Results of observations made to this stage showed that the effect of finishing on wood dimensional stability varied according to wood species, grain orientation and type offinish coat. Finishing had a greater dimensional stabilizing effect on jabon than mangium. Reduction of swelling due to finishing was greater in tangential compared to radial boards.
