Rainy days how to paint the rainy day Paint brush matters needing attention
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.
In addition, the rainy season construction should prevent the wooden products from being deformed by moisture. The most important thing in the construction of the rainy season is to prevent the deformation of wood products produced on site.
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. If it is necessary to meet the deadline, 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.
Rainy day paint brush Note: Whether it is paving solid wood flooring or composite flooring, try not to carry out the rain on the day. 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. When the wooden doors and windows are formed but not painted (sprayed), the weights can be pressed against the flat for nearly one week, so that the structure of the doors or windows is basically stable, so that the wood products can be prevented 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.
