Overview
HeatShield Adhesion Promoter is a clear, syrupy liquid additive for HeatShield Cerfractory Foam and HeatShield Cerfractory Flue Sealant. The inside of a chimney or fireplace is hard to clean, so this gives the mix the best chance of bonding to flue tile and masonry. It also improves strength by cutting the amount of water needed. Buy from StoveSource and pay no sales tax in any state.
