Product Description

The C² range of products provide a great solution for Concrete Hardening and Densification. C² products are formulated with premium lithium technology, creating shine and a durable surface, providing a superior alternative to sodium and potassium hardeners.

 C2 Superhard is a premium sealer hardener and densifier for concrete with the maximum lithium content. Treated surfaces will resist damage from water, surface abrasion and have reduced maintenance through less dusting.

 C2 Hard is an advanced sealer, hardener and densifier for concrete. This formulation achieves much greater penetration into the surface and triggers a much faster and more complete reaction with the concrete than traditional sodium silicate. An excellent solution on floors previously densified with sodium or potassium hardeners when the surface is starting to dust or deteriorate.

 C2 Hard Blend is a concentrated lithium silicate blend hardener & densifier for concrete. Specifically designed for steel troweled, power troweled or burnished concrete finishes. Provides better abrasion resistance than conventional hardeners and can be burnished for a quick sheen.

 C2 Seal seals concrete with a rich, high glossy finish. Perfect for application on standard or decorative concrete and terrazzo. Protects and enhances the color intensity of integrally colored and color stained concrete and maximizes light reflectance.

 C2 Salt hard + is a pre-measured additive specifically formulated to mix with C² Hard™ or C² Super Hard™. Hardens, dustproofs and protects from abrasion, moisture intrusion and chloride salts.

 C2 Ultra seal is a durable, chemical resistant, high-gloss protective coating. Ideal for specialty areas that may have exposure to accidental spills of food products, household cleaners and industrial solutions.

 C2 Dura seal is a UV Stable, non-yellowing, protective coating for concrete. Specifically formulated for exterior concrete and increases stain resistance.

Technical and Environmental Benefits

Low VOC - The nominated products are low VOC and can contribute points in Green Star NZ and Homestar.

Improved Reflectivity - The reflective properties of a densified floor surface, increases the lighting in facilities. If the lighting system is designed with this in mind, the lighting energy requirements can be reduced due to the higher floor reflectivity.

Durability - C² liquid hardeners/densifiers will outlast topcoats. A permanent impregnation of the floor surface can be achieved for life of the concrete with one single application

Strengthening of Floor Surface - C² liquid hardeners/densifiers are chemicals heavy in silica, which reacts with calcium hydroxide in the concrete to fill pores, strengthen and harden the surface wear layer.

Greater Abrasion Resistance - Even the most perfect bare concrete floors will wear off relatively easily in an industrial traffic conditions. Floors treated with C² liquid hardeners/densifiers will significantly improve abrasion resistance. 

Slip Resistant - A treated floor surface, though shiny, does not create a slippery floor. 

Less Maintenance - Most floor systems, including tile and linoleum, require aggressive scrubbing to maintain a clean environment and nice appearance. Surfaces treated with C² liquid hardeners/densifiers are tightly compacted - reducing stains - and do not require any waxing or stripping to maintain the sheen.

Application and Purpose

Strengthening of Floor Surface - C² liquid hardeners/densifiers are chemicals heavy in silica, which reacts with calcium hydroxide in the concrete to fill pores, strengthen and harden the surface wear layer.

Durability - C² liquid hardeners/densifiers will outlast topcoats. A permanent impregnation of the floor surface can be achieved for life of the concrete with one single application.

Can be used for any Residential or Commercial Application where a high quality exposed concrete floor finish is part of the design requirements.

Installation and Maintenance

Concrete must be dry with no residual moisture. Prepare concrete surface and remove any residual moisture (internally this is done usually with a wet and dry vacuum). Allow to dry. Apply C2 concrete sealer.
