Veneer sanding – veneer
When sanding on a belt sander, it is not necessary to remove the paper adhesive tape first. However, using cylindrical grinders or a manual scraper and sandpaper - it is necessary.
Drawing. Time-consuming smoothing of the veneered surface with a scraper knife. We bend the knife in our hands, then manually sand the surface with 80-120 sandpaper.
Drawing. A disc sander is not suitable for smoothing veneered surfaces.
We grind the veneered surfaces basically along the fibers. Cross-grinding or disc grinding leaves scratches from the abrasive grains, which will be even more visible after varnishing. All scratches darken, because the wood fibers will be torn crosswise and the board surface will be rough. The same happens after sanding with too coarse grain. Always sand the oiled surface before painting. But be careful! the veneer is only thick 0,8 mm. Therefore, we cannot allow it to be sanded down. Places with sanded veneer are beyond repair. A grain size abrasive can be used for the first grinding, 60, to the second - with a grain size of 80-100 or 120. Visible edges should be sanded with grain paper 80 to a rounding radius of approx 1 mm.
