Installing flooring over existing commercial substrates requires verifying that the base remains structurally sound and stable. Professionals must conduct a compatibility test to ensure new adhesives will bond to the old surface, or determine if a self-leveling underlayment is needed to create a new, uniform base. Additionally, testing for bond-breaking contaminants such as oils or previous wax applications is vital. Failure to confirm the substrate's condition can lead to bubbling, peaking, or delamination of the new flooring system.

What technical factors must be verified before installing flooring over existing commercial substrates?
Before installation over existing substrates, professionals must check for bond compatibility, structural integrity, moisture emission levels, and surface irregularities. Any existing flooring that is loose, damaged, or contaminated must be properly remediated or removed.
