Silane siloxane based penetrative protective coating


Polyxane is a single component highly penetrating protective treatment for concrete, masonry and stone work which works by penetrating into the pores of concrete, masonry, stone work and reacts with moisture or water vapour that is present in the substrate thus forming a hydrophobic siloxane lining to the capillary pores. This hydrophobic treatment is very effective in reducing the passage of water and water borne salts whilst allowing moisture vapour to dissipate to the atmosphere. Polyxane is also used as a primer for anti carbonation coatings.


  • Highly penetrative clear, non-staining sealer
  • No change in surface appearance/texture
  • Integral protection, cannot delaminate or degrade
  • Reduces discoloration of white or coloured concrete due to pollution
  • Reduces the ingress of Chloride ions and Sulphates
  • Excellent water repellant characteristics
  • Compatible with solvented surface coatings

Step by Step

Surface Preparation

All surfaces to be treated should be fully cured, dry and free from laitance, traces of mould oil or curing compounds. Oil, grease and previous coatings must be removed completely. If the surface to be treated is washed after cleaning it must be allowed to dry before the application of Polyxane.


Polyxane may be used directly from the container. No dilution with water or solvent is required, however the contents of the container should be mixed before use. Apply by a low-pressure spray or brush ensuring complete coverage. on vertical surfaces apply flood coats starting at the bottom of the panel and working upwards. A min of two coats is required; which should be applied, ‘wet on wet’. A maximum of 2 hours over coating time is permissible. typical consumption will and be 4-5m²/l per coat. However, site trial is recommended to ascertain the exact coverage. High winds are detrimental to even application and will increase wastage. Erect wind breaks if required. Polyxane is solvent based adequate ventilation is required. Also care is to be taken to avoid prolonged contact with air as it reacts with atmospheric humidity.
