acoustic mastic

Acoustic sealent for all soundproofing treatments Intumescent acoustic sealant is ideal for using with many of our soundproofing products. It is paintable and provides over 10 linear meters per tube. The Acoustic Sealant is a white one-part Fire Retardant, intumescent Water-based Acrylic Sealant. It has a 4 hour fire rating so is ideal for sealing holes in ceilings, floors and walls. It is paintable with emulsion paints three hours after application but allow 12 hours before over painting with gloss paints. When subject to fire our sealant will intumesce (expand and char), creating a barrier to fire and smoke.
