StopGap Acoustical Sealant
Auralex StopGap
Acoustical Sealant is a highly elastic, water-based sealant used for reducing
sound transmission at the perimeter of wall systems or around electrical
box cutouts to achieve specified STC/MTC values. The surface dries to
a tough film but the sealant remains flexible and stays pliable for up
to 5 times longer than alternative brands. And unlike other products,
Stop-Gap has no residual run-off. StopGap is paintable and nonstaining,
and meets ASTM C-834 standards for flame retardancy (flame spread=0; smoke
developed=0).
Suggested
applications:
- Apply
in a 1/4" (6mm) bead around perimeter of sound related partition
- Apply
to depth as required for voids and larger openings
- Seal sound-rated
partitions on both sides where facings abut dissimilar materials
- Apply
to all openings formed for outlets and lights and completely cover the
outside of electrical boxes
