The problem with metallic wallpapers is that the backing expands at a different rate than the front when pasted, due to the print being so heavy. Lining paper is an absolute must to hold down the seams whilst the paper is drying. The seams will want to pucker up and the liner helps hold these down as it will have a much stronger grip on the finish paper than if it was hung directly on plaster.
We finished the installation just in time for the opening of the show home and we received this email just a few hours after we left, which is always nice.
“Thanks for attending today, we had rave reviews from directors of Taylor Wimpey!”
