This is the eco-friendly mulch colorant that revives the appearance of faded, timeworn woodchips. It enables an amateur landscape architect to acquire the aesthetics of a newly manicured lawn or garden with minimal effort. Simply mix the stain with water inside the unit’s one-gallon tank, prime with air pressure via the built-in hand pump, and apply to unsightly discolored woodchips using the spray wand. The application dries in three to four hours, lasts up to three months, and is non-toxic to pets, plants, and children. Includes one 8 oz. bottle that covers 600' sq. Black forest, Sierra red, or Cocoa brown. 13 1/2" H x 7 1/4" Diameter. (4 lbs.)
