Sika® Separol® RL 225

Water based chemical release agent

Sika® Separol® RL 225 is a chemically active, ready to use release agent blended with water. Sika® Separol® RL 225 is applied to mould and shutter faces prior to casting concrete in order to achieve a clean release. After removal of the formwork, the resultant concrete has a smooth, hard, uniform finish, with reduced incidence of blow holes. Sika® Separol® RL 225 can be applied to the formwork by spray in the form of a light uniform mist coating. Suitable for use in hot and tropical climatic conditions.  

  • Easy and precise separation of the formwork from the hardened concrete
  • High quality surface finish
  • No reduction of the concrete quality at the surface
  • Protection of formwork from steel corrosion and early ageing

Consumption

30 – 40 m2/l  when spray applied depending on smoothness and porosity of the formwork used.

Coverage is considerably enhanced on marine ply and steel faced forms.

 
Application steps

APPLICATION

Apply before the first casting and thereafter re-apply immediately after stripping and cleaning the mould.


Lightweight horticultural sprayers are ideal as Sika® Separol® RL 225 is finely atomised to give a uniform coating. Excessive application should be avoided.


Alternatively, application may be made by a fine haired brush, only a very thin coating should be made and any excess removed.


If after the first application, the Sika® Separol® RL 225 is completely absorbed into new timber or plywood, a further application should be made before filling the moulds or formwork.

 

CLEANING OF EQUIPMENT

Sika® Separol® RL 225 may usually be left in spray guns or sprayers without detriment, but with certain types, there may be some softening of rubber seals with prolonged contact.
