1.1 This British Standard specifies the requirements for adhesives suitable for hanging flexible wallcoverings and ceiling coverings supplied in roll form, having a total grammage (see BS 3432) below 500 g/m2. Five types of adhesive are specified to enable the wallcovering manufacturer or other user to recommend the preferred type or types for a given wallcovering.
Type 1. For use as a low solids adhesive with easy slip showing very low marking and very low tarnishing; especially suitable for light grammage wallcoverings.
Type 2. Normally used as a medium solids adhesive, showing low marking and low tarnishing; suitable for wallcoverings of all grammages and also for previous, washable wallcoverings.
Type 3. Adhesive with good wet adhesion, particularly suitable for wallcoverings of heavy grammages and also for previous, washable wallcoverings.
Type 4. Adhesive containing fungicide to inhibit mould growth (mould resistant), suitable for impervious wallcoverings of all grammages.
Type 5. High wet adhesion, high dry strength adhesive, containing fungicide to inhibit mould growth (mould resistant), suitable for most impervious wallcoverings or special applications, often ready-mixed.
1.2 This standard is applicable to adhesives supplied either in powder form or ready-mixed. The prepared adhesive (see clause 7) may be applied by the decorator either to the wallcovering or to the wall or ceiling surface, according to instructions supplied by the manufacturer of the wallcovering.
NOTE 1 Certain requirements of this standard may also be applicable to ready-pasted wallcoverings.
NOTE 2 Although the inclusion of a fungicide in types 4 and 5 adhesives is mandatory, it may also be included in adhesives of types 1, 2 and 3.
