How do I prep my mold for use with EcoPoxy products?

Mold or surface preparation varies depending on your mold type. However, it is important that all molds are clean, dry and free of contaminants.

When building your own molds out of MDF, use a sheathing tape, applied to the surface prior to final construction. Once assembled, seal the edges and corners with silicone caulking. Mold release is not necessary for this type of mold.

When building your own molds out of melamine sheet, seal the edges and corners with silicone caulking and apply a mold-release paste wax to ensure easy demolding.

For HDPE molds, mold release is not necessary. However, using a mold release is good practice to extend the life of your mold.

Silicone molds are less durable. Using epoxy will degrade the surface of the silicone mold over time. We recommend using a spray on mold release, applied to the manufacturer’s specifications. Test the compatibility of your release product with the epoxy prior to starting.
