Elakor-MB3 Concrete and Metal Cleaner — chemical substrate preparation
Water-based concentrate for chemical removal of cement laitance from concrete before polymer coatings and for cleaning rust off steel.

Without pigment, the filler keeps its natural colour close to RAL 1013, so it is used under transparent and coloured coatings. This compound of two components mixed 8:1 by weight does not shrink, fills cavities, potholes, cracks and joints, and is also suitable for abutments and skirtings. It is applied with flat trowels neat or with dry sand onto concrete, sand concrete, tile, stone and brick at temperatures from +5 to +25 °C.
