However, if nitrocellulose paint and polyurethane paint are selected, related curing agents and diluents are needed and must be prepared in strict accordance with a fixed ratio.
Therefore, in the process of construction, it is best to have professional guidance.
Select the matching diluent and curing agent in strict proportion to avoid problems such as undercut and wrinkling.
2. When choosing fine sandpaper to polish the construction, coarse sandpaper should be used instead of coarse sandpaper for quick drawing.
Polishing is more delicate and the adhesion of paint film is better.
3, need to set aside drying time Generally speaking, the primer can be brushed twice, the topcoat can be brushed three times, but it takes 4-6 hours to brush the second time. Workers brush it for the second time every 1-2 hours for quick drawing, and the paint film is not completely dry, which affects the final effect.
4. It is best to remove the wooden door for construction. The renovation of wooden doors is mostly carried out indoors. It's best to remove the door and put it in a special room for spraying.
First, there is no dust, which reduces environmental pollution; Secondly, you can see the front and back of the door very clearly.
If it is directly sprayed on the door, it is easy to produce fog when spraying, which will affect the line of sight and thus affect the spraying effect.
5, the remaining paint is treated differently. After the water-based wood paint is used up, the remaining paint can be stored in a cool place for later use.
Nitrate paint and polyurethane paint can only be used once because of curing agent and diluent, and the rest of the paint can only be disposed of.
At the same time, after the completion of construction, waste paint should be properly disposed of and tools should be cleaned in time.
