Microporous anti-crackling base for walls and vertical surfaces

Code: PRT.0170

Components: 1

Appearance: Liquid

Anti-crackling base, based on siliceous aggregates of different particle sizes, potassium silicate, nylon microfibre and specific agents, in a special mix ensuring watertightness, water-repellence, permeability to steam. Available in two different particle sizes, on request. Specific for the reclamation of internal and external vertical surfaces, characterised by significant presence of cracklings from shrinkage (also of width up to 1 mm), for homogenising regularisation in general. It can also be used as a base to obtain a rustic effect of the finish. Particularly suitable for the anti-cracking reclamation of historic buildings.

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.


Apply from 0.30 to 0.50 kg of SANAXIL FILLER per square metre of surface to be treated.

Use fields

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.

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).

Use method

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.

Application methods

- Paint roller

- Spatula

Tool cleaning

- Water

Permitted supports

- Cement-based or lime-based mortars

Warnings, precautions and Ecology

During application, protect glass, enamelled metal, aluminium, polished tiles etc., which may be opacified from accidental contact with silicate solutions.

Avoid application in the presence of rainfall and high humidity.

Depending on the temperature conditions at the time of application, and during the drying and dessication phases, colours may vary slightly.
