Description
Single-component polyurethane foam designed to withstand sunlight and blend naturally into the landscape. Recommended for outdoor use as a sealant or filler.
UNITS PER SKID: 960
VOLUME: 500ml
Material Use:
SOPRA-FOAM OUTDOOR SEALANT is a single-component, moisture-cured polyurethane foam designed for outdoor sealing and bonding applications. It is particularly suited for use in landscaping and decorative construction tasks such as bonding stone and concrete, managing water flow in ponds and waterfalls, crafting, and securing artificial plants in pots. Its black colour is formulated to blend naturally into outdoor environments, even when exposed to sunlight.
System Components:
This product is a standalone system and does not require additional primers or base coats. It is supplied in a 500 ml straw-applied cartridge and is ready to use after shaking. For cleaning uncured foam, SOPRA-FOAM CL-F cleaner is recommended. No topcoat or final coat is required, although the cured foam can be sanded, painted, or stained after 24 hours if desired.
Applications:
SOPRA-FOAM OUTDOOR SEALANT is ideal for outdoor construction and landscaping applications where a durable, weather-resistant seal or bond is required. It adheres well to a wide range of substrates including vinyl, wood, metal, polystyrene, and polyisocyanurate. It is commonly used in decorative stonework, water feature construction, and general outdoor sealing tasks.
Application Details:
- Surface Preparation: Surfaces must be clean, dry, and free of contaminants such as oil, dust, and loose particles. Cement laitance must be removed. Porous surfaces should be lightly moistened with water before application.
- Application Method: Shake the cartridge well before use and intermittently during prolonged application. Attach the straw applicator and apply the foam while holding the cartridge downward. Apply in layers no thicker than 25 mm (1 inch) to allow for proper expansion and curing. In dry conditions, multiple thin layers are recommended. Water misting can be used to accelerate curing.
- Temperature Range: Application is possible between -6 °C and 30 °C (21 °F to 86 °F). For optimal performance, condition the cartridge to approximately 20 °C (68 °F) for 12 hours prior to use.
- Pot Life / Tack-Free Time: Approximately 6 ± 2 minutes at 23 °C and 50% RH.
- Trim Time: ≤ 40 minutes.
- Curing Time: 24 hours.
- Full Service Temperature Range: -40 °C to 80 °C (-40 °F to 176 °F).
- UV Resistance: The foam is not UV stable; prolonged exposure to UV rays may cause discolouration. Painting or staining is recommended for long-term UV exposure.
- Thickness Limits: Apply in layers ≤ 25 mm (1 inch) to ensure proper expansion and curing.
- Coverage / Yield: Approximately 19 L per gallon (yield may vary depending on surface roughness, temperature, and humidity).
Special Notes:
SOPRA-FOAM OUTDOOR SEALANT is not suitable for use on silicone or PTFE substrates and should not be used in applications requiring fire-retardant or fireproof materials. Once cured, the foam is inert and must be removed manually if needed. The product has a shelf life of 18 months when stored upright in its original packaging in a dry environment between 5 °C and 25 °C (41 °F to 77 °F), away from direct sunlight. Always refer to the most recent Safety Data Sheet (SDS) for safe handling and disposal information.
