Guard Hardener® W

High-performance surface hardener and water-repellent

Guard Hardener® W is a mineralisation product for new or old brittle porous materials damaged by water ingress, damp, ice, etc.

Guard Hardener® W penetrates brittle materials in order to crystallise, harden and mineralise. Once treated, the material becomes harder and resistant to harmful external factors. It can also be used as an anti-dust treatment.

Guard Hardener® W possesses excellent water-repellent properties which enable the adverse effects of damp to be limited: ingress, acid rain, erosion, ice/de-icing cycle, formation of moss and lichens, efflorescence, saltpeter formation, etc.

Guard Hardener® W is a non-film forming impregnation product, the material remains permeable to air and water vapour. Completely colourless after application, it does not change the appearance or the nature of the treated material. It is also fully resistant to UV rays and does not yellow over time.

Surface preparation :

  • 1
    Apply the product to a clean surface.
  • 2
    Depending on the brittleness of the material, clean manually using a brush or chemical.

Application :

  • Use the product in its pure form, do not dilute.
  • Shake the packaging well before use and perform a preliminary test to check that the product has correctly penetrated and the appearance after drying.
  • The material must be impregnated up to saturation in a single coat or two coats “wet on wet” depending on the porosity.
  • Do not overload the material, remove any excess before drying. Risk of white marks.
  • Optimum efficiency reached after 2 to 7 days of drying.
  • The treated material cannot be covered by another coating.

For further information, refer to the data sheet and safety sheet.

  • Apply using a low-pressure sprayer, roller or brush.
