Specially formulated to offer superior adhesion and sealing properties, our Rockwool Acoustic Sealant Trowel Grade 5kg is ideal for use in walls, partitions and glazing systems. Its smooth consistency ensures that it spreads evenly and fills all gaps and crevices to provide a fully sealed acoustic barrier.  

The sealant can be applied using a trowel, or it can be pumped using a standard mastic gun. Once applied, it dries to a flexible finish that can withstand structural movements and vibrations. This acoustic sealant also protects against fire, offering up to 4 hours of fire protection.
