4 filler : silk pigment added wood filler to fill the pipe and increase wood texture sharpness , while achieving filled with colored two functions. Care must be taken when filling adhesion, if the adhesion is poor , then the coating film is easily peeled off ; poor if the coloring , the color is uneven, the wood grain is not clear ; do if filling primer , primer can be saved and paint spraying times , the mirror coating better.

5 first times Primer: Solids usually between 4-14 %, due to low viscosity so quickly penetrate the surface layer of wood, provide coating process "continuation" of the effect .

6 breathing : a dye or pigment added formulated primer over the head , between 2-10 % solids , usually after coloring material or fill operation is completed , in order to deepen the color and use , and its role and head over the primer the same, but can also be directly used to replace solid plastic material coloring and paint two processes on the material, because it does not penetrate the wood coloring agent , it can easily scratch and white marks , pay special attention to vomit satisfied .
