Wallpaper 101 - How to hang wallpaper

In this handy guide we will show you the basics of hanging wallpaper! Once you have prepared the walls, put on your lining paper, if that was deemed to be necessary, assembled all the items and tools you need for the job, you are ready to start hanging the wallpaper that you have chosen.
If that wallpaper has an all-over pattern then you should begin at a window, working away from it in both directions towards the darkest corner of the room.
If your choice has fallen on a large patterned paper, then it should be centred on the chimney breast.
You may have a room which has two adjacent windows, in which case the covering should be centred between them.
Having decided on your starting point you should then use a plumb line or spirit level to mark two vertical lines, one each side of the window.
Unroll the wallpaper with the pattern side up; measure the drop between the ceiling and the top of the skirting board, add a little for trimming and cut your first length. Then cut a few more lengths, making sure that the patterns match. Put all the lengths you have cut on your pasting table, making sure they are pattern down, then use a pasting brush to paste the top length, starting at one end and working from the middle to the edges. As you paste, fold the paper into a loose concertina – but be very careful not to crease it.
Unfold the top half of the first length and press it carefully at the top of the wall, allowing roughly 50mm to trip at the ceiling, and use a papering brush to smooth it into place, matching the edge with the vertical line you have drawn and being careful to remove any air bubbles which might have formed.
Having done this, use the end of the brush to flatten down the paper where the wall meets the ceiling and skirting before trimming the excess, easing the paper away from the wall to cut with scissors. Then gently brush the paper back into place. Hang the next length loosely from the top and butt it up to the first length, making sure that you do not have any overlapping, match the pattern, and smooth into place.
Carry on in the same vein with subsequent lengths. Corners are more difficult. What you should do is paper into the corner, allowing a 20mm overlap round the angle. Never try to work a length around a corner because most walls are not square.
Follow the step by step guide and you will be left with a wall-papered room of which you can be rightly proud.
