BIRSS VRS 600 — R4 repair mix for high-strength concrete structures
Fibre-reinforced thixotropic mortar for column and beam corners, balcony edges and working joints; service temperature up to +300 °C.

A single Multipol binder yields a smooth self-levelling floor, an anti-slip coating with a quartz broadcast, and filled and wear-resistant versions. The system is used in the chemical, food and automotive industries, in covered car parks, retail halls, warehouses and museums, and also for decontaminable coatings at nuclear industry facilities, including nuclear power plants. Shore D hardness is at least 89, bond to concrete at least 3.9 N/mm².
