Check the production of wooden doors.
Check whether the wooden door is well made and ensure that its water content is in harmony with the local climate.
Grind the surface
Gently polish with sandpaper to remove burrs and other impurities and make the surface smoother.
Apply primer and topcoat.
Apply sealing primer to prepare for subsequent painting. Brush the white primer 2-3 times to make the color fuller. Brush the top coat for 2-3 times, and the effect will be better after the last polishing.
Inspection and maintenance
After drying, check and polish again to ensure that the surface is free of defects. Use putty such as putty for batch scraping and polishing to enhance the smoothness of the surface (if necessary). Grind again and repair the defective parts with putty.
Polished finish
Finally, according to the need, it can also be polished to make the wooden door glow with new brilliance.
