STOPROTEC Transparent Coating for Concrete and Block Substrates

Weather-proofing technology for masonry surfaces differs to that of thick paint systems for achieving weather-tightness. Because exposed masonry is designed to be seen, STO weather-proofing technology treats the block itself so that it becomes water resistant above and below the surface, a clear transparent skin is then applied over the top.

The STO Transparent Coating System compromises of two flood coat applications of a penetrating silane sealer (Protectosil WS405) with a further three applications of a single pack clear coat. The Silane is applied wet on wet, as once dry it will repel itself. As the Silane penetrates below the surface it starts to close up the capilleries inside the block. To achieve best results this process needs five days for a full catalysis reaction. The Stoprotec is then applied in three coats. Once it has cured, it provides a durable and breathable coating with excellent UV stability and elastomeric qualites which comes in a matte or low sheen finish.
