Can I Spray Water-Soluble Granules?

Modified on Wed, 8 Jul at 4:37 PM

In most cases, yes. Water-soluble granules (WSG) are generally compatible with battery-powered sprayers when mixed and dissolved according to the chemical manufacturer's instructions.

Using WSG Products

To achieve the best results, and to help prevent clogs, there are several best practices to keep in mind.

1. Fully Dissolve The Product

Always ensure the granules are completely dissolved before spraying.

Follow the mixing instructions on the product label.
Add water and WSG in the order recommended by the chemical manufacturer.
Agitate the solution thoroughly before use.
Allow adequate time for dissolution if required by the product.

Undissolved granules can settle in the tank and potentially clog filters, nozzles, or plumbing.

2. Keep Filters Clean

Water-soluble granules can sometimes leave behind small particles or residue if not mixed properly.

Inspect and regularly clean:

Tank strainers
Inlet filters
Nozzles

3. Agitate The Solution

Some WSG products may settle over time. If your application lasts an extended period:

Periodically agitate the tank mixture.
- Physically shake the tank or spray into the tank using the spray wand.
Follow all manufacturer recommendations regarding agitation requirements.

Required Cleaning Procedure

After completing your application it is crucial to thoroughly clean the sprayer to prevent residue buildup.

Empty any remaining solution.
Rinse the tank with clean water and soap.
Flush the hose, wand, and nozzle.
Clean the inlet filter and any strainers.
Store the sprayer properly once it's clean and dry.
