Description

Steperle is a natural lime and marble polished plaster with an intricate surface texture. Inspired by a beautiful, aged Botticino marble mosaic floor in Lombardy, Steperle is a reimagining of this traditional craftsmanship as a modern wall finish. It is a superfine, mid-sheen finish with a non-directional pattern for use on interior walls.

It is water vapour-permeable and is suitable for traditional plastered masonry, including historic buildings.

It comes with Eco Pearl applied as standard for increased protection against soiling.

It is also available to be used as a system with Armourcoat® AntiCrack reinforced gypsum skim coat. Please see specification data for more details.
