FJ pine (finger-jointed pine)
FJ pine (finger-jointed pine): short pine lengths joined with finger joints, the trade standard for skirting, architrave, and mouldings in Australian construction.
Ask Chalkline about this →FJ pine (finger-jointed pine) is a timber product made by joining short lengths of pine end-to-end with interlocking “finger” shaped glued joints, producing a board or moulding length that is as strong and dimensionally stable as clear-length timber but uses smaller off-cuts. The joints are typically invisible once primed and painted.
In Australian residential construction, FJ pine is the standard material for skirting boards, architraves, door linings, and other internal mouldings. It is more resistant to moisture and warping than standard MDF and is the trade preference for wet areas, laundries, and high-humidity climates. Most suppliers offer it unprimed (ready to sand and prime on-site) or factory-primed (quicker installation, no on-site priming needed before topcoat).
Also known as: finger-jointed pine, FJP, finger-joint pine.
