Decoration class: What are the precautions for returning to Nantian for decoration?

Hello, the most important thing in the decoration of second-hand houses in spring is the process arrangement! We know that the humid air in South China is closely related to the construction quality, and different projects have different requirements for construction humidity.

The main processes of spring decoration include hydropower transformation, tile construction, woodworking construction and painting construction. Under normal weather conditions, the construction sequence is generally water and electricity first, then mud tile and carpentry are carried out at the same time, and finally paint construction is carried out.

The influence of wet weather on the main home improvement process;

1, hydropower transformation: advantages and disadvantages

Although returning to Nantian has no effect on water pipe laying, it has certain hidden dangers on circuit laying. Returning to Nantian may cause water vapor in the threading pipe, which will affect the quality of the conductor. However, due to the protective layer and insulating layer on the surface of the wire, the impact will not be great.

2. Mud tile construction: favorable

Compared with other technologies, wet weather is the most favorable for mud tile construction, because the air is wet, cement concrete dries slowly, and it can coagulate better, and cracks are not easy to appear in the wall in the future. In addition, returning to Nantian is also beneficial to tile laying, and tile laying in Nantian can achieve both flat and beautiful effects.

3. Woodworking construction: there are shortcomings.

Wet weather has a great influence on woodworking construction. Due to the "wet expansion and dry contraction" characteristics of the board, the board is easy to expand due to moisture. When the air humidity returns to normal, the board may shrink, resulting in cracks or deformation. In addition, the water vapor in wet days can easily lead to moldy plates and affect the beauty of wood products.

4. Paint construction: there are shortcomings.

Paint construction includes wood paint construction and wall paint construction. Wet weather has an influence on the drying process of wood paint construction. If the dryness is not good, it is easy to lead to insufficient tightness between the bottom layer and the surface layer, and it is easy to produce bubbles. For the construction of wall paint, in wet days, the paint will slowly dry, and it is easy to be moldy and smelly.

Second, the scientific and reasonable arrangement of construction process

The adverse effects of humid weather on home improvement mainly lie in carpentry construction and painting construction, while the beneficial effects lie in tile construction. Therefore, returning to Nantian does not need to avoid all decoration processes, but only needs to arrange the processes reasonably. Therefore, it is suggested that mud tiles and hydropower renovation projects should be done first in wet weather, and then carpentry and painting should be done after the weather gets warmer. This will not delay time, but also benefit and avoid disadvantages.

(A) back to Nantian to see the skills of tile construction and hydropower transformation.

Although the climate in South China Station is humid, which is beneficial to the construction of mud tiles and has little impact on hydropower transformation, the adverse impact still exists. Let's take a look at the construction skills of mud tiles and hydropower transformation in rainy days.

1, mud tile construction skills

(1) Construction skill of mud tile: the mortar should be well mixed and dried. Cement mortar is an indispensable auxiliary material in mud tile construction. Because the weather is wet, mixing mortar at this time can be made drier than at other times.

(2) Buy ceramic tiles with low water absorption: Pay attention to the difference between ceramics and porcelain when buying ceramic tiles. Porcelain bricks have small water absorption, fine structure and crisp and pleasant knocking sound; However, it is a ceramic tile with high water absorption, many structural holes and dull knocking sound. Ceramic tiles with low water absorption are not easy to crack when the temperature difference between day and night changes in spring.

(3) Maintenance of finished products: When laying floor tiles in rainy days, it is best to cover the cement surface with kraft paper or plastic sheets, and try to stay away from the water source to prevent the cement from getting wet or caking after soaking. Due to the influence of air humidity, the setting speed of plastering cement slows down. Therefore, after laying floor tiles, protective measures should be taken.

2, hydropower transformation construction skills

(1) Dry the electric wire before passing through the pipe: pay attention to prevent moisture from invading when arranging water and electricity in wet weather. During threading construction, it is necessary to ensure that the wires are dry and avoid the potential safety hazard of short circuit caused by water vapor condensation in the pipes.

