Universally applicable, silicone resin facade paint based on SilaCryl® with mineral characteristics. Highly diffusion-capable and water-repellent.

Field of Application

For high-quality exterior coatings on smooth and textured substrates. The SilaCryl® base provides excellent moisture proofing, high water vapour permeability and sufficient CO2 permeability.
In addition it provides for the same colour diversity, weather resistance, chalking stability and adhesive strength as high-quality pure acrylic based paints.

On roughly textured renders Muresko provides texture preservation or texture equalisation, depending on the degree of dilution. Particularly suitable for the renovation of stable existing coats on AAC (autoclaved aerated concrete)/cellular concrete prefab parts.

Material Properties

  • Water-dilutable, ecologically compatible, low odour.
  • Weather-resistant.
  • Water-repellent according to German standard DIN 4108.
  • Alkali-resistant, hence unsaponifiable.
  • Easy to apply.
  • Excellent covering of edges.
  • This product is provided with an encapsulated preservative against deterioration in the coating film due to algal and fungal attack.

Material Base / Vehicle

Silicone resin + pure acrylate dispersion/emulsion.

Muresko is tintable with CaparolColor or AmphiColor® (AVA) colourants. If more than one bucket is manually tinted, all product must be thoroughly mixed before use in order to avoid colour differences.
Quantities of 100 litres or more in individual colours can be ordered ready-tinted ex factory.
Muresko can be tinted to all current colour collections via the ColorExpress tinting & mixing machine system. Check tinted product before applying in order to avoid colour differences. Always use tinted paint of same batch, when applying on seamless surfaces.
When colour shades with a lower opacity (hiding power) are used, e.g. red, orange or yellow, it is advisable to apply a prime coat (undercoat) of Muresko or CapaGrund Universal, tinted in a matching priming system colour, available via ColorExpress. Possibly a second finishing coat may be necessary.
