Their mosaics are coated in a water soluble glue. Thinset will not adhere to the stone, there is a water soluble barrier. Was originally told the adhesive was a non-water soluble resin. Glue broke down in 45 minutes when subjected to a 24 hour water submersion test recommended by Laticrete. Will not use this tile as it will not last long-term, only as strong as its weakest part, water soluble glue.This is true because the cement in the setting system sets up and adheres to the mosaics before any deterioration of the water soluble glue can occur. - Bob Agran, Stone Partnership Inc.

I work for a distributor for Stone Partnership and am always in awe with their above and beyond customer service. Whether it be 500 square feet of a Veincut Travertine or 20 square feet of a marble mosaic, they always go above and beyond to make sure the project runs smoothly.

They wont sell to you unless you are family, close relative or friend. They have this nonexistent network of distributors they refer you to that dont even know who Stone Partnership is. They wont sell to you direct. And you cant buy from their distributors.
