How to Clean Concrete Casting Moulds

  • Use a thin layer of release agent to cover your whole mould when preparing for casting. This makes cleaning your moulds afterwards much easier and stops the concrete sticking to your mould.
  • Use a general purpose cleaner to wash off any residue left on your mould and spray off with a high pressure sprayer or hose.
  • Your mould is now ready to be prepared for next casting.
