How to Install


Preparation is most important. Good preparation will ensure a great result. The walls must be clean, dry, smooth, grease-free and structurally sound. For best results, remove all old wallpaper first. Any dampness must be investigated and repaired before you proceed. Previously painted surfaces should to be sanded to a matt surface.

Raw surfaces, including old plasterboard linings and surfaces painted with latex paint (PVC), should be sealed with oil based pigmented sealer prior to sanding. Gloss enamel paint surfaces should be sanded after washing down with a sugar soap mixture. Whatever the surface, dust thoroughly before applying size.

Where To Start?

Choose the most well lit corner of the room, measure the width of one roll in from the corner. Subtract 15mm and mark that point (high on the wall close to the ceiling away from the corner) and hang the first drop, followed by the second (back into the corner). This will allow for an (approx.) 15mm return to cover inside the corner.

Now measure all walls in the room (height). Then allow at least 50mm for trimming top and bottom (total 100mm or more per drop) over and above the longest wall measurements. Cut your first drop to this size; then use as a template for all others.

Make A Plumb Line

Identify your mark and place a small nail on it. Attach your plumb line then draw a line (in pencil) down the line to the floor.

Proceed With Caution On Corners

Inside corners should be hung with two drops. Whenever vinyl overlaps vinyl, you will need to use PVA glue for a good join.

Outside corners should be handled in the same manner, however allow for double the wrap around onto the adjacent wall (30mm).

Beware Of Obstacles

Rooms of course have features other than walls. Like doors, windows, power points and light switches. Don’t be daunted, the solutions are simple.

For a simple rectangular switch, lay your drop of wallpaper over the switch (in its final position). With your pencil, mark off the four corners of the switch, then join them with a pencil line to mirror the switch dimensions. Lift the paper off and, using your scissors, cut from the middle of the switch area to the four corner points (to create four triangles). Now push this over the switch and trim off the excess. (If you don’t feel confident at first a good idea is to take a piece of newspaper and practise the procedures before doing the real thing.)

Doors and windows are handled in much the same way. Hang a full drop of wallpaper so it overlaps the frame. Smooth the paper up to the frame as close as possible, then cut on the diagonal to the corner point of the frame. Lift the flaps and carefully smooth the edges in, crease and finally trim off the excess.
