- Product Highlights
- SpecSeal® Fast Tack® Firestop Spray is an elastomeric single component advanced hybrid polymer spray coating designed to provide passive smoke and fire protection in construction joints.
- SpecSeal® Fast Tack® Firestop Spray is engineered to adhere to common construction substrates and may be applied using airless spray equipment or with a brush (for small applications or touch ups). As an option, SpecSeal® Fast Tack® Firestop Spray may also be used as a self-leveling sealant and poured into the linear opening to the required thickness as specified in the individual UL System design.
- SpecSeal® Fast Tack® Firestop Spray dries rapidly and cures in the presence of atmospheric moisture to form a durable, flexible, water-resistant shield against the propagation of fire, smoke and combustion byproducts. SpecSeal® Fast Tack® Firestop Spray does not contain asbestos or PCB’s.

- Limitations
Use product as per manufacturer’s instructions. Use only in applications per the manufacturer’s published designs or specific recommendations. End user must ultimately determine the suitability of the product and/or design to his or her specific requirements and assumes responsibility for its use. Product is Conductive Until Dry. Do Not Apply in the Presence of Exposed or Energized Electrical Conductors.This product has been designed to be safe with plastics. It has been used extensively and successfully with various types of plastic pipes, tubes, and plastic cable insulations. Variations in these materials, however, make it impossible to guarantee compatibility. STI strongly recommends that the user consults with the pipe, tubing, or cable manufacturer in question regarding any known sensitivities or potential restrictions before applying this product.
- Maintenance
Inspection: Installations should be periodically inspected for subsequent damage. Following safety precautions listed below and pertinent installation guidelines remove coating in damaged areas and reapply fresh coating material to original coating thickness.
- Application Equipment
Notice: Spray application of SpecSeal® Fast Tack® AWG requires airless spray equipment meeting the following specifications:
- Working Pressure: Minimum 2500 psi (172 Bar)
- Delivery: Minimum 0.80 GPM. (3.0 lpm) recommended
- Spray Tip Orifice: 0.023” to 0.026” (0.58 mm to 0.66 mm) recommended
- Wetted Parts: All seals, hoses and contact surfaces should be Teflon®.
A minimum 3/8” diameter fluid line is required. Consult sprayer manufacturer for long hose runs or lifts to higher elevations. A reversible spray tip is recommended. A 6 inch fan pattern is suggested to minimize overspray. The following airless spray equipment has demonstrated suitability for application of this product. STI makes no warranties concerning the suitability or use of this equipment and has no affiliation of any kind with the manufacturer. The following equipment is manufactured by Titan Tool, Inc. Franklin Lakes, NJ.
