Profskrin RC 451 RLq — flowable R4 repair mortar for fast-track work
Flowable R4 mortar for urgent repair of road slabs, platforms, track concrete and grouting under bridge bearings; from 15 MPa after 2 hours.

The one-component polyurethane sealer is applied to freshly laid concrete or topping to reduce water evaporation while strength develops. The product is clear and can be applied at substrate temperatures from +5 to +35 °C; drying to degree 3 at +20 °C takes about 2 hours. The material is flammable: it must be applied without open flame and in a ventilated room. It is supplied in 23 kg containers.
