Directions for Use

Surface Preparation 

  • Concrete surfaces shall be a minimum of 21 days old and/or the residual moisture content shall be below 6%.
  • Ensure that the concrete is clean and free from dust, laitance, grease, oil, curing compound, and existing paint finishes, etc.
  • Blow holes and defective concrete shall be made good using a proprietary repair compound e.g. CPR 711 – MMA Concrete Patch Repair Mortar.
  • Suitable mechanical treatment, such as vacuum grit blasting, is the preferred treatment prior to application as this ensures a mechanical ‘key’ which will optimise adhesion.
  • Steel surfaces shall be shot blasted or grit blasted to a nominal Sa 2.5 Swedish Standard and with a medium blast profile.
  • All dust shall be removed prior to coating application.
  • A coat of CPR 412 – MMA Metal Primer shall be applied as soon as practicable after blasting, in order to obviate the possible occurrence of ‘flash rusting’.

Priming

  • Concrete surfaces shall be primed with a coat of CPR 406 – MMA Concrete Primer, applied by brush or roller at a nominal rate of 0.3kg/m².
  • Long nap lambswool rollers are recommended for primer application.
  • Allow primer to cure for a minimum of 40 minutes.
  • Steel surfaces shall be primed with CPR 412 – MMA Metal Primer as soon as practicable after blasting.

Mixing

  • CPR 709 – MMA Self Levelling Screed is supplied as a three pack material consisting of the Base component, the Catalyst component, and the Filler component.
  • Mix the BASE component and the CATALYST component thoroughly by mechanical means and then add the FILLER component, mix thoroughly until a uniform consistency is achieved.

Application

  • Pour the mixed material onto the prepared and pre-primed surface, and apply by serrated trowel or screed box to the desired thickness.
  • De-aerate the screed by spike rollering.
  • Note: Existing joints in the floor must be carried through the screed.
  • If a more slip resistant finish should be required, then a suitable aggregate shall be broadcast whilst the screed is still wet and a suitable sealer coat subsequently applied.

Equipment Cleaning

Curing

  • Allow a minimum cure time of 1 hour @ 20°C prior to foot trafficking.
  • For optimum chemical resistance, a minimum cure time of 24 hours @ 20°C should be allowed.

Overcoating
