How To Prevent Open End Joints


How to prevent open end joints At Lanco Adhesives we know the challenges you face, and we have the expertise and wide selection of high-performance products to help you succeed – whatever the job requirements or equipment limitations. Open joints at the ends of edge-glued panels are common in cold dry winter months In most cases, they are caused by rapid drying of the panels after gluing. Make sure that the moisture content of the wood is 6-8%, and the relative humidity in the plant is between 30- 40%. Make sure the staves are being prepped/ machined properly before gluing. For ultimate security, Franklin’s Wood-Size concentrate will help seal the end grains and prevent dry air from getting into the glue joints. Your early winter check list should include: • Planer Make sure staves are evenly planed. • Moisture Content of Lumber 6-8% is recommended. • Humidity in Plant May need to introduce humidifiers where lumber is stored and glued. • Secure Clamp Times Ensure enough time in the press. • Wood Size Concentrate Seal end grains to prevent loss of moisture and, ultimately, open end joints.
