Quartz Floor Hardener is a mixture of finely graded nonmetallic Quartz aggregates, plasticizer, and cement binder – an economical concrete floor hardener recommended for both interior and exterior use.

When applied at the proper point in the concrete setting cycle, Quartz Floor Hardener is worked into the concrete to become an integral part of the floor to provide a surface that is highly resistant to abrasion.

Quartz Floor Hardener is available in a natural concrete color in addition to a variety of other colors, including Light Reflective, Tile Red, French Gray, Battleship Gray, and Nile Green.

Features & Benefits

• Minimal surface dusting

• Exterior/interior application

• Increases impact and abrasion resistance up to four times that of plain concrete

• Compliant with American Concrete Institute Standards: ACI 302, ACI 305, ACI 306

• U.S.D.A. accepted for use in facilities where incidental contact with food products is possible

• Provides a high-density surface that resists liquid penetration and is easy to clean and maintain

• Non-fading, non-rusting colors (Light Reflective, Tile Red, French Gray, Battleship Gray, and Nile Green)

Application

• For optimal results, refer to the American Concrete Institute Standard 302 for 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, apply SpecFilm post 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 approved SpecChem ASTM C309 compliant curing compound.

Shelf Life

Shelf life of 12 months when stored in dry conditions away from direct sunlight.
