    MasterFinish RL 309

    Solvent-free form release agent for precast elements with aesthetic surfaces 

    Where good surface finish and optimum release are a prerequisite, using a form release agent is essential. MasterFinish RL 309 P is a solvent-free form release agent based on highly refined mineral oils and biodegradable additives, specially formulated to provide easy, complete release of the concrete from precast forms. It significantly improves the concrete surface's quality for a smooth, homogeneous finish without pinholes.

    Where to use MasterFinish RL 309?

    MasterFinish RL 309 is supplied ready to use and can be applied on all types of absorbent and non-absorbent concrete forms, such as wood, metal, phenolic and silicone moulds. MasterFinish RL 309 can also be used for steam curing. It can be applied by spray, brush or roller on any type of form.

    What makes MasterFinish RL 309 different?

    MasterFinish RL 309 improves the concrete’s exposed surface economically by reducing application time and allowing quicker stripping, easier and faster cleaning of the forms, contributing to longer lasting formwork. Its low viscosity ensures easy and economical application.

    Solvent-free MasterFinish RL 309 is safe and eliminates many of the health and environmental risks associated with traditional form release agents containing solvents, meaning that precast workers can use it with maximum confidence.

    Whether normal or delayed stripping is needed, MasterFinish RL 309 provides steel forms with better protection against rusting.
