Sprayed trials should be conducted to determine the optimum dosage of Proset AF to meet the performance requirements by using the materials and conditions in actual use.
Dosage of Proset AF will vary depending on the performance requirements of the sprayed concrete, cement type, age and content, temperature of the
sprayed concrete, substrate and air, the water to binder ratio as well as the other admixtures and materials in the concrete mix.
Typical dosage is between 5.0 - 7.0 litre/100 kg of cementitious and cement replacement material, including PFA, GGBFS or microsilica, which can be used as a starting point for the trials.

Proset AF complies with ASTM C1141/C1141M, Types I & II, Grade 9, Class A.
