STI Optimizes SNS Acoustical Spray

SpecSeal^® Smoke ’N’ Sound (SNS) Acoustical Spray is engineered to seal gaps, seams and openings associated with smoke control and sound attenuation in non-fire-rated wall, floor and ceiling assemblies. It is formulated to adhere to all common construction substrates and can be applied using airless spray equipment or a brush for smaller areas and touch-ups.

SpecSeal^® SNS Acoustical Spray was the first acoustical spray of its kind, setting the standard in the industry. The latest updated SNS formulation continues that legacy with targeted refinements focused on application control, hangability, build consistency and finish quality.
