Surface preparation

The substrate must be solid, absorbent and dry and must not contain oil, wax or grease. With smooth or cement-rich substrates, the substrate must always be roughened. Moving cracks must be closed. Add component B completely to component A and mix with a slow running drill at max. 300 revolutions per minute during three minutes until a homogeneous mass is obtained. Cover with another layer within 24 hours, otherwise sprinkle with quartz sand.

Sustainability & Storage

MarrFill Floorprimer EC has a shelf life of 12 months, provided that opened buckets are properly closed and stored frost-free, not in direct sunlight, between 5°C and 25°C.
