Two-component PU faux stone (culture stone) casting material — reproduces natural stone & wood texture. Shore A ≥80, moulded density 250 kg/m³, ~95% closed-cell, self-adhesive, flame-retardant. Casts decorative siding, cornices, frames & carved furniture.
Our two-component PU faux stone (culture stone) casting material is a high-density polyurethane system that faithfully reproduces the texture of natural stone and wood. With a simple 1:1 mixing ratio, ~95% closed-cell structure and excellent self-adhesion to wood, metal, brick and glass, it casts lightweight, durable, weatherproof decorative elements — from stone siding and cornices to picture frames and carved furniture — with crisp, repeatable mould detail.
Decorative building materials — faux stone siding, cornices and mouldings, decorative wall panels, picture & mirror frames, carved furniture and artware, European-classical furniture parts, ceiling medallions, shoe moulds and large carving products.

Prepare the mould
Use a silicone or hard mould with the desired stone/wood texture; condition materials to ~20 °C.
Mix
Combine premixed polyol and MDI at 100:100 (1:1 by weight); stir 10–15 s, by machine or by hand.
Pour
Cast into the mould — cream 30–60 s, gel 75–150 s, tack-free 100–210 s.
Demould & finish
