Carlisle Hardcast 319889 Low Voc Primer 1 Quart

Product Description

The CARLISLE HARDCAST 319889 is a low VOC primer supplied in a 1-quart container, designed for surface preparation in duct sealing and HVAC fabrication applications. Low VOC formulations meet increasingly strict air quality regulations on job sites and in occupied buildings. This primer is applied before sealants or mastics to promote adhesion to sheet metal and other duct surfaces. HVAC technicians and sheet metal mechanics use this product as part of a complete duct sealing system during new construction and retrofit work.

This primer is suited for commercial and residential HVAC duct system applications where proper surface preparation is required before applying compatible mastics or sealants. It is typically used on galvanized steel, sheet metal, and similar duct substrate surfaces prior to sealant application. The 1-quart size is well suited for smaller jobs or for technicians who need a portable, job-site-ready container.

Key Features

• Low VOC formula supports compliance with air quality regulations in occupied and commercial spaces
