GECO LIME plaster

PREMIXED PLASTER FOR HIGH-THICKNESS APPLICATIONS ON DAMP WALLS

GECO LIME plaster is a pre-mixed rehabilitation plaster (EN 998-1 R) based on NHL 5 natural hydraulic lime, designed for damp walls and historic buildings. It is waterproof yet breathable: moisture can leave the wall while liquid water is kept out, with a capillary rise below 5 mm.

Mineral fibres improve impact resistance, anti-sagging additives give a uniform surface and controlled shrinkage minimises cracks. It goes on at 6 to 20 mm per coat – thicker builds in successive coats 24 h apart – and also levels uneven substrates with height differences up to 20 mm.

Lime makes it compatible with old and delicate substrates – stone, brick, terracotta, existing plasters – for durable restoration of existing and historic buildings.
