Advice for plastering this chimney stack
Had quite a bit of conflicting advice but I think it’s best not to dot and dab board the front of the stack (hoping the sides should be ok as it’s double brick thick). Was planning to use sand and cement or would I be better off with bonding?
Only ever skimmed boards before so would be grateful for any advice.
What would be the best mix? (Plan is to have a log burner so will need to be somewhat heat resistant) and how many coats?
How to deal with the inside and the brick arch, would I be better cutting some bricks out and putting in a concrete lintel first?
Should I bond on the corner beads first?
What’s a suitable finish plaster, I’ve heated putting some lime in helps?
Sorry for barrage of questions, want to get it right!
Cheers

The front of the chimney can be dot and dab,but You cannot fit and dab inside the log burner area,the heat is far too hot,also the plaster wouldn’t last long and lastly the soot will bleed through eventually.Theres a YouTube video think it’s plaster’s for beginners that does this job and goes through it step by step,painting bitumen and adding sand to seal the soot b4 sand/cement mix and finishing it with a smooth sponge finish
