Hanging Wallpaper Top Tips
When you buy your wallpaper ensure that an extra roll with the same batch number will be available. Otherwise, if you need to buy more you may end up with a roll bearing a different batch number and the shades of colour may vary.
Wallpaper should be hung on a sound, even, dry surface. Very poor surfaces may need replastering; alternatively, you may just have to line or cross-line with lining paper.
Establishing a Vertical
Once you have decided on a starting position, you need to establish a vertical so that the lengths of paper are correctly aligned.
Measure out from the corner of the wall a distance that is 1cm/1/2in less than the full width of the paper, and mark it top, middle and bottom.
Hang a plumb line from the top of the wall aligning with the mark nearest the corner and mark along it at intervals. Loin up the marks using a straightedge. This pencilled line is the vertical you will use for aligning the first length of paper. The same process must be repeated each time a corner is turned.
Some wallpapers are available pre-pasted, but if you are pasting the paper yourself you will need a trestle table or a folding pasting table on which to lay out lengths of paper. To avoid getting paste on the table and the consequent risk of spoiling the next length of paper, some decorators let the paper overhang the table by 2cm/1 in, but it can be difficult to paste edges if they have no support. Keep a clean sponge and water on hand, and wipe away any paste which does get onto the table.
Most papers need to be left for a while to allow the paste to soak in. Papers with definite patterns should be pasted and hung one length at a time, so that soaking times do not vary — a length left for too long will stretch irregularly and may not match the previous one.
Materials and Equipment
• rolls of wallpaper: buy enough for the job, and record the batch number
• wallpaper paste, as recommended by the manufacturer
• pasting table
• plumb line and bob
• paperhanging shears
• sharp-pointed scissors for trimming
• pasting brush and bucket
• paperhanging brush
1. Apply paste down centre and work outwards. Fold pasted end in and paste second half.
2. Fold paper ends-to-middle and carry to the wall draped over your arm. Turn over ends of paper.
3. Position first length against pencilled vertical, overlapping the ceiling by 5cm/2in and running to about 1cm/1/2in from the adjacent wall. Brush from the centre out.
4. Score along the ceiling line with the back of the scissors, peel back paper and cut along crease. Brush paper back in place and repeat at skirting level.
5. To turn an internal corner, measure the distance to the corner at the top, middle and bottom of the wall, adding 1cm/ 1/2in to the widest distance to allow for overlap. Cut and paste in position. Measure width of offcut from corner and mark vertically this distance from the corner onto the side wall. Paste the offcut, aligning the uncut edge with the vertical line so that the cut edge covers the overlap.
6. To turn an external corner, measure the distance to the corner at the top, middle and bottom, adding 2.5cm/1in to the widest distance to allow for turn. Paste in position but do not brush down. Mark a vertical (using a plumb line) 2.5cm/1in less than the width of the remaining piece on the adjacent wall. Hang offcut to vertical line, and brush overlap down.
7. To paper around a doorway, cut away any excess before pasting and make a diagonal cut into the corners of the door frame. Score around the door frame, peel the paper back and trim. Brush in towards the angle.
