Quick-hardening mortar for repairing horizontal substrates
- it hardens quickly (technological movement on the surface is possible after 6 hours)
- resistant to moderate mechanical stress
- high adhesion to the base
- convenient and easy to use
- moisture and frost resistant
- fiber reinforced
Packing: 25 kg
The PRR-216 mixture is intended for the repair of strong undeformed horizontal concrete and cement-sand foundations inside and outside buildings. Effective for quick repair of potholes on concrete horizontal surfaces.
The thickness of the layer in one application is from 5 to 35 mm.
It is used for the repair of screeds, staircases and platforms, ramps, curb plates. Surfaces made of PRR-216 can be painted with special paints for concrete and serve as a floor covering.
