Chemical release agent suitable for mould and shutter faces prior to casting concrete in order to archive a clean release.
DESCRIPTION
Chemical release agent suitable for mould and shutter faces prior to casting concrete in order to archive a clean release. After removal of the formwork, the resultant concrete has a smooth hand uniform finish, with reduced incidence of blow holes. Groil can be applied to the formwork by spray in the form of a light uniform mist coating.

APPLICATION
Apply before the first casting and there after repply immediately after stripping and cleaning the mould. Lightweight horticultural sprayers (knapsack type) are ideal as groil is finely atomised to give a uniform coating. Excessive application should be avoided. If after the first application, the groil is completely absorbed into new timber or plywood, a further application should be made before filling the moulds or formwork. Coat form liberally before storing to keep rust free to return forms to service sweep down and recoat with groil. Groil 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
