Plywood veneer grades
Sanded plywood grades are named by the face and back veneer, such as AC or AB. In descending quality: A, B, C-Plugged, C and D. Exterior panels use a fully waterproof bond for permanent weather exposure; Exposure 1 panels use the same adhesive but are meant for construction delays, not permanent exposure.
A
Smooth and paintable. Up to 18 neatly made repairs parallel to grain. Can take a natural finish in less demanding uses.
B
Solid surface. Shims, sled or router repairs and tight knots to 1" across the grain permitted.
C-Plugged
Improved C veneer: splits to 1/8" and knot holes to 1/4 x 1/2". Synthetic repairs permitted.
C
Tight knots to 1-1/2" and knot holes to 1" across grain, with limited splits. Lowest grade for exterior panels.
D
Knots and knot holes to 2-1/2" across grain. Limited to Interior and Exposure 1 panels.
Panel guide
