Can You Wallpaper Over Damp Walls?
A Complete Guide by Adawall
Damp walls can be a homeowner’s nightmare—especially when you're excited about installing beautiful wallpaper to refresh your space. If you’re wondering, “Can I wallpaper over a damp wall?” the answer is: yes, but with extreme caution and the right preparation.
In this guide by Adawall, we’ll walk you through how to deal with moisture problems before applying wallpaper, the best types of moisture-resistant wallpaper, and expert tips to ensure your walls stay stylish and dry.
Why Moisture Is a Problem for Wallpaper
Before you grab your paste or peel-and-stick roll, it’s important to understand why damp walls and wallpaper don’t naturally get along.
Here’s why wallpapering damp walls can be risky:
-
Adhesion issues: Wallpaper paste or adhesive won’t stick properly to wet surfaces.
-
Mold growth: Trapped moisture behind wallpaper can encourage mold and mildew.
-
Peeling and bubbling: Over time, moisture can cause wallpaper to lift or bubble.
-
Damage to the wall and wallpaper: Constant exposure to humidity weakens both surfaces.
At Adawall, we’ve seen it all. And we know that proper surface prep is key to long-lasting, beautiful results.
Step-by-Step: How to Wallpaper a Wall with Moisture Issues
1. Diagnose the Source of Dampness
Before applying anything, find out where the moisture is coming from. Is it rising damp? A plumbing leak? Poor ventilation?
🛠 If the moisture is persistent or structural, we recommend fixing it completely before wallpapering.
2. Dry the Wall Thoroughly
Use dehumidifiers, fans, or open windows to dry the wall. Moisture meters (available at hardware stores) can help you check when it's truly dry.
3. Treat the Surface with a Mold-Resistant Primer
Apply a mold-resistant primer such as Zinsser Mold Killing Primer to prevent future problems. At Adawall, we always recommend priming for the best wallpaper adhesion.
4. Sand and Clean the Surface
Once dry, lightly sand the area to create a good surface for the wallpaper to stick. Wipe away dust with a damp cloth.
5. Use the Right Wallpaper Adhesive
If you're using traditional wallpaper, make sure to choose a strong, mold-resistant adhesive. We suggest Roman Pro-880 or a similar high-performance paste.
6. Install Moisture-Resistant Wallpaper
Choose wallpaper that’s designed for humid areas. At Adawall, our moisture-resistant vinyl wallpapers and non-woven options are perfect for bathrooms, kitchens, or basements.
Best Wallpaper for Damp Rooms
If you’re redecorating a bathroom, laundry room, or basement, opt for wallpapers that can handle humidity. Here are your best options:
-
Vinyl wallpaper – Extremely durable and water-resistant.
-
Fiberglass wallpaper – Often used in commercial spaces; mold and water-resistant.
-
Non-woven wallpaper – Breathable and less likely to trap moisture.
-
Adawall Peel-and-Stick Wallpaper – Easy to apply and remove, perfect for humid areas.
Real-World Tip: Use a Wallpaper Liner
Wallpaper liners, also known as lining paper, can create a moisture barrier and provide a smoother surface. Apply it before your main wallpaper for added protection.
