Urethane products are created by first spraying the inside of the mould with a barrier coat of primer. Liquid urethane is then poured into the mould, which is quickly shut and sealed. The urethane expands, hardens, and fuses with the coat of primer. The mould is then unlocked and opened, revealing a perfect duplicate of the original product, complete with a finished coat of primer.
