SpecSeal® Smoke ’N’ Sound Acoustical Spray is a high‑performance, water‑based acrylic latex spray formulated to seal gaps, linear joints, and openings associated with non‑fire‑rated penetrations in non-fire-rated wall, floor, and ceiling assemblies. Engineered for fast and uniform application, SNS Acoustical Spray delivers an effective seal that helps limit the passage of smoke, airborne particulates, and sound through construction interfaces. When properly installed, SpecSeal Smoke ’N’ Sound Spray forms a flexible, durable coating that accommodates normal building movement without cracking or loss of adhesion. The material can be applied in thicker sections—up to approximately 5/16 in.—making it suitable for a wide range of construction gaps and acoustic sealing requirements. Ideal for commercial and multifamily projects, SNS Acoustical Spray provides a clean and efficient solution for enhancing air sealing, smoke control, and sound attenuation in non‑fire‑rated assemblies.
