Render on top of bath stone capping?
Hi... I have an old sandstone garden wall which was capped with what I believe is Bath Stone (we are only about 30 miles from Bath) approximately 5" thick. It was constructed back in 1898. The surface of the capping has long gone and prior to me moving in I'm told a simple cement render, maybe 1/2" or 3/4" thick, was put on top of the badly eroded capping (2 or 3 times over the years I'm told). Each time the render has eventually cracked and broke free taking a little more of the original stone with it. Is there a means of rendering this capping so that it better matches the original and will last for more than just a few years? I've been looking a K-Rend on top of a mesh of some kind with a water-proofing additive - would this work? Thanks in advance.

You should use a bath stone premix which is readily available From places like Apex Grange
You should not use a sand and cement Renderer or Krend as this will eventually crack and Peel away where as Bath stone premix will last a lifetime

Replace the stone and forget the rendering
