According to the Fertilome Brush Killer and Stump Killer product label "To kill Stumps and prevent sprouting, apply the undiluted product with a paint brush or backpack sprayer to completely cover the freshly cut surface." For your convenience we have linked the product label in this answer but all product labels are always available on individual product pages on our website.
