I'm a professional installer and have installed dozens of Chesapeake prepasted products. Over the years we've gone from adding extra paste to simply dipping the product per the manufacturer's instructions because it gave a better result. That is, until I installed this product. We hung it in a small bathroom and within 30 minutes of hanging every seam in the room had dried, shrunk, and lifted. We had to go back and repaste every seam in the bathroom due to weak adhesion and shrinking. Fortunately, we were able to ensure a good finished result but it was in spite of the quality of the product. I would not recommend this Wallcovering for novice installers or DIY as extra adhesive is required for it to remain on the wall.
