Types and benefits of formwork release agents

Releasing agents mean coatings which are provided on the formwork surface, before starting of concreting to allow smooth detachment of the form work or shuttering. Consideration should be given on the finish surface of the shuttering as it reveals all the flaws on the ‘form’ surface like vibrating poker known as ‘burns’, changeable properties in the form-face material, marks of irregular water absorption in timber.

Prior to pour the concrete, loose wire & debris should be cleansed with a compressed air hose. Make sure that steel particles are eliminated since it will create erosion & manipulate the final finish of the concrete.
