Features Of Sika Curehard 24 Concrete Curing Agent

  1. Penetrates deeply into concrete to react with free lime and form insoluble calcium silicate hydrate (C-S-H) gel.

  2. Enhances surface hardness and abrasion resistance without altering the concrete’s natural appearance or breathability.

  3. Non-toxic, low-VOC formulation compliant with international health and safety standards for indoor use.

  4. Fast-acting — achieves measurable strength gain within 24 hours of application under standard curing conditions.

  5. Water-based, solvent-free chemistry suitable for environmentally sensitive construction projects.

Typical Applications Of Sika Curehard 24 Concrete Curing Agent

  1. Industrial warehouse floors requiring high wear resistance and dust suppression.

  2. Commercial retail spaces and showrooms where aesthetic finish and long-term durability are critical.

  3. Concrete parking structures and ramps exposed to heavy vehicular traffic.

  4. Newly cast interior concrete slabs in residential and office buildings.

  5. Pre-cast concrete elements requiring accelerated surface stabilization prior to handling or finishing.
