HVAC Mechanical Contractor Says Spray Seal is Life Changing
—Tim McNeff, Mid-Atlantic Mechanical Project Manager
“Using the Spray-Seal system is life changing…It’s faster, it’s cleaner and we’re using less product, plus every single test that I’ve done after spraying with Spray-Seal has passed, some with 0% leakage which is unheard of.”
—Ken Kendrick, Project Manager for Bright Sheet Metal
“We found that the Hardcast Spray-Seal System is a much faster way to seal ductwork…It’s more efficient, more cost effective and it does a better job.”
—Sisto Adame, HVAC Technician
“What normally took me 2-3 days to brush on sealant, now only takes 1 day, using less product, with Spray-Seal.”

Hardcast Line Set Protection Options
The TPO rolled mastic sealant is a 6.5 mil TPO membrane laminated to a butyl adhesive sealant to form a 22 mil composite. The TPO Line Set Wrap is applied by peeling off the release liner while covering the pipe wrap insulation. Since this membrane is 100% solid, there is no shrinkage or additional coats required due to absorption by the insulation. This gives the product superior protection against damage from moisture, landscaping, operations, equipment maintenance, and wind.
