Wallpapering: Cutting Wallpaper to Size
Cutting a plain, striped or textured paper presents no problems of pattern matching. Cut sufficient lengths to paper at least half the room. (Some people advocate cutting all the lengths, including shorter lengths to go over doors, fireplaces and over and under windows.) When cutting each length, allow between 50mm and 75mm at each end for trimming.
A paper with a definite pattern needs cutting carefully. Place a length of paper, design upright, on the paste table and find the main motif or pattern. Cut the paper 75mm above this pattern, measure the length required and then add on an extra 75mm at the bottom. This gives the standard pattern drop.
Move this paper across the table, unroll the paper again and match up the next length to be cut. If the pattern has a big ‘drop’ there will be some wastage. It may be more economical to take another roll and match the next length from that, taking alternate lengths from two rolls. Manufacturers normally give guidance on the particular pattern drop for each design.
It is important to use thespecified by the manufacturer, for the type of wall covering to be used. Paste should be mixed exactly as specified and used while it is still fresh. Generally, the thicker the paper the thicker the paste.
There are two main types of paste: starch flour paste, which is mixed with hot or cold water; or water-soluble cellulose paste. Tub paste, sold in containers, comes into the latter category and is thinned with cold water. Cellulose pastes are easier to use and if accidentally spilt on the paper surface, will dry out without marking.
Unless you are using a vinyl paper or special wall-covering material, the paste should be allowed to soak in. The time allowed for this, as a general guide line, is the time taken to repeat the pasting sequence with the next length of paper.
While starch flour or cellulose pastes are suitable for most normal papers, these should not be used in kitchens or bathrooms.
In kitchens and bathrooms, where there may be high condensation, vinyls and washable papers, which have an impervious or nearly impervious finish, should be hung with a fungicidal paste. There are various heavy-duty fungicidal pastes available.
