Dosage and Handling
Building Mortars: GOODPOLY PD303 is added to other powdery components and mix to get a homogenous formulation. The dosage may vary from 0.05%-0.3% of the total dry material by weight.

Clearance: add directly or add to mundificant, s est dosage may vary from 0.1%~0.5% of total formulation by weight.

The actual required dosage should be evaluated in suitable tests prior to final application.

Storage
GOODPOLY PD303 may be stored in sealed bags for at least 12 month. The storage temperature should not exceed 35°C. It will remain safe to use for a longer period of time. However, product quality has to be verified by appropriate tests then.
