Lay hearth first or the inner fireplace?

[GoodOne]

Hiya,

What would be best? I've opened the fireplace and removed the hearth as to replace with the new one. I want to install a vermiculite board (brick effects) on the inner wall of the fireplace and also the new hearth. So which should i start first? The inner wall or hearth

It'll depend on your skills really. If they're good, then do the hearth first, and then cut in the vermiculite boards. There's no right or wrong way for this job, so don't worry about it.

Anyone knows if the vermiculite board (brick effects) is paintable. If it is, do you have any picture of it, which you have done it before? Thanks
