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.
