DULUX AcraTex AcraShield Advance 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 Advance 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 Advance weather-proofing topcoat for optimum weatherability.

Features

  • Elastomeric Membrane
  • Carbonation Protection
  • Barrier against dirt resistance
  • Selection of Dulux UV resistant full colour range

Benefits

  • Protective finishing coat in AcraTex systems. Flexible, crack bridging ,elongation performance to maintain barrier protection
  • Protection from reo-bar corrosion of steel reinforced concrete
  • Improves surface washability and reduces dirt accumulation

Product code: 194X0100
