SpecPlate Hardener
Metallic dry-shake floor hardener
SpecPlate Hardener is a well graded blend of metallic aggregates, plasticizer and cement binder. It provides maximum abrasion-resistance to interior concrete floors. When incorporated into fresh concrete slabs, SpecPlate Hardener 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 high strength wearing surface
- 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.
Application
Application Instructions:
- Adhere to the American Concrete Institute Standard 302 for general guidelines on floor and slab construction.
- Ensure all application work is conducted under a roof, if possible. Conditions that influence drying and setting times will affect the hardener application times.
- Calculate the necessary quantity based on the area coverage rate. Prepare the concrete to a finished grade level and compact using a wooden bull float.
Special Conditions:
- In environments with conditions that accelerate surface drying, such as low humidity or exposure to wind and sunlight, apply SpecFilm immediately after bull floating.
Placing:
- The application of the hardener should consider the concrete slump, environmental conditions, and the specified coverage. Apply to perimeter areas first as they set quicker than the interior.
- Use a dry-shake process after the concrete has bled. Apply two-thirds of the hardener initially, allow it to darken as it absorbs moisture, then float using a wood or machine tool. Immediately follow with the remaining third and finalize with machine floating.
- Do not add water during finishing as this weakens the surface. Instead, aim for a hard-troweled finish for optimal durability.
Curing: Apply an approved SpecChem ASTM C-309 compliant curing compound after the final troweling to ensure proper curing.
