Flo-Add HF

Hydrogen free expansive and plasticising grout additive

Flo-Add HF is a hydrogen free expansive and plasticising additive for cementitious grout. The addition of Flo-Add HF to the cementitious mixes will produce a high flowable expansive grout; Flo-Add HF reduces the water demand, producing high strength with low permeability and excellent bond to steel.
