Multi-size usage option:: If you are looking for a slightly smaller mold, we recommend cutting pieces of 2" thick HPDE plastic (or screwing two or three 3/4" pieces together) to create a spacer. For example, a 2x12x2" spacer will allow you to pour a 16x12x2" board in this mold.

The MAS silicone mold is an essential mold for woodworkers who combine wood and epoxy resin to create serving boards and charcuterie boards. Also great for resin art or encasing objects up to 2”.

Let’s break down why MAS Epoxies Silicone Mold is the best choice for all your resin project needs.

Save Time & Money

MAS Epoxies Silicone Mold offers a maximum savings in both time and money because they can be reused multiple times. The polyurethane silicone material is incredibly flexible which makes it easier to remove your project once cured without damaging it. This means that you can turn out multiple projects faster so you can move on to your next project. Plus, since the mold is reusable, you don’t have to buy new ones each time you embark on a new project.


Easy To Use & Clean Up

MAS Epoxies Silicone Molds make it easy for any creative person to get started with their own custom creations without having to worry about power tools, assembly or messy clean up afterwards. The silicone material is a non-stick surface, which means that epoxy resin will not adhere to the polyurethane once it has been poured into the mold and cured. This makes de-molding and clean up a breeze! Plus, since this mold can be used multiple times, there is less waste involved in making multiple projects as opposed to buying wood, tape, release agents, tools and screws every time you want to create a project!


Versatile & Durable

The 12" x 18" x 2" size of this MAS Epoxies Silicone Mold make them perfect for a variety of projects such as end tables, candle holders, charcuterie boards, jewelry trays, resin art, and so much more! They are also incredibly durable and will last through multiple uses without losing shape or form. Just make sure when making resin projects that you avoid any exothermic reaction (the resin overheating) so that the temperature of the resin does not exceed 400°F (200°C) which could cause the resin to adhere to the polyurethane.  This mold will provide years of reliable use for all types of creative projects!
