Review: Very easy to use and clean up - I ordered this to help adhere pre-pasted wallpaper to paneling, after which I mounted on the ceiling of my entry. Sounds strange, but it was paintable, textured wallpaper that looks just like ceiling tiles and was cheaper than buying ceiling panels. I tried just using the wallpaper and water method like the instructions said, but the wallpaper didn't stick very well and was flimsy once it got wet. So here's what I did: I poured some of this wallpaper adhesive into a paint pan and added some water to make it a little more runny. I didn't think it needed to be quite as thick as it was - kind of a cross between Elmer's school glue and rubber cement. This is totally clear and like a gel. I then used a 4" paint brush and brushed the adhesive on the paneling in small sections, pressing the wallpaper on as I went to smooth out bubbles or wrinkles. I did not wet the wallpaper first. It worked great! I could reposition the wallpaper by lifting it up and moving it slightly and then pressing it down again, and it did not rip the wallpaper like it had when I was using only water. I let it sit for a few hours (I didn't have the paneling on the wall at this time, it was laying down on sawhorses). After a few hours I set the panels up on edge propped against the wall and let them dry overnight. The next day I installed the paneling on my ceiling, and it turned out very good. The wallpaper stuck and I now have a textured ceiling, ready to paint. Cleanup was very easy - the glue washed out of my paint brush with simply warm water (although I added some dish soap just to make sure), and it wasn't sticky or anything after the brush was dry. You can't tell I used the brush to apply glue. Same with the paint pan, rinsed out with warm water. I also like that this glue is clear and dries clear. I got a bit of glue on the wrong side of the wallpaper and it dried clear and you can't tell that there is glue there. I found this very easy to use, I didn't use the whole gallon (although I may have if I hadn't mixed it with water), and would definitely recommend this to make ANY wallpapering job so smoother. Much easier than the dip in water method. Review: Can't say enough good things! - I'm a seasoned DIYer, I've hung peel and stick wallpaper before. Never had I hung real wallaper that needed paste. Wallpaper is expensive so I was very worried about hanging it. I used this paste and it was soooo easy. It has harly any odor, the texture is similar to yogurt and it goes on very well. I rolled It onto the wall like paint and then hung the wallpaper up. It was so easy to do, and the if you put enough paste on the wall you have time to manipulate the wallpaper to where it needs to be with minimal struggle. It doesn't dry so fast that it's irritating and it's water clean up, so wiping up paste from the edges of the wallpaper was a breeze. I will definitely be buying this product again. ## Features - VERSATILE - Ideal for installing medium-weight to heavyweight wallpaper, such as vinyl and non-woven - HEAVY DUTY CLEAR - Provides extra tack to hang heavier weight wallpaper, like commercial vinyl and wall carpet - EASY TO USE - Applies easily with a paint roller, brush, or pasting machine - EXCELLENT COVERAGE - Covers approximately 280 square feet per gallon - enough to hang up to 5 double rolls of wallpaper - MADE IN USA - Proudly made in Calumet City, Illinois ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000I1VDPW | | Best Sellers Rank | #5,704 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #3 in Wallpaper Adhesives | | Brand | Roman | | Brand Name | Roman | | Color | Clear | | Compatible Material | Wallpaper | | Container Type | Pail | | Customer Reviews | 4.6 out of 5 stars 2,127 Reviews | | Global Trade Identification Number | 00017104113017 | | Included Components | Roman 011301 PRO-838 1 gal Heavy Duty Wallpaper Adhesive, Clear | | Item Form | Liquid | | Item Package Quantity | 1 | | Item Type Name | Roman 011301 PRO-838 1 gal Heavy Duty Wallpaper Adhesive, Clear | | Item Weight | 16 ounces | | Manufacturer | Roman Decorating Products | | Material | Modified Starches | | Material Type | Modified Starches | | Model | 011301 | | Number of Pieces | 1 | | Part Number | 11301 | | Specific Uses For Product | Wallpaper Installation | | UPC | 017104113017 | | Unit Count | 128 Fluid Ounces | | Viscosity Level | Medium | | Volume | 1 gallons | | Water Resistance Level | Not Water Resistant | ## Product Details - **Brand:** Roman - **Color:** Clear - **Item Form:** Liquid - **Material:** Modified Starches - **Specific Uses For Product:** Wallpaper Installation ## Images ![PRO-838 Heavy Duty Clear - Image 1](https://m.media-amazon.com/images/I/81C--ZKucwL.jpg) ## Questions & Answers **Q: Can I apply this to a painted smooth masonary wall?** A: I wouldn't think its an issue. I used it over a textured/painted wall and it worked great. **Q: Works for non-woven wallpaper ??** A: This wallpaper adhesive did not work as heavy duty to me. It should work on any wallpaper. It goes on pretty wet. The old thing is you can move the paper and realign, if needed probably for a good 30 mins after you place it. **Q: do I have to prime my wall first?** A: Just a thought, if it is new wallboard and if you think you might ever want to paint that wall it would be better to prime it so that the glue doesn't soak into the wallboard. Then when you take the wallpaper down you won't pull hunks of wallboard out. **Q: Is this a vinyl adhesive** A: Not sure, I use this for heavier wallpaper and will never use anything but this ever. Its amazing!!! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very easy to use and clean up *by S***N on October 28, 2020* I ordered this to help adhere pre-pasted wallpaper to paneling, after which I mounted on the ceiling of my entry.

The mural is heavy vinyl and did not come pre-pasted. I had never installed wall paper that needed a brush/roll-on adhesive, but this went swimmingly well. A little bit of a learning curve to know how much is enough and how much is too much, but after the first two strips, the rest was a breeze. tacky enough that the paper doesn't unroll and still able to move it a little to get the pattern and edges aligned just right. I would definitely recommend this product for installing medium to heavy weight wall paper. ## Frequently Bought Together - ROMAN PRO-838 Heavy Duty Clear Wallpaper Adhesive, for Commercial Weight Wallcoverings, Wall Carpet, Non-Wovens, and More, 1 Gallon (300 sq. ft.) - WRAPXPERT Wallpaper Smoothing Tools,Wallpaper Tool Kit with Squeegee Smoother,Seam Roller,Wallpaper Brush for Wallpaper Hanging,Contact Paper,Vinyl Application,Wallpaper Paste --- ## 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/14470648-pro-838-heavy-duty-clear](https://www.desertcart.jp/products/14470648-pro-838-heavy-duty-clear) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-27*
