How to Paste and Fold Wallpaper for Hanging
The paste should be mixed according to container instructions and it may be applied with a brush or roller to the back of the paper. It will be found best to work with one end of the papering table near a light so that any missed patches of paper may be seen when pasting. The amount of paste to apply to the back of the paper will vary according to the thickness of the paper and the correct application is largely a matter of experience. As a general guide it may be taken that thin papers require less paste than thick papers. If thin papers are over-pasted they may tear or drape when being hung. Cellulose-based paste can be applied to medium-weight papers quite liberally. The paste should be brushed or rolled on the centre of the paper first, working methodically from the end of the table to the unsupported ends of the paper. After pasting the middle of the strip, work the brush or roller outwards towards the edges.
It is bad practice to use brush or roller from the edge to the middle of the paper. If this is done a certain amount of paste is bound to be scraped off on the edges and will creep under the sides of the strip. Every care should be taken when pasting and handling paper not to coat the paste on the face side. In the case of cellulose-based pastes, these will not mark the face of the paper, but it is a good habit right from the start to avoid marking the front of the paper if possible.
With one end of the strip pasted, the paper should be folded and moved along the table so that the remaining part of the strip can be coated with paste. There is a definite sequence of movements for doing this simple job. Move all the strips back together for 2 in. or 3 in. away from the edge of the table, still keeping the back edges of the strips under-lapping.
With this done, wipe the edge of the table with a decorator’s sponge to remove any traces of paste that have been brushed on the edge of the table. With the front edge cleaned draw the top strip back to the edge of the table. Take the pasted end and fold it so that the pasted sides of the paper are together. The beginner may find it necessary to make several attempts before doing this part of the job properly. Make sure that the edges of the folded end of the strip coincide and lightly smooth the folded paper with the hand. The top strip should then be moved along the table and the unpasted end coated with paste. This end of the paper should also be folded over after wiping the edge of the table as was the first end. This is done to ensure that the thickness of paste is spread evenly over the surface of the paper and to make the pasted strip easy to handle.
If the piece is extra long and it cannot be pasted in two movements of the paper, the paper should be folded in a concertina fashion. Thin papers should be hung immediately they are pasted. Papers of medium thickness may be left for a few minutes before hanging them to allow the paste to soak into the paper. Thick papers should be left to soak for several minutes and soaking and pasting instructions are usually given with these extra thick papers when they are purchased. The sequence of pasting and folding the paper is the same for all pieces throughout the job, always remembering to wipe the front edges of the table and keeping the back edges overlapping.
