Technical overview

SOPRAMASTIC is a black, solvent-based mastic containing SBS modified bitumen, fibres and mineral fillers. It is a complement for bituminous waterproofing membranes and is used as a jointing mastic, caulking material and joint filler. It has excellent adherence on most materials without primer and can be applied to damp surfaces. The high polymer level is there to resist flow at high temperatures, and it stays easy to manipulate down to -10 C. SOPREMA states that SOPRAMASTIC meets the requirements of CAN/CGSB-37.5-M89 and ASTM D4586. Those are Canadian and American standards. No AS or AS/NZS test report is cited, no accredited certificate is held, and the data sheet states that all values are nominal.

Key applications

Jointing mastic
Caulking material
Joint filler
Complement to bituminous waterproofing membranes
Sealing on damp surfaces without primer

Surface suitability

Bituminous waterproofing membranes (compatible with bituminous materials)
Clean, sound substrates
Most materials without primer
Damp surfaces

SOPRAMASTIC must be applied to clean, sound substrates and should not be used as a pitch pocket filler. Application temperature range is -10 to 35C and service temperature range is -40 to 80C. Setting takes between 4 and 24 hours depending on temperature and the quantity applied. SOPRAMASTIC is a flammable product; store in a cool, dry area and consult the material safety data sheet prior to use. All published values are nominal. The standards cited are CAN/CGSB-37.5-M89 and ASTM D4586, both overseas standards, and no accredited Australian test report is held.
