For a typical open top grain (dump) truck, Protect-It® can be applied by evenly spreading the material over the surface of the grain mass and then raking it in to prevent it from blowing away. As the grain is dumped from the truck and is conveyed into the bin, the Protect-It® mixes well with the grain.

General Information

Protect-It® can be applied both wet and dry. Wherever possible use Protect-It® dry – it will work faster that way. Since Protect-It® is a very fine powder it disperses quite easily. This means that in the case of structural application, Protect-It® can often be applied at one access point in the bin, e.g., upper hatch, lower main door, and it will evenly cover the ceiling, walls and floor of the bin.
