Characteristics

OSMOSANA is based on lime and hydraulic binders, botticino, kaolin, silica aggregates, tartaric acid, different silicates and carbonates. It has no traces of resins, solvents and radioemissive aggregates.

The hydraulic reaction of OSMOSANA produced by the natural chemical combination, of water lime and kaolin (metakaolin or industrial cocciopesto (lime mortar with crushed pottery)), also called "superpozzolanic" reactivity, is comparable to the hydration reaction of cement materials, but in ecological building key.

Consumption

Approximately 1.4 kg/m² of OSMOSANA for each millimetre of thickness to be made.

Use fields

Waterproofing treatments of brick or mixed external walls, provided they are sufficiently porous and absorbent and free from any waterproofing and / or water-repellent surface treatment, whether chemical (siloxanes, epoxies, polyurethanes, etc.) or natural (wax-up), before backfilling. Anti-capillary rising damp treatments in the construction of subbase screeds.

Preparation of supports

Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., water repellent treatments in general, 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, add OSMOSANA and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. After mixing is completed wait a few minutes before applying.

Apply on site with a brush, spatula or roller, depending on the desired result. The mixing water indicatively necessary is 24-36% by weight (6-7 litres/bag for applications with the spatula, 8-9 litres/bag for applications by brush or roller).

Application methods

- Brush

- Spatula

- Low pressure airless nebulizer

Tool cleaning

- Water

Permitted supports

- Concrete

- Bricks

- Mixed walls (bricks and stones)

- Stone walls

Warnings, precautions and Ecology

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

Do not use for waterproofing works with negative hydraulic thrust.
Do not apply on little or non-porous substrates or previously coated with water-repellent treatments in general, if not after appropriate roughening by bush hammers, sanders and equipment suitable for preparatory treatments of substrates, or after appropriate treatment with suitable polymeric primers.
