During the rainy season last year, Miss Yang renovated her new home. In order to catch up, the workers proposed to paint on rainy days. Miss Yang did not understand the seriousness of the matter and agreed. As a result, there are wide and narrow paint marks on the doors and windows. Every time I think of this, Miss Yang will have faint pain in her heart. Experts in the industry pointed out that during the rainy season decoration, attention must be paid to maintaining indoor ventilation, not raining on the rain, and not trying to spread wooden floors.
Nippon Paint ( Western Chemicals )
1, to maintain good indoor ventilation. During the rainy days, the air is damp. Open all doors and windows during construction to maintain good indoor ventilation. This will not only benefit the physical health of construction workers, but also help the interior walls, floors and timber to dry as soon as possible.
2, do not paint on rainy days. For wood products, whether it is brush varnish or brush lacquer, remember not to brush on a rainy day. Because the surface of wood products will gather a layer of water vapor in the rainy day, if paint is applied, water vapor will be trapped in the paint film, making the surface of wood products cloudy and unclear. For example, nitrocellulose lacquer on rainy days will lead to uneven color and brushing will cause whitening.
Experts suggest that if a certain period of time is required, a certain amount of white powder may be added to the paint. White powder can absorb the moisture in the air and accelerate the drying speed, but it will also have a negative impact on the quality of the project. So under normal circumstances, even if the construction team has to do something else or suspend work for two days, do not paint as much as possible in the rain.
3, puttying to extend the drying time. The putty is the wall lining material we choose. This material is waterproof, moisture-proof, anti-powder and mildew-proof. To putty in front of the wall, you usually need to scrape 1 to 3 times, during which the normal dry time is 1 to 2 days. However, in the rainy days, putty should be wiped clean with a dry cloth to keep the walls dry as much as possible. At the same time, according to the actual conditions of the weather, the time for putty drying should be extended as much as possible, generally 2 to 3 days is appropriate.
4. The most important thing in the construction of the rainy season is to prevent the deformation of wood products produced on site. Experts suggest that when a wooden door or window is formed but not painted (sprayed), the weight can be pressed against the flat for nearly a week, so that the structure of the door or window is basically stable. This prevents wood products from being deformed due to moisture. . After the veneer material enters the site, firstly, the bottom sealing oil controls the absorption of moisture; the door sleeve and the door closes the opening line, leaving a shrinkage amount when the nail is installed, and then using an edge-sharpening machine to plan flattening after one week, so that shrinkage and cracking can be avoided.
5. Whether it is paving solid wood flooring or composite flooring, do not try to paving on rainy days. Because the ground will be damp on rainy days, especially on the first floor, there will also be wetlands. At this point the water evaporates slowly and the glue dries slowly. If the construction is done under this condition, it will easily deform or empty. However, in cloudy weather where the air humidity is not very high, wooden flooring can still be paved, but be careful to make it more compact. Otherwise, once the sky is clear and the water is evaporated, it will cause the wooden floor to contract, resulting in the floor room. The gap is too large.
