Size: 1kg
Sale price


Jesmonite AC730 Flex Liquids are supplied as an alternative to standard AC730 Liquids to create laminates with increased flexibility. The Flex liquids are also ideal when Jesmonite AC730 is used as a coating for Polystyrene for external sculpture - the increased flexibility reduces the likelihood of cracks forming in the coating due to moisture build-up and thermal movement. Flex Liquids are designed to work in a number of ways. They act as a curing membrane to ensure that the cement component of AC730 Base hydrates fully, thus reaching full strength and durability. They also provide a degree of extra ductility due to the flexible and highly water-resistant pure acrylic resin used. Additional benefits are reduced porosity and increased frost resistance.


Glass-reinforced decorative architectural mouldings, and small castings. Glass reinforcements such as Jesmonite Quadaxial Fabric or 13mm Glass Chopped Strands are recommended for lightweight, high-impact panels. It can also be used to create garden ornaments and statuary and is suitable for water features.
