Expert Verdict Reviewed by the SuperArbor Pro Desk

Smoke ‘N’ Sound Spray is the economical choice for sealing linear gaps where smoke partitioning, privacy and dust control matter but no fire rating is required. Airless spray gives the fastest production on long joint runs, while brush application suits small gaps and touch-ups. Keep application temperatures between 60 and 90F for proper film formation.

Apply in ventilated conditions at 60-90F and consult the product SDS before use; California residents should review the Proposition 65 warning.
