Hi 2 Balls got to agree with what you say, ime into old school work myself worked on lots of old buildings over the years with a 5 year stint on a country estate cant remember exactly now but something like 10 farms and 200 houses between 1500ad up to Victorian but most were Georgian and many were listed, and of course my 200 year old house in Spain.When i did my tiling course in Australia in 1981 the first 2 weeks were tiling with sand and cement when i asked the instructor why we were doing this, dont get me wrong i was realy interested, he said this method will get you over the worst wall you will come across which is quite correct, a couple of times over the years i have come across situations where i could have done it but up till now i havent now looking for the next opportunity to give it a go just to prove i can still do it could be years though till i get a chance.
