Grimas stage blood comes in 3 types:
Film blood behaves like the real thing. It flows when wet and dries
realistically. It is available in two colours. Blood A is
bright red like oxygenated blood from an artery. Blood B is darker and
represents blood from a vein.
You can use instant coffee granules to darken film blood.
Blood syrup is used where you want the blood to stay looking fresh.
It dries with a shiny finish.
Blood paste is a thick paste which is
excellent for older wounds. It stays in place and is therefore less
likely to drip on clothing etc.
Stain removal
ALL stage blood will stain clothing and often leave a faint yellow mark on
pale skin. This is normal. There is no such product as
non-staining blood.
Do not try to remove skin stains by rubbing. Use makeup remover liquid to
gently lift the colour out.
Some stains in clothing can be treated by pre-soaking the fabric in Biotex or
similar. This needs to be done before the blood dries.
