Flexible molding with new technologies for recreating the past

Architectural molding is the art of manufacturing construction elements that resemble high value materials, such as stone or marble, using concrete or gypsum. Single stones or entire facades can be replicated simply by casting a concrete formulation into a silicone mold. This means that architects and art restorers can recreate a multitude of "faux stones", from antique to rusticated and patinated stones, realistically and cost-effectively.

The Bluesil™​​ RTV-2 range has been specifically designed to replicate stones and other construction materials, producing outstanding fidelity for every detail, including veins and surface texture. The various grades of architectural molding silicones enable builders to replicate accurately the look while providing excellent resistance against casting materials.

  • Ease of processing

  • Resin resistant increasing the number of castings

  • Low linear shrinkage for greater accuracy

  • Easy release of shapes, including for large pieces

  • High compatibility with water-rich casting materials such as gypsum

  • Increased compatibility with high performance concrete.
