Silicone resin based plaster coating, supplied in paste form. For use on top of Silancolor Primer Plus.

Features and benefits:

  • Creates a rustic effect; attractive finish on interior and exterior surfaces.
  • Available in different grain sizes.
  • Suitable for use on walls where environmental conditions favour the growth of algae, mould and fungi (contains anti-mould and anti-algae agents to help prevent their formation).
  • Used to help improve wall hygiene.
  • Gives good water repellence and transpiration to the substrate.
  • Makes the substrate permeable to water vapour.
  • Good filling capacity.
  • Contains synthetic fibres for crack resistance.
  • Uniform colour tone.
  • Forms an efficient, long-lasting protection system when used in conjunction with Silancolor Primer Plus and Silancolor Cleaner Plus.
  • High adhesion onto existing paints and all types of traditional and dehumidifying renders that are well bonded to the substrate.
  • Creates a porous film, allowing the render to remain dry.
  • Protects the substrate from chemical aggression, does not show dirt easily, and is resistant to UV rays and ageing.
  • CE marked and complies with the requirements of EN 15824, 'Specifications for external renders and internal plasters based on organic binders', for internal and external use.
  • Ready to use product.


For professional use. Can be applied with a trowel. Should be mixed before use. Suitable for internal and external application. Application examples include:

  • Decoration of facades (including north facing facades in damp climates) which have been deteriorated by algae and mould, or with old paintwork.
  • Decoration of all types of cementitious and lime based render.
  • Decoration of Mape-Antique and PoroMap based renders, and dehumidifying renders.
  • Finishing coatings for cladding systems such as Mapetherm.
