Fosroc Renderoc HB25

Renderoc HB25 is a high build, shrinkage compensated concrete repair mortar for patching up to 1m2 sections in concrete up to 30 MPa. It can be applied to vertical concrete patches up to 80mm deep. Suitable for use with Galvashield anode protection systems.
Typical Applications
Vertical & overhead patch repairs
Localised trowel or wet spray application, up to 1m2 repair area, trowel build depth between 10-40mm required, and required strength
Advantages
