SECTION 03 0555 Fast Track-24
Specifier Notes: This section covers Valspar Flooring “Fast Track-24”.
Fast Track-24 is a concrete admixture that allows concrete to cure within 24 hours and be coated within this time frame, as opposed to waiting 60 days to apply coatings to concrete surface.
Fast Track-24 conforms to USDA guidelines for use in federally inspected meat and poultry plants.
Consult Federal Flooring for assistance in editing this section for the specific application.
