Prepare the space: remove furniture, cover the floor, and tape off electrical outlets
Stripping wallpaper that has been painted over can be a challenging and time-consuming task, but with the right preparation and techniques, you can achieve success. Here are some detailed instructions to prepare the space before you begin the stripping process:
Remove Furniture
It is advisable to remove all furniture from the room to create a clear and spacious working area. If removing all the furniture is not feasible, consider moving the pieces to the centre of the room and covering them with drop cloths or sheets. This will protect your furniture from any paint chips, strips of wallpaper, and dust that will be generated during the stripping process.
Cover the Floor
Covering the floor is an essential step to protect it from water, debris, and any chemicals used in the stripping process. Use drop cloths, tarps, or plastic sheeting to cover the entire floor area. This protective layer will catch the falling debris and make cleanup easier.
Tape Off Electrical Outlets
Before starting work, ensure that the electricity in the room is turned off for safety reasons. Tape off any electrical outlets, switch plates, and cover or remove outlet covers. This will prevent moisture or chemicals from entering the outlets and causing damage or electrical hazards. It will also make it easier to strip the wallpaper from underneath these areas.
Additionally, it is recommended to open windows for ventilation, especially if you are using chemical wallpaper strippers, as they may have strong odours. Proper ventilation will also help keep the workspace comfortable and reduce the concentration of dust and chemical fumes.

Score the wallpaper with a tool or stiff wire brush to create small holes
Removing wallpaper that has been painted over can be challenging, but with the right tools and techniques, you can achieve it without damaging the underlying wall. Scoring the wallpaper is a crucial step in this process.
Scoring the wallpaper involves creating small holes or perforations in the surface to allow moisture or stripping solutions to penetrate and soften the adhesive. This step is especially important when dealing with painted wallpaper because the paint forms an additional barrier that makes it harder for the solutions to absorb.
To score the wallpaper effectively, you can use a stiff wire brush or a specialised scoring tool. A scoring tool typically has small rotating wheels with teeth that can puncture the paper without damaging the wall underneath. When using a wire brush or scoring tool, apply gentle to medium pressure to create the small holes. Work across the entire area, being careful not to puncture the wall itself.
By scoring the wallpaper, you are breaking down the surface of the paint, which will enable your chosen stripping solution to absorb more effectively. This step is crucial in preparing the wall for the next steps of the wallpaper removal process.

Soak the wallpaper with a solution of water, vinegar, and fabric softener
Removing wallpaper that has been painted over can be a challenging task. To make the process easier, it is recommended to have all the necessary supplies ready before starting. One effective method for stripping painted wallpaper is to use a solution of water, vinegar, and fabric softener. Here is a step-by-step guide to help you through the process:
First, prepare the workspace by removing all furniture from the room or moving it to the centre and covering it with drop cloths. Cover the floor with drop cloths or tarps to protect it from water and debris. Turn off the electricity in the room and remove outlet covers and switch plates. Ensure proper ventilation by opening windows, as some wallpaper strippers have strong odours.
Before applying the solution, it is essential to score the wallpaper. Use a stiff wire brush or a specifically designed wallpaper-scoring tool to gently scratch the surface of the paint film. Be careful not to apply too much pressure to avoid damaging the underlying wall material. Creating small perforations in the wallpaper will help the solution penetrate and soften the adhesive.
Now, prepare the solution by mixing water, vinegar, and fabric softener in a spray bottle. You can also use a bucket and a sponge for larger areas. The ratio of fabric softener to water may vary, but a common mixture is one part fabric softener to three parts water. You can also add vinegar to the solution for added effectiveness.
Once the solution is ready, apply it generously to the scored wallpaper. Work in small, manageable sections to avoid overwhelming yourself. Allow the solution to soak into the wallpaper for several minutes. The vinegar and fabric softener will help break down the adhesive, making it easier to remove the wallpaper.
After the solution has had time to work, use a putty knife or paint scraper to gently peel away the softened wallpaper. Start from a corner and work slowly and evenly down the strip. Be careful not to apply too much force, as it can damage the wall. If you encounter stubborn areas, use a hairdryer or steamer to apply heat for about 60 seconds to loosen the adhesive further.
Repeat the process for all sections of wallpaper, reapplying the solution as needed. Removing wallpaper that has been painted over can be tedious and may require multiple attempts. Be patient and persistent, and don't be afraid to try different tools and techniques to find what works best for your specific situation.

