Re: garage refurb
I never built a chimney either.
I used type S mortar between the blocks. I set the liners in and fille d the area between the blocks and liner with sand. The chimney block I used, has holes like a regular block, I filled these holes with concrete. I also added two pieces of rebar as an extra tie together to make it more solid.
We enjoy sitting on the deck watching for bats to circle around. Well, we did until one swooped down when my wife and daughter were sitting by the lake one evening
Never built a chimney before, did you do anything special to the blocks or just mortar like bricks and fill with sand?
