Solvent free, two component epoxy putty for repair of small cracks, air-pockets and/or blow-holes in concrete walls and floors. Mix base and activator carefully with a filling knife, preferably not in the can but on a flat substrate alike a piece of hardboard. Apply a slight over-amount of the Epoxy Putty with a filling knife or trowel; after drying reshape the surface by abrading the excessive amount.
