Sodium (N) Potassium (K) Lithium (Li) Silicates
Developed in the 1930s (N&K) and late 1990s (Li)
Used to penetrate and harden concrete
Largest molecular ion size prevents deep penetration providing deepest (4-5 mm)
Varying degrees of reactive “Sites” provide low to moderate chemical reaction and bonding time
Water soluble (N&K) causes expansion/contraction in Wet/Dry cycles. Li is insoluble and remains stable
Very corrosive, increases the pH of the concrete to (pH 11-13)
Not good for sealing concrete
Generates corrosive, gelatinous slurry that must be scrubbed away and disposed of as hazardous waste
Requires continuous stirring and scrubbing to create any reaction with concrete.
May contribute to sweating and white deposits (N&K)
Requires dwell time
Why our Concrete Hardener, Concrete Densifier ns is superior to traditional Concrete Hardeners. Developed in the 2000s. Nano-Silica Concentrated dispersion of Nano-silica in water
Concrete hardeners based on Sodium (N) Potassium (K) Lithium (Li) Silicates Developed in the 1930s (N&K) and the late 1990s (Li), most of our competitors in Europe are based on this.
SEE COMPARISON OF CONCRETE HARDENERS, DENSIFIER SEPARATE PAGE.
-Works great even if the concrete slab is decades old
-Reacts with the substrate within 1-2 minutes.
-Spray it on the concrete until the surface is saturated and it stops absorbing the liquid and stir, this is the only application step required before polishing the concrete.
-No processing of the material in the concrete
-Nano Densifiers penetrate deeper and react more effectively than traditional densifiers.
-Just one hour for a reaction and it's ready to polish. No waiting overnight.
-No corrosive gel to scrub off.
-Nothing to throw away
-No risk of white precipitates
-Can be used with our ConcreteShield ns for extra shine and protection.
-Delivered in Concentrate. Lower shipping costs – why pay to ship water.
-Penetrates quickly, deeply and cleanly into the concrete
-The particles in ConcreteDensfier ns are much more reactive than in conventional Concrete Hardeners/Densifiers.
-The particles form cementing compounds that harden and densify the surface with less waiting and less waste.
-Safer and more environmentally friendly than traditional Concrete Hardeners/Densifiers
-The product will provide a higher gloss and DOI when polished compared to conventional Concrete Hardeners/Densifiers.
