Do not assume compatibility
Installing new flooring over an unknown adhesive can conflict with manufacturer requirements.
Hazardous materials
Older buildings may contain hazardous materials in flooring systems or adhesives. Suspect materials should be assessed by qualified professionals before disturbance.
Preparation scope
Grinding, removal, encapsulation or other approaches depend on the actual material and specified new system.
Budget allowance
Unknown adhesive is a reason for investigation and contingency, not for improvised on-site treatment.
Commercial flooring decisions depend on the actual substrate, moisture conditions, traffic, cleaning regime, accessibility requirements, fire/building rules, manufacturer instructions and local code. This site is for planning and comparison, not installation instructions.
