I got quoted 500 for about 5 meters of wall at standard 2300mm height. I’m chewing it over as I can get it all done in a day and clean up opposed to a couple of hours on a 24l tank and multiple clean ups.
Can anyone who’s cleaned up natural stone walls of mortar suggest a better way than sandblasting? it’s creating far too much dust.
its 100 year old ash mortar btw.
