Sika® Release Oil

ready to use formwork release agent

A ready to use formwork release agent 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. Apply undiluted by spray, brush or roller ensuring a thin and even coverage. Care should be taken to avoid over application which can result in dusting of the concrete surface. Any excess material in the bottom of the moulds should be mopped up prior to the placement of the concrete. For new and unsealed timbers or other highly absorbent formwork, pre-treatment is recommended with a second coat prior to use. After application, an evaporation period of 20 minutes (at +20°C) should be observed prior to casting.
