It extends mold life, works with most liquid rubber and plastic casting materials, and features a clear, non-staining formula. Ideal for professional mold makers seeking reliable, mess-free results—just avoid use with silicone molds. ## Description Product description Universal Mold Release Agent is formulated especially for mold making and casting, and works well with most liquid rubber and liquid plastic products. It will release mold rubbers (such as polyurethanes and polysulfides) from properly prepared models. Sealing porous models (wood, plaster, concrete) or certain modeling clays (containing water or sulfur) with Smooth-On SuperSeal or other sealer (such as spray shellac) may be necessary. Universal Mold Release is effective over a broad temperature range from 70°F to 500°F. If using silicone rubber, seal model surface with SuperSea only. Do not use Universal Mold Release. Universal Mold Release also easily releases a variety of casting materials (epoxies, Smooth-On liquid plastics, etc.) from cured rubber molds. This product has a limited shelf life and should be used as soon as possible. Properly used, Universal Mold Release improves molding efficiency for a variety of casting applications and will actually lengthen the life of your production mold. CONTENTS FLAMMABLE: Keep product away from flame and all ignition sources. Use this product in a properly ventilated area with at least room size ventilation. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. Store and use material at room temperature (73°F/23°C). Apply a Sealing Agent if Necessary - Porous surfaces (concrete, plaster, etc.) often require a sealing agent followed by a release agent when releasing liquid mold making materials. Follow directions on the mold material technical bulletin before proceeding. Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question. Refer to technical bulletin for more information available at Smooth-on website . Adult Supervision Required. Keep Out of the Reach of Children. Review: Best mold release - Perfect, good sized can.

Functions perfectly, great value if you’re looking for a silicon on silicon release. ### ⭐⭐⭐⭐⭐ Great product and quality. *by D***E on January 26, 2026* Great quality, great product, works as intended. ### ⭐⭐⭐⭐⭐ Great for epoxy release *by G***R on October 1, 2024* I have a few large silicone molds for projects. I used to use epoxy tape to prevent sticking of the epoxy in the seams. I didn't think a release spray would work and didn't want to lose my project (or the mold) because of bound epoxy. I finally used this on the sides of one of the molds because the silicone surface had some scratches that might promote sticking. The spray worked so well that I only used it for the next new pour. There was essentially no sticking. The piece popped out so easily ... I'll never go back to tape for this. I recommend it strongly and will continue to buy. No complaints; great product. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/81677527-universal-mold-release-14-fluid-ounce-aerosol-can](https://www.desertcart.co.uk/products/81677527-universal-mold-release-14-fluid-ounce-aerosol-can) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-02*
