DULUX AcraTex 955 AcraShield

Code: 194-51950

Approvals: APAS-0117/3, APAS-C- 0118/3 (system approval) CONFORMS TO AS4548.1, AS4548.2 : Long Life coatings for masonry

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 Colour Specifier 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.

Features

  • Elastomeric Membrane
  • Carbonation Protection
  • Barrier against dirt resistance
  • Selection of Dulux UV resistant full colour range
  • 10 Year warranty when applied as a full Acra-Tex system

Benefits

  • Protective (barrier-shield) finishing coat in AcraTex systems. Flexible, crack bridging , elongation performance to maintain barrier protectio as substrate expands & contracts.
  • Protection from re-bar corrosion of steel reinforced concrete
  • Significantly improves surface washability and reduces dirt accumulation staying cleaner longer
  • Delivers full exterior Dulux range
  • Warranted system delivering extende life cycle & reducing maintance costs
