'A' Grade Plywood Sanding
|
What grit is 'A' grade plywood sanded to from the factory?
T. C. Knight: The APA Engineered Wood Association specifies a Grade A face to be "fully sanded with 80-grit or better," so it is really up to the manufacturer how much "better" than 80-grit they will sand an A-grade veneer. For instance, Formwood Industries in Indiana claims to sand their panels with 100-grit followed by 150-grit. If you really need to know what grit is used, you will have to contact the specific manufacturer.
