Hi guys so after making a negative of your face it time to make a positive of the cast. To do this you layer up a combination of plaster and a fabric called Scrim to add more strength. So let’s get started .
Cup of water
Cheap medium size paint brush
Cover the nose of the Face Cast with a flat piece and blend out the edges to make sure the plaster cannot seep out.
To fix the face cast to the board create two clay sausage shapes which will support the cast on the wooden board.This prevents the nose of the cast getting damages , and the cast rolling around .
You then need to cleaned away any make-up residue or excess oil from the inside of the cast that was left from the models face when you was casting . To do this use a paper towel and gently rub the inside of the, make sure you try to get as much off as possible as the oil repels the plaster making the next step very difficult and time consuming . Then applied Vaseline around the edges of the cast were the plaster and bandages are showing. This helps when you remove the positive from the cast at the end.
Pour a cup of water into a bowl and add a handful of plaster, sieving it into the water using your hands. Allow plaster to soak into the water before mixing to a single cream texture (when plaster starts to rest on top and looks like thick wet sand then it’s ready to mix). Use hands to mix plaster and to get rid of lumps.
Using a cheap medium size Brush layers of plaster until no green rubber is showing ( the plaster may repel due to holding any oil or makeup from the models face ).Continue to paint the plaster until a thick layer is applied and allow to dry. By painting on the layers of plaster you are able to catch they effect of the skin (eg pours, wrinkles ) this means you get an exact match of the models face . if you were to pour in the plaster there is no guarantee you would get the same effect and you risk getting air bubbles in your cast .
Once the first layer of plaster is dried (it takes around 30 minutes ), spray with some water to help the next layer of plaster adhere. Paint another layer of plaster and add four small pieces of scrim (fabric) and then add another layer of plaster on top of the scrim be careful not to create any air bubbles. The scrim is used to add strength to your cast.
After the final layer has dried use a blunt tool between the rubber and the plaster and gently remove the face cast and tidy up any scrim that may be hanging over the edge with scissors .and you have your positive 🙂
Don’t worry my nostrils don’t actually look like that its where the gaps were in the cast where so i was able to breath 🙂 i will show you how to get rid of this in the next blog post
Because i wear makeup and i have oily skin it made it very difficult to paint on the first layers of plaster , it wasn’t till the plaster started to get thicker/set that it started adhering . so if i was to do this again i would make the plaster slightly thicker or let it stand for a few minute before i started to use it . Or to make it easier i wouldn’t wear makeup in the first palace if i know i was to do it again . i would of also covered the nostrils better as when i took the positive out there was a lot of plaster i had to clean away before i could use it .
