Types of Wallpaper
This is the most common type of wallpaper. The cheaper papers, known as ‘pulps’, have the design printed directly on to the paper, while the more expensive are coated with a ‘ground’ of colour before the design is printed.
Papers vary in weight, and the cheaper, thinner papers may stretch and distort if over-soaked with paste before you hang them Thick papers can be useful to help conceal minor defects on a wall.
This is produced by block, screen or stencil printing, and because of the amount of time taken in production it is expensive.
This has the design pressed into it with a metal roller so that it stands out in relief. Imitation leather, textile and wood grain effects are produced by this process. Duplex embossed papers are produced by bonding two layers of paper, before the design is pressed out, to make the paper more stretch-resistant. Flock paper. This has the appearance of velvet. It is made bysilk, nylon or wool cuttings to the surface of the paper so that the design stands out in relief and has a noticeable pile.
An ‘oatmeal’ texture is given by the addition of small wood chips and sawdust to the pulp during manufacture. The paper is usually emulsion painted after it has been hung.
A glossy or matt transparent coating protects this paper against penetration by water, making it suitable for use in bathrooms and kitchens. It can be washed with warm soapy water, but should not be scrubbed.
These papers have an attractive sheen which has been achieved by adding mica to the grounding to give a satin-like surface or to the inks to heighten the effect of the pattern.
A watered silk effect, similar to moire material and achieved by means of a fine emboss. This effect may also be reproduced on cheaper papers by printing. Ready-pasted paper. This has anin `dry’ form applied to the reverse side during manufacture. To ‘activate’ the , the cut lengths are immersed in water in a trough for about one minute immediately before hanging.
This is essential on some surfaces, such as painted walls, but it is also advisable to use it before hanging Anaglypta or heavy-weight papers.
Lining papers are available in several weights. Use lighter papers on normal wall surfaces, heavier papers to help conceal an uneven surface.
Surfaces that are subject to movement, such as tongued and grooved woodwork and battened wallboards, can be lined with a cotton-backed lining paper.
