Repairing bathstone

We have a listed grade 2 house built in 1850's. Over the years previous owners varnished and painted the internal bathstone windows (all 9 of them) . I have painstakingly worked on getting this off (so far done 3). There is damage, not just on the joints but all over including the top curves. How do I get a really nice repair finish without it looking bodged??

"Depending on how bad the damage is you may need to
replace stones or get an indent repair done.
If the damage is minimal you could get away with using
bathstone mortar repair.
Do you have any pictures you can send?

"Hi Martyn,

You would have to restore the mouldings and other detail of the bath stone with restoration mortar, this being lime based, please do not use cement based products as this will suffocate the bath stone, in turn decay will occur..

We are a specialist restoration company and can help if you need.

Hope this helps

"You will require some pre-mixed bath stone and some prep on stone prior to repair, I would recommend a stone restorer ( like myself ) is asked to quote or you could indent with natural bath and shape but again professionally done"

"sorry but if you aren't skilled at this it's never going to look like it's meant to but you grind it back to the original bathstone rub it with sandpaper hand chisel the corners cut out all old joints and square off the repairs then mix up your bathstone pre-mix and fill them have a bucket of clean water with a new sponge and its the sponge that gives it the finish you need i hope that helps you but it is a hard job if you don't know what your doing good luck"
