In older buildings, removing VCT often reveals black “cutback” adhesive. Beyond the potential asbestos issues (which require abatement), these old adhesives pose a chemical compatibility risk with modern flooring.
The Reaction Risk
Modern adhesives are often incompatible with old asphalt-based cutback residues. furthermore, high moisture levels can reactivate these old adhesives, causing them to bleed through new leveling compounds.
IFTI’s Assessment
When IFTI performs diagnostics on renovation projects, we don’t just test moisture. We document surface conditions. We flag the presence of old adhesives so that you can consult with your patch and coating manufacturers (like Ardex or Uzin) for the correct primer specification.
We provide the data; the manufacturers provide the chemical solution. Together, we ensure the new floor sticks.
