With the addition of mixing water only, this single-component premix creates a breathable, dehumidifying rough coating, preparatory to the application of restorative, dehumidifying, thermal-insulating and anti-condensation plasters, specifically INTOSANA, SANATIGH, SANAWARME and CALEOSANA, being plasters designed specifically for the healthiness of new buildings, existing buildings, works on green buildings and in the restoration of historic and monumental buildings.

UNTERSANA is composed of hydraulic lime, botticino, kaolin, calcium caseinate, Vichy salt, tartaric acid and natural fibres. Does not contain cements, resins, solvents, thinners and radioemissive aggregates.
From 4 to 6 kg of UNTERSANA per square metre of surface to be rendered.
Anchoring scratch coat (applied by "spraying" or "splashing") for the formation of an adhesive bridge for easy grip of subsequent plasters, dehumidifying, breathable, based on hydraulic lime.
Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface".
Pour about 2/3 of the mixing water into the mixer, add UNTERSANA and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 22-25% of the weight of the bag. After mixing is completed wait a few minutes before applying.
"Spray" the product, with plastic fluid consistency, on the application supports, with plastering trowel and brick trowel or with plastering pump. Protect fresh surfaces from direct exposure to sunlight, from the rain and wind, cure the prolonged moist hardening.

- Finishing trowel
- Plastering machine
- Mixed walls (bricks and stones)
- Stone walls
For a proper adhesion of the next plaster, it is appropriate to apply the latter before the complete curing of the rendering UNTERSANA (within 24-36 hours).
