Pci adhesives for limestone

[jonnyc]

anyone using pci adhesive for fixing limestone.
i need an adhesive that gives me time to bed stone and adjust courses and also does not have staining problems.

you have less chance of staining with a rapid set adhesive, imo

I'll second that. Rapid set flexible would be my choice.
