Prepare 

Step 1: Make sure any holes have been filled and sanded and the wall has been cleaned with sugar soap.

Plan

Step 2: Starting at the centre of the wall mark roughly where each length of paper will hang to ensure you have enough for any internal or external corners. 

Step 3: Locate your middle marking and use your spirit level and a pencil to draw a vertical line from the top to the bottom of the wall. This is where you will hang your first length. 

Paste

Step 4: Empty some paste into your tray. Evenly roll the paste where you are going to hang your first length, ensuring you paste slightly wider than the width of the roll. This will ensure that your seams will be securely stuck to the wall. Use a paint brush to apply paste along the top and bottom of the wall, and around any sockets. 

Hang

Step 5: Hang your first length by carefully and slowly pulling the wallpaper up from the roll and position it so you have roughly 10cm of a overhang to allow for trimming. Hang it making sure the edge of the paper aligns with your vertical line. Gently flatten out the paper using your hands. Continue to do so until you have attached all of the first length to the wall. It is important that you take your time to get the first length of wallpaper correctly hung as otherwise it can end up looking a little wonky! 

Smooth

Step 6: Using your tool, gently smooth out all air bubbles, working from the centre outwards.

Finish

Step 7: Cut the excess paper at the top and bottom with a craft knife or a pair of scissors. 

Step 8: Push the trimming tool firmly into the top of the skirting board so it is sitting nice and snug and use a craft knife to cut along. Do the same for the top of the paper.
