Zinc sulfate is toxic to fish and other invertebrates.
Things You Will Need
-
Put on safety gear, including work gloves, a breathing mask and safety glasses.
-
Pour 3 gallons of warm water in a plastic 5-gallon bucket. Do not use metal — the zinc may react with metal items.
-
Add 1-1/2 lbs. of zinc sulfate powder slowly to the water to avoid dispersing the powder in the air. Stir it with a disposable painter's stick to mix it thoroughly.
-
Pour the zinc sulfate solution into a garden sprayer. Attach a garden hose to the sprayer and apply it to the roof.
