NELMA’s Eastern White Pine grade rules define the limiting characteristics (knots, holes, splits, etc.) allowed in each grade (quality level). While the rules describe the poorest piece permitted within a grade, it is unlikely the maximum size or number of these characteristics would be present in any board.

Finish Grade

Grade Description

Finish grade material is a fine appearance, knotty grade calling for sound, tight knots that can be finished to take advantage of the natural characteristics of the piece or to give a fine smooth painted surface. The reverse face of Finish shall permit sound characteristics typical of Standard grade material.

This grade allows small, sound and tight knots ranging from 1 1⁄4" red knots and 5⁄8" black knots on a 4" board to 2 1⁄2" red knots and 7⁄8" black knots on a 12" or wider board. Knot holes in the face are not allowed. Checks will be no longer than 4". Pockets are very small and well scattered. Shake is light. A split will not exceed 1⁄2 the width. Pitch, when present, is evident but limited in its impact on the appearance of the piece. Medium stain (blue or coffee) cannot exceed 1⁄2 the face surface area. Wane is limited to the back face on one edge only. Skip (back face or one edge) is limited to 10% of the pieces.
