Frequently Asked Questions
What openings is the SpecSeal Smoke N Sound 5 gallon pail made to seal?
Per the Indcon amfile Spray PDS (ZSFOD5131 23136), this 5 gallon product is Smoke N Sound Spray for static or minimally dynamic linear joints or gaps in non-rated barriers. Applications named on that sheet include smoke control in smoke partitions, noise control through wall openings, and infectious or dust control where airborne particulates must be reduced.
How do crews apply Smoke N Sound from the 5 gallon pail?
The Spray PDS calls for airless spray equipment meeting the published pressure, delivery, and tip orifice ranges, or a brush for small applications and touch-ups. Apply between 60 F and 90 F (16 C to 32 C). Typical wet film for the less-than-one-cfm air-leakage claim is 1/8 in to 1/4 in over appropriate backing. Wear site PPE, use adequate ventilation, and follow the Safety Data Sheet. Product contains water and is conductive until dry.
Is the live 5 gallon SKU SNS205 spray or SNS105W sealant?
Magento name and url_key say SNS205, and amfile 866 on this SKU is the Smoke N Sound Spray PDS whose ordering table lists SNS205 (UPC 730573011553). The sister sausage SNS120W uses the Smoke N Sound Sealant PDS (amfile 865), which lists SNS105W as the 5 gallon sealant pail (UPC 730573111543, approximately 70 lb). Sealant and spray are different chemistries and weights. Prefer amfile 866 for this SKU pending Manager confirmation; leave Magento name and url_key alone.
When should a crew choose Smoke N Sound instead of an intumescent firestop?
Smoke N Sound Spray is an acrylic latex smoke and acoustical coating, not an intumescent firestop. Choose it when the job needs smoke, sound, or particulate control at linear joints in non-rated barriers per the Spray PDS. When the published design calls for an intumescent firestop sealant, pillow, putty, or collar, choose that firestop product instead.
What temperature and dry times apply after the 5 gallon Spray is applied?
Application temperature is 60 F to 90 F (16 C to 32 C). In-service temperature is less than 185 F (85 C). Store unopened material at 40 F to 95 F (4 C to 35 C). The Spray PDS lists tack free in approximately 2 hours and dry through in 24 to 48 hours. Shelf life is 24 months from manufacture. VOC content is 30 g/L; STC is 61 on a specific construction.
What safety limit applies while SpecSeal Smoke N Sound Spray is still wet?
The PDS states the product contains water and is conductive until dry. Do not apply in the presence of exposed or energized electrical conductors. After dry it is water resistant and will not re-emulsify. Confirm any pipe- or cable-maker restrictions before install even though the formula has no solvents that might adversely affect plastic pipes or cable jackets.
