The product
The high-traffic member of the range: a two-component polymeric microcement with a mineral appearance and a compressive class of C80. Specified for garages, warehouses, galleries, stores and corridors, in four grain sizes suitable for both floors and walls.
Where it is used
- Continuous coating for interior floors and walls
- High-traffic areas such as garages and warehouses
- Galleries, stores, waiting rooms, corridors and offices
Substrates
- Concrete with minimum 25 N/mm² compressive strength and minimum 1.5 N/mm² pull-off
- Ceramic substrates mechanically roughened to guarantee adhesion
- Dry, clean and free of dust, grease or dirt
- Previous varnish or paint fully removed
Application data
Coverage, thickness, mix and cure, as declared by the manufacturer. Site conditions in the Gulf sit at the top of most of these ranges — allow for it in the programme.

Where not to use it
The limits are as much a part of the specification as the performance. Everything here is stated on the manufacturer's data sheet.
- Cannot be placed on underfloor heating
- Sensitive to vinegar and other organic acids
- Contains silica — respiratory protection required when sanding
- Performance figures marked 1* are measured without sealer
Microcement: Cemher Microrock two-component polymeric microcement in colour [ref] and grain [Fine / Medium / Base / Thick Base], applied over a substrate of not less than 25 N/mm² compressive strength and 1.5 N/mm² pull-off. Compressive strength Class C80 to UNI EN 13892-2:2005, adhesion Class B 6.0 to UNI EN 13892-8:2003. Not to be laid over underfloor heating. Sealed to the sealer specification.
