FX 526 is used in interiors and exteriors as a filling primer-undercoat that, thanks to its hiding power and levelling
properties, creates a coloured, uniform surface. It is used on lime and lime-cement finish coat and skim coat plasters
and renders before applying water-based coatings, such as RAR 256, RTA 549, RSR 421, RX 561, FASSIL R 336,
and water-based paints. The fine aggregate used improves anchoring of the finish both on external thermal insulation composite systems and on already painted masonry substrates.
FX 526 comes in 14ltr tubs.
