Winter Mix Fast-Set Mortar Accelerator 1# Bag
Fast-Set powder set accelerator is a pre-measured, chloride-based admixture designed to speed up the chemical reaction between cement and water in mortar batches. Produced by Illinois Products Corporation, this white powder increases early strength development and generates heat to help protect against frost damage during cold weather masonry work. While it is not an antifreeze, it allows masons to work normally in temperatures as low as 15°F and is also effective in warmer weather for anchoring "floaters" like glass block or stone by allowing the mortar to stiffen more quickly.

Concrete Calculation Disclaimer:
Calculations provided by this tool are for estimation purposes only. Actual yardage may vary due to site conditions, such as uneven subgrade or bulging forms. To ensure you have enough material, it's recommended to add an additional 1/4 to 1 cubic yard to the calculator results. Depending on the subgrade's levelness, larger pours of 20 yards or more may require up to 10% additional.
