Concrete Surface Contamination (Concrete / Substrates)
Floor Detective® Claims and Conditions Guide
Summary
Concrete surface contamination refers to foreign materials on or within the slab surface that interfere with flooring adhesion, surface preparation compatibility, or bond performance. Contaminants may include curing compounds, sealers, adhesives, oils, paint, construction debris, or residue from prior flooring systems. These materials may reduce surface porosity, prevent adhesive wetting, or create a bond-separating layer at the flooring interface. Surface contamination affects flooring-system performance by limiting adhesion and compatibility rather than indicating a defect in the flooring material itself. See also Surface Contamination and Bond Inhibition, Concrete Surface Profile and Surface Preparation, and Concrete Substrate Problems.
