This project for JD Tile consisted of working with an architect, the customer! His vision was to use chalkboard slate slabs previously used at an old schoolhouse. He bought the slate at an auction. Each slab of slate was approximately 4′ by 4′ and some larger. Each piece had to be cut and dry fit before installing it. Waterproofed the shower with kerdi waterproofing. The shower pan is a kohler cast iron pan. A piece of slate was put on the ceiling as well. This project was framed out by the customer years ago, he needed an installer who had experience working with slabs. I worked on a large slab installation back in 2009 on the Lancaster Convention Center/ Marriott Project with other subcontractors putting 3 mm slabs in. The customer found JD Tile through the John Bridge Tile Forum where Jon is a professional advisor. He is always looking for uniques projects like this most installers are afraid to take on because they have not worked with slabs. The architect customer incorporated a unique idea bringing the wall out to create a shelf.
This material was about 3/8″ in thickness. Tuscan leveling system was used to insure the joints were flush. Laticrete 317 thinset was used. Mineral Oils are going to be used on slate to condition it.
