Description
Armourcoat Istria is a natural lime and marble polished plaster with a honed stone appearance. It is a superfine matte finish with non-directional surface movement and tonal variation.
The lime putty based plaster is water vapour-permeable and as such is suitable for traditional plastered masonry, including historic buildings.
It comes unsealed as standard. For added protection against soiling, specify with soap sealer.
It is also available to be used as a system with Armourcoat® AntiCrack reinforced gypsum skim coat. Please see specification data for more details.
