Rapid Setting Cement - Rapidcas N20

Rapid Setting Cement - Rapidcas N20 is a special formulated sand/cement mix which is easy to use and trowel and designed to set hard in about 60 minutes. Rapidcas N20 is satisfactory for even the most arduous conditions e.g. open to traffic within 2 hours. It has good bonding strength especially when used in conjunction with a polymer primer which can also be used to advantage as a 10% addition to the mixing water.
