1Face veneer bonds well. Lightly sand to 120-grit to remove any release agent.
2Edge grain bonds poorly — reinforce with splines, biscuits, or pocket screws.
3Check for delamination: tap the surface and avoid areas that sound hollow.
4High-pressure laminates (HPL) on plywood resist adhesion — sand through the laminate layer first.
