Capacity of being impregnated
Sapwood: medium to low capacity of being impregnated.
Heartwood: no capable of being impregnated.
Sawing process: easy, except in those cases of resin's excess.
Drying process: easy and fast. Low risk of deformations and crack formation. Resin exudations.
Planing process: easy. Risk of weakening due to the presence of resin.
