The 24x16x2" silicone mold is mold for woodworkers looking to create larger than usual wood and resin boards. This BIG mold allows you to create large three square foot resin works, or small 24x16" table tops up to 2" thick.
This mold can be used with various types of resin, concrete, and even mixed media such as a combination of live edge wood and resin.
Important: This is a rough form mold. It will have minor surface imperfections such as deviations in finish from glossy to matte, as well as variations in surface height (mostly along the sides) of up to 1/16". Unlike our discounted Grade B molds where the imperfection unintentionally happened in production of the silicone mold, the rough form molds, such as this one, have imperfections strictly due to the imperfections in the tooling (the master form / blank that we use to create the silicone mold).
This mold being an odd, low volume size, was created with low cost tooling (layered plywood, sanded then flood coated in resin) to reduce the cost of the final silicone mold. Thus, you should expect a certain level of post-processing (sanding and/or flood coating) after you remove your piece from this mold. If you are using this with wood and resin, these imperfections make no difference as you need to plane, trim and sand your piece anyway. However resin artists should not expect a perfect piece right out of this mold like they would our other silicone molds.
Crafted Elements Silicone Molds
The last mold you will ever need. Created just for makers, resin artists and wood workers, these time saving flexible yet durable silicone molds significantly cut down on the setup and demolding time usually involved with other molds. Silicone molds are superior to wood and tuck tape, and HDPE molds because:
They can be used with epoxy resin, resin and wood, concrete, Jesmonite, plaster and more.
They never need assembled, or disassembled. Saving huge amounts of time.
The strength and flexibility of the molds allows you to insert and remove pieces of wood easily.
The corners and edges never need sealed.
When using wood, the wood stays in place, tight in the mold if you cut it 1/16" larger than the width of the mold. Preventing the need for clamps or weights.
The mold is heat resistant to ~450F. Avoid direct contact with the flame of a torch. Briskly wave your torch or use a heat gun to pop bubbles.
The molds are reusable. However silicone molds do have a finite lifespan when used with epoxy resin, but getting 20-30+ castings out of the mold can be expected when they are properly cared for and a non-silicone based mold release spray is used.
Like HDPE, epoxy resin does not stick to silicone. However, the heat generated by the exothermic reaction and the chemicals in epoxy resin are very harsh to all silicone molds. Additionally, if part of your epoxy has not fully set due to improper mixing, the epoxy can become bonded to the mold. Both of these factors can lead to mold tear out when removing your piece from the mold, leading to pits and tears on the surface of the mold. This is why we a non-silicone based mold release spray is required before each pour. To help prevent tear out and to increase the life of your mold. We use the 'MG Chemicals 8329 Non-Silicone Epoxy Mold Release', 'Smooth-On Ease Release 200', 'Mann Ease Release 200' or 'Mann Ease Release 300' which are readily available from Amazon and other online retailers. Cooking spray, vaseline, silicone based sprays or sprays designed for urethane or polyester products should NEVER be used. Using a proper, non-silicone based mold release can mean the difference between getting only a couple of uses from your mold to 20, 30 or more.
