AcraTex AntiCarbonation Coatings

barrier protection for masonry substrates

The Dulux AcraTex range of Elastomeric AntiCarbonation coatings are designed to extend the service life of steel reinforced concrete by restricting the damaging passage of carbon dioxide. Left unchecked, the infusion of Carbon dioxide from atmospheric pollutants pacifies the alkaline nature of concrete leaving embedded rebar susceptible to corrosion and ultimately concrete spalling where the expansion from within due to the corrosion by-products literally blows the concrete apart.

AS4548 : Long Life Coatings for Masonry identifies levels of performance for the protection of reinforced concrete from Carbonation as defined by research first published by Klopher in Germany in 1978.

DULUX AcraTex 955 AcraShield

Elastomeric weatherproofing & anti-carbonation barrier coating. Specified as a topcoat elevating Texture System performance or as a stand alone AntiCabonation coating for steel reinforced concrete.

DULUX AcraTex 955 AcraShield is a mid-build, Elastomeric performance coating applied by conventional nap roller or airless spray to form a finishing barrier coat in AcraTex Texture and Anti-carbonation systems. Available in Matt and Low Gloss finishes across the full Dulux World of Colour range, AcraShield delivers a paint like appearance with film builds twice that of standard decorative paint for enhanced crack bridging performance. AcraTex Texture Systems are specified with AcraShield weather-proofing topcoat for optimum life cycle efficiency.

DULUX AcraTex 968 Elastomeric 201

Enhanced Rehology, Elastomeric weatherproofing & anti-carbonation barrier coating. Specified as a topcoat elevating Texture System performance or as a stand alone AntiCabonation coating for steel reinforced concrete

DULUX AcraTex Elastomeric 201 is an enhanced mid-build, Elastomeric performance coating applied by conventional nap roller delivering minimal roller stipple for even coverage and superior weather proofing and Anti-carbonation properties Available in Matt only across the Dulux World of Colour range, pastel, deep and ultradeep colour range Elastomeric 201 delivers a paint like appearance with film builds 2-3 times standard decorative paint for enhanced crack bridging performance

DULUX AcraTex 953 Membrane 105

Ultimate Elastomeric HIGH BUILD, 500-1000 micron Airless Spray applied, performance coating specified where maximum resistance to Dynamic Crack movement and Weather proofing is required.

Dulux AcraTex 953 Membrane 105 is formulated for optimal Tensile Strength and Elongation through a full climatic range to maximise crackbridging and dirt pickup performance at low and high temperature. Specified in 800-1000 micron dry film build specifications. Tintable across Dulux World of Colour pastel and deep colour selections, Membrane 105 is deigned for airless spray application producing a smooth paint like appearance at 20-40 times standard decorative paint thickness for enhanced crack bridging performance

CARBONATION ...is the conversion ( DUE TO INGRESS OF CO2 ) of naturally high alkaline concrete conditions. In a high alkaline environment the corrossion process is deactivated & embedded steel is naturally preserved
