FORM RELEASE AGENT FOR ARCHITECTURAL CONCRETE

Specifier Notes: This specification is for the use of DEBOND FORM COATING to produce architectural concrete surfaces without bugholes, stains or residue. Though DEBOND is formulated to produce superior results, it is economical enough to be used on less demanding applications. Therefore, for simplicity, economy, and expediency, DEBOND FORM COATING may be used on the entire project rather than having additional release agents on a job-site.
