Removing old wallpaper is an essential first step in any wall renovation. Whether you’re planning to paint or apply new wallpaper, clean and properly prepped walls are the key to lasting results. In this article, we’ll explain how to remove old wallpaper and prepare walls for renovation — quickly and correctly.
1. Identify the Type of Wallpaper
Start by figuring out what kind of wallpaper you’re working with:
- Paper wallpaper: comes off easily when wet
- Vinyl wallpaper: peel off the top layer dry, then soak the backing
- Non-woven (fiberglass): may come off in sheets or require water and scraping
2. Gather the Right Tools
- Wide and narrow scrapers or putty knives
- Spray bottle or sponge with warm water
- Wallpaper perforator or spiked roller (for moisture-resistant wallpapers)
- Dish soap or vinegar to help loosen adhesive residue
3. Step-by-Step Wallpaper Removal
- Peel off the top layer if the wallpaper is layered
- Soak the wall with warm water (optionally mixed with vinegar or a wallpaper remover solution)
- Let it sit for 10–15 minutes to soften the glue
- Scrape off the wallpaper from top to bottom using a scraper
- Clean the wall of any remaining glue and debris
4. Inspect and Repair the Walls
Once the wallpaper is removed:
- Look for cracks, dents, or mold spots
- Use filler or patching compound to fix damage
- Apply primer to ensure adhesion of new finishes
5. Final Prep for Painting or New Wallpaper
- For painting: surfaces should be smooth, clean, and dust-free
- For new wallpaper: minor imperfections are acceptable, but the wall should be clean and dry
