Retanol Approved Cement List
To achieve the best results with Retanol screed additives, PCT Chemie recommends that the following types of cement should only be used:
Type: Portland cements CEM I, or Portland composite cements CEM II (for example A-L, A-LL, B-L, B-LL). Please see the PCT Cement List for further information
Class: 32.5 N + R/42.5 N + R (note that 52.5 is less suitable for screeds due to its higher strength which can increase the risk of cracking and deformation)
Quality: Use standardized and QC-monitored cements
Only the cement type categories highlighted in green in the following cement clearance list should be used when mixing Retanol screeds.
