How to Hang Paste the Wall Wallpaper
Paste the wall is exactly that! Paste the wall and hang, then paste and hang as you go. You are working with a dry product and the newest style of wallpaper we call non wovens.
Paste the wall wallcoverings are the easiest of all wallcoverings to hang. This is because of the structure of the backing, which is known as non-woven or fleece.
Because the non-woven backing is very strong, it does not expand or contract when wet, which means that when the sheets are aligned correctly, there is no shrinking or expansion at the joins.
Preparation of the wall remains exactly the same as when hanging any wallpaper the traditional way. Preparation is the most important part that can make or break the finished job.
1. remove old wallpaper
2. walls must be clean and dry, sealed and cured
3. if necessary, prime with a pigmented sealer (Zinsser Shieldz) on very porous unpainted surfaces such as gyprock, or over old firm wallpaper that is impossible to remove.
4. cement render surfaces will require a lining paper as a base to overcome the rough texture and ensure good adhesion.
5. sandpaper, dust and apply glue size before hanging wallcoverings allowing to dry thoroughly
6. painted surfaces, in particular gloss enamel, should be washed with sugar soap and rinsed then sanded with an 80 grit sandpaper. Dust and size*
*Size can be made up by making up a weaker solution of glue (Metylan or Bartoline Powder) or it can be provided as a latex size (Superbond Latex). It is an important step in wall prep to enable adequate adhesion, ease of application and then later removal of wallpapers.
PREPARING METYLAN PASTE
1. use only Metylan Paste when applying non woven backed wallcoverings. Crockers also have another suitable glue: Bartoline Powder for smaller jobs.
2. sprinkle the contents of one packet of Metylan (200gms) gradually into 4 litres of cold water whilst stirring firmly (use an old egg whisk!). Repeat after approx 3 mins and beat well after about 25-30 minutes. The paste is now ready for use.
3. one packet of Metylan is sufficient for approx 4-5 rolls of wallpaper pending how much moisture the wall will absorb.
HANGING “PASTE THE WALL” WALLPAPER
1. apply paste directly to the wall with a medium nap roller or wide brush. Using a roller will be faster, however ensure you brush well glue into corners and along edges.
2. paste the wall for the first drop, allowing slightly wider than the roll width. Ensure that sufficient glue is used to wet the wallcovering well when it gets applied.
3. apply the wallcovering from the roll onto the wall leaving approx 5cm extra on top and bottom for trimming. When positioned correctly, smooth out from the centre to the edges using a wallpaper laybrush or smoother, removing any air bubbles. Ensure edges/seams are stuck firmly to the wall. Run a pasted brush down the seam if needed. Do not use a seam roller. This can damage and flatten the pattern making seams more prominent.
4. trim off excess wallpaper and rinse away any excess glue left on skirting boards and ceiling cornices.
5. before cutting your next drop, check the pattern repeat by aligning against the drop already hung and then cutting accordingly. Some wallpapers will have no repeat, so check the label concerning the design.
6. if any areas need to be overlapped e.g in corners then a ready mixed border adhesive will be required to adequately secure these edges. Overlapping however is not always required and not recommended unless in an inconspicuous area e.g behind doors or in a dark corner.
NB: PLEASE NOTE IF PROBLEMS OCCUR OR THERE IS A FAULT WITH THE WALLPAPER DESIGN, THEN DO NOT PROCEED WITH THE JOB. CONTACT YOUR RETAILER FOR FURTHER ADVICE AND INSTRUCTIONS.
