Splitting seams

Splitting seams (paper)

One possible cause for splitting seams following wallpapering could be a sealed surface, draughts or individual strips may have dried too quickly. If you use a dispersion adhesive (e.g. Metylan Ovalit T), you need to be aware that you must soak the wallpaper for a longer period.

A good quality brand all-purpose adhesive is usually suitable for well-prepared surfaces. We recommend using speciality wallpaper paste for critical or heavy paper products. Remember that the soaking time needs to be adjusted accordingly.

We would advise using the “folding rule method” in order to find out if the wallpaper has to soak for a longer period.
You need a folding rule and a stopwatch.
Measure the width of the strip when it is dry (53 cm, 70 cm or 1.06 m wide).
Paste the strip as instructed in the package insert, fold it and then roll it up.
Next measure the width of the pasted and rolled up strip. It will probably be around 53.4 or 53.5 cm. Keep measuring the rolled up wallpaper and check the time until the width has reached 54 cm. This is the perfect timing to put the strip on the wall. 
The folding rule method tells you how long you need to soak each subsequent wallpaper strip.

Splitting seams (non-woven)

This could be caused by an incorrect amount of paste, draughts or a surface that is unsuitable for wallpapering.
