Small DIY plastering

ryan7

Currently decorating a bedroom.
There is a crack were the plasterboard meats the chimney breast that stretches from floor to ceiling. 
I'd like to DIY rather than the expense of a plasterer.
Can anyone recommend a mixture that can be applied and smoothed out to a satisfactory finish?

Photo, please. And is the surrounding plaster firmly attached? When you tap it, does it sound solid or hollow?

It depends on the size really. A pic would be helpful. Toupret or easyfill are both easy to sand smooth though. Buy the powdered versions rather than ready mixed if you hae a fair bit to fill.

The area either side is firm and place. 
The crack had previously been ames taped and the previous owner had 2 layers of wallpaper. 
When steaming and scraping off the ames has peeled away. 

Currently at work so can't send a picture.

I usually fill the crack first. Then use a lime based joint filler. First a thin skin of filler and then tape and leave to set. Then 2 or 3 more thin coats of filler.
Then a light sand.
You can also use a fast setting filler.

Depends on the size, if it's just a small gap caulk will probably do it. I use external caulk for hairline gaps because it has more flex
