Forti-Kal™ is a potassium silicate densifier for concrete. It is a pure premium quality potassium silicate. It is ready for use formulation at 15% concentration.
If used correctly with no excess product left on the surface, Forti-Kal will not substantially change the slip resistance of the surface.
Forti-Kal is UV and chemically resistant and, once cured, will last for decades, even outdoors. Forti-Kal is water-based, is zero VOC, and made in Australia.
- 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-Kal™ will form CSH hydrogel inside the pores of the concrete, substantially restricting water bleed and evaporation and retaining water so the concrete can cure properly
- Primer / Moisture Barrier for green concrete. Freshly poured concrete contains a lot of water which will evaporate and cause coatings to blister and delaminate, salts to redeposit underneath and lift tiles, damp and mould growth under carpeting, insulation matting, wood etc. Therefore 60 days of curing is usually required before applying a coating or floor covering over the fresh slab. Treating the concrete with penetrating Forti-Kal™ will form CSH hydrogel inside the pores of the concrete, substantially restricting water bleed and evaporation, so coatings and other floor coverings can be immediately applied. 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 there can be chemical spills. A suitable acrylic or epoxy class 3 membrane with sufficient elasticity, elongation and chemical resistance is recommended.
- Concrete Densifier for concrete polishing. Forti-Kal™ is a potassium silicate, which has a smaller molecular size than a potassium silicate so can be used to impregnate concrete in the earlier stages of grinding and later stages, after using a 400 grit polishing pad (impregnating twice is recommended for optimal results.
