When is the best time to decorate, for example, when Guangdong Province returns to Nantian at this time, it is particularly troublesome to paint? Do you have any construction skills?

Because the decoration technology was relatively backward in the past, especially in the rainy season, the decoration had a certain impact on the progress and quality of the project, so there has always been a custom in the south that it is not appropriate to break ground for decoration before Qingming. However, with the improvement of home improvement technology and the refinement of division of labor, the impact of weather on the project has been greatly reduced. "In the process of construction in this weather, the influence of doing hydropower and bricklaying is not great. The key is paint: one is wall paint and the other is wood paint. These two links must not be constructed when it is wet, but only when the weather is good. " Zhao Weihua said that the painting process is greatly affected, which is basically in the final stage of decoration, as long as it can avoid construction in rainy days.

Although the return of the south has a great influence on the decoration, some projects are not affected by the weather, for example, masons are most suitable for operation in wet weather. Because the air is humid, cement concrete dries slowly and can coagulate better. The masonry wall is not easy to have small cracks in the future, flat and durable, but the quality is better. Moreover, this stage is not the peak of decoration, and the labor costs of workers are relatively cheap.

The method of decoration in wet weather is to flexibly adjust the construction process. As long as the process arrangement is reasonable and some adjustments are made during construction, all kinds of unfavorable factors can be avoided. Zhao Weihua suggested that owners who want to decorate in the spring can calculate the time, do bricklayers and arrange water and electricity in front of Tomb-Sweeping Day, and wait until the weather gets warmer after Qingming before scraping putty, painting walls and doing carpentry, which will not delay time and save costs.

Woodworking should take moisture-proof measures.

Wet weather has a great influence on carpentry. The more unfavorable the weather is, the more emphasis should be placed on construction specifications and advanced technology. When doing carpentry in Huannantian, three measures can be taken to effectively prevent moisture: the first is to apply moisture-proof oil to the surface of furniture (the part attached to the wall), the second is to apply moisture-proof oil to the wall (the part attached to the furniture), and the third is to attach a protective film to the finished wood products. When installing, there should be a gap of 1 cm between the furniture and the wall, rather than a complete fit, so that moisture can be discharged. It is understood that this advanced moisture-proof technology can only be achieved by a few decoration companies.

In addition, the back of the furniture should keep a distance of about 5 cm from the wall to prevent the absorption of moisture from the wall. When making the ceiling, you should make the top surface of the wooden keel, and brush the moisture-proof oil first. Brush a layer of white fireproof material after the keel is finished.

The suspended ceiling should be waterproof, moistureproof and fireproof.

Nowadays, the living room area of residential buildings is generally large, so it is not uncommon to see the ceiling of a large space. Ceiling decoration requires higher construction technology, especially for ceilings over 1.5 square meters and ceilings in kitchens and bathrooms, and more attention should be paid to "three defenses", that is, waterproof, moistureproof and fireproof. In the choice of materials, it is not recommended to use wooden keel, and it is best to use light steel keel. 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 the humid weather in Qingyuan in spring. If you want to use wooden keel due to various factors, you must choose materials with low moisture content.

The paint should be changed to spray paint.

For wood products, remember not to paint in rainy days or in the south. The surface of wood products will condense a layer of water in wet weather, which is not easy to dry. At this time, if you paint, water will be wrapped in the paint film, which will make the surface of wood products turbid and cause sagging. In addition, this practice will also lead to uneven color and whitening. Therefore, under normal circumstances, even if construction workers are required to do other work first or stop work for two days, they should try not to do painting work in the south, especially in rainy days.

If we must meet the deadline, we'd better paint with nitrolacquer instead of polyester paint in spring. Because the drying time of nitrocellulose lacquer is fast, while that of polyester paint is relatively long. In addition, a certain amount of white water admixture can be added to the paint to prevent the paint surface from whitening.

It is not suitable to feed in rainy days.

The hidden dangers of repairing weather decoration in Huinan are mainly manifested in the cracking of new walls, arching of plates and deformation of wooden furniture. These are directly related to the expansion of wood. Therefore, the moisture-proof work of decoration materials is particularly important. The most important thing is not to enter the decoration materials in rainy days. Once the wet materials are transported to the construction environment and not fully air-dried, they will be severely cracked and deformed within 3 months after decoration. All kinds of materials should enter the market in an orderly manner, and don't rush to move all the decoration materials into the new house.

The site should protect the finished decoration products.

When decorating in rainy days, we should pay attention to the standardized operation of circuit transformation, especially in places that are easy to get wet by rain, such as balconies, and we must wrap the exposed copper wires to prevent the wires from being short-circuited after being wet. Especially the wires around wooden products such as wet wooden keel and large core board, we should pay more attention to this.

In addition, 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 water sources to prevent the cement from getting wet or forming lumps after soaking. However, the plastered cement will still be affected by air humidity, and the setting speed will slow down. Therefore, after laying floor tiles, protective measures should be taken.

-Question and answer on rainy day decoration

Q: When indoor decoration is carried out in wet weather, the materials that are easily affected are mostly wood, board and gypsum board. , relatively easy to absorb water. What should I do?

Answer: When the air humidity is high, wood, board and gypsum board are easy to get wet. After the water in the material volatilizes, it is easy to crack and deform, and it will also affect other materials and quality. First of all, you must go to the big wholesalers to buy wood, because many of the big wholesalers' wood is dried, and they pick up the goods directly from the container, which reduces the intermediate links and reduces the chance of wood getting wet. When dealing with materials similar to gypsum, the setting time should be strictly controlled, because gypsum molding is not easy to control in wet weather, so the setting time should be strictly controlled to achieve the standard compressive tensile strength and fineness.

Q: A lot of paint will be used in decoration, but is the paint greatly affected by wet weather?

A: In wet weather, paint will slowly dry. If it is not handled properly, it will become moldy and stale, so be careful when handling paint. When dealing with these coatings, it is necessary to predict the humid climate, and pay special attention to the stability, adhesive strength and initial drying crack resistance of the coatings, such as carefully observing the nuances, making detailed time records, and then comparing them. When decorating, latex paint will become moldy due to slow drying in humid weather. After construction, the air conditioner can be turned on to dehumidify, and the moisture in the air can be completely removed, with good effect. Paint also has the problem of slow drying, and it will produce a foggy surface after absorbing moisture in the air. In order to solve this problem, decoration companies generally use blow-drying agents to dry the paint quickly.

Q: Is there anything that needs special attention after the renovation?

A: After the renovation, the weather is humid in spring, and the air convection is relatively small, so there will be problems that various smells cannot be dispersed, which will affect health. It is suggested that more green plants can be placed to remove odor through photosynthesis, or deodorizing things such as lemon, pineapple and grapefruit peel can be placed indoors. As for the reasons for the blackening of the balcony parapet, the main reason is that the external wall is wet in rainy days, and the moisture slowly permeates from the outside of the wall. After the paint of the daughter board is sealed, the water can not be distributed to the outside, resulting in blackening and the paint film is inclined. Therefore, to make a parapet by balcony, we must first deal with the back of the balcony.
