RC CALCOFIN 100
ultra-fine lime finishing plaster for smooth, breathable mineral surfaces
RC CALCOFIN 100 is an ultra-fine mineral finishing plaster based on natural hydraulic lime NHL 3.5 from Saint-Astier. It is designed as a high-performance skim coat for applications requiring a perfectly smooth, even and highly breathable finish. With an extremely fine aggregate size of 0–0.1 mm, it combines refined aesthetics with the technical benefits of a lime-based, cement-free system.
It is ideal for restoration, renovation and high-end construction projects where vapour-permeable building systems are required.
Applications of RC CALCOFIN 100
RC CALCOFIN 100 is used as a fine finishing layer on mineral substrates such as lime renders and cement-free mortars. It is particularly suited for heritage restoration, renovation works and ecological construction where moisture regulation and breathability are essential.
The plaster provides an excellent base for lime paints, silicate paints and siloxane coatings, delivering a smooth, mineral and uniform surface finish.
