Profskrin RC80 Lq — flowable R4 repair mortar for concrete of class B60 and above
Flowable R4 mortar for structural repair of B60 concrete and above; at least 35 MPa after 24 hours and 80 MPa after 28 days.

The finishing mortar Profskrin RC30 PSm has an aggregate size of only 0.315 mm, and fibre is included in its formulation. It is used for structural repair of load-bearing building and bridge structures, treatment and industrial facilities, underground ducts and pipelines. Compressive strength rises from 5 MPa after 24 hours to 20 MPa after 7 days and 30 MPa after 28 days; bond to the substrate from 1.5 MPa, workability is retained for 60 minutes, frost resistance at least 300 cycles.
