Application

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 floors shall be made good using a proprietary repair compound e.g. Centrecoat MMA 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 should 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 Centrecoat MMA Steel Primer shall be applied as soon as practicable after blasting, in order to obviate the possible occurrence of ‘flash rusting’.

Concrete surfaces shall be primed with a coat of Centrecoat MMA Multi-Use 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 Centrecoat MMA Steel Primer as soon as practicable after blasting.

Centrecoat MMA Smooth 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.

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.
