High-performance water-repellent for porous materials
ImperGuard® is a high performance water-repellent product for protecting porous walls, facades and roofs from humidity. ImperGuard® penetrates deeply into the pores of the material to make it impermeable and so prevent the harmful effects of humidity: infiltrations, acid rain, erosion, freeze/thaw cycle, moss and lichen growth, efflorescence, saltpetre, etc.
The chemical composition of the solution also enables it to perform as well as a solvent-phase product. The water-repellent properties of ImperGuard® are therefore developed very quickly (within a few hours to 3 days). 
ImperGuard® also has an anti-dusting action and hardens the surface of materials.
ImperGuard® is a penetrating, non-film-forming product. The substrate remains permeable to air and water vapour. Completely colourless after application, it modifies neither the appearance nor the nature of the treated material. In addition, it is completely resistant to UV light and does not yellow with age.
  • ImperGuard® can be used indoors and out on vertical surfaces and roofs.It is ideal for the water-repellent treatment of porous materials such as natural stone, concrete, rendering, brick, terra-cotta, cement...
  • ImperGuard® is used for new works or refurbishment.
  • Excellent water-repellent properties. 
  • Quick and long-lasting efficiency (> 5 years).
  • Prevents penetration by water.
  • Limits the development of efflorescence.
  • Limits moss and lichen growth.
  • Prevents frost/thaw damage.
  • Anti-dusting action.
  • Non-film-forming – allows substrate to breathe.
  • UV-resistant – does not yellow.
  • Invisible after drying.
  • Ready and easy to use.
  • Non corrosive and non flammable.


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

Clean tools and equipment immediately after use with water.
Apply the product to a surface that is clean, dust-free, grease-free and dry. To remove stains and marks of pollution use Guard Cleaner® Polluted Facades or Guard Wash®. For efflorescence, laitance or concrete bloom use Guard Remover® Eco Efflorescence & Cement.
  • Use neat, do not dilute.
  • Shake the product well before use. Always carry out a preliminary test.
  • The treated surface should be impregnated to saturation point, either in one application or in two applications ‘wet-on-wet’.
  • Always apply from bottom to top.
  • Do not overcharge the substrate – remove all excess before it dries. Risk of white stains in case of excess.
  • Protected drying: 24 hours.
  • Maximum effectiveness achieved after 2 to 3 days.

1, 5 and 20 L can.

  • Keep in a dry place (between 5°C and 30°C).
  • Storage: 24 months following the production date when kept in the original unopened container.
Environment-friendly product:
  •   Petroleum solvent free.
  •   Safe and non toxic.
  •   Biodegradable > 90%* at 28 days.
  •   VOC < 1 g/l*.
  • Surfaces should not be treated until they have first been cleaned of all atmospheric pollution and all stains.
  • Always carry out a test first to check product’s penetration and to ensure the finished result is acceptable.
  • Do not apply to low-porous, organic, metallic or waterproof materials.
  • Do not apply to tiles in slate, or to tiles that are already treted with a protection product.
  • For ideal application and effective protection, ImperGuard® must be stirred. Also, it is essential that it be used only when the substrate temperature is between 5°C and 30°C.
  • Do not apply in rain or very hot weather. Air temperature between 5°C and 30°C.
  • Protect glass and tiled substrates, as well as wood and light alloys (aluminium, chrome, copper, zinc, etc.). In the case of accidental splashes, rinse immediately with water.
  • Do not dilute or mix with another product.
  • Respiratory protection: Under normal conditions of use where adequate ventilation is available, no special respiratory protection equipment is needed.
  • Hand protection: Wear latex gloves.
  • Skin protection: No special protective clothing or skin protection is required under normal conditions of use.
