What is Mulco Supra Elite used for?
Joints between two perpendicular surfaces: door and window frames, wall sidings, and the butt joint where siding lap boards meet. Mulco clears it for outdoor or indoor joints, excluding floors, and names wood, vinyl, aluminium, cement board and fibreboard sidings, cured concrete, brick, masonry, steel, copper, brass, glass, ceramic tile, fibreglass and PVC as substrates.
Is Mulco Supra Elite paintable?
Yes, with two conditions from Mulco. Wait more than 24 hours after application, use a latex paint, and test compatibility first. The translucent grade cannot be painted at all.
How cold can you apply Mulco Supra Elite?
Mulco allows the product itself between -10 and 40 °C and the surface between -25 and 50 °C. Flextra and Supra Expert both need the product above 5 °C. Once cured it stays flexible down to -50 °C, and Mulco records a pass at -30 °C under CAN/CGSB-19.0-M77 method 11.1.
How does Supra Elite differ from Supra Expert?
Supra Elite is a hybrid and Mulco clears it for outdoor or indoor joints, excluding floors. Supra Expert is a thermoplastic that dries by solvent evaporation and Mulco rates it exterior only. Supra Elite also goes on colder, down to -10 °C for the product against Supra Expert's 5 °C, and holds to -50 °C in service against -40 °C.
What joint size does Supra Elite take?
Mulco caps the joint at 25 mm wide by 12 mm deep and sets the minimum at 6 mm in both directions. The sheet's coverage table is worked out per 300 mL cartridge, and it lists no packaging, so ask the counter which sizes Cranco carries.
