SpecPlate NOX
Non-oxidizing metallic dry-shake floor hardener
SpecPlate NOX is a well graded blend of nonoxidizing metallic aggregates, plasticizer and cement
binder. It provides maximum abrasion-resistance to interior concrete floors. When incorporated into fresh concrete slabs, SpecPlate NOX will provide a surface which is highly resistant to abrasion, impact and point loading even in areas subject to frequent moisture and water exposure.
- Provides a non-rusting, high strength wearing surface in areas subjected to frequent moisture and water.
- Increases impact and abrasion resistance up to eight times that of plain concrete
- Provides a high density surface that resists liquid penetration and is easy to clean and maintain
- Resistant to surface dusting, spalling, and deterioration due to abrasion.
- Light Reflective formula offers improved lighting and reduced energy cost.
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.
