How to Use Mold-Dit

Our Mold-Dit is formulated from a proprietary blend of food-grade waxes to be the perfect partner for your food safe moldmaking. It can be used as a non-toxic sealant on porous objects, a release agent to help prevent silicone from bonding to itself in multi-part molds, and a temporary adhesive to prevent your objects from floating in your silicone.

Using Mold-Dit to anchor your objects

Mold-Dit Being Applied to the Under Side of an Original Object to be Molded.

Step 1

Apply a 1/16" film of Mold-Dit to the bottom of your object.

Step 2

Press the object down onto your work surface so the excess Mold-Dit is forced out on all sides.

Step 3

Wipe away the excess Mold-Dit with a soft cloth or a dry, firm-bristled brush. Your object is now ready for molding.

Silicone Mold Comparison Showing How Mold-DIt Seals Objects for Better Silicone Mold Results

In each of these images, the mold on the left was made using Mold-Dit, while the mold on the right was made without. Notice that the opening of the left mold is clean, square-cornered and has no "flashing" - the thin seepage of silicone which has found its way underneath the object.

The image on the left shows a CopyFlex mold made using Mold-Dit to anchor the object, preventing it from floating in the liquid silicone. For the mold on the right the object was not anchored, and so it has floated to the top and become trapped in the CopyFlex.

Using Mold-Dit to seal porous objects

Mold-Dit Paste Consistency

Step 1

Soften the Mold-Dit using a natural-bristle artist's brush by swirling the brush over the surface of the Mold-Dit.

Step 2

Apply a generous coating of Mold-Dit to your object, using the brush bristles to work the Mold-Dit into the porous surface and cover it completely.

Step 3

Wipe excess Mold-Dit off of your object to restore the details so they can be captured by the silicone. Removing the excess Mold-Dit will not diminish its effectiveness.

Mold-Dit Seals Porous Materials Like Wood to Prevent Mold Making Silicone From Imbedding Itself in the Surface

The images above show the difference between making a mold with a sealed object and an unsealed object. The sealed object has been molded perfectly, capturing all the details. The unsealed object has been ruined, along with its mold, due to the silicone becoming trapped in the porous surface.

Using Mold-Dit as a release agent

Applying Mold-Dit as a Release Agent to a Silicone Mold Flange

Step 1

Apply a thin layer of Mold-Dit to completely coat the mating surface of your two-part mold. Don't forget to coat the alignment keys, too!

Step 2

Make the second half of your mold and allow it to fully cure.

Step 3

Once the silicone has cured, the Mold-Dit will enable you to easily pull apart both halves of your mold with no sticking. This works with both CopyFlex and Silicone Plastique.
