Architectural Reproduction & Restoration

Brush-On Rubber for Architectural RestorationArchitectural Reproduction and Restoration specialists use Polytek liquid mold rubbers to make site molds of aging/damaged ornate architectural elements (e.g., brackets, panels, cornice moulding, statuary). From these molds, reproductions of damaged elements can be cast in the controlled environment of a mold shop. These imperfect castings are resculpted to their original beauty so a rubber production mold can be made from this revised model. This production mold allows repeated casting of the new architectural element in concrete, glass fiber reinforced concrete, plaster, plastic, fiberglass, or other casting media as required for interior or exterior mounting.

Polytek®'s room-temperature curing polyurethane and silicone rubbers are popular mold materials for this application and are available in pourable, brushable and sprayable options.

Casting materials, including rigid polyurethane foams, flexible casting plastics and rigid casting plastic are also available from Polytek® for casting finished architectural elements.
