Great product! **Q: Can I use what’s left over as a regular primer for paint?** A: I’m not a professional, but, I’d think it would make a good primer as well! It dries as a “satin ” finish and I would think any cover paint would adhere to it well. **Q: Can this be used over existing wallpaper in order to paste new wallpaper on top?** A: Yes, but you should not hang new wallpaper over existing wallpaper for a variety of reasons. See my book, Interior Architectural Painting: a tradesman’s guide, for more information. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked out GREAT . Pre treatment ! *by J***S on May 9, 2025* So easy a kid can do it! First picture shows my son who wanted to help update his room apply the paint . This was simple and the before part of applying his peel and stick wall paper shown in second photo . Good quality dries quickly and worth it! ### ⭐⭐⭐⭐⭐ Worked great! *by B***N on March 12, 2026* Seemed to work extremely well as a base for our Grasscloth project. We used several coats of this primer. ### ⭐ Product separated and pretty much unusable *by T***M on February 14, 2025* Most of the one-star reviews here are for damaged shipping; they seem to have solved that problem by taping the can shut so it doesn’t open in transit. Mine arrived fine. HOWEVER, when I opened the can to use it, the product was separated - fluid on top and really thick paste below. Completely unusable as it was. I got a drill powered paint mixer and mixed it for nearly 30 min, which got it at least mixed, but still very lumpy. When applied to the wall, it left thick gobs and lumps everywhere. I diluted with some water, that got it a bit smoother, but still left little lumps all over. Ended up diluting way more than recommended just to get it to a usable consistency that could at least be painted or rolled on. Maybe I just got a bad batch or something, but as it was, this stuff was awful. ## Frequently Bought Together - ROMAN PRO-977 White Wallpaper Primer - Pigmented Acrylic Primer for Wallcoverings and Home Improvement, Water-based - 1 Gallon, White - Roman PRO-880 Wallpaper Adhesive & Paste for Any Wallcovering - Ultra Clear Strippable, 1 Gallon(330 sq. ft) - ROMAN’s Wallpaper Smoothing Tool for Home Improvement, Wallpaper Smoother for Installation, 7.75-Inch Wide, Plastic, White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/22780478-pro-977-ultra-prime-wallpaper-primer-water-based-white-1](https://www.desertcart.jp/products/22780478-pro-977-ultra-prime-wallpaper-primer-water-based-white-1) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-03*
