Application

  • Preventing wind-driven rain ingress to north facing or exposed elevations.
  • Preventing moisture getting to insulation within cavity walls.
  • Lime rendered walls.
  • Water repellent treatment of walls and exposed brickwork, natural stone or non-glazed ceramic.
  • Improving the thermal performance of all wall types.

Description

A transparent, colourless wall coating, water and siloxane-based, ideal to protect porous walls of various substrates from wind-driven rain. After treatment, the wall is deeply impervious to water ingress and so better protected against frost damage. The treated wall will continue to dry and vapour drive is not effected due to the coating being very vapour permeable.


The resultant dry wall is much more thermally efficient and will save on heating bills also. Having a low molecular weight, Diasen BKK penetrates deeply into the substrate, creating an invisible but deep layer of protection that is extremely stable to lime and very permeable to water vapour.


Features and benefits:

  • DIY solution - easy, quick and cost effective to apply.
  • Very cost effective.
  • Long lasting water repellence.
  • Increased thermal efficiency of the wall.
  • Permeable to water vapour.
  • High resistance to weathering and UV.
  • Does not alter the colour of the wall finish.
  • Prevents surface efflorescence and mould.
  • Solvent-free, non-toxic and odourless.
  • Non-flammable - No volatile organic compounds (VOCs).
  • Suitable substrates include mortar, natural stone, lime render, non-glazed ceramic and concrete.
  • Life expectancy of approximately ten years.
  • Can be applied via brush, roller, or garden-type pressure spray.
  • Please note that this product is not to be diluted.
