This is our fine powder gypsum. This product works best when scooped and put directly on the brown urine stains covering them in a thin layer. Once moisture is applied it will break down and work into the soil. This will open up the soil and allow moisture to flush the urine. It will loosen the soil back up and allow grass seed to grow again. It can be applied as needed as long as moisture is available.
