RonaBond Anti-carbonation Coating WB

A smooth, creamy water based acrylic coating. It is used as a protective and decorative coating for new, maintenance and refurbishment work and can be applied to most traditional building surfaces including concrete, repair mortar, render and masonry after preparation.

It provides a weather resistant surface which resists the ingress of CO2 and allows the substrate to 'breathe'. When applying RonaBond Crack Bridging Anti-carbonation Coating WB to facades, RonaBond Anti-carbonation Coating WB should be used for soffits and below DPC level, to reduce the risk of blistering associated with elastomeric coatings applied to substrates containing high levels of moisture. The semi-thick nature of RonaBond Anti-carbonation Coating WB provides high opacity.

  • Excellent vapour permeability.
  • Permanent flexibility.
  • Water based - environmentally friendly.
  • Large standard colour range.
