Code of practice for finishing of wood and wood-based materials, Part 1: Operations and workmanship
Quick Reference Values
recommended moisture content10% to 12% (up to 15% max depending on zone)
ambient temperature minimum for painting10°C
knotting coats2 coats of shellac knotting
drying time between paint coats24 hours (typical)
Practical Notes
Always sand parallel to the wood grain to prevent visible cross-grain scratches.
End grains are highly absorbent and require extra sealing to prevent uneven moisture absorption and finish dullness.
Ensure wood moisture content is well controlled before applying finishes to prevent blistering, peeling, or fungal growth.
