Material & Application Notes

It’s a cost-effective solution for hardening concrete floors, suitable for both indoor and outdoor applications. Creates a dense surface that minimizes liquid penetration and simplifies cleaning and maintenance. Reduces surface dust.

Why Contractors Choose It

Contractors choose Quartz Floor Hardener when surface prep, removal, or cleanup needs to be handled with a job-specific chemical instead of guesswork.

Application

For optimal results, refer to theAmerican Concrete Institute Standard 302for floor and slab construction guidelines.

Ideally, work under a roof. Factors like low humidity, wind, and sunlight that accelerate surface drying also influence hardener application timing. Use a mechanical spreader for even distribution over fresh concrete.

Before application, ensure concrete is at grade level and smoothly compacted using a wooden bull float. If conditions promote rapid drying, applySpecFilmpost bull floating to mitigate quick surface water loss.

Application Tips:
  • Application timing should consider concrete slump, job site conditions, and hardener coverage. The perimeter sets faster than the center—start application at the edges.
  • After concrete placement, allow the first two-thirds of hardener to absorb moisture before a final float. Follow up immediately with the remaining one-third and complete the floating process.
  • Maintain a flat trowel during edge work to avoid blistering. Re-trowel with lowered blades if necessary.
  • Do not add water to aid finishing; it weakens the surface. A hard troweled finish is ideal.
  • Curing:After the final float, apply an approvedSpecChem ASTM C309compliant curing compound.
