Marbocote Mould Sealer is a high-performance polymeric resin in an organic solvent blend, designed to seal micro-porosity and fill minor scratches on mould surfaces. It enhances gloss and provides a smooth base for subsequent Marbocote release agents. Ideal for use on new or repaired GRP, vinyl ester, epoxy, or metal moulds, it ensures a durable, non-transferable release and minimal mould build-up.
