• BroFix is ready to apply in 5 minutes and becomes a permanent repair quickly.

• Select the BroFix repair stick that best matches the original material that you plan on repairing or modifying

• Cut off a piece from the stick that best matches the size of the job.

• Knead the BroFix repair material with your fingers until uniform in color and apply. BroFix hardens very quickly but can still be worked and smoothed during this hardening process allowing for precise positioning. 

• After curing BroFix can be tapped, screwed, drilled, sanded, sawed, filed or painted

• Void and porosity filling

BroFix has excellent adhesion and bond strength to fiberglass, epoxy and graphite composite mold surfaces as well as aluminum and steel. Easier and faster than set-fast filler pastes.


BroFix provide a smooth, creamy and workable paste with superior handling, set-fast characteristics and dimensional stability. Once applied it forms a rigid, strong surface, which can be machined, sanded, filed or scraped to a feather edge.


BroFix adheres and bonds to fiberglass, SMC, RIM, BMC, Graphite, Kevlar™ and other types of composites as well as aluminum, steel, grey iron, copper, plaster, models, patterns and other substrates.


BroFix can be applied without pin-holing and exhibits no shrink or sink after curing. It accepts virtually all types of finishes e.g., lacquer, enamel, polyurethane, epoxy, etc., without any special preparation. It is a "no bleed out" system after finishing or if covered with a decorative film.

• Make quick & permanent repairs in 5 minutes

• Indefinite shelf life

• Good for large or small mold repairs

• Quickly prototype/fabricate
