Description
The grains on the wood surface are destroyed during sanding. The grains on the surface are filled with dilute thermoplastic aqueous varnishes by a process called sizing. Destroyed grains swell and jut themselves out of the surface during sizing. Sanding is performed after flash-off of sizing varnish; a second sanding should be performed to remove these protruded grains. Consequently, wood surface becomes ready for paint application.
