Looking for an effective formwork release agent? In this article, we review some of the most popular release agents from renowned manufacturers – Shole and Ekobet. Find out how they work, what properties they offer, and which product is best suited to your construction site.

What are formwork release agents and how do they work?

Formwork release agents are products that create a thin protective layer on the surface of moulds and formwork, preventing concrete, asphalt or resins from sticking. They make formwork stripping easier, protect surfaces from damage, reduce mould cleaning time and lower equipment maintenance costs.

Types of formwork release agents – which one should you choose?

Various concrete release agents are available on the market, including:

• Liquid release agents
• Release oils
• Release emulsions

Products can also be classified according to how they work:

• Barrier release agents – create a physical layer between the concrete and the mould.
• Barrier-chemical release agents – additionally neutralise the chemical action of concrete.
• Chemical release agents – actively react during concrete setting to help achieve a smooth surface.

How to apply a formwork release agent: a comparison of methods

• Spraying – high efficiency, even coverage and reduced product consumption.
• Brush or roller application – good precision, but higher consumption and a greater risk of uneven coverage.
• Immersion – suitable for serial production of precast concrete elements.

Spray application can achieve coverage of up to 60 m² per litre, particularly with Shole and Ekobet products.
