Accelerating Additive


DESCRIPTION: Rapid Set® FAST is an admixture designed to accelerate the hardening of Rapid Set products in low temperatures.

USES: Use FAST with Rapid Set cement products ONLY. FAST is ideal when accelerated strength is needed due to lower temperatures. FAST may be used in combination with other Rapid Set® Concrete Pharmacy® admixtures.

DIRECTIONS: Dissolve FAST into the mixing water. Use 1 to 5 packets per 50-lb to 70-lb bag of Rapid Set product to achieve the desired acceleration. Mechanically mix to complete dispersion (1 to 2 minutes). Add Rapid Set product to accelerated mix water. Cement will harden quickly while mixing.

SHELF LIFE: FAST has a shelf life of 12 months when stored properly in a dry location, protected from moisture, out of direct sunlight, and in an undamaged packet.
