Review: So easy for a first-time user - 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.
Review: Works - Great product my bathroom ceiling use to peel paint really bad put this on. It haven’t had any pilling since.

## Questions & Answers

**Q: How long to set before I can wallpaper over it?**
A: 30-45 minutes until it dries and becomes tacky.

**Q: Can I use acrylic paint on top of Roman 999?**
A: yes

**Q: What is the dry time?**
A: To get the desired result ie. protect the surface and get increased slip and slide, let it dry overnight.  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.

### ⭐⭐⭐⭐⭐ THE first step when installing wallpaper
*by R***N on August 30, 2025*

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.
