Hand mixed mud vs. bagged mortar for small jobs, which side are you on?
I got into it with a guy on a jobsite last week over this. I was doing a little repair on a chimney in Fayetteville, maybe 50 bricks worth, and I just grabbed a bag of pre-mixed mortar from the lumberyard. He shows up with his wheelbarrow and starts mixing sand and cement from scratch, saying the bagged stuff is too weak and won't match the old lime mortar. I get his point about strength, but for a quick patch I swear the pre-mixed sets up fine and saves me 15 minutes. I used it and it's held up through a few rainstorms so far, no cracks. What do you guys do when you're just patching an old wall? Do you stick with the traditional mix or take the easy route with bags?
