C2 Hard™ is the advanced sealer, hardener and densifier for concrete surfaces and a much more effective alternative to conventional sodium or potassium silicate hardeners. This patented lithium silicate treatment deeply penetrates and reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores. Conventional hardeners deposit high concentrations of sodium or potassium salts, which contribute to surface ASR, resulting in deterioration of concrete. Surfaces treated with C2 Hard™ will resist damage from water, surface abrasion, eliminate dusting and simplifies maintenance.
C2 Hard™ should be used where the specification calls for just a sealed floor with or without burnishing and no grinding or polishing is required. Typically this product would be used on new slabs either at the time of placement or after a wet cure, chemical cure or after 28 days of curing or construction. C2 Hard™ can also be use on a previously densified floor where sodium or potassium was used at one time and the surface is starting to dust or deteriorate.
Patented formulation of C² Hard™ contains a highly reactive lithium catalyst, which achieves a much greater penetration into the floor surface and triggers a much faster and more complete reaction with the concrete than traditional sodium silicate.
C2 liquid hardeners/densifiers will outlast. C2 contains chemicals heavy in silica, which reacts with calcium hydroxide in concrete, densifies and seals micro pores in the top layer of the concrete (“wear zone”), strengthens and hardens the surface, creating a permanent impregnation of the concrete floor. C2 Hard™ is breathable and UV stable. Will not yellow, discolor, peel or flake.
Greater Abrasion Resistance
Concrete floors treated with C² Hard™ will significantly improve abrasion, in comparison to conventional sodium or potassium hardeners.
In ordinary concrete, tiny particles of dust are pushed to the surface through an upward force called hydrostatic pressure, resulting in efflorescence, which leads to dusting. C2 Hard™ eliminates efflorescence and prevents dusting making concrete easy to maintain.
Improves Stain Resistance
By densifying and sealing the surface, C2 Hard™ transforms a porous concrete floor into a floor that is dense enough to repel water, oil, and other contaminants, preventing them from penetrating the surface.
Reduces or Eliminates ASR
(Alkali Silicate Reaction) due to high lithium content. High concentrations of sodium or potassium salts, which will contribute to surface crazing and surface ASR, are not present in C² Hard™. Lithium will not absorb water or contribute to floor sweating.
Reduces Tire Marks
The rough, uneven texture of natural concrete causes tires to abrade, adding to their wear. A concrete floor treated with C2 Hard™ will make the entire surface smooth, preventing this abrasion and leaving minimum tire marks on the floor.
Improves Condition of Old Floors
As concrete ages, surface stress, delaminating, curled cold joints, and other problems can arise. C2 liquid hardeners/densifiers combined with our customized grinding and polishing technique can remove the top surface layer of the old concrete and strengthen the floor, increasing its impact and abrasion resistance.
Little or No Production “Down Time”
Cures quickly. Floor can be put into service immediately after the application process is complete. Due to the cleanliness of the process and the lack of toxic or hazardous chemicals, floors can often be serviced while the plant is in full production.
C² Hard™ improves performance, appearance and light reflectance of new and old floors. It will reduce an energy bill. A treated floor will lower maintenance costs significantly through reduction in upkeep (no waxing), and reduced tire wear.
Tested and conforms to California Collaborative for High Performance School Indoor Air Quality standards. Use can contribute to LEED® for schools points.
C2 Hard™ is water-based, contains no solvents, non- toxic, no smell, complies with all known national, state and district AIM VOC regulations, non-mutagenic & carcinogenic (safe in food preparation areas), non flammable, low odor, fast drying, easy to apply.
Compatible with all C² lithium hardeners, densifiers, sealers and cleaners.
Helps Concrete Curing. For best results, use C² Hard™ first for hardening, sealing and densification followed with a water-based, dissipating curing membrane. C² Hard™ should not be substituted as a curing agent.
Easy to Use. Reduces application time and costs of burnishing and diamond polishing operations. One step application. No white salty spots on concrete. No scrubbing and flushing required after application. No caustic wastewater.
Ordinary cleaning can easily remove blemishes and tire marks.
Lithium does not absorb water or contribute to floor sweating.
An extremely hard marble-like shield and permanent impregnated surface can be achieved for the life of the concrete with one single application.
May be applied to broom finished, steel troweled, power troweled or burnished concrete finishes before final cure.
Much safer and easier to apply than conventional sodium or potassium silicate hardeners.
C2 products are patented formulations.
Produces a fast surface gloss, which improves with traffic and maintenance.
Will not yellow, discolor, peel or flake.
Slip resistance is not diminished with high gloss and hardness.
Cures quickly. Most floors can be opened to traffic within one hour of treatment.
Lithium based C² Hard™ provides complete and consistent densification as compared to sodium and potassium based densifiers.
Complies with all known national, state and district AIM VOC regulations:
C² Hard™ is recommended for use on concrete classes both new and existing.
Safe for use in food and drug processing industries.
2 years in unopened, factory sealed container
All information provided is accurate to the best of our knowledge and is to be used strictly as a guide. Handling conditions, installation and use are not in our control therefore we cannot guarantee the results.
C² Hard™ does not meet the ASTM-309 Standard. To meet this standard and create a membrane, use a dissipating, water-based curing agent.
Will not repair damaged surfaces and cracks.
Not recommended for use on plastic concrete, mortar, resin-based terrazzo mixes and painted or asphaltic and non-cementitious surfaces.
