Concrete Mould Supplies & Form Preparation Products
Getting a clean, consistent release from your mould is just as important as the mix design itself. Domcrete stocks a professional range of concrete mould supplies and form preparation products to help fabricators get consistent, repetitive castings for production.
The range covers chemical release agents for rigid and flexible moulds, paste wax for non-porous mould surfaces, water-based release agents for environmentally sensitive applications, stainless steel caulking tools for sealing mould joints, and modelling clay for form building and detail work. These products are used by GFRC fabricators, concrete benchtop makers, and precast concrete studios across Australia and New Zealand. For a broader range of mouldmaking supplies, including silicone, urethane, and tooling materials, visit the Mould Materials section of the Domcrete store.
Frequently Asked Questions
What mould release agent should I use for GFRC and concrete?
The right mould release agent depends on the type of mould you are using:
- Rigid moulds (melamine, Formply, foam, timber, fibreglass) — Crete-Lease 880 is the industry standard for GFRC and decorative concrete. It is a chemical release agent that lubricates the mould surface and provides a reliable, clean release.
- Non-porous or polished mould surfaces — Smooth-On Sonite Wax is a versatile paste wax used for sealing and protecting mould surfaces. It is particularly useful on complex, rigid moulds, where it can be applied and buffed into the surface before applying Crete-Lease 880 to assist with mould release.
- Smooth-On Vytaflex Moulds – Urethane Moulds — Smooth-On AquaCon is a water-based release agent specially designed to facilitate demoulding of GFRC/ECC and concrete castings from urethane and Vytaflex rubber moulds.
If you are unsure which release agent suits your mould type, contact the team for advice.
What is modelling clay used for in concrete mouldmaking?
Modelling clay plays a practical role in concrete mould preparation and form building. In GFRC and decorative concrete fabrication, it is most commonly used for:
- Sealing mould joints and corners — pressing clay into internal corners, seams, or gaps between form sections to prevent concrete from bleeding through and creating unwanted fins or flashing on the cast piece
- Creating chamfers and radii — rolling clay into a cove or fillet and pressing it into sharp internal corners softens the transition and reduces the risk of stress cracking at the demould stage
- Building up detail or texture — clay can be shaped and pressed into a mould to create recessed details, texture patterns, or custom profile elements before casting
Sculptex Modeling Clay (Soft) is the option stocked by Domcrete, and is compatible with all concrete and GFRC mould types. It works alongside the stainless steel caulking tools for clean, precise application.
