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.
Where new and existing concrete and masonry structures require protection from Water, Carbon Dioxide, Sulphur Dioxide, Oxides of Nitrogen, Chlorides, Sulphates and UV radiation.
Examples: Car Parks, Commercial and Industrial Buildings, Bridges, Subways, High rise flats. This is a one time solution for domestic properties. Should be compatible to most existing masonry paint coatings.

Reprotec Wonderwall may be applied at a nominal rate of 5m²/litre/coat. The recommended two coat treatment will provide an overall d.f.t of 200 microns, which is the minimum for long term anti-carbonation properties.
Do not apply at temperatures of 3°C or less or if there is a risk of frost.
