Spraying construction paint film than brush paint film more flat. Spray with water-based wood paint should be added on the basis of the original paint 5% ~ 30% of the tap water dilute after use, for the viscosity of the paint water should also increase, the diluted paint after its coating a 4 cup viscosity should be around 18 ~ 20s. Dilute mix well should be static at least 20 minutes, until the bubbles into the basic disappearance of coating. Before spraying the paint must be more than 200 mesh filter, so as not to bring impurities, affecting the quality of paint film. Water - based paint can be used ordinary spray machine or high - pressure airless spray machine construction. Pay attention to not too fine atomization, but also to prevent bad atomization. The amount of paint should not be too large, not spray too thick, wet film thickness around 50um is good, or easy to produce flow hang, orange peel and other ills. Water-based paint spraying common mistake is a construction too thick, if you want to increase the film thickness, it is appropriate to use multiple spraying method. When spraying on the vertical surface, the spray gun should be slightly at an Angle to the construction surface. Avoid excessive spraying on the vertical surface to avoid sagging. The two paints must be sanded with more than 400# sandpaper. The compressed air is blown off and cleaned with a damp cloth, which increases the adhesion between the two paint films.

3.Process variations of different paint types Applying a matt lacquer to the varnish can change the coating to a matte finish, while applying a varnish to a matt lacquer reduces the brightness of the film and does not achieve maximum brightness and transparency. The color paint of waterborne wood lacquer can be divided into two types: coloured coating and transparent color paint. The coloured coating is made of red, yellow, blue, white and black pigment paste and varnish. It has sufficient hiding power and can be made into matt type. The construction method is the same as varnish. Generally, 2 to 3 passes can achieve satisfactory results. Transparent paint can be done in two ways. One is to use a transparent pigment (or dye) to make a transparent paint and then apply; Another way is to use the base coloring method，First use water - based or oil - based paste to brush wood, then varnished after polishing.After repeated treatments, the coloring and fullness are satisfactory.For open painting, because the micropores on the surface of the wood are to be revealed, the solid color paint with strong hiding power is not easy to use, and the effect can be achieved by coating with a transparent color paint. Of course, the number of paintings is not excessive. Sinograce chemical industry co., LTD.

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.
