Troubleshooting Assembly Gluing

The following information is a summary of potential issues and recommendations. Check out our complete Assembly Gluing Guide for additional recommendations!

Issue: Weak joint
Possible Causes:

• ‍Loose part fit | Recommendation: Part should fit snugly but not require undue assembly force
• ‍Joint design (dowels too short, etc.) | Recommendation: Redesign joint
• ‍Glue setting too quickly/too slowly | Recommendation: Please contact technical support
• ‍Insufficient glue coverage | Recommendation: Apply uniform coating of glue to all parts of joint
• ‍Burnished surfaces | Recommendation: Sharpen cutter blades
• ‍Overspray of finish on gluing surface | Recommendation: Remove finish before gluing
• ‍Undercured or frosted glue lines due to low temperature | Recommendation: Raise plant, wood, and adhesive temperature
• ‍Undercured or frosted glue lines due to short clamp time| Recommendation: Increase clamp time
• ‍High Moisture Content | Recommendation: 6-8% moisture content recommended
