Sika® Release Oil

Ready to use formwork release agent

A ready to use formwork release agent which can be applied by spray, brush or roller. Suitable for mould and shutter faces prior to casting concrete in order to achieve a clean release after removal of formwork. The resultant concrete has a smooth uniform finish with reduced incidence of blow holes.

  • Excellent ‘sticking’ ability on vertical mould surfaces.
  • Self-levelling after spray application.
  • Non-combustible vapour.
  • Reduced ‘dusty’ residues on the formwork.
  • Safe for the operatives to handle.
  • Easy and precise separation of the formwork from the hardened concrete.
  • High quality surface finish.
  • Protection of formwork from steel corrosion and early aging.

Application steps

APPLICATION

  • All formwork should be clean and dry before application, with any residues of rust or concrete removed. Stir thoroughly before application.
  • Before casting, apply a thin and uniform film of Sika® Release Oil to the clean, dry formwork or mould, ensuring that the entire area is covered. This can be done by brush, but a finely atomised spray coating is the best method.  Any excess should be removed prior to casting the concrete.
  • Once the formwork or mould has been removed, immediately clean and reapply Sika® Release Oil.
  • Pretreatment with a second coat prior to use is recommended on new and unsealed timber.
  • After application, an evaporation period of 20 minutes (at +20 °C) should be observed prior to casting.
