Description
Armourcoat Pitted is a natural lime and marble polished plaster with the appearance of lightly polished limestone. It is a partially honed finish with a subtle, non-directional open texture.
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.
