Normally buff stone does not require seasoning beyond the usual sixty to ninety days quarrying, sawing and fabrication process. For best immediate color uniformity, gray stone should be seasoned a minimum of six months prior to setting in the wall. This allows the organic matter in solution to stabilize. The organic matter will oxidize upon exposure to the elements causing gray stone to lighten in color with age. Due to the seasonal nature of the quarry operations in Indiana, it is sometimes necessary to use unseasoned stone. This is an approved practice in the industry; any resulting discoloration will disappear, usually within a few months after the stone is set. To mitigate the potential for staining, the use of gray stone in interior applications should be limited to fully seasoned material. Although ILI and its member companies urge contractors not to use the limestone shipper’s celotex or similar pads as separators for long-term storage, this practice occurs. It can result in comparatively long-lasting figuring of the stone, especially in the case of stone containing quarry sap. Although most of these “pad marks” will ultimately go away by themselves, and can usually be removed with special efforts, stubborn marks occasionally remain. It is much easier to avoid this problem by using non-absorptive spacers which allow air to circulate. ILI or its member companies will be happy to comment to inquirers on the subject.

I was just trying to find the website and I was on the IL IA or Indiana Limestone Institute of America. No luck.
Can you give me the URL?

I was just asked to address staining on Indiana Buff limestone. These are exterior panels and have been up for 3 weeks. However, before instalation they sat outside in crates for a month. The stain looks like moisture to me however I'm not sure if the packing materials could have transferred into the stone some? I was thinking about testing a panel with a poultice tomorrow. I also think that finally having warmer spring like temperatures may dry these panels out. The panels are honed.......possibly around 400 grit finish. Pretty smooth. I will also mention that the installer tried power washing and failed. Thanks for your input.
