Coverage
- A 10kg pack yields 5 litres of mortar, sufficient for 1m² @ 5mm thickness
Surface Preparation
- Remove all laitance, spalled concrete, grease, oil, dust, and other contaminants by scabbling, bush hammering, or other mechanical treatment, to provide a sound clean substrate
- Any exposed reinforcing steel shall be fully exposed by cutting out around its full circumference, and cleaned by hand abrading or wire brushing to remove rust, scale, etc., and primed with a coat of 706 MMA Floor Primer
Priming:
- The prepared concrete surface, together with the pre-primed re-bars, shall be primed by the application of 706 MMA Floor Primer
- The mixed 706 MMA Floor Primer should be applied by brush or roller at a nominal rate of 0.2 – 0.3kg/m², depending upon surface profile
- Allow the primer to cure for a minimum of 40 minutes
Mixing:
- 710 MMA Repair Mortar is supplied as a three component product consisting of the base component, the catalyst component and the aggregate component
- The contents of the base and catalyst component should be thoroughly mixed together and the aggregate then introduced
- A low speed drill stirrer or a forced action mixer such as a Mixall, Pennine or Creteangle type, will be suitable
Mixing Ratio:
- (% Catalyst by Weight) = 2.5
Application
- 710 MMA Repair Mortar should be applied by tamping and trowelling to ensure good compaction and a tight finish
- The material should not be feather edged
- Minimum application thickness is 4mm
Cleaning
Curing
- Allow a minimum cure time of 1 hour @ 20°C prior to foot trafficking and 2 hours @ 20ºC prior to full trafficking
Limitations
- Do not apply to wet, uncured or unprimed concrete surfaces
710 MMA Repair Mortar will taint food during application, so that all foodstuffs in the immediate vicinity must be removed or properly covered.
