Product Highlights
  • SpecSeal® LC Sealant is a latex-based, high solids firestop compound. This material, when properly installed, will effectively seal penetration openings and joints against the spread of fire, smoke, hot gasses and water.
  • SpecSeal® LC Sealant is engineered to adhere well to virtually all construction surfaces and may be applied using a standard caulk gun or by troweling with a standard mason’s trowel or with a putty knife.
  • SpecSeal® LC Sealant dries to form a flexible shield against the propagation of fire. Its premium latex binder system is totally resistant to water and will not re-emulsify after drying.
  • SpecSeal® LC Sealant is non-halogenated, contains no asbestos or inorganic fibers.
Features
  • Installer Friendly, easily applied with standard caulking gun
  • Can be troweled on for larger applications
  • Tested for up to 4 Hours of fire resistance when tested to ASTM E1966/UL2079, ASTM E814/UL1479, and CAN/ULC-S115
  • Listed in over 80 UL Tested Firestop Systems!
  • UL® GreenGuard Gold Certified

Applications

SpecSeal® LC Sealant is designed primarily for sealing construction joints and gaps as well as penetrations for noncombustible penetrants. SpecSeal® LC has been tested and approved for single metallic pipe penetrations up to 30” (762 mm) as well as multiple penetrants through both masonry and gypsum wallboard constructions. Additional systems have been tested for steel sleeved penetrations as well as some common electrical and communications cable penetrations and joint penetrations.

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. Any damage should be repaired using SpecSeal® LC Sealant as per the original approved design. Retrofit: When adding or removing penetrants, care should be taken to minimize damage to the seal. Reseal using SpecSeal® LC Sealant as per the approved design. NOTE: New penetrants of a different nature than the original design may require a totally new firestop design or extensive modifications to the existing design. Reseal openings as per the requirements of the modified design.

Performance

SpecSeal® LC Sealant is the basis for systems that meet the exact criteria of ASTM E1966 (UL2079) and CAN/ULC-S115 as well as the time-temperature requirements of ASTM E119. Tested systems will provide up to a 3 hour rating utilizing as little as 1/4” (6 mm) of sealant depth (1/2” (13 mm) for 4 hours). All tested systems have been cycled 500 times at total movement up to +/- 12.5% or 25% in compression only.
