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. It is often used when building a completely custom mix design. If using a Buddy Rhodes blended mix or admix, it is more common to use a product that is strictly a plasticizer such as Water Reducer 310. 420, or 555. Adding Water Reducers will increase workability of concrete mixes that have a low water to cement ratio. Maintaining a low water to cement ratio is critical for reaching optimal strength in the cured matrix.
Water Reducer 205 is 10% as potent as Water Reducer 310.

Dosage
Dosage Rate: 0.5 - 10% of cement weight dosage. Rates will vary depending on the materials used, mix design, ambient conditions and the requirements of a specific project. Make test batches of 5-10 kg of concrete until you are familiar with Water Reducer 205's effect on your mix. In GFRC face coats, use the lower end of the dosage range, typically 2-6 grams per 0.45 kg of cement used. In wetcast mixes, dosage ranges can approach 10% of the cement weight.
Caution - do not overdose water reducers. The ultimate indicator of an overdosage of plasticizer is segregation of the mix.
