Does it matter to lay the floor in rainy days?

If the rainy day decoration does not take corresponding protective measures, it will have a certain impact on the quality of home improvement. But as long as the moistureproof work is done well, it can still be constructed normally. However, it is best to avoid rainy days for several projects.

Buy materials. In rainy days, the air humidity is high, and some materials that are easy to absorb moisture, such as wood, board, gypsum board, etc., are easy to get wet when they are not handled properly during transportation or storage, and mildew spots will appear on the board after being wet. After wooden keel and wood products are made into plates, with the gradual drying of air, the water in the materials is easy to crack and deform after volatilization, which will also affect other materials. 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. Paint. A layer of water vapor will condense on the surface of wood products in rainy days. If you paint 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. In addition, although rainy days have little effect on wall painting, we should also pay attention to extending the drying time of the wall after the first painting. Generally speaking, the normal interval is about two hours, and the rainy days can be appropriately extended according to the weather conditions. According to experts, many process steps in decoration have a "technical intermission time". For example, cement needs a 24-hour solidification period, 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. Therefore, in rainy days, the intermittent time of this technology generally needs to be extended, so we must wait patiently.

Spread the wooden floor. Whether laying solid wood floors or composite floors, try not to lay them 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 lay wooden floors, but it is very important to check the moisture content of the floors. Generally, laminate flooring and solid wood flooring can meet the requirements, while solid wood flooring and bamboo flooring must be inspected. Otherwise, the indoor air is dry and heated in winter, and the floor will have too big a gap. After passing the inspection, the floor must be put into the original packaging and wrapped with plastic sheets, otherwise the floor will absorb the moisture in the indoor air and be deformed. When paving the wooden floor on cloudy days, the owner should pay attention to remind the decorator to pave it densely, otherwise, on sunny days, the water will evaporate, leading to the contraction of the wooden floor and the increase of the gap between the floors.

Circuit modification. 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. Especially the wires around wooden products such as wet wooden keel and large core board, we should pay more attention to this. Otherwise, a little carelessness may cause a fire.
