Chemforce Forti-Col EG Silica Densifier

Chemforce Forti-Col EG New Technology Colloidal Silica Densifier

The ultimate densifier for concrete polishing, anti-dusting and slab curing.

Featutres:

• Colloidal silica is the latest and best technology amongst the silicates.
• Minimal (usually zero) colour change with Forti-Col EG™.
• Contains a high concentration of a range of the smallest nano colloidal particles which means:
  • Deeper penetration
  • Fast reactivity & curing
  • More reactive sites resulting in more complex structures & more SiO₂ inside the pores for greater density and better polish
• Makes concrete polishing much quicker as excess product on the surface does not form a hard, gummy film which takes hours to grind off.
• Formulated with advanced additives to optimize penetration.
• Lower, non-caustic pH is safer for people & surfaces.
• Does not break down under UV so lasts for decades, even outdoors.
• Water-based, zero VOC.
• Made at our factory 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.

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.
