Centrecoat Fastpatch is a blend of epoxy resin, polyamine curing agent, graded aggregate and colour pigments. The mixed material is applied to a suitably prepared surface, and quickly cures to form a durable, abrasion and chemical resistant repair.


Remove all laitance, spalled concrete, grease, oil, dust, and other contaminants by scabbling or bush hammering, to provide a sound, clean, substrate. Any exposed reinforcing steel shall be fully exposed by cutting out around its full circumference, and cleaned by abrading or grit blasting to remove rust, scale, etc.

Primer not normally required. For exceptionally porous surfaces, please contact our Technical Department for specific advice.

Centrecoat Fastpatch is supplied as a two component pack. Each component is pre-weighed and ready to mix. The contents of the CURING AGENT should be
added into that containing the BASE and the two components thoroughly mixed, by spatula or low speed drill/stirrer, or forced action mixer.

Apply the Centrecoat Fastpatch by tamping and trowelling to ensure good compaction and a tight finish. The material should not be feather edged. Maximum thickness in horizontal applications is 50mm. For vertical applications the material may be built up in layers not exceeding 6mm.

Clean equipment with Centrecoat MMA Tool Cleaner prior to curing of the mortar.
