Painting on Silicone Casts

 Finishing silicone casts with paint is a challenging task as regular paints tend to crack or chip off very soon. EnvironMolds brings a special dye and paint system that will easily incorporate into the silicone.

Silicone rubber is a versatile material that is used to make both molds and casts to suit different applications. It is easy to use – just mix in the required quantity of base and catalyst in the prescribed ratios and you are ready to go. Moreover, as silicone does not stick to anything but itself, the mold making and casting process is relatively straightforward and effortless. The rubber can be specially formulated to be food or even skin safe, thus lending itself well for making food and body molds.

However, the problem arises when the artist tries to paint on a silicone cast. Indeed, you may feel like finishing the cast with a beautiful color of choice, however, regular paints will start cracking, chipping and wear away with time.

Alas, the smooth finish and waterproof qualities of the silicone weighs against it in this regard. Even if you use oil-based paints for their better adherence, the inherently flexible nature of the rubber will cause the paint to wear off easily.

At times, people try making the silicone surface rough by soaking it in denatured alcohol or rubbing it with sandpaper. While this can work for regular silicone caulking, the coarse facade will end up marring the silicone cast and render it unpleasant to the eye.

It is only special silicone paint and dye that can adhere to the silicone rubber and yield the desired finish. EnvironMolds ( offers the special Cirius silicone formulation for painting and dyeing silicone creations. The silicone base of the dye comes to the rescue here as silicone will definitely stick to itself! Try bending and twisting the silicone rubber cast as much as you wish – but the color will not crack, peel or even rub off as it has become chemically incorporated into the silicone!

How to use?

You can mix a few drops of the silicone dye with the base before adding the catalyst to give an intrinsic uniform hue during the casting process itself. Swirling one or two drops of dye in the mix can also create a lovely marbled effect in the silicone cast.

On the other hand, there is also the option of diluting the dye with a silicone medium for coloring after the cast is ready. It can then be painted, sprayed or air brushed on the silicone surface to get the desired finish. However, it is important that the cast should be cleaned and prepped properly prior to painting. The brushes should also be cleaned quickly after use.

This silicone paint is considered compatible with both tin and platinum cure silicone variants. However, the dye can interfere with the setting of platinum silicones.

Twelve different hues are available, including the famous ‘Quinn Blush' used by renowned doll rebirthing artist Terry Quinn to add skin blush to her silicone dolls.
