Surface Preparation: All surfaces to be sealed should be free of dust, dirt, oil, and moisture before applying sealant.
Working Conditions: For best results, apply in dry conditions above 40°F (4°C).
Below 40°F (4°C) atmospheric condensation on surfaces may inhibit adhesion and should be avoided.
Application: Apply M5000 to surface directly from roll. Press sealant through the silicone release paper with a smooth, even hand motion.
Note: For metal roofing and siding applications, place sealant under the fastener to prevent wind blown rain from leaking through the fastener holes.
