Description

Acrotel EC-A Elastomeric Anti-Carbonation Protective Coating is a single-component, liquid-applied elastomeric, high-build acrylic protective coating. It is designed to protect concrete structures against moisture intrusion and carbon dioxide diffusion, preventing the carbonation of concrete and risk of corrosion of the reinforcing steel.

Advantages
  • Resistant to carbon dioxide diffusion.
  • Low VOCs, meeting LEED Green Building Rating System Credit 4.1.
  • Low odour, non-toxic.
  • Breathable water-resistant barrier.
  • Resistant to ultraviolet radiation and weathering.
  • Low Tg, long lasting, and capable of bridging hairline cracks at low and high temperatures.
  • Excellent dirt pick-up resistance.
  • Excellent colour retention.
  • Skins over in 30 minutes, and tack free in 2-4 hours.
  • Easy to apply, easy to clean.
Uses

Acrotel EC-A Elastomeric Anti-Carbonation Protective Coating is used as a protective waterproof coating in vertical and horizontal applications over exterior above-grade walls, including concrete, brick, masonry, stucco, EIFS, stone, pre-cast, and exposed aggregate surfaces. Acrotel EC-A Elastomeric Anti-Carbonation Protective Coating will bridge hairline cracks throughout a wide range of temperatures.

Coverage

Coverage per coat (minimum of 2 coats required):

  • 2.5 m2 / L (100 ft2 / gal) @ 16 mils WFT (8 mils DFT)
  • 4 m2 / L (160 ft2 / gal) @ 10 mils WFT (5 mils DFT)

Coverage rate will vary according to the porosity and roughness of the surface being coated. Very rough or porous surfaces may require more than two coats to provide the required minimum 10 mils dry film thickness
