Sylitol® Minera

Silicate-based, quartz-filled priming and finishing coat for exterior and interior use – as per DIN 18363, section 2.4.1.

Field of Application

Suitable for filling, texture levelling and crack filling coatings, for exterior and interior use. Applicable as priming, intermediate or finishing coat.

Sylitol® Minera is perfectly suitable for adhesion promoting priming coats on surfaces on which coatings have been etched away by paint stripper. Highly suitable as priming coat before applying silicate-based coatings. Sylitol® Minera can also be used for filling small joints or surface defects and fine cracks in renders/plasters, before the application of Sylitol®  paints and renders/plasters.

Sylitol® Minera is particularly suitable as fine textured intermediate coating in interiors before applying creative silicate translucent glazing/scumbling coat techniques. Sylitol® Minera is suitable for protective coatings on AAC wall panels and complies with the requirements of AAC manufacturers.

Caparol interior thermal insulation systems:
Suitable for use on Capatect IDS Aktiv and Capatect IDS Mineral.

Material Base / Vehicle

Potassium silicate (waterglass) with organic additives, according to DIN 18 363, section 2.4.1

Packaging/Package Size

Standard Product: 8 kg, 22 kg


White. Tintable to a max. of 10 % with Histolith-Volltonfarben (colourants).
The desired texture and filling power cannot be obtained, if a higher amount of colourants is added.
If more than one bucket is manually tinted, all product must be thoroughly mixed before use in order to avoid colour differences. Quantities of 200 kg or more in individual colours may be ordered ready-tinted ex factory.

Sylitol® Minera can be tinted to all current colour collections via the ColorExpress tinting & mixing machine system, in light colours up to luminosity/lightness index (LI) approx. 70. Check tinted product before applying to avoid colour differences. Always use tinted product of same batch, when applying on seamless surfaces.
For AAC coatings the LI (reflection factor) should be above 40.
Brilliant, intensive colours may have a lower opacity (hiding/covering power). It is therefore advisable to apply a first coat in a similar hiding pastel tint, based on white. Possibly a second finishing coat may be necessary.
