Product Installation

Surface Preparation: All surfaces to be sealed should be free of dust, dirt, oil, and moisture before applying sealant.

Working Conditions: 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 MB-10A to surface directly from roll. Press sealant through the silicone release paper with a smooth, even hand motion. Note: For metal roofing and cladding applications, place sealant under the fastener to prevent wind driven rain from leaking through the fastener holes.
