OP as you are in the UK, this mare is presumably on muddy fields, stony ground, and if you hack out, tarmacced roads and stony lanes. If she's had shoes on all her life, then her feet have never ever adjusted to going without, and she is probably in a lot of pain right now. You can't just paint on a hoof hardener - if it was that easy then all the TB's in England would be barefoot, and all their owners would be £65 richer every six weeks.
You need to talk to your farrier, listen to him, take his advice. And probably put the shoes back on.
If you want more helpful advice you need to post exactly what work you are doing with her, what the ground is like, what her history is, what your farrier says, and what your motivation for going barefoot is.
Get up, get going, seize the day. Enjoy the sunshine, the rain, cloudy days, snowstorms, and thunder. Getting on your horse is always worth the effort.
