Roman PRO-999 Rx-35 Wallpaper Primer and Sealer - Bonding Primer for Wallcoverings and Home Improvement, Water-based - 1 Gallon, Clear

Roman PRO-999 is for non-porous wall or other surfaces. It dries fairly quickly and dries clear and leaves a tacky finish on the wall or surface. The tackiness increases the adhesion of wallpaper or other surface material.

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.

Professional paper hanger

Applies easily, great coverage, dries fast with little smell and best of all,the wallpaper sticks!

Great product my bathroom ceiling use to peel paint really bad put this on. It haven’t had any pilling since.

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.

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.

Used on wall after decals tore the Sheetrock. Had to add more paint to that area after it dried because this stuff leaves a shiny film

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.
