Yellowing / Intrinsic Discoloration (LVP / SPC / WPC)

Floor Detective® Claims and Conditions Guide

Summary

Yellowing or intrinsic discoloration in luxury vinyl plank (LVP), stone polymer composite (SPC), and wood polymer composite (WPC) flooring involves internal amber, yellow, or tonal color shift developing within the wear layer, coating system, or polymer structure rather than from direct external staining. In modern rigid-core flooring systems, true intrinsic polymer-related yellowing is uncommon because of improved ultraviolet stabilizers, mineral-filled core technology, and advanced urethane coating systems. Most reported discoloration conditions involve contact-transfer staining, environmental exposure, maintenance chemistry, or contaminant interaction rather than internal material instability. Distribution pattern, exposure history, and absence of contact-transfer geometry are important diagnostic indicators. Proper evaluation requires elimination of more common external staining pathways before intrinsic material discoloration is considered.
