Chemforce Forti-Trowel Colloidal Silica Trowelling Aid

Chemforce Forti-Trowel – Advanced Colloidal Silica Trowelling & Finishing Aid

Forti-Trowel™ is a premium new-technology colloidal silica trowelling and finishing aid designed for freshly poured concrete slabs. This product enhances trowelling performance, improves surface quality, and optimizes slab curing while being safe, eco-friendly, and UV-resistant.

Key Benefits of Forti-Trowel

• Special spherical nano-silica particles lubricate the wet concrete surface for smoother trowelling.
• Enables quicker helicopter trowelling with a superior finish.
• Reduces stickiness in low water content, plasticised, and pozzolan-enriched concrete for cleaner, easier roller screeding.
• Creates complex silicate structures in the outer concrete layer, resulting in smaller pores and slower water evaporation.
• May extend trowelling time in warm weather (not recommended for pouring above 32 °C).
• For optimal curing, apply Forti-Col EG™ to the trowelled surface 2–4 hours after pouring.
• Lower, non-caustic pH – safer for workers and surfaces.
• Water-based, UV-resistant, and zero VOC formulation.
• Proudly manufactured in Melbourne, Australia.

How to Use Forti-Trowel

1. Apply a generous, even coat of Forti-Trowel™ over the freshly poured concrete using a pump sprayer and begin trowelling immediately.
2. When using a roller screed, spray evenly before screeding to reduce sticking and improve results.
3. Helicopter trowel as usual, spraying additional Forti-Trowel™ in areas where performance needs improvement.
4. Do not dilute – product is ready-to-use at optimal concentration. Adding tap water may reduce effectiveness.
5. For prefabricated concrete panels, consider spraying the trowelled face and all other sides with Forti-Col EG™ for enhanced curing, densification, and anti-dusting.

Important Safety Tips

Your trowel will glide more easily over the surface – work slowly near edges to avoid overshooting the slab.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
