Silicone paint-primer with quartz filler Farbex

Silicone paint-primer Farbex


Silicone paint-primer

with quartz filler



It hardens the base surface. It has high level of adhesion, high vapor permeability and low water permeability. It makes application and structuring of silicone and acrylic decorative texture products easier. It is resistant to the effects of water, frost, precipitations and sunlight.

Sphere of application

It is intended for preliminary coating with the purpose to harden the surface and improve adhesion, and also to make application of silicone and acrylic waterborne products (structured paints, decorative stuccos, etc.) easier. It is intended for interior and exterior works. It can be applied on any mineral (concrete, brick, plaster, putty, gypsum) and wooden surfaces (ply wood, MDF, wood chip boards, OSB). It can be used with facade insulation systems, as well for building conservation for winter period and also as separate decorative coating.


It can be tinted manually with Pigment Concentrate Farbex Color, other waterborne coloring pastes or with a coloring machine acc. to NCS color range and others.

Application instruction


1. Preliminary preparation

Uncoated surfaces: Clean of fragile surfaces till hard base surface, dust, oil, grease and other dirt.

Fresh coats of the stucco shall not be treated 2-4 weeks.

Previously coated surfaces: Clean thoroughly the surface from old loose coats (peeled paint or varnish) in a mechanical (a scraper, a wire brush), thermal (a hot air dryer, infrared radiation) or chemical (paint removal solutions) way. Clean the surface from all kinds of dirt. Surfaces previously coated with alkyd or oil enamels shall be sandpapered. Then treat the surface as the uncoated one.

Non-significant defects of mineral surfaces shall be corrected with Finishing Putty TM Farbex. Then sandpaper the surface.

Treat the surface with Antiseptic product TM Farbex to protect against mould and fungi.

2. Priming

Previously treated mineral and wooden surfaces need no undercoating.

Previously untreated absorbing mineral surfaces shall be undercoated with a deep-penetrating silicone primer TM Farbex.

Previously untreated wooden surfaces shall be undercoated with wood-protective acrylic primer TM Maxima.

3. Applying

Stir thoroughly the products before use. The paint primer is ready to use and needs no dilution. The application shall be performed at the temperature of air and the surface from + 5 °С till + 35 °С and relative air humidity less than 80%.

Do not apply the paint under direct sunlight, strong wind, frost and precipitation. The surface shall not be affected with precipitation or sub-zero temperatures for 24 hours after the coating is applied.

Subsequent works shall be performed in 24 hours.

4. Tool cleaning

Clean tools with water after application. Do not let them dry. The dry product shall be removed from the tools in a mechanical way.


Flow calculator

Consumption standard of 1 layer

When calculating the area to be painted, you need to subtract the area that will not be painted. (windows, doors, etc.)

Paint consumption may vary depending on dilution and uniformity of application of the paint.
