Reprotec Wonderwall



Elastomeric, breathable, micro-porous coating that will enhance the beauty of any structure and protect it for many years to come.

Regular price Excl. VAT: £96.00 Incl. VAT: £115.20


Reprotec Wonderwall has been formulated to confer long term protective and decorative properties to concrete and masonry surfaces.

The microporous structure of the coating acts as a barrier to the ingress of Chlorides and Carbon Dioxide and other acid gases, but allows the passage of water vapour from the substrate.

The elastomeric nature of Reprotec Wonderwall ensures good crack bridging properties, in case of structural movement.
