Weld-Bond Glue

Weld-Bond Glue

Definition

Weld-Bond Glue is a co-polymer or cross-polymer adhesive known for its strong bonding capabilities, particularly effective for joining wood components in picture frame construction. It offers excellent adhesion, flexibility, and durability, making it a preferred glue for assembling mitered corners before mechanical reinforcement.

Uses in Picture Framing

• Applied to mitered corners prior to clamping or inserting fasteners such as V-nails or biscuits.
• Creates a rigid yet slightly flexible bond that withstands environmental changes without cracking.
• Can adhere to wood, MDF, paper, foam, and some plastics, making it versatile for mixed-material frames.

Advantages

• Strong Initial Tack - holds joints together quickly for faster assembly.
• Dries Clear - ideal for visible joints or light-colored mouldings.
• Water-Resistant - suitable for frames exposed to moderate humidity.

Application Tips

• Apply a thin, even layer to both surfaces for maximum bond strength.
• Use clamps or an underpinner to maintain consistent pressure while curing.
• Wipe away excess glue immediately with a damp cloth to avoid staining the finish.