(2) Protection of the bare conductor: For the protection of the bare conductor, the bare copper core can be wrapped with a special protective cap to prevent it from short-circuiting after being wetted. If necessary, extend the exposed wire length, and then cut it when connecting the wires to ensure that the used part will not be eroded.

(2) Facing the woodworking construction in South China, avoid the influence of humidity.

Woodworking construction is best carried out after the weather gets warmer. However, if it is impossible to avoid carpentry in rainy days because of the construction period or rushing to move in, we can start with the following points in construction to avoid adverse effects as much as possible.

1, procurement and storage of woodworking materials

(1) Wood procurement: When purchasing wood, it is best to go to a big wholesaler, because most of the wood of the big wholesaler is dry, and the goods are directly taken from the container, which reduces intermediate links and reduces the chance of wood getting wet.

(2) Timber entering the site: It is best to choose a sunny and dry time when entering the site, and never enter the timber in rainy days. If wet wood is not fully air-dried once it is transported to the construction environment, it may crack and deform within 3 months after decoration. After the plate comes into play, a layer of sealing paint should be painted immediately to reduce the absorption of water by the pores of the plate.

(3) Wood preservation: Pay attention to the stacking of wood in wet weather, and the board will become soft after absorbing water. In addition, when stacking plates, pay attention to laying them flat. If stacked against the wall, the plates are prone to bending due to pressure.

2, woodworking construction moistureproof skills

(1) Brushing moistureproof oil: When going back to Nantian for woodworking construction, it is necessary to emphasize the construction specifications and use advanced technology. At present, a more effective process is to coat moisture-proof oil on wood products, especially on the parts attached to the wall. In addition, a moisture-proof protective film can be pasted on the surface of furniture.

(2) Try to use light steel keel for ceiling: When making ceiling in spring, it is best to use light steel keel instead of wooden keel in material selection. Light steel keel is firm and not easy to deform, and it is convenient to install and operate. After moisture-proof treatment, it is enough to cope with wet weather. If the wooden keel must be used for special reasons, it is recommended to choose materials with low moisture content and do a good job of moisture prevention.

(3) There should be a gap between the furniture and the wall: when placing furniture, it is best not to stick it on the wall, but generally to stay away from the wall 1cm. This is done to prevent the furniture from being stained by the damp water vapor on the wall. In addition, remember to leave ventilation gaps to avoid mildew between furniture and walls.

(3) Paint construction in South China to avoid the influence of humidity.

Returning to Nantian is not only humid, but also low temperature, which will affect the drying speed of paint film. At this time, various measures can be taken to prevent the slow drying speed from affecting the construction quality.

1, moistureproof skills of wood paint coating

(1) Selection of paint materials: In general, even if construction workers are required to do other processes first or stop work for two days, they should try not to do paint work in the south, especially in rainy days. If wood must be painted, it is recommended to choose nitrocellulose lacquer instead of polyester paint, because the drying time of nitrocellulose lacquer is faster than that of polyester paint.

(2) Spraying method: There are many methods to brush wood paint, including brushing method, rubbing method and spray gun method. It is best to use the spray gun method in rainy days in spring. The other two methods are inefficient and not suitable for quick-drying coatings, while the spray gun method has high efficiency, fast spraying speed and faster drying speed of paint film.

(3) Adding drier: There is still a problem in applying wood paint in rainy days. After the paint absorbs the moisture in the air, it will produce a layer of fog, which will affect the beauty of the paint film. Faced with this problem, drier is usually used to make paint dry faster. In addition, the coating area of wood paint is not particularly large, and the sun lamp can also be used to accelerate the drying of the paint film.

2, wall coating moistureproof skills

(1) Selection of wall topcoat: When brushing the wall topcoat is used in wet weather, the first thing to choose is the paint with better quality. Pay special attention to the stability, adhesive strength and initial drying crack resistance of coatings when purchasing. This can prevent latex paint from becoming moldy because it dries slowly during decoration.

(2) Dehumidification with dehumidifier: In case of moldy latex paint during decoration, dehumidifier can be used for dehumidification after construction to reduce the humidity in indoor air. At the same time, we should pay attention to close the doors and windows in the morning and evening to minimize the entry of humid gas into the room.
