Hi all! Advice from tradies or experienced DIYers welcome. We have renovated and removed wood shelving around an old fireplace. That has left unfinished edges as you can see in the pic: https://cdn.geekzone.co.nz/imagessubs/eb68c2f8c5eb84573002313ee42ea877.jpg

I need to plaster/fill this but am not sure what product/technique to use.

The unfinished sides are quite deep, and in some places the plaster I add will be up to 25ml thick.

The area doesn’t get hot at all.

Any tips of what product to use/unique?

The areas aren’t that visible, so the finishe doesn’t need to be perfect. We are going to paint over it.

Cheers!

I think you'd find attaching a strip of wood down that side would be a lot easier.

I am literally doing this at the moment with mine.

We wanted a smooth finish, so used cemix mortar patch to adhere to the brick (wet the bricks with water first - a spray bottle is good). I then have been using plaster mix to apply a smooth finish.

Thanks, what we want to fill is not the brick fascia, but the edges where you can see some polystyrene stuffed in. Is that the same as you are doing?

We have an old double brick house and were advised to skim the bricks with mortar to increase adhesion of the plaster. Also 25mm will need three coats of plaster minimum (10mm max - and it is hard to do it that thick). Found that it is slow to dry on the bricks - ie. 3 days.

Looks like there is pinkbats in the corner. You may want to spray some expanding foam over it (push it in a bit), which you could plaster against.

Question is where you want that side face to be brick finish or flat (my advice assumes flat).
