Product Information

ABOUT AC630

Jesmonite DESIGN DECK (2).png
  • Can be used for applications that require greater dimensional stability, overall strength, and enhanced durability within extreme conditions.

​

  • Compatible with reinforcements such as Jesmonite Alkali Resistant 13mm Chopped Glass Strands and Jesmonite Alkali Resistant Quadaxial Glass.

​

  • The technology can be utilised for fine surface detail, castings, premix flat panel and lightweight applications.

​

  • Contains a fine decorative aggregate and powder pigments, carefully controlled to give a consistent decorative surface finish.

FUNCTIONALITY OF AC630

Scalability & Fixing

​AC630 is suitable for larger scale architectural applications and detailed panelised formats including external decorative features. Jesmonite cladding panels can be fixed to most substrates in a fashion akin to conventional GRC or concrete systems.

Manufacturing Methods

 ðŸ”¹ Traditional Pouring Methods
The classic approach! Traditional pouring is ideal for creating detailed casts and solid forms. Jesmonite's smooth consistency allows it to capture intricate details, making it perfect for sculptures, ornamental pieces, and architectural elements. Simply mix, pour into your mould, and let the material do the rest.

🔹 Spray Moulding
Looking to cover large surfaces or achieve a lightweight finish? Spray moulding is your answer. By spraying Jesmonite onto a mould or substrate, you can build up thin layers that are strong yet lightweight. This method is excellent for creating panels, facades, and decorative surfaces with minimal weight addition.

🔹 Trowelling
For those who love a hands-on approach, trowelling Jesmonite offers a tactile experience with creative freedom. This method allows you to apply the material directly onto surfaces, giving you control over texture and thickness. It's perfect for custom finishes, restorative work, or adding unique textures to walls and installations.

🔹 Rotational Moulding (Rota Moulding)
Also known as roto moulding, this technique is fantastic for creating hollow, seamless objects. By rotating a mould while the Jesmonite cures inside, you achieve uniform wall thickness and structural integrity. This method is ideal for producing items like planters, furniture pieces, and complex geometric forms.
