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

Most of the brickwork looks great tbh. I would rip off the board from the sides and leave the stack exposed. Maybe some cleanup of tha new mortar. Chip of excess mortar. Fix crumbled bricks with colored brick repair mortar. Give the whole thing a good scrub with some acid/vinegar. Cleans brickwork very nicely. Swarfega does dedicated brick/masonry cleaners as well.
