Mosaic clawfoot tub?
I am a first time poster on this forum, but a long time lurker and learner.
I have an old cast iron clawfoot bath tub. I was hoping to mosaic around the outside of it and use it as a feature planting bed in my garden. It would have to stay out in the elements during our Canadian winter (temps dip to about -20 degrees celcius with lots of freezing/thawing cycles).
So my question is - Is this do-able? Would I have to use special tiles, adhesive, grout, etc? Any special preparation to the surface before tiling?
Any advice would be greatly appreciated.
