What if it rains during the renovation? Matters needing attention in rainy day decoration

If the rainy weather is frequent during the renovation (especially in the southern region, the humidity is relatively high), the extension of the construction period is inevitable. Owners should keep a peaceful mind and not be impatient. But if decoration is really needed at this time, corresponding protective measures should be taken to minimize the impact. What should I do if it rains during the renovation? Next, I will bring you some precautions in rainy days, hoping to help you.

Matters needing attention in rainy day decoration:

1. Try to avoid purchasing materials in rainy days.

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 improperly handled during transportation or storage, and mildew spots will appear on the board after being wet; Moreover, 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. 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. Therefore, when buying materials, we must pay attention to whether the materials are dry and try to avoid buying them in rainy days.

2, to prevent the deformation of wood products due to moisture.

The most important thing in rainy day decoration is to prevent the deformation of wood products made on site. The specific protection measures are: when the wooden doors and windows are not painted (sprayed), they can be flattened for nearly a week with heavy objects, so that the structure of the doors and windows is basically stable, which can prevent the wood products from being deformed due to moisture. After the veneer materials enter the site, the water absorption should be controlled by the back sealing oil. When nailing, the door cover and the closing line of the door should be set aside for contraction, and then planed with an edge-closing machine one week later to avoid smooth cracking after contraction.

3, blow be bored with child to extend its drying time.

Many process steps in decoration have a "technical intermission time", for example, cement needs a 24-hour solidification period; Every time you scrape putty, you have to go through a drying period, and then scrape it again after each drying. The paint also needs to be dried thoroughly every time before being brushed for the second and third time.

When decorating and scraping putty in rainy days, the wall materials we choose have waterproof, moistureproof, powdering-proof and mildew-proof functions. Putty scraping before wall painting generally takes 1-3 times, during which the normal drying time is 1-2 days. But when scraping putty in rainy days, use a dry cloth to wipe off the moisture on the wall and try to keep the wall dry. At the same time, according to the actual situation of the weather, it is advisable to extend the drying time of putty as much as possible, generally 2-3 days. Therefore, in rainy days, the intermittent time of this technology will generally be extended, so we must wait patiently.

Never draw in rainy days.

For wood products, whether it is varnishing or applying nitrolacquer when mixing oil, remember not to brush in rainy days. Because a layer of water vapor will condense on the surface of wood products in rainy days. At this time, if you paint, water vapor will be wrapped in the paint film, which will make the surface of wood products turbid. For example, painting nitrocellulose paint in rainy days will lead to uneven color, while painting will turn white.

If you must meet the deadline, you can add a certain amount of white powder to the paint. White powder can absorb the moisture in the air and accelerate the drying speed, but it will also bring some negative effects to the engineering quality. Therefore, under normal circumstances, even if the construction team is required to do some other work first or temporarily stop work for two days, try not to do painting work in rainy days. In addition, rainy days have little effect on wall painting, but 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.

5, tile cement can not be affected with damp.

When laying bricks on the ground in rainy days, it is best to cover the cement surface with kraft paper or plastic cloth, and at the same time, try to stay away from the water source to prevent it from being damp or forming blocks after soaking. However, the plastered cement will still be affected by air humidity, which will slow down the setting speed. Therefore, after the floor tiles are laid, don't step on them immediately, but set a springboard to facilitate the passage.

6. Try not to spread the wooden floor when it rains.

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 composite flooring can meet the requirements, while solid wood and bamboo flooring must be inspected, otherwise in winter, indoor drying and heating will lead to the phenomenon that the floor is too large. 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 laying the wooden floor on cloudy days, the owner should pay attention to remind the decorator to lay it tightly, otherwise, on sunny days, the water will evaporate, which will lead to the contraction of the wooden floor and the increase of the gap between the floors.

7. Be careful when the circuit is switched.

When decorating in rainy days, we should pay special attention to the circuit layout, especially 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.

Bian Xiao concluded: Continuous rainy days will definitely delay the renovation period. At this time, we must pay attention not to urge workers to speed up the renovation progress in order to catch up with the construction period in rainy days. Proper shutdown is also necessary. After all, the quality of decoration is the most critical. Speeding up progress in rainy days is often at the expense of project quality.
