Saint-Astier ECOMORTAR R100

ECOMORTAR® R100 is a cement-free, lime-based preparation and resurfacing plaster designed for internal and external applications. Formulated with Saint-Astier hydraulic lime, fine sand and specific additives, it provides a strong bond on low-absorption substrates, making it ideal for renovation and refurbishment projects.

R100 is suitable for a wide range of backgrounds, including waterproofed and painted surfaces, metal, masonry, terracotta, ceramic tiles, plasterboard, drywall and cement renders. It provides a fine base plaster for smooth finishes and can be used to homogenise and resurface different substrates.
