Water Reducer 205 is a powdered polycarboxylate based plasticizer and pozzolan blend. It is a dry, white, multi-component material that can also replace pozzolan in certain mix designs. Ideal for use in GFRC face and backer coats, or as a water reducer in any concrete formulation. This unique blend offers both water reducing capability as well as pozzolanic benefits, improving the workability, strength and durability of concrete.
Dosage Rate: 0.5 - 10% of Cement Weight
Water Reducer 205 has a wide range of dosage rates, depending on the application and mix. In GFRC face coats, use the lower end of the dosage range, typically 2-6 grams per 1 lb. (0.45 kg) of cement used. In wetcast mixes, dosage ranges can approach 10% of the cement weight. The ultimate indicator of an overdosage of plasticizer is segregation of the mix. Make test batches prior to production to ensure optimum dosage.
