Forti-Col™

Colloidal silica densifier for concrete.

Clear

New technology colloidal silica densifier for concrete. Premium curing and anti-dusting treatment for freshly poured slabs.

Product Technical Benefits
  • New Colloidal Silica technology.
  • Smaller nano-particles = better penetration.
  • More reactive, superior densification, faster curing.
  • Lower, non-caustic pH – safer for people and surfaces.
  • UV and chemically resistant. Lasts for decades, even outdoors.
  • Water-based, zero VOC.
Product Applications
  • Concrete Densifier for concrete polishing.
    Forti-ColTM is a colloidal silicate with the smallest particle size – smaller than other silicates so it can be used to impregnate concrete in the earlier stages of grinding (after 80 to 100 grit grind) and later stages (after using a 400 grit polishing pad).
    Impregnating twice – once in the early grinding stages and again after the 400 grit pad, is recommended for optimal results.
  • Anti-dusting and curing treatment for green (freshly poured) concrete.
    To attain full strength, newly poured concrete needs to retain its water content for long enough for the maximum amount of cement to react and form the correct hydrogels to make the maximum number of bonds
    Treating the concrete with penetrating Forti-ColTM will form CSH hydrogel inside the pores of the concrete, substantially restricting water bleed and evaporation so water is retained and the concrete can cure properly. Because Forti-ColTM is more reactive and has more bonding sites per molecule, it builds on itself and forms better hydrogel structures in the pores than other silicates.
  • Primer / moisture barrier membrane for green concrete.
    Treating the concrete with penetrating Forti-ColTM will form CSH hydrogel inside the pores of the concrete, substantially restricting water bleed and evaporation so coatings and other floor coverings can be applied immediately. Freshly poured concrete contains a lot of water which evaporates and causes coatings to blister and delaminate, salts to redeposit underneath and lift tiles, damp and mould growth under carpeting, insulation matting, wood etc. So, slabs are usually left to cure for 60 days before installing flooring.

NOTE: If a 100% membrane is needed against water and water vapour, for example:
a) areas where water can pool and sit for extended periods, such as bathrooms
b) areas where concrete will move and crack over time.
c) surfaces where there can be chemical spills
a suitable acrylic or epoxy class 3 membrane with sufficient elasticity, elongation and chemical resistance is recommended.

Pack Sizes

How to Use

1. Read full How to Use instruction before applying Forti-ColTM
2. Test on an inconspicuous area and allow to dry to check the result.
3. Ensure the concrete is dry inside before applying. If applying as a primer / anti-dusting / curing treatment on freshly poured (green) concrete, it is recommended to give the concrete a minimum of 2 hours cure time before applying, depending on the weather.
4. Apply when surface temperature is above 2°Celsius (36° F) and below 27°Celsius (80°F).
5. Apply generously with a pump sprayer, coating the surface evenly so it remains glistening wet for at least 2 minutes. AVOID POOLING.
6. DO NOT over apply – you want all of the product to penetrate without leaving any excess on the surface. If excess product is left to dry on the surface, it will need to be ground off.
7. How much Forti-Col™ to use:

a)  As a primer / membrane / anti-dusting treatment: for these applications it is important to achieve maximum penetration and volume of the product so that the pores are sufficiently filled. Minimum 2 coats recommended.
b)  For optimal polished concrete, impregnate the concrete twice:

i. First impregnation – after grinding with 80 to 100 grit metal-bond pad. If the first coat penetrates within 5 minutes, apply a second lighter coat (and further coats if necessary).
ii. Second impregnation – after 400 grit resin bond pad. If it is not penetrating well, dilute 2 parts Forti-Col™ to 1 part water.
iii. Allow treated surface to cure for minimum 4 hours before grinding. Forti-Col™ cures faster than sodium, potassium, lithium densifiers, but longer cure = harder = more shine.

8. Application rate PER COAT: approximately 6 to 15m2 / L (240 to 600 square ft / G) depending on concrete density and porosity.

9. Recommended Dilution Ratios:
a) Forti-Col™ is a ready-to-use out of the container, but for freshly poured or dense concrete, Forti-Col™ can be diluted a little more – 2 parts Forti-Col™ to 1 part water (no more than 1 part Forti-ColTM to 1 part water).
