Bond Breaker

Allcon offers same-day dispatch Australia-wide for most stocked items, including bond breakers. Customers can also arrange convenient call-and-collect orders directly from our Melbourne or Sydney warehouses that operate from 6.30am - 4.30pm Mon-Fri. Orders placed after 4.30pm (AEST) can be collected next-business day after 7.30am.

Although both are designed to prevent concrete from sticking, a bond breaker is used specifically for tilt-up and precast applications, where one cured surface must be separated from a fresh pour. A form release agent, by contrast, is applied to formwork to allow easy removal of moulds after the concrete sets.

Using a concrete bond breaker ensures clean panel separation, reduces surface blemishes and minimises damage during lift-off. It also helps maintain dimensional accuracy in precast components, improving overall construction quality.

Not all projects require a bond breaker. They are typically used in tilt-up panels, precast elements and similar applications where two concrete surfaces come into contact. For standard vertical pours using formwork, a release agent may be more appropriate.

Always follow the manufacturer’s guidelines. Generally, the bond breaker should be applied evenly with a low-pressure sprayer on a clean, dry surface. Multiple coats may be needed depending on environmental conditions and surface porosity.

Bond breakers are not suitable for all formwork materials. They are typically designed for use on sealed or dense surfaces such as steel or smooth-faced casting beds. For porous timber or other absorbent materials, use a form release agent designed for that specific application.

No, a properly applied bond breaker for concrete will not compromise the concrete’s structural strength. It acts only as a surface treatment to prevent adhesion and does not interfere with the curing or composition of the concrete mix.

Yes, most bond breakers are formulated for horizontal use, such as tilt-up slabs or casting beds. However, some specialised products may also be suitable for limited vertical applications. Always consult the product data sheet to ensure the bond breaker is appropriate for the surface orientation and pour design

The right bond breaker depends on your construction method, surface type and environmental conditions. For tilt-up or precast work, ensure you select a concrete bond breaker compatible with the form surface and curing requirements.
