Problem with Jura blue/grey limestone

[jonnyc]

Just fixed a 60 sq mts floor Jura blue and after twelve days drying stone has a cloudy/patchy background which client does not like .done a wexa scrub and got lighter but not completely gone.used rapid set . Not sure what more I can do. I have had this problem before and think it is mineral content and am sure that over time the stone oxidises and turns brown .just wondering if there is any miracle cure to get rid of cloudiness.

not sure Jonny, I have had some rust spots develop on jura in the past but the clients have been okay when the supplier explained it can happen sometimes

Was the substrate totally dry before you you started tiling. This time of year stone will take a lot longer to dry out after you have fixed it, grouted and washed it down. How long did you wait until sealer was applied?

Have noticed on drying some veining becomes more pronounced.

Gary.i have seen rust spots grow from 5mm to 100mm over the period of a month or two.you can see how the ring has eminated out from the core spot. This is not the same .think I need to post some pics
