Rainy weather in summer is very troublesome. Bian Xiao teaches you how to protect your house from moisture.

Since the summer, it rains occasionally. In rainy weather, the moisture content in the air is relatively high. For some decoration materials that are easy to absorb moisture, mildew or deformation will occur after being damp, which will affect the use. In addition, such links as painting, flooring, circuit transformation, etc., also need to be extra cautious in rainy days. So how is the house decoration moisture-proof? In rainy weather, the moisture content in the air is relatively high. For some decoration materials that are easy to absorb moisture, mildew or deformation will occur after being damp, which will affect the use. In addition, such links as painting, flooring, circuit transformation, etc., also need to be extra cautious in rainy days. As long as protective measures are taken in procurement, transportation, storage and construction, the renovation can be completed as scheduled in summer and rainy season. How to prevent moisture in house decoration: prepare wooden materials in advance. On rainy days, the air humidity is high. Some materials that are easy to absorb moisture, such as wood, board, gypsum board, etc., are easily affected by moisture if they are not handled properly during transportation or storage. After being damp, the board will be mildewed. Moreover, after the wooden keel and wooden finished 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. Tip: Decoration materials, especially wood materials that are easy to absorb water, should not be transported in rainy days. They should be prepared in sunny days and put in a closed room for use in rainy days. How to prevent moisture in house decoration: Paints and coatings, whether oily or waterborne, need to be sealed and preserved in rainy days if they have been opened for use. Theoretically, the unopened coating product itself is very strict in sealing and is not easy to be attacked by moisture. Tip: 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 and other items, otherwise the paint can't be used after being damp, resulting in waste. How to prevent moisture in house decoration: whether the floor is the original packaged solid wood floor or solid wood composite floor, it will affect the moisture content in extremely humid rainy days, leading to deformation or cracking. Tip: In order to avoid moisture intrusion, it is suggested that the floor should not be unpacked after being shipped home, but kept in the original packaging to reduce the influence of humidity change. How to protect the house from moisture: it is forbidden to paint wood products. For wood products, whether it is varnishing or nitrocellulose painting when oil is mixed, try not to brush them in rainy days. Because 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, which will make the surface of wood products turbid. Tip: for example, brushing nitrocellulose paint in rainy days will lead to uneven color; It turns white when you draw. How to prevent moisture in house decoration: avoid laying wooden floors, whether it is 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. Tip: 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 densely, otherwise, when the sunshine is sufficient, the water will be evaporated, which will lead to the contraction of the wooden floor and the increase of the gap between the floors. Put an end to bare wires. 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 decoration. 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. Tip: Pay more attention to this point, especially the wires surrounding wet wooden keel, large core board and other wood products. Otherwise, a little carelessness may cause a fire. What should I do if the decoration materials are damp? Cement: Once it rains, it should be used immediately. If the rain evaporates and the cement solidifies into blocks, it is forbidden to use it again. Floor: usually, plastic sheets are attached to the packaging cartons. If the plastic sheet is damaged and the rain directly hits the floor, it cannot be used and needs to be purchased again. Tile: The use of paving will not be affected after being caught in the rain, but it should be noted that the color on the ceramic tile packaging carton may be printed on the surface of the ceramic tile after being caught in the rain. Wood material: If the deformation is not serious after being caught in the rain, it can be placed horizontally, pressed with heavy objects to prevent warping, and can be used after being naturally dried. Tip: extend the drying time of the wall. 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 2 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 will generally be extended, so we must wait patiently. Pay attention to indoor ventilation and sewage discharge. Opening doors and windows can prevent the accumulation of harmful substances. When the humidity is high in rainy days, the release of harmful gases in decoration materials will increase. In order to prevent indoor humidity from increasing, it is often necessary to seal doors and windows, which is more likely to cause a large accumulation of indoor pollutants. In order to avoid being hurt in decoration pollution, in addition to using non-toxic and low-toxic decoration materials as far as possible, please ask a regular home improvement company to carry out construction, but also do a good job in ventilation and air purification of the decoration room, and choose indoor ventilation devices and air purification devices.
