Description
Armourcoat Koncrete Honed is a natural lime and marble polished plaster that offers a refined take on the raw concrete aesthetic of contemporary architecture. It is mid-sheen finish with fine surface texture, subtle tonal variation and non-directional patternation.
The lime plaster is water vapour-permeable and as such is suitable for traditional plastered masonry, including historic buildings.
It comes with a natural soap sealer 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.
