Directions for Use
- 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. Metal substrates shall be degreased and grit blasted to Sa 2.5 Swedish Standard.
- Apply a coat of CPR 403 – Primer for Concrete Repair Mortars – Epoxy WB by brush or roller at a nominal rate of 3.5 to 7.0m²/kg, depending upon surface profile.
- The use of mechanical, forced action mixer such as a Creteangle, is strongly recommended.
- Pour the contents of the CURING AGENT container into the BASE container and mix thoroughly.
- The mixed resins shall be poured into a mixing vessel, (Creteangle bucket or similar), and the AGGREGATE added steadily whilst the mixer is in motion.
- Mix for 2-3 minutes until a uniform material is achieved.
- CPR 718 – Epoxy Concrete Repair Mortar shall be applied whilst the primer is still ‘tacky’ i.e. within 2 hours of application.
- The material should be tamped and trowelled to ensure good compaction and a tight finish.
- Minimum application thickness is 10mm; maximum application thickness is 50mm for large areas.
- Note: up to 100mm thickness may be applied in small patches.
- Clean equipment with CPR 201 – Tool Clean Solvent prior to curing of the coating.
- CPR 718 – Epoxy Concrete Repair Mortar will have hardened sufficiently after overnight cure @ 20°C. to allow overcoating or full trafficking.
- Longer periods of cure will be necessary at lower temperatures.
- Full mechanical and chemical resistant properties will be achieved following 7 days cure @ 20°C.
