Over time, it has also proven to be a highly effective general-purpose release agent delivering reliable performance across various applications. For outdoor precasting operations, AS88 is the ideal choice. It is commonly used for precast wall panels, kerb stones and similar elements cast in steel pans particularly where production is exposed to external conditions.

It is especially effective in operations where pipes are steam cured at high temperatures, ensuring clean release without compromising surface quality.
Where stack casting is required or when an effective bond breaker is needed AS666 delivers outstanding results.

Similarly, for decorative and architectural concrete items that feature fine detail, Supercast provides excellent surface release and finish making it well suited to intricate moulds.
A.Shak Construction also offers specialised solutions such as AS333 and 3B Grease which are used for pipe ends, coffers or applications where a highly durable release agent is required. For cost-sensitive production environments AS118 is a cost-effective emulsion widely used in the pipe industry where steam curing is not part of the production process.
