Corner Weld Glue
Definition
Corner Weld Glue is a brand of co-polymer wood glue commonly used in picture framing to securely bond mitered frame corners. It is designed to penetrate wood fibers for strong adhesion, creating a durable join that supports the structural integrity of the frame.
Context
In custom framing, adhesives like Corner Weld Glue are used alongside mechanical fasteners such as V-Nails or dovetail keys to strengthen joints. While nails and fasteners provide immediate hold, wood glues like Corner Weld help maintain long-term stability by preventing joint separation. This glue is particularly valued for its fast-setting qualities and clear finish once dry.
Applications
- Joining mitered corners of picture frames.
- Reinforcing structural integrity of wooden frame mouldings.
- Used in combination with mechanical joinery tools such as underpinners.
- Occasionally applied in other woodworking tasks where clear-drying adhesive is preferred.
Considerations
Although Corner Weld Glue creates a strong bond, it is not reversible and therefore not recommended for conservation framing projects. Conservators typically prefer wheat paste or other reversible adhesives for museum-quality work. Framers should also avoid over-application, as excess glue can seep out of corners and require sanding or cleaning.
