Lining paper is a cheap method of covering an uneven wall prior to hanging heavy textured
or expensive papers. It is also a useful method of providing an even surface to emulsion
over.
Hang the lining paper horizontally or vertically, taking care to match the seams
edge to edge, not overlapping. Paper can be pasted over damaged and uneven surfaces over,
but avoid hard edges as they may show through the wallpaper. It may not be necessary to
cover all the surface, if some large areas are smooth.
Paste the lining paper over affected areas, allowing a small amount to be loose all
around. Once the paste has dried, tear the surplus away leaving a tapered, ragged edge.
If any hardness results, sand lightly to blend into the wall.
