Hi, i'm wall papering my fire place wall in a paper that is not the same as the rest of the house. I need some tips 4 how to trim down a external corner,so its nice & neat. Ive been told to bend the paper round corner to mark it & then trim ,any ideas please.
Assuming the external corners aren't perfectly plumb and square (have yet to find any that are !)
This is what I've done in the past and you can get a really good result
Get all your lengths of paper cut ready before you start. Lay each piece on the paste table to get the pattern match right - allowing a couple of inches top and bottom for trimming.
The full width lengths on the face wall should be straightforward enough.
Make sure that the 'outer one' is wide enough to go round the corner at least 6 inches so you have plenty to work with. Now cut another length exactly the same. You're going to use one for the face and one for the side. You need two because they are going to be spliced and you'll 'waste' part of each
When you get to the drop for the external angle measure the width required to get from the previous drop to the corner. Call it 'A'
Cut one of the pieces so it's A plus 2 inches from edge joining the previous drop
Cut the other piece so that it's 'full width' less A fron the other edge
Paste them both and soak as normal
Hang the face one and gently smooth it round the corner. If it crinkles, put a few horizontal cuts in it on the side going round the corner so that it will sit flat
Get the second piece and hang it on the side wall so that it overlaps the bit you just wrapped round and has the pattern matching exactly.
Make sure this piece is vertical using a plumb line
Once smoothed down, cut through both pieces where they overlap all the way down with a straight edge and knife
Lift the excess from both pieces then carefully smooth back down.
You should now have a pattern matched perfect corner
