Argatherm is a lime-based skim coat with thermal mineral fillers, for walls and ceilings inside and out. It trowels to a semi-smooth finish that smooths a Diathonite wall for paint while keeping it breathable, and its microporous fillers add insulating value of their own (λ 0.128 W/mK). Applied 2–10 mm total in 1.5 mm passes; overcoat with Argatherm Ultrafine where a fully smooth surface is wanted.
