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.

The third step in the treatment of water-based paint coated substrates is sealing. The role of the water-based putty is to make the surface of the substrate such as wood not very regular and smooth and minor defects and defects, such as pores, fine cracks, pits, joints and concrete, to reduce the surface roughness and increase the flatness.The requirements for water-based putty are good adhesion and filling, easy sanding, good transparency, and no influence on the coating of the upper layer paint.Water-based putty is mostly one-component. The putty seals the micropores on the surface of the wood to not only increase the fullness of the paint film, but also reduce the bubbles generated during the coating process.This is because the paint liquid will seal the air in the micropores during painting. The slight increase in the ambient temperature during the drying process causes the bubbles to expand, which causes the paint surface to form obvious bubbles. This phenomenon is in the waterborne wood paint application. It is very common.Putty is suitable for thick film coating and paint application. For open painting, that is, the effect of painting wood grain and micropores is required, the putty backing shall not be used. Stir the putty before use.The putty can be applied by brushing or scraping, and the brushing method can be used to adapt to various shapes of the surface. Depending on the surface roughness of the wood, you can brush 1 to 3 putty.The surface of the uneven surface can also be multi-brushed. Under normal circumstances, it can be brushed two times, each interval is at least 0.5h (the second one is dried after the previous one). Do not use excessive force on sanding. Simply polish it to the unevenness and apply a putty.After the putty is finished, put it for at least 2 hours, smooth it with sandpaper (a little better sanding when it is aired), it is best to use 1000# sandpaper water mill to smooth it.However, in the case where water may cause warping, deformation, or opening of wood, water grinding shall not be performed. Rinse the water after grinding, dry it, and dry it before proceeding to the next step.Most water-based putty has a low solid content and is difficult to fill large gaps and pits on wood. It should be treated with high solids putty or oily putty. Generally, water-based paint can also be used for the coating of wood treated with oily putty. It should be noted that the oily putty must be fully dried. If the water-based paint is not fully dried before it is applied, bubbles will be generated and the film may be attached. bad. For doubtful oily putty, it must be tested first, and no problem can be applied to large-scale construction. Sinograce chemical industry co., LTD.
