First got this product 3months ago,and for the first month it's been great, and looked beautiful! Then one day we came home and one of the corners had started peeling off, no big deal we just smoothed it back on the wall. Then about a week after that we came home to find half the wall had peeled down and was sticking very well to itself and not the wall. Not as easy this time to tack back up and had to pull the wallpaper off of itself before reapplying to the wall, but got it back up. Not wanting it to happen again we applied a good amount of clear packing tape to hold it up hoping this would work and it did, until we left for a week and came back to find the entire walls in our two different rooms had completely detached, and was now stuck to our furniture as well. We live in Austin, TX, humidity has averaged 74%, temp inside 68-72 F, new flat white paint on walls month prior to install, lite orange peel standard texturing, forced air, and ceiling fan also installed. We only purchased the wallpaper a month prior to install and the packaging is from 2016 and the addhessive should still hold strong?! Very disappointed with the non sticking self stick wallpaper for what otherwise would be a very beautiful product.
