Unrestricted access is a must for paperhanging. When working on just the walls, move all the furniture to the centre of the room and cover it with dust sheets (drop cloths). When tackling the ceiling too, it is best to remove all the furniture completely if there is space to store it elsewhere in the house; otherwise group it at one end of the room so that most of the ceiling can be done, and then move it to the other end to complete the job.
Next, take down curtains and Hinds (drapes and shades) and remove wall-or ceiling-mounted tracks. Turn off the electricity supply at the mains, then disconnect and remove wall or ceiling light fittings as necessary, covering the bare wire ends thoroughly with insulating tape before restoring the power supply to the rest of the house. In the USA, ceiling roses, wall switch plates and socket outlets can be unscrewed and removed without disconnecting the wall receptacles or switches. Isolate, drain, disconnect and remove radiators, and unscrew their wall brackets. Call in a professional electrician or plumber for these jobs if you are unsure of how to do them safely.
Take down pictures, and remove other wall-mounted fittings such as shelves and display units. To make it easy to locate the screw holes afterwards, push a matchstick (wooden match) into each one.
Start paper hanging at the centre of a chimney beam (fireplace projection) if the wall covering has a large, dominant pattern. Otherwise start next to the door so the inevitable pattern break can be disguised above it.
Work outwards from the centre of a dormer window so the design is centred on the window recess.
If the walls and ceiling are at present painted, they need washing down to remove dirt, grease, smoke stains and the like. If they are decorated with another wall covering, this will have robe removed and any defects in the surface put right. Finally, they need sizing — treating with a diluted coat of wallpaper adhesive to even out the porosity of the surface and to help to improve the ‘slip’ of the pasted wall covering during hanging.
The next job is to estimate how many rolls of wall covering will be needed to decorate the room. If using a material that comes in standard-sized rolls, simply measure the room dimensions and refer to the charts given here for the number of rolls needed to cover the walls and ceiling. They allow for atypical door and window area; fewer rolls are needed for a room with large picture windows or wide door openings. If using a paper-backed cloth covering which comes in a non-standard width, measure up each wall, and ask the supplier to estimate what length of material you will need; such materials are too expensive to waste. Walls are sufficient roils with the same hatch coverings in the USA vary in width number; colours may not match exactly and length but arc usually available in-between hatches.
