Introducing Forti-Trowel™: An Advanced Colloidal Silica Finishing Aid for Concrete Slabs

When it comes to achieving a flawless concrete finish, the right tools and additives can make all the difference. Forti-Trowel™ is a groundbreaking colloidal silica trowelling aid designed specifically for freshly poured concrete slabs, giving professionals the edge they need in speed, surface finish, and long-term durability.

Whether you’re working on residential flooring, commercial slabs, or precast panels, Forti-Trowel™ delivers a smoother, faster, and cleaner finishing experience—especially in modern concrete mixes enriched with plasticisers or pozzolans.

Why Use Forti-Trowel™? Key Benefits at a Glance

Forti-Trowel™ utilises special spherical nano-silica particles suspended in a high-performance water-based carrier. These particles actively modify the concrete surface as it’s being finished.

Here’s how it works—and why it’s an essential tool for today’s concrete professionals:

Improves Workability

  • Nano-silica lubricates the surface, making helicopter trowelling faster and roller screeding smoother, even on sticky, low water content mixes.

Enhances Surface Quality

  • Delivers a cleaner, glossier, and more consistent finish with minimal drag—helping to eliminate streaks, burn marks, and chatter.

Reduces Evaporation & Extends Trowel Window

  • Creates complex silicate structures that tighten the surface pore structure and slow down water loss, giving you a longer window to work, especially useful in warmer climates.

Safe & Eco-Friendly

  • Non-caustic, low pH, water-based formulation with zero VOCs—safe for workers, tools, and the environment.

  • UV-resistant for extended performance, even in direct sunlight.

Made in Australia

  • Proudly manufactured in Melbourne, ensuring consistent quality and local support.

Perfect Pairing: Forti-Trowel™ + Forti-Col EG™

For optimal slab performance and curing:

  • After finishing with Forti-Trowel™, apply Forti-Col EG™ approximately 2–4 hours after pouring, once the initial cement reaction has taken place.

  • This two-step system ensures superior densification, curing, and anti-dusting on all concrete surfaces.

How to Use Forti-Trowel™ – Simple Application Guide

Forti-Trowel™ is ready-to-use and requires no dilution.

🛠️ For Fresh Concrete Slabs

  • Spray an even, generous coat over the entire freshly poured slab using a pump sprayer.

  • Start trowelling immediately—manual or helicopter trowels will glide more easily over the surface.

  • If using a roller screed, spray before screeding to minimise concrete buildup on the roller.

  • Reapply as needed in areas that aren’t responding as well to trowelling.

  • ⚠️ SAFETY TIP: Trowels will move more easily across the lubricated surface. Slow down near edges to avoid overshooting or creating uneven areas.

🧱 For Precast Panels

If using Forti-Trowel™ on precast concrete panels, spray the exposed surface during finishing, and once hardened, follow up by applying Forti-Col EG™ to all six sides for full-surface curing and densification.

Storage, Packaging & Safety

  • Shelf Life: Best used within 1 year from manufacture.

  • Storage: Store between 2 – 32 °C (36 – 90 °F), away from direct sunlight, in a tightly sealed container.

  • Packaging: 🧴 Available in 20L (5.3 gal / 20kg) containers.

  • Transport: Non-regulated for transport (TDG UN compliant).

Elevate Your Finishing Process

In today’s construction environment, precision and productivity go hand-in-hand. Forti-Trowel™ enables faster finishing with less effort, better results, and a longer-lasting surface.

Whether you’re working in hot weather, using a low-water concrete mix, or simply looking to improve your slab finishing quality, Forti-Trowel™ is your secret weapon for cleaner, stronger, more professional results.
