Elakor-PU Grunt Eko — food-grade polyurethane primer for food contact
One-component polyurethane primer for direct contact with food products and drinking water, applied in frost down to −30 °C.

This filled repair compound levels concrete, sand concrete, levelling compounds, stone and brick before installing epoxy and polyurethane floors, fills cavities, potholes and cracks, and forms slopes. It can be additionally filled with quartz or sand, with crushed stone for large defects, and with marble or dolomite for non-sparking coatings. Colour is approx. RAL 7013, like wet concrete, Shore D hardness 93–97, working time of the batch not more than 20 minutes.
