Applying and colouring SFX silicone prosthetic pieces


Coat the back of the prosthetic with prosaide or similar and then coat the skin area where it's to be applied. You only require a thin layer of adhesive. Ensure the glue is dry before gently applying. If a mistake is made, use 99% alcohol to deactivate the glue and then reapply.

When applying prosaide or fake-up adhesive, make sure it isn't too thick. The adhesive is dry when clear. If you apply too much, it will take much longer to dry. If you can see white spots, it isn't dry and will not stick.

If you are applying a silicone piece that isn't encapsulated in cap plastic, such as our silicone nipples, move to step 3.



Melt away the cap plastic edges with acetone, gently wiping outwards with a cotton bud or soft brush. 

Some parts of the acetone may be thicker than others and will require additional blending. The outer silicone ring is a throwaway part.

If the encapsulated cap plastic is too thick, it may take long to melt it and blend the edges. We supply our prosthetics with a thin layer so it's easier to blend.


Colour the piece with alcohol activated paints. Use darker colours to add depth and yellows/oranges for the fatty tissue.

Darker colours like black, can help to increase the look of depth, making the wound look like it's deeper into the skin.

Only use darker colours on the central area of the wound. To blend the skin tone, use washes of colour, preferably using alcohol activated paints. Remember not to concentrate on just the silicone prosthetic and work on the skin area around it as well.

You can also colour with cream paints, but this might not work as well as AA paints.


Use a stipple brush to flick red colours over the prosthetic and the skin to blend the piece. You can also dab colours to blend it in, however light washes are better and will have a nice effect.

Some people like to add a bruise effect, which can also help blend the piece into the skin, however for realism, don't forget that you rarely get bruising with an open wound.


Add some blood!

Stippling the blood works well, but it's up to you what effect you want to achieve. 

You can use various types of fake blood including silicone flow, clotted and drying blood.

The fake up adhesive kits are normally sent with silicone flow blood, which doesn't bead on the appliance or skin. And of course, blood is totally optional, especially if it's an old wound that doesn't require any at all.
