A: Dry wood, concrete, drywall, OSB/plywood, and subfloor sheathing. For strongest adhesion and crisp snaps, use in dry weather and on clean surfaces.

Q: How do I minimize staining and speed cleanup?
A: Don’t overfill the reel, keep the cap closed, snap on clean, dry surfaces, and clean soon after use—start with a dry brush, then a damp cloth if needed.
