Thin concrete putty for warm surfaces
- for small repair of concrete and reinforced concrete structures
- withstands temperature increase when applied to the surface without preliminary priming (reinforced concrete panels after the steaming chamber)
- has a low shrinkage
- resistant to cracking
- water and frost resistant
- highly plastic, easy to apply and grouting
- suitable for interior and exterior work
Packing: 25 kg
The thin-layer PRR-228 putty is intended for leveling and filling of potholes, damaged places, small cracks and caverns on concrete and reinforced concrete structures.
Works effectively in a thin layer and on surfaces with highly absorbent properties without first priming at elevated temperatures up to + 45 ° C (for example reinforced concrete panels after
It can be applied on vertical and horizontal surfaces at external and internal
works, including painting and decorative plastering of building facades.
Not suitable for leveling of light and porous concrete, brickwork, lime and gypsum plasters. In one pass the mixture can be applied with a layer thickness of 0.2 mm to 7 mm.
