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.
Airlok® STPE Gun-N-Spread
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
