![]() Finishing: be careful when you select timber for finishing and when you prepare surfaces for paint and varnish due to the high resin content of some material and earlywood/latewood ridging of dressed timber.Gluing: glue can absorb differently between earlywood and latewood, but this rarely causes problems.Fixing: nails tend to follow the growth rings due to deflection by latewood bands be careful when using standard fastening and fittings use a nailing gun for good results.Machining: keep planer blades sharp when dressing to avoid compressing the softer earlywood and causing ridged surfaces. ![]() Hardness: firm (rated 4 on a 6-class scale) to indent and work with hand tools.Seasoning: to avoid distortion, dry framing sizes at high temperatures boards may be air-dried or kiln-dried at conventional or high temperatures.Preservation: immature plantation-grown stems are almost entirely sapwood, which typically comprises more than 50% of the stem radius even in mature plantations sapwood readily impregnates with commercial preservative but the heartwood can’t be adequately treated using available commercial processes. ![]()
