Lockdown project # 42
have quite a large york-stone patio. Very uneven edges. Planning to repoint it. A guy I know recommends ripping all the old mortar out, using 4 - 1 mix and brush in dry, then sprinkle with a watering can, before pointing
traditional pointing would take bl@@dy ages but time is a commodity I have. The dry method would probably be cleaner though, but I have heard mixed (mainly bad ) reports about this

thanks
I laid a patio a few years ago on the cheap (thin stone) and pointed it using a pointing gun, which was brilliant. I whizzed up the mortar (3:1 or 4:1, can't recall, plus a shot of entraining fluid) a bucket at a time using a big drill with a plaster whisk so that it was nice and squirty (technical pointing term) and injected it into the joints, finishing with a pointing spatula. The pointing gun has a copper nozzle so you can adjust width easily and it doesn't get any mortar onto the surface of the stone.
I was pretty sceptical beforehand but it really worked well.
Much better than brushing in dry mix and sprinkling would be buy a tub of jointing compound, just read the instructions on how to use. If done correctly it will look much better and should last longer
Jointing compound is great and been on my patio for over a year. Did leave some staining on my slabs which faded over time.
I also need to tackle this job.
Is there an easy way of getting all the old pointing out? I have 90 square meters to re point, some of it has already cracked and fallen out, but a fair bit of it is still in place.
I would very strongly suggest looking at Larsen Gunnable Pointing Mortar - amazing stuff and we did a 130 square metre patio with it last year. Durable and easy to work with.
Why not rip out all the old stuff and let herbs grow in the cracks?

I’ve used this joint compound on a few jobs and it’s fantastic, lasts a long time great finish and very easy to apply
I’m thinking of using sika fastfix, any one used this?

Really good suggestion. Plant some creeping thyme, then every time (sorry) your feet brush against it you get this wonderful scent.
I used Joint It resin wet brush in on a patio myself and Mrs Rex laid a few weeks back. 200 x 100 sandstone setts laid on sharp sand, they laid flat but rotated sideways fairly easily. The jointing stuff is bloody witchcraft, locked them all together with minimal effort and looks great. Hope it lasts well
