3. Apply a 1/4″ (6 mm) thick layer of paste directly over stain with at least a 1″ (25 mm) overlap beyond edge of stain.
4. Cover with household plastic wrap, taping around perimeter to seal over Poultice Stain Remover mix. Leave a small section untaped or punch holes in plastic wrap to allow for slow curing.
5. Allow paste to stand on stain for 24 to 48 hours.
