Once the previous wall and ceiling decorations have been removed the next task is to restore any defects in the surfaces to be covered, and then to prepare them so that they present the perfect substrate for successful paperhanging.
The first step is to put down some heavy-dory plastic sheeting on the floor to catch splashes, and then to wash down the hare wall and ceiling surfaces thoroughly with strong household detergent or sugar soap (all-purpose cleaner), working from the bottom upon walls, and then to rinse them off with clean water, working this time from top to bottom on walls. Turn off the electricity supply first in case water gets into light switches and socket outlets (receptacles). Leave the surfaces to dry out thoroughly.
Next, repair defects such as cracks, holes and other surface damage which may have been concealed by the previous decorations, or even caused by their removal.
Finally, treat the wall and ceiling surfaces with a coat of size or diluted wallpaper paste, and leave this to dry before starting paperhanging. Size seals porous plaster, providing a surface with absorption, and also makes it easier to slide the pasted lengths of wall covering into position on the wall.
Wash wall surfaces with sugar soap (all-purpose cleaner) or detergent, working from the bottom up , then rinse them with clean water, working from the top down
Wash ceilings with a floor mop or squeegee, after disconnecting and removing light fitting.. Again, rinse off with clean water.
Fill cracks, holes other detects in the wall and ceiling surfaces as appropriate, leave the filler to harden and then sand the repair down flush.
Apply a coat of size or diluted wallpaper paste to wall and ceiling surfaces that are to be papered, and leave them to dry before starting paperhanging.
If the wall surface is in poor condition, has been previously decorated with gloss paint or is being decorated with a thin fabric wall covering, it is best to hang lining(liner) paper first. This is usually hung horizontally rather than vertically, with butt joints between lengths and with ends and edges trimmed just shun of adjacent ceiling and wall surfaces. Use the same type of paste for the lining paper as for the subsequent wall covering.
MEASURING AND CUTTING TO LENGTH
1. For quick and easy calculations, mark the length of the pasting table at 30 cm/12 in intervals using a pencil and metal straight edge.
2. Measure the length of wall covering needed for the drop, including trim allowances., and mark this on the paper. Cur the first piece to length.
PASTING WALL COVERINGS
1. Face the light to make it easy to spot any unpasted areas – they look dull, nor shiny. Apply a generous hand of pastedown the centre of the length.
2. Align one edge of the wall covering with the edge of the pasting table, then brush the paste out towards that edge from the centre band.
3. Draw the length across to the other edge of the table, and apply paste out to that edge Rio. Check that there are no dry or thinly pasted areas.
4. Continue pasting until the end of the table is reached. Then lift the pasted end of the wall covering and fold it over on itself, pasted side to pasted side.
5. Slide the paper along the table so the folded section hangs down. Paste the rest of the length and fold the opposite end over on itself.
