What is Mulco Supra Expert used for?
Outdoor joints between two perpendicular surfaces that move with temperature: door and window frames, sidings and glass in window frames. Mulco lists concrete, masonry, painted or stained wood, aluminium, steel, galvanized steel, glass, fibreglass and PVC as substrates it adheres to, and says exterior use only.
Is Mulco Supra Expert paintable?
Yes. Mulco says it does not require painting, and that it can be painted with latex paint more than 24 hours after application. Wait the full day before the painter follows you.
How do you apply Mulco Supra Expert?
Gun it with a manual or pneumatic caulking gun, with the product between 5 and 30 °C and the surface between -30 and 40 °C. Mulco caps the joint at 16 mm wide by 10 mm deep and sets the minimum at 6 mm in both directions. At application the product is flammable, and its flash point is 28 °C.
How does Supra Expert differ from Supra Elite?
Supra Expert is a thermoplastic that dries by solvent evaporation and Mulco rates it exterior only. Supra Elite is a hybrid and Mulco clears it for outdoor or indoor joints, excluding floors.
