Temperature rises, summer decoration, moisture-proof first

On the one hand, the temperature has risen steadily, and many owners have felt the temperature of “in summer”. On the other hand, the temperature difference between morning and evening has increased, and the frequency of showers has increased frequently.

Changes in climate and phenology have also had a significant impact on the home improvement market that has just warmed up. Recently, many owners are asking: "After the summer, the weather is getting hotter and hotter, will it affect the construction period? At this time, the start of the work is the off-season of the market, and you can enjoy the selection of materials, but how to avoid the drying and moisture deformation of the materials? Experts said that as long as the details are checked during the construction process, the quality of the decoration will not be affected.

1, maintain ventilation control humidity

Recently renovated owners, at the beginning of the summer, the outdoor is hot, the interior is still good, in fact, is a good season for decoration. Consumers are worried about the dampness of summer. The biggest difficulty is the humid air after entering the sauna and rainy seasons. Moisture is easy to cause mildew. Therefore, the indoor construction environment should be kept as airy as possible. It is especially important that construction sites such as walls and woodwork that are susceptible to moisture need to be extra cautious.

It is understood that more than half of the experts said that owners who are worried about the quality of summer construction can be assured that now the quality of the plate expansion is completely resistant to high temperature days and climate change, as long as the dry humidity and water content of the material during the construction process. Carrying out good control will not affect the quality of the decoration.

According to reports, if the moisture penetrates into the base layer of the wall, and the base layer is not dried, it will be painted, and the paint will have a white "fog". In severe cases, it may appear as falling and cracking. Generally speaking, after the summer, the drying time of the wall will be longer than other seasons, and it will take at least 5 to 8 days.

It takes 3 to 5 days for the wall to dry naturally. The drying time required for the summer rainy season is about doubled. If the base layer of the wall is not completely dry, the wall paint must not be applied. If cross-construction is allowed on site, the oiler can approach the wall in advance to allow sufficient drying time for the base of the wall.

2, material selection and storage attention to moisture

Large changes in temperature or frequent shower days can also affect the construction of the site. The moisture content of wood is also extremely important during construction in summer. “The normal moisture content should be less than 12%. If the wood is not in moisture, the wood products will be discolored, deformed or even moldy.”

When selecting materials, be sure to buy wood with acceptable moisture content. "When buying materials, you can choose a product that is easier to dry. When the material comes into the field, it will be placed for a day or two, so that it is the same as the surrounding humidity, so it is more suitable to use. It is."

In addition, the board should be protected from strong sunlight; if it is wet during rain, it needs to be protected from moisture and deformation during storage. Do not leave the plates and wood in a room exposed to direct sunlight. The sun exposure will accelerate the aging of the paint on the surface of the wood products.

In summer, the air becomes damp, which will cause the wooden floor to shrink, the gap to increase, the gap between the wall and the door frame to be different, and the wall surface to crack. “These are normal phenomena that occur in seasonal conversions. 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 is adapted to the external climate. ."

3, open at high temperature to release odor

“Any building material will have some pollutants, but in the summer decoration process, the base layer such as wood board is exposed, it can volatilize its pungent taste as soon as possible. After 7 or 8 months of high temperature drying, the impact on the subsequent use will be The smallest. Summer is the season to accelerate the release of harmful substances such as formaldehyde. From another perspective, it is beneficial to test whether home improvement materials and finished furniture are environmentally friendly.

If the consumer opens the door leaf, drawer, and lid of the furniture, the upper respiratory tract has a stimulating feeling, and the eyes shed tears, indicating that the amount of formaldehyde released has exceeded 4 times. Free formaldehyde in wood-based panels should be volatilized for at least 3 to 5 years. Consumers who use odorous furniture and sofas for a long time will affect their health. A children's furniture processing enterprise said that with wood materials as an example, when the temperature reaches 28 ° C or more and the humidity exceeds 45%, formaldehyde will be released in multiples. "Using the nose can roughly judge whether the furniture material is environmentally friendly.
