HC-5 – Concrete hardener
The HC-5 – Concrete hardener – lithium based it’s a liquid hardener for concrete surfaces, also suitable for any other kind of material containing calcium carbonate. It penetrates through the micro-pores of the surface, compacting and hardening it and increasing the index of impermeability from inside, making easier the later polishing process and/or the definitive impermeabilization of the surface.
Apply the product before the last step in the polishing process. Spread the HC-5 until the pavement become saturated, let dry for a few hours and remove the residue, finishing the polishing with the last diamond resin pad. The product can also be applied at any time to harden the concrete, even when not performing a polishing work.
COVERAGE: 10 to 15 sq.meters per litre depending upon the porosity of the floor.
