Description
Armourcoat Leatherstone is a natural lime and marble polished plaster that combines the look of lightly polished stone with the surface interest of aged leather. It is a partially honed, non-directional finish with an open texture and distinctive surface movement.
The lime plaster is water vapour-permeable and as such is suitable for traditional plastered masonry, including historic buildings.
It comes with Eco Wax applied as standard for increased protection against soiling. For breathable water repellency, specify with Armoursil Impregnator + Aquawax.
It is also available to be used as a system with Armourcoat® AntiCrack reinforced gypsum skim coat. Please see specification data for more details.
