Jesmonite Flex Metal Gelcoats are premium, rapid-setting acrylic polymer-modified cement composites formulated with real metal powders to deliver strikingly authentic metallic finishes. Designed for professional makers, artists and fabricators, these innovative gelcoats provide the look and feel of solid metal without the weight, cost or safety concerns associated with traditional metallic coatings.
Engineered as a safer and more environmentally considerate alternative to conventional systems, Jesmonite Flex Metal Gelcoats are alkali-free, shrinkage-compensated and highly durable. Their low-permeability formulation ensures excellent resistance to external weathering, making them suitable for both interior and exterior applications. Unlike Portland cement-based materials, they are free from efflorescence, ensuring a clean, consistent surface finish over time.
The gelcoats are intended to be used purely as a decorative facing layer and must be backed with compatible Jesmonite composites, including AC630, AC730 or AC830, with or without glass fibre reinforcement. They can be brushed, pasted or trowelled into moulds, allowing fine detail capture and excellent surface definition. Once cured, the surface can be burnished with wire wool to reveal and enhance the metallic sheen, producing a convincing bronze, brass or copper effect.
Mixing Ratios (Base-To-Liquid):
Available in three distinctive metallic colours, Jesmonite Flex Metal Gelcoats offer flexibility across a wide range of creative and commercial projects. Project-specific technical advice is available by calling 01752 658498.
