Check that all rolls have the same batch/shade number, open and examine in case of colour variation. Should any fault be apparent STOP IMMEDIATELY. Always keep all roll labels safe until your decorating is completed, these will always be required should a problem occur with the product.
It is essential to read the manufacturer's instructions before commencing the job and to take particular note of any recommendations regarding the pasting of the wallcovering.
Always follow the manufacturer's hanging instructions, these may differ from what we are going to state below and should override what we say, below is only the typical wallpaper hanging technique.
As a starting point you should aim to cut enough lengths to complete your first wall (or your feature wall).
Measure your skirting to ceiling height with a tape measure, note this information down, you can now prepare to cut the first length. Refer to the roll label to check the pattern repeat and pattern match for your wallpaper.
Open the roll out onto your paste table with the pattern facing up, establish the correct way the wallpaper should be hung. If necessary, refer to any images available online or contact the staff and we can help you.
Measure the amount of wallpaper needed for your first length using your tape measure, a quick check to see if you need to balance the top of the pattern (by sacrificing the first few centimeters or inches of the roll) to make sure you are not cutting through an important component of the pattern at the ceiling.
Make sure you allow yourself an extra 10cm / 4” for trimming on each length (5cm / 2” at each end) and cut your first length with a snap off knife or fold and cut using scissors. This will allow for changes in wall height across your wall.
Now you have your first length done, you can prepare your second. Grab your roll and open out an arms length, with the pattern now visible place the roll parallel to your cut length. Move your roll along until the pattern matches and flows across both lengths, you may need to open up the roll a little more to get the pattern to match.
Once you have done this, slide the roll across onto the cut length (keeping the position where the pattern matched) and set this down.
Make a crease at the top of the length to match the size of the excess given to the previous length, fold this crease on to itself and continue to open out the roll on top until you reach the other end of the previously cut length.
Making sure the lengths now match in size, make a crease along the bottom of the roll and cut this free from the roll. Return to the top of the length to trim the surplus from your first crease.
You've now got two lengths cut, to keep these in the correct order of hanging by numbering them in pencil on the reverse (at what will be a top edge).
Repeat this procedure of matching the pattern against your previously cut length, creasing, folding and cutting until you have enough lengths to complete a full wall.
As our walls are not always truly square into each corner, we need to mark a starting point that will make sure each length of wallpaper is hung straight. This procedure should be repeated each time you start to hang wallpaper onto a new wall.
Using your tape measure, extend it to 45cm away from your first corner and mark the wall (at the top) to show this point.
Now it’s time to use a plumb bob and line, this weighted line can now be held on your mark and once the line holds still you should make further vertical marks down the line. If you will struggle to see these marks, join them up using a straight edge/metre stick or batten.
When we come to hanging we will work from this line across the wall and back into the corner.
Now you’ve got your lengths prepared and the wall marked up you are ready to get pasting. If you’ve never mixed paste before, read this first. Some wallcovings are not compatible with a flake paste and require a ready mixed adhesive. Check this prior to application.
With your lengths now cut and waiting on your pasting table, they need to be flipped over with the pattern side facing down. As you have cut them in order remember to keep them in this order.
Paste the first sheet by spreading some paste or adhesive into the centre and working the brush in a herringbone pattern to spread evenly and to reach the edges. A good technique is to hold the paper against the table edge furthest from you and paste up to this edge first. Then slide the paper towards you and paste the nearest edge. Try to always work cleanly and don't allow paste to get on the front of the wallpaper.
Once you have covered the reverse of your wallpaper, fold the pasted sides inwards so that no paste touches the face side (pasted side to pasted side). Once pasted and folded place this length to one side ensuring the soak time is adhered to (this is noted on the roll labels), by allowing the wallpaper to absorb some of the adhesive it will become more pliable prior to hanging it.
Working safely and using any ladders or steps properly we can now begin the wallpaper hanging. Peel back the two pasted surfaces and find your pencil marked number from earlier, this will show you whats the top of the length.
Open out the first side of the wallpaper when you are safely in place at your wall, lightly press the top of the first length against the wall, with a 50mm overlap at the top.
Allow the opposite side to run around the corner of the wall as you smooth out the wallpaper, this will be trimmed later.
Slide the edge up to the vertical line made earlier and use a smoothing brush to get rid of air bubbles, keeping the edge of the length against your line.
Always use herringbone strokes from the centre of the length to smooth out the bubbles, working from top to bottom.
Once you are half way down, you will now need to unfold the remaining portion of your length from being unfolded upon itself. Again keep this to your marked line as you complete the application and smoothing.
Trim the top and bottom of the length by creasing the paper into the skirting and ceiling/picture rail with the back of the scissors. Cut along the crease. You may be able to use a clean and sharp snap-off knife for this however you may find it snaggs on some wallpaper types, if so? Return to scissors.
Don’t forget to trim off the excess wallpaper that ran around the corner, keep this as neat as possible using the above techniques.
Hang the next length in the same way, this time butting the edge neatly against the first piece hung, lining up your pattern correctly as you go.
Make sure these edges are firmly glued down by running a seam roller along the joint, refrain from applying too much pressure as this will push adhesive away from the edge, wait about 10 minutes to push down edges for a better result.
Always sponge off any excess paste with a clean moist sponge or the paste will dry as a shiny patch.
A lighter touch, damp cloth and a dabbing approach may suit some wallcoverings better, check the washability rating on the label.
Repeat the above procedure for each cut and pasted length, ensuring that the edges meet exactly and the pattern is matched.
Wipe over any excess adhesive left at the ceiling/picture rail or at the skirting boards before starting a new wall as this will have dried before you get back to it.
For internal corners, measure from the last full width roll to the corner and add 15mm. Paste this cut length to the wall and press the small overlap piece around the corner. Overlap this piece with the next length of paper, using a plumb line for accuracy.
For external corners, use the same technique but allow about 25mm overlap. Hang the first length on the new wall so that it is about 12mm from the corner.
