Stumped about how to finish a silicone rubber cast when regular paints and dyes seem to fail? The answer lies in the specialized formulation of silicone paints that flawlessly adhere to the rubber surface.

Silicone rubber is a specialized material that is popular with both mold makers and casting artists. The rubber is versatile and durable, and therefore, finds varied usage in the world of arts.

The only major problem with silicone rubbers is that they cannot be painted on with regular paints. Indeed, using acrylic or other paints on a silicone cast will cause them to crack, chip and peel off within no time. And casting artists simply abhor having to leave the silicone rubber cast with an unfinished look!

This is where silicone paints come to the rescue!

What is Silicone Paint?

Silicone paints and dyes are specialized products that have the ability to become chemically incorporated into the silicone casting rubber. Therefore, the paint is durable and flexible. Any amount of bending or twisting will not cause the paint to chip or break away. In addition to this, it proves to be resistant to heat, chemicals, UV light and other external conditions.

The paints are available in a variety of colors and shades.

How to use?

The silicone dye is a two-part system. It has to be mixed with the medium to form the paint. The latter will cause it to cure and harden.

Before use, the silicone cast should be cleaned and dried properly. The mixture can then be painted on the silicone surface with a brush, sprayed with an air gun or the entire cast can be dipped into the paint.

Alternatively, there is another option to mix the dye in the silicone rubber material itself (prior to the casting) to give it a uniform intrinsic effect. Some casting artists even opt to paint the interior of the mold cavity (with a brush or spray gun). It is allowed to cure before pouring the silicone rubber to create the final casting as desired.

The same silicone paint is also used in the film and television industry to create special effects and prosthetics.Airbrushing and layering can create a very realistic effect for films and theatre productions.

Always keep in mind that the silicone dye should be properly mixed with the medium (in tune with the manufacturer’s instructions) to get the best results.

In sum, silicone paint is ideal for finishing a silicone cast. It works well with other metals and plastics too. The paint will adhere well and deliver a smooth and glossy finish.
