International Wallpaper Symbols
Wallcovering manufacturers are now using these international symbols on their product labels and in pattern books to indicate the type of wallpaper and how it should be used.
A wallcovering from which the adhesive may be wiped off the face of the paper with a damp soft cloth or sponge at the time of hanging without causing visible damage, providing it is done whilst the adhesive is still damp. No subsequent washability is claimed or implied.
Washable wallcoverings are finished products from which dirt and some domestic water based stains may be cleaned carefully from the front face with a damp cloth and soapy water. Oils, fats and solvents based stains are not expected to be removable.
A finshed wallcovering of superior cleanability from which dirt and most domestic water-based stains may be cleaned from the front face with a sponge or soft brush and a mild detergent or a mild abrasive. Oils, fats and certain solvent-based stains may also be removed if tackled immediately after contamination.
Good Light Fastness
This means that the wallpaper should retain its original colour for a considerable amount of time, but can't be guaranteed on any permanent basis. Has a minimum rating of 5 when tested in accordance with the EN233 lightfast testing procedure.
Moderate Light Fastness
This product may well fade or discolour in areas of direct sunlight and has a minimum rating of 3 when tested in accordance with the EN233 lightfast testing procedure.
Adhesive to wallcovering
Means that the adhesive should be applied to the reverse of the wall covering before application to the wall.
Wall covering already has a thin, dry layer of adhesive on the reverse of the paper. The paper would require submerging into a water trough, at the point of hanging, to activate the adhesive.
Paste the Wall
Adhesive should be applied to the surface that the wall covering is being hung onto. E.g. the wall and the paper applied dry direct from the roll. Note: The paper can still be pasted and hung in the conventional way if desired.
A wall covering whereby large strips may be manually removed, by pulling, whilst the paper is dry, completely removing it from the substrate (wall) it was attached to.
A wall covering that would require wetting or steaming, or the use of a proprietary stripping agent, to reactivate the adhesive behind the paper before scraping off from the wall.
A wall covering from which the printed decorative face can be manually removed, either as whole or in at least large pieces, whilst still dry. This would then leave a backing layer that could be easily soaked off. A PVC vinyl wall covering is a good example of this.
This is sometimes called a Half Drop - the match is obtained by halving the repeat.
The pattern matches straight across the width.
No matching required; lengths can be cut straight from the roll without wastage.
Mostly applicable to plain effects and necessary to minimise the risk of side to side shading.
