Removing wallpaper is a manageable DIY project that can significantly refresh a room's appearance. Success depends on proper preparation, the right tools, and a methodical approach to avoid damaging your walls. While the process requires patience, the average homeowner can complete it over a weekend with an estimated material cost of $50 to $100. This guide outlines the essential steps for effective and safe wallpaper removal.
Having the correct tools is critical for efficiency and wall protection. Before starting, gather the following items:
A wallpaper scraper is a tool with a wide, flat blade designed to lift and remove wallpaper without gouging the underlying drywall or plaster. Using a sprayer to apply the stripping solution is highly recommended, as it covers large areas more quickly and evenly than a sponge.
Proper preparation minimizes mess and protects your belongings. Begin by removing all furniture from the room or grouping it in the center. Cover the floor and any remaining furniture with plastic sheeting or canvas drop cloths to protect against drips and debris. Next, remove all switch plate covers and outlet covers. Use masking tape to cover any exposed electrical outlets to prevent moisture from entering them.
Yes, testing a small, inconspicuous area is a crucial first step. This test determines the wallpaper type and the adhesive's strength, informing your strategy. Gently lift a corner of the wallpaper with a scraper. If it peels away easily, you may be able to use a dry-stripping method. If it resists or tears, you will need to use a liquid solution to loosen the adhesive. Older homes may have multiple layers of wallpaper or a stubborn adhesive known as mastic, which requires more intensive treatment.
After testing, apply the stripper solution according to the manufacturer's instructions. For homemade solutions, a common mix is equal parts hot water and white vinegar or a small amount of liquid fabric softener in hot water. Using a sprayer, saturate a manageable section of the wall (about 4x4 feet). Allow the solution to penetrate the wallpaper for 15-20 minutes, reapplying if the surface dries out. For vinyl wallpapers, lightly scoring the surface with a perforation tool helps the solution penetrate the waterproof layer and reach the adhesive underneath.
| Removal Method | Best For | Estimated Cost | Key Consideration |
|---|---|---|---|
| Solvent/Solution | Most common wallpapers | $15 - $30 | Effective on standard adhesives; requires soaking time. |
| Steam Stripper | Multiple layers, stubborn adhesive | $50 - $75 (rental) | Faster but risks damaging drywall if used incorrectly. |
Once the solution has soaked in, start scraping from the bottom of the section upward. Use a wide scraper and keep the blade at a shallow angle to the wall. Apply gentle, consistent pressure; forcing the scraper can gouge the wall. If the wallpaper doesn't come off easily, re-wet the area and wait another 10-15 minutes. Patience is key. As you work, dispose of the wet wallpaper strips in a heavy-duty trash bag to keep the area clean.
After all wallpaper is removed, a residue of wallpaper paste often remains. Mix a solution of warm water and a few drops of dish soap in a bucket. Using a sponge, wash the walls thoroughly to remove all adhesive. Rinse the walls with clean water to eliminate any soapy film. Allow the walls to dry completely for at least 24 hours before proceeding with painting or new wallpaper. Inspect the walls for any imperfections; small holes or cracks can be filled with spackling paste, and a slightly damaged surface may require a skim coat (a thin layer of joint compound) to create a perfectly smooth base.
Successfully removing wallpaper hinges on methodical preparation, using the right tools, and allowing ample time for the solution to work. Testing an inconspicuous area first prevents unforeseen complications, and a thorough final cleaning ensures a professional-quality finish for your next decorative project.
