The Strength of Diamond. The Confidence of a Lifetime.
Dymond Coatings are engineered with the same qualities as their namesake — tough, long-lasting, and built to bond for life. That’s why we back every eligible Dymond kit with our Lifetime Promise: if your floor fails due to a verified product defect, we’ll replace the material or issue a credit toward your next job. This warranty applies to complete Dymond systems (primer, base coat, and topcoat) when installed on indoor concrete surfaces and applied according to Dymond’s preparation and application guidelines. Covered issues include delamination caused by faulty resin blends, curing failure due to batch defects, and contamination introduced during manufacturing or packaging. To qualify, the product must be within shelf life, used under proper storage conditions, and installed using only Dymond components.
This warranty does not extend to issues arising from improper surface preparation, substrate contamination, excessive moisture vapor, impact or abuse, substrate movement, or UV discoloration of white/light epoxies. Installations over wood, tile, or outdoor surfaces are excluded unless specifically approved. Cosmetic issues such as texture variation, microbubbling, or minor tint shift are not covered. Warranty coverage is limited to the original purchaser and is non-transferable. Claims must be submitted with photographic evidence of each install stage and full batch documentation. Dymond reserves the right to determine whether the cause of failure falls within warranty scope.
This Promise applies to most DIY and light commercial indoor projects. Larger commercial and industrial installations may be eligible for custom coverage — contact us for terms.
