Fosroc Renderoc FC Polymer Modified Fairing Mortar is designed for application in thin layers to produce a fair-faced appearance to concrete surfaces or masonry surfaces in readiness to receive a protective/ decorative coating.
Surface imperfections up to 3mm in depth can be filled with the scrape coat application. Voids of greater depth should be separately filled as a prior operation, again limiting the Renderoc FC material thickness to 3mm.
Renderoc FC can be used independently to infill surface imperfections and voids or to render large sections of concrete or masonry at up to 3mm thickness. It can also be used in association with other Renderoc mortars. Under normal conditions, the product does not require an independent primer or curing membrane.
