Profskrin RC50 RTi — ultra-rapid-hardening thixotropic R4 mortar with fibre
Non-shrink thixotropic R4 mortar to EN 1504 with polymer fibre: 20 MPa in compression after 2 hours, work at temperatures from −10 to +35 °C.

The non-sparking filler is the main difference between FC807 and other LEVELINE toppings: the surface does not spark under impact, so the mix is used at sites with explosion and fire safety requirements. The technology is the usual one for a dry-shake topping — application onto fresh concrete and floating, and the manufacturer recommends the non-sparking screed FC806 as the base. Compressive strength at 28 days is at least 70 MPa, abrasion class AR1, service from −60 to +200 °C.
