Wallpaper failure at the biggest level
Printer used – Mutoh eco solvent
Materail- WW300 Canvas unlaminated
So, let me take you back to april, spring. I had a rare slow day and come late morning i decided to wallpaper my man cave, a job i had been waiting to do for almost a year so i print it all and fit it in the same day.
Over the next 4 to 6 weeks i notice the outside edges starting to curl. I squeegee them down and hope for the best. This continues for a few months to the point now i have left it and as you can see its just got worse. Now having spent the last few months self harming i have now come to terms with having to sort this out but im really undecided on the cause of the problem.
Initially i thought that having trimmed the drops out within 30 mins or so and fitted them straight away that this was the problem. ( I have done half a dozen jobs for customers and always leave 12hrs)
but there are other things going on here that confuse me. The wallpaper was fitted flush to the wall edge and now you can see a 5mm gap. Its not just the edges which have problems, there are creases lumps and bubbles all over, even the overlap edges have come away.
So now i have two other options which i am looking at –
The paint and substrate of the wall – 5mm chipboard that was painted a few years ago with paint that has a high VOC of 30.
And humidity- Being chipboard it does expand and shrink with the seasons. Our house goes from 10% in winter to 60% in summer.
Also being chipboard from the 50s apparently there is some sort of smell/toxings that these older materials let off, could this be the problem.
So there we have, i want to make sure if i redo this it never happens again. Really my next step is to do some testers.
I find it hard to believe that trimming too soon off the printer has caused this.
As a note, in the other end of the house we run a BnB, on one of the walls i fitted our logo as a sticker to the wall (chipboard) and it fell off the wall within days. I then made a foamex sign a taped it to the wall which also kept coming down so the only thing was fixings which did it. This is why im leaning towards paint/substrate issue.
