2 mm GRAIN: approximately 1.85 -2.15 kg/m²;
2.2 mm GRAIN: approximately 2.00 -2.30 kg/m².
The indicated yields refer to smooth supports and are for guidance only. Actual consumption must be identified with a suitable practical test.

Use fields

Restoring protective coatings based on stabilised potassium silicates, for vertical and horizontal surfaces.

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". Existing paints (washable, organic, solvent-based etc.) must be removed.

Use method

Homogenise the surfaces by applying the fixative SANAXIL FIX. Spread SANAXIL in two coats: the first, for simple deposition, with steel trowel, the second, for spreading and finishing, with sponge float. The application of the second coat must be carried out, when the first coat starts to dry, under one of two suggested conditions: with dry trowel, for smooth surfaces; with moistened trowel, for antique-effect surfaces.

SANAXIL I is dry to the touch after 4 hours, it can be overcoated after 2-5 hours, while it will be dry in-depth after 16-32 hours.

Warnings, precautions and Ecology

Do not apply on surfaces in gypsum, on surfaces that are not cured, on moist or hot surfaces, with direct solar radiation.

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

Colours may vary slightly depending on the temperature conditions at the time of spreading and during drying and dessication phases.
