Airlok® STPE Gun-N-Spread

Airlok® STPE Gun-N-Spread is a single-component, gun and trowel cold-applied Silyl Terminated Polyether (STPE) fluid flashing material; that combines the best of silicone and polyurethane properties. Typically used as a fluid-applied, troweled on above grade rough opening flashing/waterproofing used prior to installation of doors and windows.

FEATURES & BENEFITS

  • Versatile putty-knife application as window opening flashing
  • Can be used on damp or wet surfaces
  • Unlike silicone products, Airlok STPE is compatible with virtually all common Building Materials
  • Single-component; ease of application with no need for mixing
  • Existing cured membranes readily receive additional application creating a monolithic transition
  • Wide range of application temperatures from 25°F (-3°C) up to 110°F (44°C)
  • Resistant to wash-off during rain events, extending the application time relative to inclement weather
  • High solids content of 100% for high yield and  <20 g/l VOC
  • Compatible with most known building materials
  • Long term exposure to the sun’s ultra violet (UV) rays for a period up to nine (9) months
  • Long term physical durability and chemical stability as a liquid applied air barrier system
  • Compliant with NFPA 285 in most wall assemblies
