Do you know what will happen if you paint in rainy days?

There is an owner who wants to paint his house in rainy days in order to catch up with the construction period. In this way, after the paint dries, paint spots with different widths are left on the doors and windows, which undoubtedly makes the joy of the new house mixed with some troubles. A senior painter reminded the owner not to mix oil painting nitrocellulose lacquer or wood varnish painting in rainy days.

Painting in rainy days will have serious consequences.

Wood products will condense a layer of water vapor in rainy days. If you insist on painting at this time, water vapor will soak in it, which will not only make the surface of wood products turbid, but also lead to uneven color. If the owner paints it, it will turn white.

Professional advice

Professionals suggest that if you must catch up with the construction period, you can add a proper amount of whitening powder to the paint. It is understood that chemical white powder can absorb moisture in the air and speed up drying, but it will also have a certain negative impact on the quality of the project. So it is unwise to insist on painting in rainy days.

Moisture-proof deformation of wood products

At the same time, it is worth noting that the most important thing in rainy season construction is to prevent the deformation of wood products made on site. When wooden doors and windows are formed but not painted (sprayed), they can be flattened with heavy objects for nearly a week, so that the structure of doors and windows is basically stable, thus preventing the deformation of wood products due to moisture.
