Poly Beads (Hardwood Flooring)

Floor Detective® Claims and Conditions Guide

Summary

Poly beads are small rounded accumulations of finish material that appear along hardwood flooring board joints or seams after finishing. The condition develops when liquid finish settles into gaps between boards and later becomes displaced upward as the coating cures and the wood responds to changing moisture conditions. Poly beads are commonly associated with site-finished hardwood flooring and reflect finish behavior, joint spacing, curing characteristics, and normal dimensional movement within the flooring system. Visibility may increase under reflective lighting or with higher-gloss finishes. The condition is cosmetic in nature and does not involve structural wood failure or adhesive bond separation. See also Peeling Finish, Bubbles in Finish Hardwood, and Hardwood Floor Problems for broader context.
