1.The tool

Before using the soft brush, thoroughly soak it in clean water, remove excess water, and do not drip. The enamel paint should only reach half the length of the bristles.Brush as fast as possible, gently and smoothly brush the wood grain, do not apply it back and forth repeatedly, because the water-based paint is fast drying and the opening time is short, so it should be completed as soon as possible.

2.Process

Generally, a water-based primer is applied before the coating of water-based putty to improve the infiltration of wood and increase adhesion. In addition, multiple primers can be used to increase the thickness and fullness of paint film on the putty after grinding.For occasions where the requirements are not high, the primer can also be used as a topcoat, the so-called bottom-type water-based wood lacquer. The primary role of the first primer is the back cover. When painting, the paint liquid should be thin. It can be added with 5%~30% water and diluted to make the paint liquid easily penetrate into the pores of the wood, which is beneficial to increase the adhesion of the paint film.After the first paint is dried (depending on temperature and humidity, it takes about 2~8h), use 400#~600# sandpaper to remove the burrs from the surface of the wood, so that the surface is basically smooth and ready to be putty.After the surface of the putty is sealed, the surface of the wood can be re-primed after being polished and cleaned. After 2 hours, it can be lightly ground and then coated. If it is to be ground, the time should be longer (more than 4 hours). Repeat this process, re-grind and re-coat until you are satisfied. Generally, the primer is applied 2 to 5 times. The more the coating is applied, the better the fullness.

After the multi-primer finish is applied, if the surface condition and fullness of the paint film are basically satisfactory, the coating can be finished. However, when there is a higher requirement for the coating effect, the varnish or the matt lacquer having a certain degree of glaze may be applied 1 to 4 times on the basis of the primer, usually not less than 2 times.The primer should be dried for at least one day before applying the topcoat. Before applying each finish, it is necessary to polish the previous finish with 800# sandpaper to increase the adhesion between the coatings. This is especially important for waterborne polyurethane topcoats. As the last top coat, it is best to add 5% to 10% of water to dilute the original paint before use.

Various topcoats not only have great differences in gloss, but also have great differences in feel, hardness and solvent resistance, especially for more intuitive handfeel performance. Personal preferences are different and can be used with hobbies.
