MBA Adhesive

#107 MBA Adhesive is a specially formulated blend of select asphalts, mineral fibers, solvent and cohesive materials. Manufactured to a thick, brushable consistency, it provides lasting adhesion and a watertight seal to layers of cold applied, asphalt coated, rolled roofing.

Uses
GlobalShieldä #107 MBA Adhesive may be used as a cold process adhesive for SBS modified bitumen membranes to smooth asphalt surfaces and as an adhesive for smooth roll roofing up to 65 pounds, an adhesive for half lap selvage edge roofing, and as a weatherproof maintenance coating for sloped roofs.

Advantages
#107 MBA Adhesive is easy to apply and provides excellent substrate adhesion and strong lap bonds. May be used with SBS modified bitumen membranes, coated fiberglass or coated polyester base sheets.

Installation
Coverage
Product yield to achieve desired rate will be from 2 to 4 gallons per 100 square feet. The yield varies according to the existing surface texture. As a general rule, the smoother the surface, the less material is required. This coverage is per coat or ply.

Surface Preparation
Remove all dirt, dust, debris and standing water by brooming and by forced air where necessary and where no danger or nuisance is caused to areas adjacent to work. All loose gravel must be removed from ballasted roofs. Scrape back to a hard edge all loose or scaled coating. Make all necessary repairs to existing surface prior to coating. Split seams, blisters and cracks in existing surface should be repaired with #102 Roof Cement and reinforced with Polyester Mat. Heavily weathered or exposed felt surfaces, as well as concrete, masonry or rusted metal should first be primed with #101 Asphalt Primer. Metal roofs should be allowed to weather for six months prior to coating.

Application
Apply by pouring directly from the container and spreading with a standard roofing brush. Be sure to spread product evenly. For polyester fabric installation, apply a first coat of Cold Process Adhesive to roof surface at 2 to 4 gallons per 100 square feet. Imbed the roofing ply/plies in wet material, taking care to smooch out any wrinkles. Overlap 4" on parallel seams and 6" on end seams. Apply a finish coat of Cold Process Adhesive at 2.5 to 5 gallons per 100 square feet. Note: When using Type II or Type III fiberglass base sheets, cut the plies in 18 to 20 foot long sections and allow to relax a minimum of 30 minutes prior to installation.

#107 MBA Adhesive cleans up with mineral spirits, but do not thin the product with this or any other solvents.
