Wooden furniture is a type of furniture that is very common to us now. For the health and environmental protection needs of our family, many people will choose solid wood furniture when buying furniture. Solid wood furniture is produced during the production process. Many links and steps, one of which is painting.
Painting furniture is a very important part. The quality of the paint directly affects the environmental protection and performance of the furniture. The painting process also directly determines the appearance of the furniture surface. Let's take a look at the steps of painting furniture, that is, the painting process of standard furniture.
If the wooden furniture is painted by classification, there are three different painting methods: closed, semi-closed and open. The final effect of different painting methods is also different. Specifically, after the closed-type painting, the fine lines of the wood can hardly be seen, while the open-type effect is more natural and shows the texture of the wood.
There is not much difference between the various construction methods, the basic construction sequence: white blank board → sanding → substrate closed (scraping putty) → sanding → brushing primer (first pass) → sanding → brushing primer (second ~3 times) → Fully polished → Brushed topcoat (first pass) → Polished → Brushed topcoat (second pass)
Wood furniture coating sequence
01 Sheet processing
Before painting, first clean the wood and wipe off the dust on the surface of the wood. A special dust cloth can be used for cleaning. Large areas such as floors can be vacuumed repeatedly with a vacuum cleaner. At the same time, use sandpaper to polish the surface of the board or the wood line, pay attention to protect the veneer, not sand.
02 sheet closed
Apply the formulated special plate sealing agent to the plate evenly, which can effectively seal the plate and prevent the plate from being contaminated. The sealing of the plate can prevent the plate from absorbing excessive moisture, loosing moisture and deforming the plate, enhance the adhesion between the paint film and the plate, save the amount of paint, and enhance the hardness of the paint film.
03 Scrape Putty
Use the matching wooden putty. After it is prepared, apply the putty to the wooden eye. After the putty is dry, use sandpaper to polish it, and completely clean the putty on the wood. Filling wooden holes with putty can reduce the amount of wood paint and improve the flatness of the paint film. Different paint effects have different requirements for the putty. For example, to achieve an open effect, the color of the putty should be adjusted to match the color of the board before scraping.
04 Primer construction
Adjust the primer of woodware according to the required ratio, which can be applied by brushing or spraying. The role of primer construction is to fill the wood holes and increase the thickness of the paint film. During the construction, pay attention to that after the primer has dried completely, it must be sanded thoroughly with sandpaper before applying the primer again. It is required to be evenly painted, without sagging, and the wood eye is filled smoothly.
05 Sanding treatment
Sanding the board with sandpaper is actually a step that runs through the entire wood paint construction process. Sanding is required for board processing, sanding for putty coating, sanding for primer construction, and sanding before and after topcoat construction. The step of sanding is critical. Sanding treatment makes the board smoother and smoother, which is good for painting. Sanding after painting makes the surface of the paint film smooth and smooth. However, pay attention to avoid horizontal sanding during sanding, and do not use too thick sandpaper for sanding.
06 Topcoat Construction
Before the topcoat construction, the wood surface must be cleaned again to remove dust particles, so that the surface of the paint film can have a better coating effect. Each time you apply topcoat, it is not advisable to apply too thick one time. It is best to take multiple brushing methods and wait for the paint film to dry before proceeding to the next layer of construction. The topcoat construction directly affects the final effect of the paint film. The topcoat construction requires that it be applied evenly, without sagging, good gloss, no obvious brush marks, and smooth and delicate feel.
