Using traditional wallpaper paste on peel and stick wallpaper is a bad idea. Peel and stick wallpaper has its own adhesive on the back, designed to stick directly to a smooth, clean surface. The paste is not meant to be used with this type of material and will likely ruin both the wallpaper and the wall underneath.
Why paste doesn’t work with peel and stick
Peel and stick wallpaper, also known as “removable wallpaper,” relies on a strong, pre-applied adhesive. When you peel off the backing paper, that sticky surface is ready to bond to your wall. Adding wallpaper paste introduces a wet, chemical layer that interferes with this original adhesive. Instead of helping it stick, the paste can:
- Break down the wallpaper’s adhesive backing, making it lose its stickiness.
- Create a slippery surface, causing the wallpaper to slide around during application and making it difficult to position correctly.
- Soak into the wallpaper material, potentially causing it to stretch, tear, or become discolored.
- Leave behind a sticky, pasty residue on your walls that is much harder to clean than the wallpaper’s original adhesive.
- Damage the drywall or paint underneath, especially if the paste is strong or left on for a long time.
The beauty of peel and stick wallpaper lies in its simplicity and ease of removal. Adding paste negates these advantages and creates a mess that is difficult to fix.
Understanding traditional wallpaper and paste
Traditional wallpaper requires a separate adhesive, typically a starch-based or vinyl-specific paste, to attach it to the wall. This paste is applied either to the back of the wallpaper or directly to the wall surface, depending on the type of wallpaper and paste. The paste acts as the primary bonding agent, allowing the paper to adhere and stay in place through the drying process.
The composition of traditional wallpaper is also different. It’s often made of porous materials that can absorb the paste and allow it to set properly. Peel and stick, on the other hand, is usually made of vinyl or a vinyl-coated material that has a non-porous surface and a self-adhesive backing.
Surface preparation for peel and stick is key
The success of peel and stick wallpaper depends almost entirely on proper surface preparation. Unlike traditional wallpaper where paste might help fill minor imperfections, peel and stick needs a smooth, clean, and dry surface. Here’s what you need to do:
- Clean the walls: Use a mild soap and water solution or a sugar soap cleaner to remove any dirt, grease, or grime. Pay special attention to areas around light switches and in kitchens where cooking oil can accumulate.
- Dry thoroughly: Ensure the walls are completely dry before applying the wallpaper. Moisture can interfere with the adhesive.
- Smooth the surface: Fill any holes or cracks with spackle and sand them smooth. Minor imperfections can sometimes show through thin peel and stick wallpapers.
- Test on an inconspicuous area: If you’re unsure about your wall surface or its finish (e.g., glossy paint), test a small piece of the wallpaper in a hidden spot. Wait 24 hours to see how it adheres and if it removes cleanly.
- Avoid certain paints: Matte or eggshell finishes are best. High-gloss or satin paints can prevent the adhesive from bonding effectively. If you have glossy paint, you might need to lightly sand it or apply a primer.
When might you be tempted to use paste?
You might think about using paste if:
- The wallpaper isn’t sticking well: This is almost always a sign of poor surface preparation or a faulty batch of wallpaper, not a reason to add paste. Re-clean and ensure the surface is smooth and dry.
- You’re trying to reposition a section: Peel and stick is repositionable, but only for a short time after application. If it’s been on the wall for a while, it might be adhering too strongly, and trying to peel it off to reapply paste would be counterproductive.
- You have leftover paste: Resist the urge to use up old supplies. The products are designed to work together.
If your peel and stick wallpaper isn’t adhering properly, the problem lies elsewhere. For detailed advice on installation, check out guide to applying peel and stick wallpaper.
What if I accidentally used paste?
If you’ve already applied paste to your peel and stick wallpaper, here’s what you can try, though success isn’t guaranteed:
- Gently remove the wallpaper: Try to peel off the wallpaper as carefully as possible. You might need to use a putty knife or scraper to help lift edges, but be cautious not to gouge the wall.
- Clean the residue: You’ll likely have paste residue on both the wallpaper (if you plan to reuse it, which is unlikely) and the wall. Use a damp cloth or sponge to wipe away as much paste as possible. For stubborn residue, a mild cleaner might be necessary.
- Repair the wall: Once the wall is clean and dry, you may need to repair any damage caused by the paste or the removal process. This could involve sanding, patching, or priming.
- Let it dry completely: Ensure the wall is bone dry before attempting to apply new wallpaper (peel and stick or traditional).
This process can be time-consuming and frustrating. It’s far better to avoid using paste altogether.

Alternatives for traditional wallpaper users
If you prefer the look and feel of traditional wallpaper and are comfortable with the application process, then using wallpaper paste is the correct method. You’ll need to ensure:
- The wallpaper is designed for paste: Check the product details.
- You have the right paste: Use a paste recommended for your specific wallpaper type (e.g., vinyl, paper, fabric).
- Proper paste application: Follow the manufacturer’s instructions for applying the paste to the paper or wall.
- Surface preparation: Even with paste, a clean, smooth wall is essential for a professional finish.

Conclusion: Stick to the manufacturer’s instructions
In summary, you absolutely cannot and should not use wallpaper paste on peel and stick wallpaper. The pre-applied adhesive is specifically designed to work without any additional wet glues. Using paste will likely lead to a failed installation, damaged walls, and wasted materials. Always follow the manufacturer’s guidelines for the specific product you are using to ensure the best results.
