Contact Adhesive Problem Solving Guide
If the following occurs | What to look for | Possible solutions |
1. Edge lifting from substrate | a. Insufficient adhesive
coverage
b. insufficient dry time c. not enough pressure when applying |
a. apply more adhesive to veneer
and substrate
b. increase drying time for adhesion c. apply more pressure |
2. Bubbles in the Veneer | a. trapped solvent
b. edges bonded first c. uneven adhesive coverage d. uneven pressure e. ineffective glue |
a. increase dry time
b. apply pressure from center outwards c. review application procedure NOTE: spraying is the best method, rolling is good, brushing is OK. d. review pressure procedure e. use glue with more solids |
3. Adhesive failure on both substrates | a. insufficient pressure
b. insufficient adhesive c. contamination of adhesive surface d. wrong substrate |
a. increase pressure
b. go over surface with an iron at about 200-225 degrees c. keep work area clean NOTE: MDF board is recommended over particle board and particle board is recommended over plywood d. do not apply veneer over substrate with laminate on |
4. Weak or no contact bond | a. exceeded life of contact bond
b. trapped solvent c. adhesive surface has been contaminated by moisture |
a. check to see if glue is old
b. increase drying time c. check spray equipment for moisture in line and increase dry temperature during high humidity |
5. Adhesive releases from one substrate | a. contamination of substrate
surface
b. contact adhesive is not dry |
a. clean substrate thoroughly
b. increase drying time |
