Commercial Cork Flooring Warranty Coverage
Cork flooring installed in approved commercial environments is protected by the following warranties:

  • 5-Year Commercial Wear Warranty

  • Lifetime Structural Warranty

  • Lifetime Joint Integrity Warranty

These warranties apply only when the product is installed, maintained, and used according to all manufacturer instructions.

1. Commercial Wear-Through Warranty (5 Years)

The commercial wear warranty applies only when two additional coats of a high-quality commercial water-based polyurethane (such as LOBA 2K Supra AT) are applied on-site after installation.

Coverage includes:

The following are not covered under wear-through:

  • Loss of gloss

  • Minor scratches

  • Surface scuffs

  • Normal appearance changes from commercial traffic

2. Lifetime Structural Warranty

The flooring is warranted to be free from structural manufacturing defects for the lifetime of the product when used under normal commercial conditions.

3. Lifetime Joint Integrity Warranty

The locking system is guaranteed to remain secure under normal use.
Seasonal gaps up to 0.2 mm (0.01″) are considered normal for natural cork and are not classified as defects.
