Description

Resbuild MMA Colour Coat is a two pack, fast curing coating designed to provide a dust-free, seamless floor finish with protective and decorative properties.  The inherent slip resistance of the coating may be enhanced by the incorporation of a suitable anti-slip dressing aggregate.

Procedure

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. Resbuild MMA Floorpatch.  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.

All dust shall be removed prior to coating application.

A coat of MMA Steelprime 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 Resbuild MMA 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 Resbuild MMA Steelprime as soon as practicable after blasting.

 

Mixing

Resbuild MMA Colour Coat is supplied as a two pack material consisting of the RESIN component, and the CATALYST component,.

Incorporate the CATALYST component into the BASE component under mechanical stirring, and mix for 1-2 minutes.

 

Application

Apply Resbuild MMA Colour Coat using short nap perlon, or smooth lambswool rollers at a nominal rate of 0.30kg/m².  Following a minimum of 1 hour apply a second coat at the same nominal rate.  Should a slip resistant or skid resistant finish be required then broadcast an appropriate aggregate onto the first coat within 10 minutes of application.  Following a minimum of 1 hour, sweep off excess aggregate and apply a second coat of Resbuild MMA Colour Coat.

NOTE:  Resbuild MMA Colour Coat may be applied at greater thicknesses should service conditions warrant it.

 

Equipment Cleaning

Clean equipment with Resbuild MMA Toolclean immediately after use.
