REKS® Nabryzg is applied by wet spraying when repairing elements of concrete and reinforced concrete structures and for rapid restoration of concrete surfaces in large volumes — in industrial buildings, on columns and beams. It is a non-shrink fibre-reinforced mortar of class R3 per GOST R 56378 with an aggregate size of 1.25 mm; flowability is retained for at least 20 minutes. At 28 days compressive strength is from 35 MPa, bond to the substrate at least 1.5 MPa, water impermeability W12, freeze-thaw resistance F2 200.
