Dry Shake Hardeners for Concrete Floors | Sika

Concrete mix w/c ratio should be at least 0.50 to secure the adequate amount of water for hydration of the hardener. Concrete mixes for interior floors should not include air entrainment and should have a measured entrapped air content of more than 3%. Dry shake hardeners are generally not recommended for ultraflat floors.
