    Sanatrock SA

    It is a mix of a high action dehumidifier, ready to use, only mix with water with a NHL natural hydraulic lime base, Botticino, kaolin, silicate and lime aggregates, mineral fibres and specific agents. It is a mix , together with the adequate inert substances, that enables plaster to be created with high breathability, free of cement, resins or solvents and radio-emitting agents, in compliance with bio-architectural parameters
    Fields of application
    Breathable dehumidifying plaster on the walls (on adding aggregates).
    Allowed supports
    Bricks
    Mixed walls (bricks and stones)
    Brickworks
    Stone walls
    Preparation of supports
    Prepare the surface to plaster by removing, if present, the existing plaster, up to a height over approx. 50/100 cm compared to the line of persistent damp. The walls for application should in any case be clean, intact, free of containment, dust, flaking or inconsistent parts, conveniently saturated with water (saturated to dry surfaces). In the presence of saline efflorescence, accurately remove it and give a preventive treatment with a spray application of Sanareg. Then, a subsequent preliminary construction of a rough coat with breathable grip, with the specifically prepared Untersana, or "spraying" (here and there) the same mix as described below.
    Mode of use
    Prepare the plaster by firstly placing in the mixer approx. 2/3 water for the necessary mix, and then respectively adding Sanatrock SA and clean, select sand with the desired granulometry (you are advised to use sand with a maximum diameter of up to 2-3 mm). For packaging in the warehouse, comply with the following use instructions:
    - kg15 Sanatrock SA
    - kg 35-40 sand with a max granulomety 2-3 mm.
    - litres 12-13 of water (the quantity of water can decrease according to the humidity in the sand used).
    During preparation of the mix, pay attention and add the useful amount of water to obtain an even and creamy mix with the weight/litre of approx 1.3 – 1.5 Kg. This objective is however very easy to reach with minimum attention to the useful mixing time.
    On the wall, previously make adequate “level stops” (strips are recommended using mortar obtained or wooden boards adequately placed in position and to plumb).
    Apply the product with a trowel with a total thickness of approx 2-3 cm. Do not carry out any finishing, smoothing or crushing operation with the trowel or the blade of the mortar applied. Strike the “level stops” leaving the surface rough and leave to harden as is. Skim and finish the following day, possibly with the specific Sanastof dehumidifying coat or definitively with a skim coat with a breathability index (μ) under 11.


    Normally for a building site cement mixer with 200 litres, you are advised to initially add 100 kg of Sanatrock SA, 225 kg of sand and 45 litres of water. During mixing, add water to the mix until you reach the desired consistency (based on the humidity rate of the sand used you may need more or less litres of water). The water normally necessary in the mix is around 16-18% in weight compared to the total weight of the mix (Sanatrock SA + sand). Continue to mix until you obtain an even mix free of lumps. With a 25 kg bag of Sanatrock SA you can normally plaster 3.5 m² of wall at 2 cm thick.

    Apply the mix obtained using a trowel or plastering machine. Finish with skimming systems that are definitely breathable, such as Sanastof.
