Decorating 101: Wallpaper Preparation...

Author: Home Flair Decor
Wallpaper Preparation is vital to give you the absolute best results in your environment, please use the below information as a guide to give you excellent results.

Previously Papered Surfaces,

Strip the wall completely before repapering. There is no way to guarantee that any previous paper/linings will stay adhered tote wall once the new wallpaper is overhung.

Peel away any top layers of paper/vinyl where possible so you can get moisture into the lining. Wet the paper several times with warm soapy water or wallpaper stripper, apply liberally with an old brush or cloth until the paper becomes soft. Scrape the paper off with a broad stripping knife, being careful not to dig into the wall.

Score any wallpaper that you cannot remove the top layer (painted, varnished or cushion vinyl), this will allow the moisture to get through to the lining.

New Plaster,

If you have moved into a new house or have undecorated plaster walls, check how long you have to wait before you can over decorate, some plasters require up to six months before decorating vinyl wallpapers

New Plasterboard,

Seal with a primer to prevent the moisture from softening the plaster and making it porous. Hang lining paper as a backing for the final paper for bet results. Use a low-moisture adhesive and our paste the wall lining as an alternative to priming the plasterboard.

Emulsion Painted Surfaces,

If the surface is sound and has a matt finish, lightly sand the walls and size (What is size? See below). Add a small amount of fine plaster to the size to give a great key. Apply lining paper first if using a heavyweight wallpaper, such as our Belgravia Italian vinyls. Flaking emulsion must be stripped.

Oil Painted Surfaces,

Rub down thoroughly with a sanding block and rinse off with clean water, fill any cracks and hang lining paper. Gloss paint must be stripped.

Sizing,

Glue size prevents a wall from absorbing the moisture from the paste too quickly giving you time to reposition the paper you are hanging. Size is a powdered product and is mixed with water (follow the instructions on the packet). If the size is too strong it could make the wall to slippery, making it very difficult to hang any paper over it. After sealing, allow the wall to fully dry and sand lightly prior to hanging any wallpaper.

Lining Paper,

This can be overprinted to help disguise badly cracked/uneven walls or used as a backing for a final layer of wallpaper. If overhanging, hang lining paper horizontally and butt-join each sheet. Cut strips of paper to cover the length of the wall, paste them and fold in a concertina, start hanging at the top of the wall and work downward with each strip. Do not hang a continuous strip around any corners, take each strip around about 2.5cm (1 inch) and then butt-join the next strip.

Do not line the whole wall if you are just wanting to cover a small damaged area, such as damage from a removed dado/chair rail, hang lining across the damaged area and leave the edges hanging loose. Once the paste has dried, tear the edges off and sand them down to remove any "step up".
