RB-MO Solvent based chemical release agent
Chemical release agent suitable for 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. RB-MO can be applied to the formwork by spray in the form of a light uniform mist coating.
- RB-MO is formulated for application to plywood, timber, steel and plastic faced formwork and moulds, prior to casting concrete, to ensure a clean release.
Features and benefits :
- RB-MO has no negative effect on the properties of concrete nor will it impair the adhesion of subsequent surface treatments when applied at the recommended coverage rates
- RB-MO reacts chemically with cement to impart excellent release properties to treated surfaces. Concrete cast against surfaces coated with RB-MO exhibit a smooth, hard, uniform finish
How to use :
Apply before the first casting and thereafter re-apply immediately after stripping and cleaning the mould. Lightweight horticultural sprayers are ideal as RB-MO is finely atomized 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 RB-MO is completely absorbed into new timber or plywood, a further application should be made before filling the moulds or formwork. The coverage rate for RB-MO is 30 to 70m²/liter when spray applied depending on smoothness and porosity of the formwork used.
Progressively better results are obtained on plywood and timber moulds as they become impregnated and the operatives become accustomed to working with the release agent. RB-MO in general, may be used over timber moulds. etc., which have been treated with other mould oils, providing excess has been removed.
