Masters who are accustomed to using oil-based paints are not suitable when they first come into contact with water-based paints, in addition to the completely different characteristics of water-based paints and oil-based paints, and because the wood is too skiny in front of water-based paints! Wood has its temper, and if you want to conquer it with water-based paint, you also need to know about wood.

The personality of wood is faded from the paint. In most people's eyes, it is just an ordinary piece of wood. Have you ever understood its physical structure and chemical composition?

Wood is a natural fiber material. It can be seen from the cross section of the trunk that it is an uneven material composed of different layers, with many textures and small holes in the middle. The trunk is composed of the outer bark, the central pith, and the wooden part between them. The wooden part is the main part of the trunk and the main material for furniture.

The temper of wood is painted with water-based paint, so that we realize the versatility of wood.

Release instinctual wood

Although the amount of gum, resin, pigment, and tannic acid contained in the wood is small, it has a great impact on the film-forming properties and durability of water-based paints. It is necessary to perform necessary treatment before painting, and then select a closed bottom with a suitable function. Paint.

Wood that is "allergic" to water has the characteristics of shrinking, shrinking and shrinking. The process of expansion and contraction can easily cause furniture to deform and crack; therefore, it is necessary to strictly control the moisture content of the wood within the qualified range when applying water-based paint. . At the same time, the method of heating the wood, effectively sealing it, and accelerating the drying of the water-based paint can be adopted to effectively reduce the influence of the water in the water-based paint on the wood.

Wood fiber is easy to be hydrophilic. After the water-based paint is applied, an effective drying method must be adopted to ensure that the water in the water-based paint completely evaporates in an orderly manner, avoiding the whiteness and haze of the late coating film due to the volatility of the water. Will breed mold.

Water-based paint with a high glass transition temperature and a hard coating film will make the paint film lack strain, and will not adapt to the expansion and contraction of wood fibers, which will easily lead to cracking, wrinkling, and peeling of paint. .
