Decontamination and purification of external air
  • DtoxGuard® Ext is a colourless treatment for porous outdoor substrates. It cleans the air by breaking down pollution (nitrogen oxides - NOx) by photocatalysis.
  • DtoxGuard® Ext also destroys organic grime and dirt. Treated surfaces are then rinsed by rain and therefore stay clean longer.
  • DtoxGuard® Ext penetrates the substrate without forming a film, so the substrate remains permeable to air and water vapour. Colourless, the product does not alter the nature of the treated substrate. It is also totally UV-resistant and does not yellow with time.
DtoxGuard® Ext is for exterior use on all vertical porous surfaces (walls, facades and roofs) such as renders, concrete, mortar, glass reinforced concrete, terracotta, non polished stone, slate, roof shingle, non mineral substrate.
  • Breaks down organic grime and cleans the air.
  • Easy to clean.
  • Non-film forming - allows substrate to breathe.
  • UV-resistant, non-yellowing.
  • Ready to use and easy to apply.
Apply with a brush, roller or a low-pressure spray gun.

Clean tools and equipment after use with water.
  • Apply the product to a surface that is clean, dustfree, grease-free and dry. To remove stains and marks of pollution use Guard Cleaner® Polluted facades. For efflorescence, laitance or concrete bloom use Guard Remover® Eco Efflorescence & Cement.
  • Conditions of application and substrate preparation must comply with French unified code of practice DTU 59.1.
  • Use product neat - do not dilute.
  • Shake container well before use. Test first.
  • The substrate must be applied in 2 to 3 coats. Time between coats: 20 min (at 20°C).
  • Apply from bottom up.
  • Avoid applying too thickly. Remove any excess before drying with a dry roller.
  • Protect for 24 hours from rain and 48h from stains.
  • Optimal performance after 7 days.
  • Physical state at 20°C: Liquid
  • Colour: Milky
  • Odour: None
  • pH: 11.3 ± 0.2
  • Boiling point [°C]: 100°C
  • Relative density: 1.03 ± 0.02
  • Solubility in water [vol/vol]: Total
  • Flashpoint [°C]: Not applicable
Coverage depends on how porous the material is. The following value is for guidance only: 7 to 10 m2/litre.
1, 5 and 25 litres.
  • Keep in a dry place (between 5°C and 30°C).
  • Storage: 12 months following the production date when kept in the original unopened container.
Environmentally friendly and ecological:
  • Water-based product.
  • No petroleum-based solvents.
  • Safe and non-toxic.
  • VOCs < 1.5 g/l*.
  • Always clean off all atmospheric pollution and all stains from the surface before applying the product.
  • Do not apply on glass and glass surfaces (risk of tampering, protect these surfaces well).
  • DtoxGuard® Ext must be stirred first. It is also essential to use it when the temperature of the substrates is between 10°C and 30°C.
  • Do not apply during rain or in very hot weather. Air temperature: between 10°C and 30°C.
  • Hygrometry rate should be between 20% and 80%.
  • Moisture of the surface should be less than 5% and less than 14% for wood.
  • Do not dilute or mix with another product.
  • White marks may appear on some surfaces, and if too much product is applied. Always test on a small area first to check appearance. Remove all excess before drying.
  • Respiratory protection: Wear an ABEK P3 mask.
  • Hand protection: Wear latex gloves.
  • Skin protection: Wear protective clothing.
  • Eye protection: If there is a real risk of splashing, wear protective goggles.
  • If swallowed: Do not induce vomiting. Contact a doctor or a specialist.
KEEP OUT OF THE REACH OF CHILDREN
Reduction of NOx emissions:
Test of reduction of NOx is carried out by the LMDC laboratory (Laboratoire Matériaux et Durabilité des Constructions) on a normalized concrete according to the standard ISO 22197.
Polluted gas containing up to 400 ppb of NO is injected in the reactor. Light is then switched on. Several lights are tested: fluo UV, fluo visible, halogen, LED with different intensities. Pollution is calculated at the exit of the reactor thanks to an analyzer which detects residual NO, NO2 produced and NOX. The efficiency of the product is characterized by the reduction of NO. Decrease from 38% to 72% can be observed.

Self-cleaning test:
Self cleaning test is carried out in real conditions by the LMDC laboratory (Laboratoire Matériaux et Durabilité des Constructions). 
One part of the material is treated with DtoxGuard® Ext, the other part remains untreated. Tested soot. Samples are left outdoors. Results are observed after 90 days.

Other tests:
Chemical nature
A mixture of inorganic binder and photoactive tita-nium dioxide.
