How to remove of Deep-Set Stains from Porous Tile / Natural Stone / Masonry

Method A

Product Recommendation: Poultice Stain Remover
Equipment: Bowl, household plastic wrap, plastic putty knife and sponge
Coverage: Varies; test first to determine amount of product needed depending on number of stains present

Stain RemoverProcedure:

1. Remove loose debris.
2. Mix several tablespoons of Poultice Stain Remover powder with water in a bowl to form a thick, pliable paste.
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.
6. Remove Poultice Stain Remover without scratching surface with a plastic putty knife and wash off residue with clean water and sponge. If poultice paste has not dried, allow to dry uncovered before removal.
7. Repeat procedure if necessary. If area darkens from absorbed moisture, it should dry completely within 2 to 4 days.
