Dur-A-Fast Repair Mortar is a rapid and cold curing, reactive polyurethane modified methyl methacrylate (MMA) based resin product designed for the formulation of repairing and rehabilitation of civil engineering and other concrete structure applications.
- Quick return of normal traffic and use of structure - faster turnaround of project.
- Reduces traffic and exposure of both workers and drivers to construction hazards
- Performance not effected by exposure to UV
- Long service life - withstands freeze thaw
- Cold Temperature Application, may be applied at low temperatures (-20oC)
- Zero VOC’s,
- Resistant to organic and inorganic chemical compounds and bacterial growth
- Chemical and abrasion resistant
- Easy to apply, easy to clean and sterilize
Dur-A-Fast Repair Mortar is typically designed for patches (up to 1” (25mm) thick), overlays and grouting of slabs. The cured system exhibits high early and ultimate strength in 1 hour. Dur-A-Fast Repair Mortar can be applied in a temperature range of -20oC to 30oC. Dur-A-Fast Repair Mortar is also used for repair of work or damaged concrete, repair of pre-cast concrete units, bedding and sealing concrete units, steelwork, road furniture, grouting in dowel pins, rag bolts, holding down bolts, starter bars and for fixing tiles, slabs, precast facings.
