Material Use:
SOPRASEAL SEALANT is a solvent-free, low-VOC, moisture-cure polyether (STPE) sealant designed for use as a waterproofing accessory in wall assemblies, plaza decks, foundations, and parking decks. It is primarily used as a termination sealant and for filling and repairing horizontal and vertical voids in concrete and masonry substrates, with a maximum joint width of 13 mm (1/2"). The product is compatible with SOPRASEAL membranes and is ideal for sealing joints and penetrations in building envelope systems.
System Components:
SOPRASEAL SEALANT is typically used in conjunction with SOPRASEAL membranes as part of a complete air and moisture barrier system. It acts as a detailing and termination component, ensuring continuity of the waterproofing layer at transitions, penetrations, and terminations. No primer is generally required, but surfaces must be properly cleaned to ensure adhesion.
Applications:
This sealant is suitable for use on a wide range of construction substrates including aluminum, metal, concrete, masonry, and plastics such as PVC. It is commonly applied in wall assemblies, plaza decks, foundations, and parking decks where flexible, durable, and weather-resistant sealing is required. It is especially effective in detailing work around windows, doors, pipe penetrations, and other complex geometries.
Application Details:
SOPRASEAL SEALANT is applied using standard caulking guns. The substrate must be clean and dry, free of dust, grease, oil, and other contaminants. Metal and PVC surfaces should be cleaned with non-greasy solvents like acetone or methyl ethyl ketone (MEK). The sealant cures by moisture and has an initial skin time of 30 minutes to 1 hour, with full cure achieved in 24 hours depending on ambient temperature and humidity. Application should be performed at temperatures above 0°C (32°F), and the cured product can withstand service temperatures ranging from -40°C to 93°C (-40°F to 200°F).
Special Notes:
- SOPRASEAL SEALANT meets ASTM C920 standards (Type S, Grade NS, Class 25, Uses NT, T, M, G, A, and O), ensuring high performance in a variety of sealing applications.
- The product has excellent elongation (300%) and tensile strength (2.4 MPa / 350 psi), providing long-term flexibility and durability.
- It is UV resistant after cure, making it suitable for exposed applications.
- The sealant is supplied in 300 ml (10.1 oz) and 600 ml (20.2 oz) cartridges, with coverage of approximately 12 linear meters (40 linear feet) or 24 linear meters (80 linear feet) respectively when applied in a 5 mm x 5 mm (3/16 in. x 3/16 in.) bead.
- Shelf life is 12 months when stored in original, unopened containers in a cool, dry place away from direct sunlight and heat.
- Uncured material and tools can be cleaned with alcohol-based cleaning products.
SOPRASEAL SEALANT is a reliable and versatile accessory product that enhances the performance of SOPREMA’s waterproofing and air barrier systems, ensuring long-lasting protection in demanding construction environments.
