  2. 2. Wall covering is the exterior wall skin consisting of panels or sheet. A covering on a wall could be vinyl or paper wallpaper, melamine laminate and stretched coverings etc. Wall covering may be a flexible sheet of sized paper, fabric, plastic etc. usually laminated and printed with a repeat pattern for pasting on the wall as a decoration and presentation. The texture of wall coverings vary from cold, shinny, smooth surface of glass.
  3. 3. Types of walls The selection of wall covering has a great deal to do with the type of wall being covered: Brick Make sure that there is no dampness on the wall. If brick walls have been left unpainted, they can be covered with a clear sealant to prevent them from crumbling or becoming dust traps. Old plaster Plaster is suitable for most wall coverings and paints. If the plaster is uneven or cracked, use wallpaper or other covering materials or line the wall with lining or ingrain paper before painting or finishing. New plaster It must be absolutely dry before decorating can begin. If it is to be painted before it is absolutely dry emulsion paint is better as it is least likely to blister and allows the wall to breathe.

  7. 7. Wallpapers This type of wall covering evolved as an inexpensive substitute for the tapestries of the wealthy. The choice of wallpaper depends upon the dimensions and uses of the room. Wallpapers have a warmer look than paint. Lining paper A preliminary covering of plain paper gives the wall an even porosity, which helps when painting or hinging the final wall covering. Surface printed papers The cheaper papers are called pulp. Higher quality papers, known as grounded papers are given a coating of color before the design is printed on these. Washable paper A transparent waterproof film stops moisture, including steam, from damaging the design. These papers are especially suitable for bathrooms and kitchens. Embossed papers The design is pressed into the paper to make it stand out in relief. This process produces wood-like grain, imitation leather, and textile effects. Anaglypta Two layers of paper and cotton fiber are bonded together and embossed to produce anaglypta. These are available typically in white, but can be decorated with matt or silk- finish emulsion paint.
  8. 8. Fabric Coverings Fabrics fall into two main categories: fabrics that actually surface a wall in the manner of wallpaper and those that are draped loosely across a wall. The fabric is stretched on a wooden frame, which can then be attached to the wall at just a few points Fabric can also be hung in soft folds, as a continuation of window drapery or for its own sake as a supple alternative to patterned wallpaper Grass cloth, made of loosely woven grasses and reeds affixed to a paper backing, can be handled like wallpaper as well.
  9. 9. Wood The rough texture of wood on walls generates warmth. The woods used for wall paneling are usually hard, well seasoned, and of a decorative appearance Wood paneling comes in many variations of color, tone, and texture and may be either solid or wood- veneered Wood veneers may be stuck to paper too, giving an effect similar to solid wood at a much lower cost. Veneered plywood paneling is also popular. Wood paneling may be found in such places as entrance halls and staircases, convention rooms, and restaurants.

  12. 12. Maintenance Periodic cleaning should be scheduled so that obstinate dust and grime do not settle in. Before cleaning the walls, remove any pictures, mirrors, or accessories hung up on them.
