Hello all,
Looking for a bit of expert advice with an external wall I'm debating repointing in my flat as I'm getting a fair bit of rain water in around the windows. I've not attempted it before so apologies if the questions seem a bit novice-y. My building was built in 1903, so I believe I should be using lime mortar rather than cement.
Should I be using hydraulic/non-hydraulic lime mortar? Its bloody confusing! From reading around I suspect NHL 3.5 but I'd rather be sure. My flat is on the top floor, located in Clapham, London so isn't subject to huge amounts of water. I've no idea what type of bricks they are but they seem like pretty standard small red ones!
Also, as I'm top floor and don't really have anywhere to mix, would the easiest option to buy a bag of ready made lime mortar? If so, would it be available from standard builders merchants?
Any help greatly appreciated!
Cheers
Jim
