Practical Notes

Ensure the adhesive used matches the intended exposure (MR for dry interiors, BWP for damp or high-humidity areas).

Decorative veneer matching patterns (e.g., book match, slip match) are not strictly standardized and must be explicitly agreed upon between the buyer and manufacturer.

Face veneers should be carefully inspected for permissible defects to ensure aesthetic quality matches project requirements.
