    Sanaxil Filler

    Due to its mineral nature and the chemical adhesion it provides, Sanaxil Filler represents a significant revolution in the traditional concepts of adhesion to supports: it penetrates deeply into the pores, it reacts with the components of the masonry structure creating a homogeneous, indissoluble and breathable "silicated" whole; it does not form films, it is water repellent and resistant to moulds and micro-organisms. When it is applied in combination with paints or putty coats, it substantially improves their durability, because it gives a greater thickness to coatings and paints.

    Sanaxil Filler is composed of stabilised potassium silicate, silica aggregates and natural pigments. It has high breathability, excellent mildewcide and antibacterial properties. It has no solvents, thinners, harmful substances in general.

    Fields of application
    Subbase micro-smoothing, for subsequent coatings with paint or with putty coat, specific for the anti-crackling reclamation of large vertical surfaces of buildings and condominiums in general. It creates of a thick base to improve the durability of the coating.
    Allowed supports
    Cement-based or lime-based mortars
    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".

    It is recommended that you preliminarily treat the media with the specific fixative Sanaxil Fix (as such, or diluted with water up to a ratio 1:1).

    Mode of use
    Sanaxil Filler should only be used for reclamation and under the conditions described above. It can be applied with a roller or brush, possibly after dilution with 10-15% Sanaxil Fix.
