DULUX AcraTex Acrasilane IBTES
DULUX AcraTex 964 AcraSilane IBTES in a non film-forming, deep penetrating surface treatment that chemically bonds within the masonry pore structure to create a permanent hydrophibic layer on and below the surface of bare concrete and other mineral based porous surfaces.
Typically used in structural grade installations where as a concrete pretreatment under AntiCarbonation Coating systems providing ultimate and last line defense against the ingress of water soluble chloride ions which other wise may accelerate re-bar corrosion.
- Repels water, Chlorides
- Invisible film
- Penetrates deeply into dense concrete
- Treatment becomes part of the concrete
and cannot peel
- Minimises dampness in porous surfaces & protects against moisture
- No change in the appearance of masonry
- Apply direct to bare masonry.
- In beds itself as part of the structure
|Weatherability||] Protects masonry for up to 3 years.|
|Heat Resistance||] Resistant to normal exterior surface
|Water Resistance||] Excellent resistance to rain and condensation
for prolonged periods|
|Abrasion Resistance||] Moderate resistance to abrasion|
|Solvent Resistance||] Resists alcohols & hydrocarbons|

Use and typical specification
Use DULUX AcraTex 964 AcraSilane IBTES to reduce water and chloride absorption on unpainted concrete . DULUX AcraTex 964 AcraSilane IBTES penetrates into the pores and forms an invisible protective film. Dependant on the porosity of the substrate / specification multiple saturation coats may be required. Recommended on reinforced concrete structures such as low and high-rise buildings, wharves, concrete bridges, car parks and sound barriers.
Typical properties and application data
||DULUX AcraTex 964 AcraSilane IBTES is applied to the surface by saturation using a hand pressure spray
applicator or HPLC spray equipment . The product should be applied as a stream which runs down the wall approximately
10 - 20 cm. A second application should follow 1-2 hours after the first application.
The object is to saturate the surface so that the product can penetrate as far as possible into the surface. For full details refer to individual Duspec Product and AcraTex Applicational Data Sheets. |
