Re-pointing tips

[specialbranch]

Hi Chaps, Ive got a job coming up in May to repoint 150m2 of Marshalls Heritage Paving. I do a lot of remedial works for a Large Installer, and im looking for any tips on grinding out the old Mortar. We find this the slowest part of the job. At the moment we just run the Stihl saw down the joints then chisel them out with a flat headed screwdriver. Anyone know of a better way, or special tool that can be hired. We were thinking of trying an industrial vac to clean the joints out quickly once the Motar is loosened? Im told the pointing is pretty good/solid but the client asked for flat pointing and its been round pointed. Cheers Chris

indeed it is slow m8
i use a diamond blade and try and cut at least 40mm down then as you say carefully chip the sides into the void
Then use a henry hoover to get all the crap out
the hoovering is also slow
i think it took me and a lad 6 days to do 60 m and only 1.5 days of that was pointing,the rest was removal and cleaning

You can get a mortar-raking blade - wider than a standard diamond blade, so it cuts out more of the jointing in a single pass.

Nasty, nasty, nasty work!
