Scotty's Silicone Bloodpool is a 2 part platinimum silicone that is blood coloured.

To create your own Bloodpool simply mix Part A and B in a 1A:1B ration by weight

Once fully mixed, pour over a non pourous surface in your desired patter and wait till it cures. Then peel up and enjoy your no messy cleanup blood pool. 

Always test on desired surface first. Silicone will bond to loose weave fabrics, which can be a good thing if you would like to permanently make clothing look blood soaked without sticky fake blood.

May stain some fabrics.

Working time is 8 Min with a 25 min cure time.
