How to use this result
A planning quantity, not an instruction to pour.
Use the label’s application method, protective equipment, maximum dose, spacing, and re-entry directions.
Never combine chemicals. Add one product at a time with circulation as directed.
Start with the staged amount, allow the label-directed circulation time, and measure again.
