What must be paid attention to in rainy season decoration?

The rainy season decoration, whether it is material selection, transportation, preservation or construction, needs attention. Note 1: the plates should be prepared in advance, and the air humidity is high in rainy days. Some materials that are easy to absorb moisture, such as wood, board, gypsum board, etc., are easy to get wet if they are not handled properly during transportation or storage. The board will be mildewed after being affected by moisture, and the wooden keel and finished wood products made of the board will be easily cracked and deformed as the air gradually dries. For example, the gypsum ceiling with plate as keel, because the shrinkage coefficient of plate is larger than gypsum, the deformation of wooden keel will directly lead to the cracking of gypsum ceiling, which will affect the decoration quality. Therefore, the decoration materials, especially the plates that are easy to absorb water, should not be transported in rainy days, but should be prepared in sunny days and put in a closed room for use in rainy days. When buying materials, it is best to go to the supermarket or wholesaler. The wood they buy is generally dry. Note 2: Paints and coatings should be sealed and kept. Whether it is oily paint or water-based paint, if it has been opened for use, it needs to be sealed in rainy days. Theoretically, the unopened coating product itself is very strict in sealing and is not easy to be attacked by moisture. Therefore, experts suggest that if paint products are stored outdoors or on uncovered balconies in a large area, it is best to cover them with plastic sheets or newspapers, otherwise the paint can't be used after it gets wet, which will cause waste. Note 3: prevent the wire from being exposed and deformed. When decorating in rainy days, special attention should be paid to circuit layout, and more attention should be paid to the standardized operation of circuit transformation. Bare wires can't be directly buried in walls or floors, and should be protected by insulated wire tubes. Especially in places that are easy to get wet by rain, such as balconies, when burying wires, it is necessary to wrap the exposed copper wires to prevent the wires from being short-circuited after being wet. Note 4: It is forbidden to paint wood products in rainy days. For wood products, whether painting varnish or nitrocellulose paint when mixing oil, try not to arrange painting in rainy days. Because the surface of wood products will condense a layer of water vapor in rainy days, if paint is painted at this time, water vapor will be wrapped in the paint film, making the surface of wood products turbid. For example, brushing nitrocellulose paint in rainy days will lead to uneven color; It turns white when you draw. According to experts, many process steps in decoration have a "technical intermission time". For example, cement needs a curing period of 24 hours, and every time putty is scraped, it has to go through a drying period, and it can be scraped again after each drying; The paint also needs to be dried thoroughly every time before being brushed for the second and third time. The drying time in rainy season is about twice as long as that in spring and autumn. Therefore, in rainy days, the intermittent time of this technology generally needs to be extended, so we must wait patiently. Note 5: avoid laying wooden floors in rainy days, whether it is laying solid wood floors or composite floors, try to avoid laying in rainy days. Because the air is wet and the ground is wet on rainy days, the water evaporates slowly and the glue dries slowly. In this case, the wooden floor will be easily deformed or hollowed out, especially on the first floor, and there will be moisture regain. On cloudy days when the air humidity is not very high, you can spread the wooden floor, but you should pay attention to remind the decorators to spread it more densely, otherwise the water will be evaporated in sunny days, which will lead to the contraction of the wooden floor and the increase of the gap between the floors.
