Chemforce Forti-Trowel Colloidal Silica Trowelling Aid

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

Forti-Trowel is an advanced, premium colloidal silica product designed specifically for freshly poured concrete slabs. It lubricates the wet surface with special spherical nano-silica particles, improving trowelling performance and delivering a superior finish.

Features

• 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 above 32 °C)
• Apply Forti-Col EG™ 2–4 hours after pouring for optimal curing
• Lower, non-caustic pH – safer for workers and surfaces
• Water-based, UV-resistant, and zero VOC formulation
• 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.

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