Hi there all,
Thanks for all that fantastic information.
So i started off with hammer and chisel and some of the cement just dropped right off. However, this house has been “restored” twice and the second “cement restoration” was around 2006 some of the cement is not coming off at all!! Its all been done higgeldy piggeldly style on the one particular wall that i have set my heart on doing. Its the dodgiest wall, by which i mean the cement is falling off in places so i figure that this will be the easiest one to fix. So i found my ex’s drill thing and i am just going to drill it off gently, and if that’s not possible well then i will get if off one way or another.
Behind the pieces that fell off, there was, lo and behold, the infamous dampness. So i will do my best to knock it off, clear out the cement grouting and let it dry.
There are some good youtube videos showing guys mixing lime mortar. Looks all kind of fun. Think i will go for the re-pointing, as rendering just is not my preference.
The other 3 walls of my house are a nightmare that i will not be touching at all, they all have recent thick looking layers of cement and it really looks like too much to deal with, in spite of the humidity issues.
Looking forward to my one wall project!!!
Thanks for all the info, its been extremely informative.
I shall no doubt be back with more questions at a later date!!
Cheers folks. Good night and good luck.
