SpecPlate NOX
Non-oxidizing metallic dry-shake floor hardener
SpecPlate NOX is a high-quality blend of non-oxidizing metallic aggregates, plasticizers, and cement binders. It is specifically designed to provide maximum abrasion resistance for interior concrete floors. When integrated into fresh concrete slabs, SpecPlate NOX creates a surface highly resistant to abrasion, impact, and point loading, making it ideal for areas prone to frequent moisture and water exposure. Additionally, SpecPlate NOX is utilized in the construction of iron-armored joints and is available in natural Concrete Gray and Light Reflective colors.
- Provides a non-rusting, high-strength wearing surface suitable for areas with frequent moisture and water exposure.
- Increases impact and abrasion resistance up to eight times that of plain concrete.
- Offers a high-density surface that resists liquid penetration and is easy to maintain and clean.
- Resistant to surface dusting, spalling, and deterioration due to abrasion.
- Light Reflective formula enhances lighting efficiency and helps reduce energy costs.
Application
Application Guidelines:
- Follow the American Concrete Institute Standard 302 for general floor and slab construction guidelines.
- Aim to perform all work under a roof whenever possible. Environmental conditions that affect drying and setting times will also impact the timing of hardener application.
- Proper concrete mix design must be reviewed and approved by SpecChem before placement.
- Prepare the area by calculating the required number of bags based on the coverage rate, and ensure the concrete is placed to the finish grade level and compacted with a wooden bull float.
Special Conditions:
- Apply SpecFilm to the surface immediately after bull floating in conditions that promote rapid surface drying, such as low humidity, wind, or sunlight.
Placing the Hardener:
- The application should consider the concrete slump, job site conditions affecting drying, and the necessary coverage. Begin application at the perimeter as it sets quicker than the interior.
- Use a dry-shake method after concrete bleeding. Apply two-thirds of the hardener initially, allow it to absorb moisture, then float. Follow immediately with the remaining one-third and complete the machine float after the slab stiffens.
Curing:
- Apply an approved SpecChem ASTM C-309 compliant curing compound post-final troweling to ensure optimal curing.
