However, in a pinch, putting box fans on the area will generally expedite drying time (3+ hours)and still allow the sealer do what it does so well **Q: Will this work for 60 grit sanded down old formica dinner table that will be top coated with Behr paint and primer and then stonecoat epoxied?** A: Hi Jim, PRO-999 Rx-35 is formulated to seal porous surfaces like drywall and joint compound. As Formica is a non-porous, sealed surface, PRO-999 may not be the best primer option for this project. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***E on 31 December 2024* 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. ### ⭐⭐⭐⭐⭐ Review *by R***E on 22 September 2022* 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. ### ⭐⭐⭐⭐⭐ Review *by A***. on 11 November 2025* 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. ## Frequently Bought Together - Roman PRO-999 Rx-35 Wallpaper Primer and Sealer - Bonding Primer for Wallcoverings and Home Improvement, Clear, Water-based - 1 Gallon (400 Sq.
