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, applySpecFilmimmediately 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 approvedSpecChem ASTM C-309 compliant curing compoundafter the final troweling to ensure proper curing.
