Capacity of being impregnated

&;8226; Sapwood: Medium capacity of being impregnated
&;8226; Heartwood: Low capacity of being impregnated


&;8226; Sawing process: ordinary difficulties arise from hardness and low abrasability
&;8226; Drying process: Medium to high speed. Low risk of deformation and crack formation.
&;8226; Planing process: Difficulties due to hardness, abrasability and risk of repelling on pieces of intertwined fibers. Slow mechanisation is recommended
&;8226; Gluing process: Tannins hamper proper adherence
&;8226; Nailing and screwing process: pre-drilling is recommended due to hardness
&;8226; Finish: no particular problems arise
