  • Vapour permeable.
  • Improves resistance to frost and external penetration by salts.


  • All surfaces to be treated should be clean, dry and free of paint, oils or other contaminants such as moss or lichens.
  • Poor mortar joints and large cracks should be made good and allowed to dry before treating.
  • Fine hairline cracks are unimportant.
  • Sika Water Repel is ready to use.
