Metcon MCC 1121 is a solvented Epoxy Penetration Primer for concrete surface and is versatile for entire floor top coat series. It provides excellent adhesion between concrete surface and top coats. It has good penetration and sealing properties, good bonding with concrete and cementatious substrates.
It is recommended for new or old concrete surface before top coat application.
Before Primer application ensure that the concrete surface is clean dry and sound. Moisture test is conducted by moisture meter or plastic sheet method (ASTMD 4263 standard KA method for indicating moisture in concrete). The residual moisture should not be more than 4.5%.
Surface Preparation like scarification grinding or shot blasting is done to achieve a surface profile of 100 - 150 microns.
Application Method: Mix the base and hardner in the given ratio stir thoroughly for 5 - 7 minutes. Apply by roller or brush. Allow to cure for 8 hrs before screeding or top coating.
