Working Conditions: For best results, apply in dry conditions above 40ºF (4ºC).

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 siding applications, place sealant under the fastener to prevent wind blown rain from leaking through the fastener holes.
