Questions & Answers

Have a question about this product?
Can I spray a small area, leave the rest on the shelf for a few weeks/months, and then use the rest at a later date after I think my trial is complete? Or does this need to be used all at one time?

I've never used hose-end sprayers before, and I initially intend on testing this product out on a small area for a trial application.Thanks!
