Easy to apply sizing and wallpaper adheres to product and stays once dried. After applying the sizing to the wall, let dry about 1-2 hours. It will be tacky after drying, then apply the wallpaper. Easy soap and water cleanup. No smell and covers a lot. I still have 3/4 gallon after papering my bathroom.

I carefully removed tiles from the bathroom walls in order to not damage the drywall too much. This product worked to lay down torn drywall, and bound, and strengthen. I then followed with drywall compound on top. A little goes a long way.

I’ve always been intimidated to hang real wallpaper and have stuck to “peel and stick”, but using this was about a thousand times easier than peel and stick. It was forgiving to move the paper around, held well once dried and we are a few months in with no bubbles and no issues.

A must-have prior to installing wallpaper. Water-based so clean-up is easy and RX-35 ensures great adhesion and protects the surface years later when it's time for a change and you need to remove the existing wallpaper.
