Currently refitting my bathroom and the window has a metal lintel running over the top, i need to fix some plasterboard to it so its ready to be skimmed at the weekend. There isnt enough space to fit a batton so i was wondering what's the best way to fix it up? Google has people saying normal plasterboard adhesive will be fine, others saying it wont, some using Pink Grip and others using Pink Grip Dry Fix. Can anyone suggest how to do this?
 
By design grip fill will work just make sure the lintel is clean. Main issue i could see is getting the board level if the lintel isn't. Plasterboard adhesive will work if the lintel is the type with loads of holes as the adhesive will force through the holes and form a mechanical bond. If it is a solid i-beam/girder type then i would expect it to fail, can flick set plasterboard adhesive off non porous surfaces with ease. If i assume correctly you are boarding the reveals? i would put the top in first then the two sides. Once the skim bead and skim coat is on even if the adhesive fails it should all remain solid and in place provided it isn't a huge span.

In a given situation there are usually several ways of doing things, some work better than others, some plain don't work. Some people swear one is right and the other wrong visa versa this is never more so than the building industry.
 
Thanks guys, ill try grip fill on it tonight. The span is 47 inches. The lintel does not appear to have any holes in it. Its almost a smooth surface with a 15mm gap down the middle of it so i guess plasterboard adhesive wont work. I am plasterboarding the right hand side of the reveal but the left one is pretty much spot on so was going to leave that. I could do the left but it means removing current plaster back to brick to level it with the right so the window doesn't look wonky. I was going to make some supports up to jam the board up whilst it sets starting from top then the right side to give it something
