Wallpaper pastes have a typical shear thinning viscosity and a high wet adhesive tack. [citation needed] These properties are needed to slow down the penetration of the adhesive into the paper and wall, and give slow bonding speed which gives the wallpaper hanger time to line up the wallpaper correctly on the wall.

Modern wallpaper is made in long rolls which are hung vertically on a wall. Patterned wallpapers are designed so that the pattern "repeats", and thus pieces cut from the same roll can be hung next to each other so as to continue the pattern without it being easy to see where the join between two pieces occurs.

Lincrusta is made from a paste of gelled linseed oil and wood flour spread onto a paper base. [2] It is then rolled between steel rollers, one of which has a pattern embossed upon it. [ 5 ] The linseed gel continues to dry for many years, so the surface gets harder over time.
Apart from heat and humidity, bleach, salt, and chlorine can also shorten coating life. [3] If PUL is kept wet for a long time, it disintegrates into the water and sticks to itself, though it will probably go mouldy first. [7] If the polyurethane starts delaminating from the fabric, it may be possible to relaminate it with care and a hot iron.
