Chemforce Forti-Col EG Silica Densifier

CHEMFORCE FORTI-COL EG – ADVANCED COLLOIDAL SILICA DENSIFIER

Forti-Col EG™ is a high-performance concrete densifier engineered for polishing, anti-dusting, and slab curing. Using the latest colloidal silica technology, it delivers exceptional penetration, rapid curing, and long-lasting results.

KEY FEATURES

• Utilises cutting-edge colloidal silica technology for superior performance
• Minimal to zero colour change after application
• High concentration of ultra-small nano colloidal particles for:
  • Deeper concrete penetration
  • Faster reactivity and curing
  • More reactive bonding sites, creating complex internal structures
  • Increased SiO₂ content for improved density and polish
• Speeds up concrete polishing – no hard, gummy residue to grind away
• Enhanced with advanced additives for optimised penetration
• Non-caustic, low pH – safe for people and surfaces
• UV stable – will not degrade, even outdoors
• Water-based and zero VOC
• Proudly manufactured in Melbourne, Australia

Product Applications

Concrete Densifier for Concrete Polishing:

• High concentration colloidal silica densifier with the smallest particle sizes – smaller than traditional silicates and other colloidal silica densifiers.
• Despite the small particle size and greater penetrating power, the high concentration makes it ideal for EARLY densification after 30 to 100 grit metal grinding pads.
• Can be used for later densification after 50 to 400 grit resin pads, but Standard Forti-Col™ is more cost effective for later densification as concrete is less porous and doesn’t usually require a super concentrated product.

Concrete Slab Curing and Anti-Dusting:

• Highly concentrated which makes it ideal to treat fresh slabs to minimize water evaporation and optimize concrete curing.
• Trowelled slabs should be trowelled with Forti-Trowel™ and then treated with Forti-Col EG™.
• Forti-Trowel™ is formulated with special colloidal particles with a delayed reaction time so it doesn’t interfere with the initial reaction of the cement and hardening of the concrete, while improving trowelling and creating a tighter pore structure on the surface of the concrete.

How to Use

IMPORTANT: Always test on an inconspicuous area and allow to dry to check the result.

Slab Curing & Anti-Dusting Treatment:

• Ensure the concrete is dry inside before applying. If applying on freshly poured (green) concrete, give the concrete a minimum of 2 hours cure time to allow concrete to react and use up most of its water before applying.
• Apply when surface temperature is above 2°C (36°F) and ideally below 32°C (90°F).
• Apply generously with a pump sprayer, saturating the surface evenly so it remains glistening wet for at least 5–10 minutes. Avoid pooling.
• If all the Forti-Col EG™ fully penetrates within 10 minutes, apply a second coat.
• DO NOT dilute – Forti-Col EG™ is ready-to-use out of the container. Tap water can reduce its penetrating power.
• Application rate per coat: approximately 4 to 10 m²/L. Application rate will be lower if applying to a trowelled concrete surface, particularly if trowelled using Forti-Trowel™.

Concrete Polishing:

• Best choice for the earlier stages of densification when concrete is rough and pores are very open – after grinding with 30 to 80 grit metal-bond pads.
• Can also be used for later densification – recommended after 200 resin pads, but can be used after 50 to 200 grit resin pads. Standard Forti-Col™ is more cost effective for later densification.
• Apply generously with a pump sprayer, saturating the surface evenly so it remains glistening wet for at least 5–10 minutes. Avoid pooling.
• If all the Forti-Col EG™ penetrates within 10 minutes, apply a second coat.
• Application rate per coat: approximately 4 to 10 m²/L for early densification.
• DO NOT dilute – Forti-Col EG™ is ready-to-use out of the container. Tap water can reduce its penetrating power.

Appearance

• Colour: Clear to slightly opaque, colourless to light straw yellow liquid
