This is one of our most popular coaster molds! Basic Coaster Mold 893 is made of durable, smooth, reusable polypropylene and measures about 3 1/2” in diameter. It holds about 3 ounces of resin when completely filled. Some buffing and/or sanding may be needed on the finished piece to achieve a smooth surface. The deep side of the mold can be used to make coasters and similar castings but turn the mold over to its shallow side and you can use the same mold for a round holiday ornament or a dazzling suncatcher!
How to Use Resin Molds: Remove any dust and particles from your reusable mold. Molds do not require mold release when casting with resin, however, it is strongly suggested. We recommend the use of Castin' Craft Mold Release and Conditioner. Protect your work area with freezer or wax paper. Treat mold with mold release and allow to dry. Place mold on a level surface and fill the cavities to just below the top. Once the pieces are cured, turn the tray over and press the center area of each piece while flexing to release the casting. Do not use sharp objects to demold your resin as you will scratch your mold. Be sure to also read our plastic resin mold care tips to ensure a long life for your molds.
