Thanks Sorry I did wet the wall, but I was very new to RU-vid at the time and forgot to film it.. thanks for watching I hope you enjoy the channel Regards Brett
Well executed but 3:1 is too strong (pointing is a sacrificial material) and the style of pointing too bold and does not suit stonework at all. If any would-be pointers require reliable technical guidance on repointing, do take the trouble to read the Building Research Establishment publication “Good Repair Guide No 24” (Repointing external brickwork walls) as this provides authourative information, including clarifying suitable mortar mixes, warnings of when worn pointing affects structural integrity and the importance of using lime pointing on old solid walls.
I agree - as a 67 year old surveyor I am still learning (not too much doing these days) and only discovered the wonders of lime mortar approx 5 years ago! Yes do have a look at that pamphlet as its only 4 pages long and a bargain at about 10 squid.
I'm not entirely convinced on your ''good repair guide 24'' I've been a bricklayer for 38 years, originally from NZ but served my time in London from aged 20. Back then we were taught pointing mortar was mixed 3:1:1 sand, lime and cement. Never let me down anyway, never a call back and at my last trip to London, went back to the builds I was involved with and still great work to look at and structurally sound including the weather cut n struck. In terms of your comment ''pointing too bold and does not suit stonework'' , this is entirely opinionated. What I would have done here, is a few example panels for the client, weather flush and bagged, recessed, concave/convex or weather cut, let the home owner decide. One other thing, ''(Repointing external brickwork walls)'' - this is not repointing, it's new pointing. Looks OK to me well done mate
If sandstone best with nhl or natural vicat cement. As quicklime hydrated lime on certain sandstone studues shown erode it. But if not sandstone, then use lime on wall. If cement blocks nhl, cement with some lime for movement crucial. I think ppl need to study materials, properties, studies, and real live study shown after yrs of materials used the damage or goid irs done over time, as cement erides alot natural old school brick etc. We all need re-educating, im still learning.
3:1 was how my dad showed, but I know there are a lot of different schools of thought, perhaps 3:1 is pos too strong. A builder friend of mine uses 5:1. I did actually film that vid with my old camera that might explain the sound issue. Anyway mate thanks for watching. Take care Brett
Sorry mate I actually did wet it down with the brush first. But for some reason it didn’t record. And because I’d already done the pointing I couldn’t re record it. But it’s a valid point my mistake. Thanks
Sorry mate no I don’t, it’s not something I do very much these day. I thank you watching though and next time I need to point anything I’ll be sure to make a video of it.
