Silkolitt+ Silicone Renders

Silkolitt+ silicone renders provide a lightweight, contemporary finish to building facades, whether used as part of an External Wall Insulation (EWI) system or in render only applications. Silkolitt+ contains high quality silicone binders and mineral aggregates that underpins the strong hydrophobicity and flexibility of the render.

Silkolitt+ is available in a range of colours and textures to provide the desired finish:

  • Choice of 8 standard colours, contact us for other options
  • UV resistant colour pigments
  • Choice of 3 grain sizes – 1.5 mm, 2.0 mm or 3.0 mm – to offer a range of textural finishes

Key Features

Silkolitt+ is one of our high performance ready to use silicone renders – lightweight, textured and offers the following benefits:

  • High water and dirt repellency that protects the façade against freeze-thaw failure & fungal growth
  • Excellent vapour permeability that allows the building to breath and prevents interstitial condensation
  • High tensile adhesion strength that prevents delamination and flaking
  • Good flexibility providing resistance against cracking and increasing durability
  • Rated as Class ‘0’ for surface spread of flame when used in EWI systems

Used in conjunction with:

  • Alumasc Facades by K Rend Silicone Primer
  • Alumasc Facades by K Rend Façade Protector
