Decorating 101: Wallpapering Adhesives – Where to begin
Where to begin…Adhesives
PASTE: Cellulose-based adhesive is used for all standard wallpapers, including heavy-duty which relates to the weight of the wallpaper being hung. These are presented in a flake form which is dispersed into water, the volume of water dictates the concentration of the solids that form the adhesion, this is commonly known as wallpaper paste.
FUNGICIDAL PASTE: As vinyl and washable wallcoverings are impervious, mould could attack the paste unless it contains fungicide, check pack for details. Fungicidal paste is also needed if the wall you are decorating has been previously been treated against mould or if any sign of damp can be seen.
READY MIXED ADHESIVE: Heavy duty adhesives (ready mixed paste) are for heavy weighted wallpapers and for temperature / humidity variable spaces such as kitchens or bathrooms. These are presented in ready made form, increased concentrations and solids allow better adhesion and more grab.
Some super-heavyweight wallpapers and wallcoverings such as polystyrene veneers, hessians and grasscloths require an especially concentrated adhesive which may be applied to the product itself or directly on to the wall (always follow manufacturers instructions). At present we are unable to supply ready mixed adhesives in large enough quanitites online due to risk of spillage during shipping.
Our brands of wallpaper paste are suitable for all types of wallcoverings, see reverse of packaging indicating the ratio of paste to water.
OVERLAP ADHESIVE: When finishing off wallpapering around corners, overlapping vinyl’s and washable wallcoverings or sticking down stubborn joints, a vinyl-to-vinyl adhesive is ideal (sometimes referred to as border and overlap adhesive), it is also available in tubes for ease of application
SIZE: Wall Size is used to prepare plaster and porous surfaces, it prevent the paste soaking into the walls and helps the wallpaper to slide into place easier. When buying a size, ensure it contains a fungicide if you also require a paste with fungicide. Apply with an brush and use a damp cloth to remove any runs onto paintwork as this can be difficult once the size has dried. Sizing can be done several days in advance or up to an hour before.
DAMP: Damp proof foil could be of used if their is a minor damp issue, the appropriate adhesive must be used to ensure adhesion to the damp surface.

Where to begin…Wallpapering
wallpapering, traditionally it is recommended to start next to a window and work away from it, however this method was really used when wallpaper was overlapped so shadows were minimised. Now wallpapers are butt joined the light isn’t generally an issue, but as the pattern may be lost around corners you can make this as inconspicuous as possible.
In the average room, the corner closest to the door is the best place to start work, any loss of pattern will then end up behind you as you enter the room, nicely hidden.
With a feature wall, if there is a chimney breast, hang the first strip down the centre of the chimney and work out from both sides towards the corners of the room.
