Forti-Col™ is a new technology colloidal silica densifier for concrete polishing, concrete curing, anti-dusting, and sealing of fresh concrete slabs.
Colloidal silica is the latest and best technology among the silicates. It has a smaller molecule size for better penetration and quicker curing. The smaller molecule size means it covers a greater surface area with more reactive sites which means better CHL (Hydrogel) structures inside the pores.
It is formulated with advanced additives to optimize penetration. It contains smaller particles than other colloidal densifiers. It has lower, non-caustic PH that is safer for people and surfaces. It does not break down under UV so it lasts for decades, even outdoors. It is waterbased, has zero VOC, and is made in Australia.
- Concrete Densifier for concrete polishing. Forti-Col™ 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-Col™ 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-Col™ 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-Col™ 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.
