MACt Liquid Grout is a specialised formulation designed to fill pinholes, voids, cracks, and other micro-defects in concrete surfaces—especially after grinding—creating a denser surface that polishes faster and more uniformly. By mixing seamlessly with the dust generated during the grinding process, this cost-effective grout ensures every gap is thoroughly filled, leading to an even uptake of densifiers, colours, or sealers and a flawless, high-gloss finish.

Key Features & Benefits

  1. Fills Surface Defects
    • Pinholes & Cracks: Eliminates annoying gaps and voids left after grinding, including small stone pop-outs.
    • Improved Surface Uniformity: Creates a denser, more polished-looking floor that’s easier to seal or colour.
  2. Dust-Interactive Formula
    • Easy Application: Combines with the fine dust produced by grinding, ensuring consistent coverage and gap-filling.
    • Enhanced Product Absorption: Prevents uneven areas that might otherwise soak in densifier, colour, or sealer.
  3. Faster Polishing
    • Quick Results: Prepares floors for a high-gloss finish efficiently, minimising the time and effort needed for subsequent steps.
    • Smooth, Dense Surface: Reduces polishing passes required, cutting labour costs while boosting overall quality.
  4. Versatile & Cost-Effective
    • Simple Usage: Requires minimal extra equipment; just vacuum, apply evenly, and dampen the surface as needed.
    • Optional Strength Enhancement: Pair with MACt Blended Densifier (if floors are very soft) 24 hours prior to application for maximum surface hardness.

Recommended Usage Instructions

  1. Surface Preparation
    • Vacuum Thoroughly: Remove dust and debris sitting in pinholes or cracks to ensure complete, even filling.
    • Optional Densifier: If floors are highly porous or soft, apply MACt Blended Densifier 24 hours beforehand.
  2. Application
    • Dampen the Surface: Helps prevent excessive absorption of the grout while mixing effectively with grinding dust.
    • Even Coverage: Spread MACt Liquid Grout evenly across the floor; the dust from grinding will naturally blend in to fill voids.
  3. Finishing
    • Allow to Cure: Let the grout settle and dry according to your project needs.
    • Polish as Usual: Proceed with standard polishing steps, now streamlined thanks to a denser, pre-filled surface.

Why Choose MACt Liquid Grout?

  • Uniform Final Finish: Locks in a denser, more consistent substrate, improving the performance of densifiers, colours, or sealers.
  • Time & Cost Savings: Eliminates repeated polishing passes and the need for more complex gap-filling methods.
  • Easy Integration: Works in tandem with standard concrete polishing systems; can be used on its own or alongside densifiers for added hardness.
  • Professional Results: Delivers smooth, high-gloss floors ideal for commercial, industrial, or decorative applications.
For anyone aiming to polish concrete surfaces to a mirror-like sheen—while sidestepping the challenges of pinholes, micro-defects, and uneven absorption—MACt Liquid Grout provides a straightforward, cost-effective solution. By naturally combining with grinding dust, it fills gaps and voids, ensuring your floors take on densifiers, colours, or sealers uniformly and polish to an impeccable finish. Simplify your workflow and boost the quality of your polished concrete projects with MACt Liquid Grout.

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.
