Before falling for the charm of a new panoramic wallpaper, it is imperative to go through an often dreaded step: wallpaper removal. Whether you are facing a thick vinyl inherited from the 90s or a multi-layered traditional wallpaper, the challenge is to efficiently remove the wallpaper without damaging the substrate (plaster, plasterboard, or skim coat). In 2026, the trend is towards environmentally and health-friendly methods, favoring natural solutions over aggressive chemical removers.
At Sunshinewall, we know that a perfect installation depends first and foremost on wall preparation. In this comprehensive guide, we will explore all techniques—from artisanal methods to professional steam removers—to ensure a stress-free transition to your new decor.
1. Site Preparation: The Golden Rule of Cleanliness
Removing wallpaper is a messy operation that generates a lot of moisture and sticky residue. Good preparation will save you hours of final cleaning.
1.1. Securing the Space
Start by emptying the room or gathering furniture in the center and protecting it with plastic sheets. Crucial point: Turn off the electricity at the circuit breaker for the circuits in the room concerned. You will be handling water near outlets and switches; safety should never be neglected.
1.2. Protecting the Floors
Use protective sheets with an absorbent side and a waterproof side. Wet wallpaper scraps tend to instantly stick to the floor once they fall. If you have parquet flooring, be extra careful with waterproofing to prevent water from seeping into the planks.
2. Identifying the Type of Wallpaper to Remove
The removal method depends directly on the nature of the current covering. Here's how to diagnose it:
- Classic Wallpaper: It absorbs water immediately. This is the easiest to remove with moisture.
- Vinyl Wallpaper: It has a waterproof PVC layer. Water cannot pass through it. It often needs to be scored or "peeled" in two steps.
- Non-Woven Wallpaper: This is the Holy Grail of renovation. Most modern non-woven wallpapers are "dry-strippable."
3. Method 1: The Natural Solution (Hot Water and Vinegar)
This is Sunshinewall's preferred method due to its zero cost and non-toxicity.
3.1. The Magic Recipe
Mix 50% very hot water and 50% white vinegar in a bucket or spray bottle. Vinegar helps dissolve old glue molecules. If the glue is particularly stubborn, you can add a tablespoon of dish soap, which will act as a wetting agent, allowing water to penetrate deeper.
3.2. The Soaking Process
Spray the wall generously starting from the top. Let it sit for 15 to 20 minutes. The secret is not to let the paper dry. If the paper absorbs everything, apply another layer. Once the paper blisters, insert a spatula under a seam and gently pull. If the paper resists, do not force it: re-wet it.
4. Method 2: The Steam Wallpaper Stripper
For large areas or multiple layers (the famous wallpaper glued over another wallpaper), steam is essential.
4.1. Advantages of Steam
The heat of the steam liquefies the glue almost instantly. It is a quick method but requires caution. Avoid leaving the steam plate too long in the same spot on a plasterboard wall (Placo), as you could soften the protective cardboard of the wall itself.
4.2. Pro Tip: The Perforator (Hedgehog)
If you have vinyl wallpaper, use a spike roller to perforate the plastic layer. This will allow the steam to penetrate to the glue. This is the essential step before installing a future high-quality panoramic wallpaper.
5. Special Case: Dry Stripping of Non-Woven Wallpaper
If you have already made the switch to a Sunshinewall product and wish to change patterns, you will love the removal step. Our non-woven wallpapers are designed for easy removal.
Simply grasp a corner at the bottom of the wall and pull firmly upwards. The strip comes off in one piece, without leaving any paper residue, and without needing a single drop of water. This allows you to switch from a Japanese style to a black and white ambiance in less than an hour.
6. After Removal: Preparing the Wall for New Installation
This is the most neglected step, yet the most important for the SEO of your decoration! A poorly prepared wall will show bubbles or bumps on your new wallpaper.
- Washing: Use lukewarm water with Saint-Marc detergent to remove all glue residue. A sticky wall will prevent the new glue from adhering properly.
- Patching and Sanding: If the spatula has left marks or if the wall has holes, fill them with a smoothing compound. Then sand with fine-grit sandpaper (180 or 240) to obtain a surface "smooth as a peach skin."
- Priming (Undercoat): We always recommend applying a white acrylic paint undercoat before installing a new floral wallpaper. This seals the background and greatly facilitates removal... in 10 years!
7. FAQ: Your Frequently Asked Questions
How do I remove glue residue from the wall? Use a mixture of hot water and baking soda. Scrub with a scouring sponge (non-abrasive side to avoid scratching the wall).
Can I glue my new wallpaper directly over the old one? We strongly advise against it. The moisture from the new glue can cause the old layer to peel off, creating irreversible bubbles. For a durable result, always start with a bare wall.
Conclusion: A New Beginning for Your Walls
Removing wallpaper is not a chore if you have the right tools and method. It is the foundational act of your future decor project. Once your walls are clean and smooth, the possibilities are endless. Whether you choose the strength of a forest or the brilliance of a green and gold wallpaper, your preparation work will guarantee a result worthy of a decor magazine.
