## FAQ

### What does the B/BB grade indicate?

The face side (B) has minimal defects, making it suitable for clear finishes. The back side (BB) allows for small veneer patches that do not affect structural integrity.

### Is FSF plywood suitable for damp environments?

Yes, the phenol-formaldehyde adhesive provides increased moisture resistance. The panels maintain their shape and do not delaminate in humid conditions.

### How should I store these plywood sheets?

Store the sheets flat on a level surface in a dry environment. This prevents warping and ensures the panels remain perfectly straight.

### What is the best way to cut 21 mm plywood?

Use a circular saw with a fine-toothed carbide blade. To prevent splintering on the B-grade face, cut slowly and support the sheet properly.

### Where should this plywood not be used?

Due to the phenol-formaldehyde glue, FSF plywood is not recommended for interior wall paneling in bedrooms. It is designed for exterior, structural, or technical use.
