Brush-on polyurethane moulding rubber is extremely versatile and easy to use for vertical applications like walls, unusual shapes, and ceilings – such as architecture or artwork reproductions.
Smooth-On Polyurethane moulding rubbers cure with negligible shrinkage, so your mould always produces an accurate result and capture the tiniest details from textured surfaces.
For concrete stamping pads or hard plaster, it doesn’t get much better than flexible polyurethane rubber for creating your moulds.
- Available in a wide range of hardness options
- Easy to mix – often with 1:1 ratio
- No vacuum degassing needed
- Brush-on or pourable options available to meet the needs of unique projects
- Perfect for casting pigmented or coloured concrete or plaster
