- high adhesion to concrete (not less than 2.0 MPa)
- crack resistant
- frost resistant
- microfiber reinforced
- convenient and easy to use
Packing: 25 kg
The PRR-222 mixture is intended for repair and restoration of concrete and reinforced concrete structures. Effective for repairing chips, voids, sinks, bumps and other defects on the surfaces of reinforced concrete and concrete substrates, with a layer thickness of 10 to 100 mm.
! Do not use for leveling and repairing light concrete substrates.
The PRR-222 mixture is an integral part of the concrete recovery and protection system.
It is used in the comprehensive repair of concrete and reinforced concrete structures caused by long-term operation under the influence of mechanical loads and corrosion processes – monolithic structures, retaining walls, tanks, ramps, ramps, balconies, etc.
