Render on top of Bath stone capping?

Anonymous user 9 March 2024 - 3.28 PM

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.
