines to its eradication in surface finish.

3, for the run-down old walls, the surface has a serious paint peeling, burning layer solid powder sandy, need to paint layers and the entire batch of hot eradicated until see cement burns or brick layer.

4, and then use a pair of powder and cooked powder mixing ingredients "batch ping, then finish latex paint, surface desired coating 2 times to three times, each time interval between the time in 24 hours.

Necessary to remind that, many industrial coatings are more or less toxic, during construction, construction after ventilation to at least a week or more time volatile can stay behind. So as not to cause damage to the health of their families.

2. spraying

Spraying building decoration industry spraying was used in the building exterior wall surface processing technology, mudskipper could form a variety of colors, textures, three-dimensional sense of elegant effect. Due to the construction of the construction method of spraying, can greatly shorten the construction period. So soon extended to the interior decoration project. In some cities, decoration companies have begun to use the spray approach to wood coatings (varnish, contamination) and latex paint for wall. The use of tools based on the principle, they are divided into a gas spray and Airless spraying.

There are gas spray, also known as low voltage pneumatic spraying, it relies on low pressure air to paint in spray out after the formation of spray gun airflow to the surface (a wall or wood surfaces). There are gas spray relative to hand brush, the brush marks, and plane relative uniform, work time is short, units can be effectively shorten the duration. But there are gas spray, splash of paint waste exists. In close-up view, visible very fine granular. Generally there are gas spray with decoration industry common air compressor, relatively speaking, multi-purpose a machine, the investment cost is low. The market also has a suction-type pneumatic spraying machine, since the fall of a gas spray machine dedicated machines.

Airless spraying, also known as a high-pressure airless spray, it uses high-pressure plunger pumps make paint in spray out gun formation atomization air flow to the surface (a wall or wood surfaces). Airless spraying relative to have gas spray coating, paint surface evenly, no sense of particles. But Airless spraying equipment relatively expensive, only a very small number of professional paint companies have such a device. Airless spraying can be used for the construction of high viscosity paint, but edge is clear, even for some border requirements of spraying projects. Depending on the type of machinery, also divided into pneumatic Airless spraying machine, electric Airless spraying machine, internal combustion-gas spray spraying machine, etc. In addition, it should be noted that, if on metal surfaces for painting treatment, it is best to use metallic paint (enamel).

Third, wallpaper

The decoration is quite common. Main paper maker wallpaper, chemical fiber wallpaper, plastic wallpaper. While generally known as the fabric of wallpaper, not as wallpaper redbud will.

Images can be printed pattern, pattern, color rich, varied and the construction convenience is quick.

Wallpaper of construction, the most important key technology is mildew and handle scalability problems:

1) fungicidal treatment. Wallpaper posted before, you need to first base to handle, you can fly powder with cooked powder for batch hot leveling. It dry, then brush on a couple of times of varnish, and then again to post.

2) scalability. Wallpaper of scalability is a persistent problem, the solution is prevention. On the one hand, be sure to set aside the overlapping layer, 0.5mm has some beautiful and one-sided pursuit of this overlap, it is inappropriate. Also, try to buy some scalability good wallpaper.

4 tiles

Tiles, is currently a major renovation project. Specific varieties can refer to other sections of the tiles. Tiles most applied to kitchen, toilet, balcony, and other parts of the wall. Tile decoration of biggest advantage may be resistant to dirt.

Tiles decorated one of the main problems is the waterproofing layer. Because of some cubicles where most useful water problems. So the wall height of waterproofing should take note.

Didn't do waterproof new house or you need to replace the tiles of the old House, you will need to waterproof it again. Waterproof layer of the main approach is to:

Floor and wall height of 1 m used professional waterproofing agent, such as 911, water-repellent. While the walls greater than 1 m of location can use cheaper oil do waterproof asphalt. If the economy does not allow, you can also directly with asphalt or resin do ground waterproof. Ground and ground position of 20 cm must be thick.

New house construction is waterproof, it is necessary to pay attention to check the surface should be no gaps. Old house demolition of old tile surface after briefly do cement Burns before waterproof. Tile construction, if the damage required maintenance, be careful, if thePosition on the low side, it is possible when rupture waterproof in demolition, make up the new brick front, similarly to make waterproof layer may be paving tile repair.

The decoration has been completed, try to avoid in less than 1 m height of drilling and drilling.

As regards the issue of tile joints, check the surface decoration of the chapter.

5. wood finishes

Wood veneer is now to some of the decoration. General is 9% floor with 3% facings, then hit the nail on the mosquito. Wood finishes can be used for a variety of modeling is the main cause of most, and wood panel with various natural texture, you can give the effect of indoor brings gorgeous.

Since the design is different, here you can describe the details, but attention is: wood finishes, like must be descriptive, Chinese painting? quot stay white. The wall planks from the full package of ideas and irrational, apart from increasing the project budget, and on the overall effect is of little help.

No matter what kind of decoration, to keep the surface clean. Decoration Panel after buying approach should brush again as a protective layer of varnish.

Wood finishes, if is decorated Panel decoration, possible technical problems, but if a splint decoration, surface brushed (mixing), then you may have against cracking.

Wood veneer anti-cracking method is:

1) seams to 45 degree angle. Its their contact form the triangle grooved surface.

2) in the slot filled PuTTY PuTTY, and paste sews bandages.

3) surface color matching PuTTY batch Ping. 4) then the rest of the paint layer processing (brush brushing lacquer or mixing).

Wood veneer of fixed with nails must use mosquito nails, in surface processing, you can fill with color matching PuTTY.

6. Stone finishes

The stone of the described in the chapter relating to the materials.

Stone decorative wall, belongs to the high-end decoration. General use of imported marble, the cost is relatively high. Stone (hairy surface stone, culture stone) can be used in the hallway, Hall, hallway, and other public areas.

In the walls decorated with stone construction, mainly divided into two approaches: wet paste method and two dry hanging method.

1. wet paste method and the laying of ceramic tiles are identical, the concrete construction methods see on 2, hanging method is currently in preparation of the construction industry, welcomed the resumption. But as the hanging method needs to take up extra space, so for smaller indoor decoration, is less.

1) prior to the edge of the stone, the size of the Groove notch depends on the specifications of the pendant.

2) first galvanized bulgy screw installation light steel structure. Structure of the installation, to be straight, flat.

3) installation of pendant and install slate, and then in edge joints on glass glue.

The hanging method is only suitable for interior construction, external hanging construction, most are no longer building areas, here in detail.
