Crooked Drywall Seam?

[Kirkwa]

Hi, new here and hoping someone can help. I re-dry walled my upstairs bedroom, and both sides of the room has hip-walls. I finished the drywall seam between the hip wall and the slanted wall. Unfortunately, the seam is wavy. Is there anyway to fix this with out pulling off all the drywall mud and tape? A tool, perhaps, that works for whatever that angle is to get a straight line?

Thanks, any help would be much appreciated.

I take it by hip wall you mean something like this?
If the plasterboard edge isn't straight then the tape wont be straight either, it just follows the line of the gyproc. If it looks bad, why not 'round' the edge rather than trying to get a neat straight line?
I'm sure Belmore tools do a 'bullnose' knife

As EK says its very hard to get a straight line if the boarding isnt spot on, Im guessing you have a flat bit of ceiling inbetween the two slopes, I think your only option is to round them off which is ok as long as you dont want to paint in different colours. If it has not been taped all ready you can use metal angle bead instead of paper or scrim to get a straight line but you still need good boarding.

Use one all the time,complete ghod send.Painters hate them though,as they can't cut a line in the finished seam if ceilings and walls are different colours...hey oh,it helps to cover a multitude of sins though...

cracking tool - last count sold over 1000 of these ! all over Europe, best tool for this kind of job/application - have seem a few other ideas for inside off angles but none that work as well as the flexi knfe

There is nothing as unprofessional as a rounded corner. If the sheeting is poor, just invert a flex tape or if it's reallly bad, use no-coat or something wider. I have two of those spankers, one I have sharpened so it leaves a proper corner, the other I don't use. Sharp lines everytime on my jobs.

I prefer a sharp line too Tony but sometimes rounding it is the only way if the sheets are all wavey davey

[belmoreboy]

im sure we sell more to plasterers than jointers, with you both on the sharp lines but as Ek says boarding needs to be good and often out of the tapers control - new levelline tape is good alternative

What's the new levelline tape Marcus??
