Final answer:
The veneer-quality marking is based on veneer appearance and ranges from A to D, with A as the highest quality. Water-resistant adhesive pertains to the panel's usage and does not affect the veneer quality grade.
Step-by-step explanation:
The veneer-quality marking for a panel made with water-resistant adhesive would be dependent on the quality of the veneer rather than the type of adhesive used. There are typically four grades of veneer quality ranging from A to D, with A being the highest quality and D being the lowest
These grades reflect the appearance and quality of the veneer surface including the number of knots, splits, and other imperfections. However, water resistance is a characteristic of the adhesive, not the veneer grade. When a panel is made with water-resistant adhesive, it's often intended for exterior use or in high moisture areas, but the grade of the veneer itself would still be marked based on its appearance and quality; A, B, C, or D.
