When the temperature rises, the summer decoration should be moistureproof first.

The long summer has arrived. On the one hand, the temperature is rising and many owners feel the "summer" temperature. On the other hand, the temperature difference between morning and evening becomes larger and the number of showers increases.

Changes in climate and phenology have also had a major impact on the newly hot home improvement market. Recently, many owners are asking: "After the long summer, the weather is getting hotter and hotter, will it affect the construction period?" At this time, the construction is considered to be the off-season of the market, and you can enjoy preferential material selection. But when purchasing decoration materials, how to avoid the deformation of materials due to dryness and humidity? " Experts said that as long as the details are checked in the construction process, the decoration quality will not be affected.

1. Keep ventilation and control humidity.

Recently renovated owners, summer has just begun, outdoor heat, indoor good, in fact, is a good season for decoration. Consumers are worried that the biggest difficulty in summer humidity is the humid air entering sauna days and after rainy season, which is easy to cause mildew, so the indoor construction environment should be ventilated as much as possible. More importantly, the construction links that are easy to get wet, such as walls and wood products, need to be extra cautious.

It is understood that more than half of the experts said that owners who are worried about the construction quality in summer can rest assured that the expansion degree of good quality plates can completely resist high temperature and climate change. As long as the dry humidity and water content of materials are well controlled during the construction process, the decoration quality will not be affected.

Reportedly, if moisture permeates into the base part of the wall and the base part is not completely dried, white "fog" will appear on the paint surface, and in severe cases, sagging and cracking may occur. Generally speaking, after summer, the drying time of the wall will be longer than other seasons, and it needs to be increased by at least 5 to 8 days.

It takes 3 to 5 days for the wall to dry normally and naturally, and it takes about twice as long in summer and rainy season. If the foundation of the wall is not completely dry, then the wall paint can't be painted. If cross construction is allowed at the site, the oilman can enter the site in advance to treat the wall and leave enough drying time for the wall foundation.

2. Pay attention to the storage of moisture-proof materials.

Large temperature changes or frequent showers will also affect the wood structure construction on site. The moisture content of wood is also very important in summer construction. "Normal moisture content should be less than 12%. If the wood is not moisture-proof, the wood products will become discolored, deformed and even moldy. "

When selecting materials, you must buy wood with qualified moisture content. "When buying materials, you can choose products that are easier to dry. After the material enters the site, it will be placed for a day or two to make it the same as the surrounding humidity, which is more suitable for use. "

In addition, the plate should avoid being exposed to strong sunlight; When the humidity is high in rainy days, moisture-proof and deformation-proof measures should be taken during storage. Don't put boards and wood in a room with direct sunlight. Exposure will accelerate the aging of paint on the surface of wood products.

When the air becomes humid in summer, it will also lead to problems such as shrinkage of wood floors, increased cracks, and cracks in walls and door frames due to different shrinkage rates. "These are normal phenomena in the seasonal transformation. If it is repaired at this time, the water will continue to volatilize and the wall may still continue to crack. It should be repaired after the wall moisture has adapted to the external climate, and the effect will be better. "

3, high temperature outdoor release odor

"Any building material will have some pollutants, but in the summer decoration process, grassroots such as wooden boards are exposed, which can volatilize its pungent smell as soon as possible. After seven or eight months of high temperature exposure, the impact on subsequent use is minimal. " Summer is the season of accelerating the release of harmful substances such as formaldehyde. From another point of view, it is beneficial to test whether home improvement materials and finished furniture are environmentally friendly.

For example, if consumers open the doors, drawers and box covers of furniture, the upper respiratory tract will feel irritating and the eyes will shed tears, indicating that the formaldehyde emission exceeds the standard by more than 4 times. Free formaldehyde in wood-based panels will volatilize for at least 3~5 years, and consumers' long-term use of furniture and sofas with odor will affect their health. A person from a children's furniture processing enterprise said that taking wood materials as an example, when the temperature reaches above 28℃ and the humidity exceeds 45%, formaldehyde will be released in multiples. "Using the nose can roughly judge whether the furniture materials are environmentally friendly.
