Sandstone Oxide (1Kg)

Introducing our exquisite Sandstone Iron Oxide Concrete Colour, a warm and sandy hue inspired by Australia's iconic Bondi Beach. This exceptional concrete colour brings a touch of coastal charm to any indoor or outdoor space. Specially crafted with high-quality iron oxide pigments, our Sandstone Concrete Colour ensures durability and long-lasting vibrancy, making it the perfect choice for architects, designers, and homeowners seeking a premium solution for their concrete colouring needs, especially for GFRC (Glass Fibre Reinforced Concrete) and UHPC (Ultra-High-Performance Concrete) applications.The use of iron oxide pigments guarantees UV resistance, preventing the colour from fading over time, and offering a consistent appearance even in areas with direct sunlight exposure. By varying the amounts of the Sandstone Iron Oxide, you can create unlimited shades of this colour, making it highly customisable to suit individual preferences. Our Sandstone Iron Oxide Concrete Colour is easy to mix and apply, with compatibility across various concrete types and finishes, including stamped, textured, and polished surfaces. Transform your driveway, patio, pool deck, or interior flooring with this stunning shade and create a welcoming atmosphere that reflects the laid-back Australian lifestyle.Beyond concrete colouring, Sandstone Iron Oxide is an adaptable pigment that offers numerous benefits across the construction industry. Its striking blue hue and exceptional durability make it an ideal choice for decorative plaster finishes, exterior coatings, roofing materials, masonry, stucco, and concrete flooring and paving. Additionally, it is widely used in glass production to create intricate designs in products such as plates, vases, and glassware, as well as steel structures and building materials.One unique application of Sandstone Iron Oxide is in GFRC projects. This pigment is extensively used in the production of GFRC panels and cladding to create a distinctive and eye-catching finish. Its excellent durability and resistance to wear and tear make it an ideal choice for any application that requires a strong, long-lasting finish.In summary, Sandstone Iron Oxide is a reliable and versatile pigment that offers a multitude of benefits for the construction industry. Its bright blue colour, superb durability, chemical resistance, and colour fastness make it a popular choice for a wide range of products, from plastics and synthetic materials to paints and coatings. Whether you are working on a large construction project or a small decorative finish, Sandstone Iron Oxide is sure to deliver outstanding results.

Got any question?

Browse through our frequently asked questions to find answers on everything from mould preparation and casting techniques to finishing and long-term maintenance.

Australia’s warm and, in many regions, coastal climate necessitates adjustments during manufacturing. High temperatures can accelerate hydration, so controlled curing environments—such as covering pieces with plastic to retain moisture—are essential. Additionally, lower water-to-cement ratios and carefully selected admixtures help mitigate rapid evaporation and ensure that GFRC develops its designed strength and durability.

Manufacturers address these challenges by:

  • Using precision mixing equipment to achieve a uniform blend and ensure proper fibre distribution.
  • Fine-tuning spray parameters (such as pressure, nozzle design and technique) to avoid voids, pinholes and surface defects.
  • Regular maintenance of equipment and continuous operator training.
  • Adjusting admixture dosages as required to optimise workability and adhesion.

Future trends include increased automation—such as robotic spraying and digital mould design—as well as a greater focus on sustainable practices (e.g. incorporating recycled materials and eco-friendly admixtures). Advances in fibre treatment technology and computer-aided manufacturing are enabling more complex, custom-designed panels. Ongoing research is continually refining mix designs and curing methods to better suit Australia’s diverse environmental conditions.

GFRC is a composite product that combines high‐quality cement, fine aggregates, polymers and alkali‐resistant glass fibres – all premixed to the correct proportions. Its high strength‐to‐weight ratio, durability and capacity for being cast in thin, custom shapes make it ideal for creating stylish and long-lasting benches and tables for both indoor and outdoor use.

GFRC manufacturers must comply with Australian building codes and standards relating to precast concrete, structural performance and safety. This means that production processes, material testing and installation methods are stringently monitored and documented. Close collaboration with local certifying bodies ensures that GFRC products meet all necessary performance and regulatory requirements.

With our premix product, all the ingredients are already proportioned for optimal strength and workability. This means you can focus on preparing your moulds and executing a neat cast rather than measuring raw materials.

Moulds for benches and tables can be constructed from high-density foam, melamine, or even silicone for more intricate designs. It is essential that the mould is smooth, watertight and well supported. Pre-treat the interior with a quality release agent to ensure that the cured GFRC can be removed cleanly.
