Applications & Uses

Product Installllation

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 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.
