CarbonWrap® Putty S two-component epoxy putty — summer version from +10 °C

Composite strengthening

CarbonWrap Putty S is used to prepare the surface for the external reinforcement system: to repair small defects and cracks, level the substrate and install carbon rods. The components are mixed at a ratio of 100:15 by weight to a uniform grey colour and applied with a spatula without a separate primer, and work can continue after 24 h at +23 °C. This is the summer version for air temperatures from +10 °C; the bond to concrete is more than 2.5 MPa, and the kit weighs 31 kg.
