INTOSANA is a product made up of hydraulic lime, metakaolin, light aggregates, siliceous aggregates, Vichy salt and special mineral additions with pozzolanic activity. These light-coloured pozzolanic materials, substantially consisting of kaolins of very fine particle size, increase the mechanical performance of the plaster and have very positive effects on its durability, preventing the development of undesired reactions between the hydraulic binders and the salt compounds that are usually present in the masonry (sulphates), or they can come from particularly aggressive exposure environments (chlorides, nitrates). INTOSANA has been specially formulated to have low water absorption values and very high water vapour breathability at the same time, in addition to a lower density compared to traditional plasters. The particular balance between breathability, absorption, mechanical performance, durability, resistance to chemical attacks, makes the use of INTOSANA particularly recommended on: buildings attacked by marine aerosol; urban environments attacked by acid rain; damp walls. INTOSANA does not contain portland cements, resins, solvents and radioemissive elements.


Approximately 15 kg/m² of INTOSANA for every centimetre of thickness to be implemented (approximately 1500 kg per cubic metre).

Use fields

Plastering and repair of internal and external masonry, brick, stone or mixed.

Preparation of supports

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".

Use method

Pour about 2/3 of the mixing water into the mixer, and gradually add INTOSANA and the water still required, continue to mix until a homogeneous lump-free mixture of the desired consistency is obtained. The mixing water indicatively necessary is equal to 16-18% by weight (4-4.5 litres per 25 kg bag).

Apply by hand, with brick trowel and plaster trowel, or with plastering machine (PFT model G4 or similar).

It is advisable to apply the plaster after application of a suitable adhesive rendering. The rendering can be realised with INTOSANA slightly more liquid than normal, or by application of the specific product UNTERSANA. They must both be applied by "spraying", and they must provide a rough, corrugated surface, designed to promote the bonding of the subsequent plaster, which must be applied no later than 2-3 days. For thicknesses in excess of 20 mm improve the anti-cracking attitude, by inserting fibreglass plaster-holding.

Warnings, precautions and Ecology

Protect fresh surfaces from direct exposure to sunlight, from the rain and wind, cure the prolonged moist hardening.
