- Product Highlights
- SpecSeal® Safing Spray is a high solids, latex-based elastomeric coating specifically formulated for slab edge safing applications.
- SpecSeal® Safing Spray is designed to be applied using airless spray equipment or by brush or roller. It is formulated to bridge gaps or irregularities over the mineral wool safing, and is ideally suited to work around curtain wall mounting anchors thereby enhancing productivity in even the most demanding construction environments.
- Utilizing a premium latex binder system, it is totally resistant to water and will not re-emulsify after drying. Upon drying, it forms a flexible barrier against the spread of fire, hot gasses, and smoke. It does not contain inorganic fibers, asbestos, or solvents.
- Features
- Bridges gaps and irregularities in mineral wool safing
- Tough polymer designed to resist damage from construction debris
- Tested for up to 4 Hour fire resistance when tested to ASTM E2307
- Listed in over 100 UL Tested Curtain wall Systems
- UL® GreenGuard Gold Certified

- 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 Contains Water and 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 inspected periodically for subsequent damage and repaired accordingly. If the packing or forming material is damaged, it should be removed and replaced maintaining the required compression. Reapply fresh coating to the original specified wet thickness.
- Application Equipment
Notice : Spray application of SpecSeal Elastomeric Spray requires airless spray equipment meeting the following specifications:
- Working Pressure: Min. 2500 PSI (172 Bar), Delivery: Min. 0.72 U.S. gpm (2.7 lpm) recommended
- Spray Tip Orifice: 0.023 in (0.58 mm) in to 0.026 in (0.66 mm) recommended
Wetted Parts All seals and contact surfaces suitable for contact with latex emulsions.
A minimum 3/8 in (9.5 mm) fluid line is required, a 1/2 in (13 mm) line is preferred. Consult pump manufacturer for long hose runs or lifts to higher elevations. A reversible spray tip is recommended. A 6 in (152 mm) 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 its manufacturer.