Scrape off the wallpaper with a putty knife or scraper
Removing wallpaper that has been painted over can be a challenging task. The process can be time-consuming and messy, and there is a risk of damaging the wall. However, with the right tools, proper technique, and patience, it is possible to remove painted wallpaper without causing harm to the underlying wall.
One of the key tools you will need is a putty knife or scraper. This tool will be essential when it comes to scraping off the wallpaper by hand. Before you start scraping, there are several preparatory steps you should take to make the process more effective and efficient.
First, it is important to prepare the space. Remove all furniture from the room, or move it to the center and cover it with drop cloths. Cover the floor with drop cloths or a tarp to protect it from water and debris. Turn off the electricity in the room and remove outlet covers and switch plates. Opening the windows for ventilation is also recommended, as some wallpaper strippers have strong odors.
Next, you should determine the type of paint that has been used. This can be done by dabbing a small amount of nail polish remover onto a paper towel and rubbing it onto the paint. If the paint comes off on the towel, it is latex paint; if not, it is alkyd (oil-based) paint. Latex paint is water-soluble and will be easier to work with, while alkyd paint may require more effort and multiple attempts to release the paper.
Once you have determined the paint type, you can start the process of breaking down the paint and wallpaper surface to allow moisture or steam to penetrate. You can do this by scoring the wallpaper with a stiff wire brush, a spiked roller, or a specifically designed wallpaper-scoring tool. Apply gentle to medium pressure to create small holes or perforations, being careful not to damage the underlying wall.
Now that you have prepared the surface, you can start applying a stripping solution or using steam to loosen the adhesive. Work in sections, allowing the solution or steam to soften the adhesive. You can use a commercial wallpaper stripper, or make your own solution with hot water, vinegar, and fabric softener. Apply the solution generously to the scored wallpaper using a garden sprayer or a sponge and spray bottle.
Finally, it's time to scrape off the wallpaper with a putty knife or scraper. Use the tool to peel away the softened wallpaper. For stubborn areas, you may need to use an electric steamer or apply heat with a hairdryer to loosen the adhesive further. Hold the steamer plate against the wall for about 30 seconds before scraping again. Continue working in sections until you have removed as much wallpaper as possible.

Remove leftover adhesive with a cleaning solution and putty knife
Removing wallpaper that has been painted over can be challenging, but with the right tools and techniques, it can be done successfully. Once you have removed the majority of the wallpaper, you can focus on eliminating any leftover adhesive. This can be done with a cleaning solution and a putty knife, and here is how you can do it:
First, prepare your cleaning solution. You can opt for a store-bought chemical solution specifically designed for removing wallpaper adhesive, such as DIF liquid or gel wallpaper stripper. Alternatively, you can create your own homemade solution. A mixture of one part fabric softener to three parts hot water is effective, or you can try a solution of one-third vinegar to two-thirds warm water. Another simple option is to mix hot water with washing-up liquid, which will break down the glue.
Next, apply the solution to the areas of leftover adhesive. Use a sponge or a soft cloth to work the solution into the glue. If the glue is particularly thick, you may want to use a soft brush to help loosen it. Allow the solution to sit for a few minutes so it can effectively break down the adhesive.
Once the solution has been applied and given time to work, use a plastic putty knife to carefully scrape away the loosened adhesive. Be gentle to avoid damaging the wall surface. If necessary, apply the solution again and repeat the process until all the adhesive is removed.
After removing the adhesive, it is important to clean and prepare the wall for its next treatment. Use a wet rag to wipe down the wall, removing any residue. You may need to sand down any rough spots with fine-grit sandpaper and a sanding sponge. Once the wall is smooth and dry, you can apply a primer. An oil-based primer, such as INSL-X® Prime Lock Plus, is recommended to seal any residual adhesive and prepare the wall for painting.
