Stone/thinset on a painted wall?
I bought some stacked stone for a backsplash installation. From the manufacturer it's recommended I use a latex modified thinset. However my kitchen is finished and painted and they also said I should only adhere to backerboard. I've seen on multiple sites that in this situation people rough up the wall by sanding so it adheres better. I want to do it the right way but I dont think I can get a refund on this. At the same time I can't have stone falling off my wall in a year.. Can anyone shed light on this? Thanks for reading.

The best option is to remove the sheetrock and install Hardi Backer or cement board. If you install the stone over a painted wall I would definetely give the painted surface a aggressive sanding to help the thinset adhere better.

I have done several stacked stone projects at current house. Outside installation requires cement board or screen & scratch coat along with proper water proofing. Indoor is less critical.
My stacked stone fireplace surround, 6' tall x 10" wide is installed directly to the drywall.
The minimal amount of material on a backsplash is not going to be much more than a conventional tile install.
Rough it up, add some more screws to the studs is all you need to do!
