Home decoration needs to be cautious, the rainy season is coming to be moisture-proof

Since the summer, there have been occasional rains. In the rainy weather, the moisture content in the air is relatively high. For some decoration materials that are easy to absorb moisture, it will be mildewed or deformed after damp, which will affect the use. In addition, such as painting, paving the floor, circuit transformation, etc., also need to be extra cautious on rainy days. As long as the protection measures are ensured in the aspects of purchase, transportation, storage and construction, the summer rainy season can be safely renovated and completed on schedule.

Humidity change

Wood materials are prepared in advance

On a rainy day, the air humidity is high. Some materials that absorb moisture, such as wood, board, and gypsum board, are improperly handled during transportation or storage, and are highly susceptible to moisture. The board after damp will be mildewed. Moreover, after the wooden keel and the wooden finished product are made of the plate, as the air gradually dries, the moisture in the material volatilizes, and the deformation is easily broken, which may affect other materials. For example, the gypsum ceiling of the keel is made of sheet metal. Because the shrinkage coefficient of the plate is larger than that of the gypsum, the deformation of the wooden keel directly causes the crack of the gypsum ceiling to affect the quality of the decoration.

Tip: The decoration materials are especially wood materials that are easy to absorb water. Don't transport them in rainy weather. When the weather is fine, keep them in a closed room for use in rainy days.

paint

Whether it is oily paint or water-based paint, if it is already opened, it needs to be tightly sealed and sealed in rainy days. In theory, the seal of the paint product without opening the package itself is very strict and is not easily attacked by moisture.

Tip: Experts suggest that if you store paint products on a large outdoor or unobstructed balcony, it is best to cover them with plastic cloth, etc., otherwise the paint will not be used after damp, resulting in waste.

The floor is stored in the original packaging

Whether it is solid wood flooring or parquet, the moisture content is affected during extremely humid rainy days, causing deformation or cracking.

Tip: To avoid moisture intrusion, it is recommended that the floor should not be unpacked after it is delivered to the home, but stored in the original packaging to reduce the effects of humidity changes.

Resolutely banned

Prohibit woodwork painting

For wood products, whether it is brush varnish or nitrocellulose lacquer when mixing oil, try not to arrange it when it is raining. Because the surface of wood products will condense a layer of water vapor on rainy days. If the paint is painted at this time, the water vapor will be wrapped in the paint film, making the surface of the wood product turbid.

Tip: For example, brushing nitrocellulose paint in rainy days will result in uneven color; while painting, there will be whitening.

Avoid laying wooden floors

Whether it is paving solid wood flooring or laminate flooring, try not to lay it on rainy days. Because the air is wet in the rainy days, the ground is damp, the water evaporates slowly, and the glue dries slowly. In this case, the wooden floor is paved, and it will be prone to deformation or hollowing in the future, especially on the first floor.

Tip: In the cloudy days where the air humidity is not very large, it is possible to lay the wooden floor, but it should be noted that the decoration staff should be paved more compactly. Otherwise, the weather will be clear, and the water will be evaporated, which will cause the wooden floor to shrink. The gap increases.

Eliminate wire bare modification

When decorating in rainy days, the circuit layout should pay special attention to it, and more attention should be paid to the standardized operation of circuit modification. The bare wire cannot be buried directly on the wall or the floor, and a protected insulated wire tube should be added. Especially in places such as balconies that are easily exposed to rain, be sure to wrap the copper ends that are exposed to the wires when they are buried to prevent short circuits after the wires are wet.

Tip: Especially for wires around wooden items such as damp wood keels and large core boards, this should be noted. Otherwise, if you are not careful, it is likely to cause a fire.

first-aid

What should I do with the decoration materials?

Cement: Once exposed to rain, it should be used immediately. If the cement is solidified into pieces after the rainwater evaporates, it is forbidden to be reused.

Floor: Usually wrapped in plastic wrap in the carton. If the plastic sheet is damaged and the rain is drenched directly on the floor, it cannot be used for re-purchase.

Tile: It will not affect the paving after being rained. However, it should be noted that after the tile packaging carton is rained, the color on the carton may be printed on the tile surface.

Wood material: After encountering rain, if there is no serious deformation, you can place it horizontally, press the heavy object to prevent lifting, and use it after it is naturally dried.

Tips

Extend wall drying time

Although the effect of rainy days on the wall paint latex paint is not too large, but also pay attention to properly extend the drying time of the wall after the first pass. Generally speaking, the normal interval is about 2 hours, and the rainy days can be extended according to the weather conditions.

According to relevant experts, many process steps in the decoration have a “technical intermittent time”. For example, the cement needs a 24-hour solidification period. Each time the putty is put through a drying period, it can be scraped again after each drying; the paint also needs Brush it again every second and third. Therefore, on a rainy day, this technology intermittent time is generally extended, and you must wait patiently.

Pay attention to indoor ventilation and sewage

Open the door and open the window to prevent the accumulation of harmful substances. Humidity in rainy days will increase the amount of harmful gases released from the decoration materials. In order to prevent the indoor humidity from increasing, it is often necessary to close the doors and windows, which is more likely to cause a large accumulation of indoor pollutants.

In order to avoid damage in the decoration pollution, in addition to the use of non-toxic and less toxic decorative materials, please formal formal home improvement company construction, but also to do the ventilation and air purification of the renovation room, you can also choose indoor ventilation and air purification Device.
