Innolayn NC40 RF3 — R4 grout for work at −25…−10 °C
Cementitious R4 grout for installing equipment, columns, joints and anchors at sub-zero temperatures; 15 MPa after 6 hours at −25 °C.

When fine finishing of concrete has to be done in winter, Profskrin RC40 FSm is used: a finishing mortar designed for temperatures from −10 to +10 °C. It is suitable for load-bearing and bridge structures, treatment and industrial facilities, underground ducts and pipelines. Its strength values are the same as those of Profskrin RC40 Sm: from 20 MPa in compression after 24 hours, 30 MPa after 7 days and 40 MPa after 28 days, and the mix stays workable for 30 minutes.
