How to Remove Wallpaper Glue?

Wallpaper was once a very popular way to cover walls as a home improvement interior style, but its popularity has gone down a bit. Taking down old wallpaper to get back to painted walls is now more common than putting up new wallpaper.

Wallpaper is hard to take off, especially in older homes where there may be layer after layer of wallpaper stuck together with dried glue that must be taken off completely before the walls can be painted. If you want to put up new wallpaper, you must also get rid of all the old glue and plastic tarps.

Even though it is time consuming to remove wallpaper glue, the job can be done with just a little warm water and a few cleaning supplies or white vinegar.

Before Startin

Before you can remove all of the glue, you have to take down the wallpaper. The top layer of the wallpaper design is usually easy to peel off after this process, but some of the glue from the cellulose backing layer may keep some of it stuck to the wall.

So, one way to get rid of the glue is to scrub away some of the backing that is still stuck to the wall. If there is still a lot of backing material stuck to the wall, the job can get messy, so be patient and fill your bucket with fresh water and cleaning solution as needed, and keep trash bags and drop cloths handy.

Think about safety

Wallpaper glue removal uses a lot of water, so it’s important to cover floors and tape off electrical outlets and wall switches to prevent water damage or electrical short circuits.

Should you really clean the walls after taking down wallpaper?

Even though you might be tempted to skip removing the glue and go straight to the next step, you should know that you shouldn’t paint over wallpaper glue or put up new wallpaper to cover it up.

Most wallpaper glues, which are also called wallpaper paste or wallcovering adhesive, are made of water, just like most wall paints. Because of this, when you put paint over glue and mix the two together, the glue will get going again.

This will make a wall that is lumpy and uneven. Also, there is a chance that the paint won’t stick well enough to the surface underneath and will chip off over time.

This is also true if you put new wallpaper on top of old glue. If there is a lot of glue left on the wall, the new wallpaper might not stick well to the surface, and the wall might look uneven or the wallpaper might even come off soon after. Not what you’d want to happen, right?

Precautions for Removing Wallpaper Glue in Homes Built Before 1978

When dealing with wallpaper glue removal in a home built before 1978, safety should be your top priority. Here’s what you need to do to ensure a safe renovation process:

1. Test for Lead Paint: Before starting any removal, it’s crucial to test for lead paint. Use a reliable lead testing kit available at hardware stores to check all layers beneath the wallpaper. This helps identify potential hazards from older lead-containing finishes.

2. Protective Gear: If lead is detected, ensure you’re equipped with the right protective gear. Wear a high-quality respirator mask that filters lead particles, along with gloves and protective eyewear to prevent skin and eye contact.

3. Containment and Ventilation: Seal the area where you are working to prevent lead dust from spreading to other parts of the home. Use plastic sheets to cover floors and doors. Ensure proper ventilation by opening windows and using fans to direct any dust away from living spaces.

4. Wet Removal Method: Whenever possible, opt for a wet removal method. Dampen the wallpaper and glue to minimize dust release. This can make the glue easier to remove and reduce the risk of inhaling hazardous particles.

5. Avoid Sanding: Steer clear of sanding or scraping, which can release lead dust into the air. If sanding is unavoidable, use tools equipped with HEPA filters.

6. Safe Disposal: Dispose of all debris properly. Place any removed wallpaper, glue remnants, and protective materials in sealed, heavy-duty trash bags. Follow local regulations regarding the disposal of materials containing lead.

Clearly, taking these precautions can help ensure your wallpaper removal project is both safe and successful, especially in older homes with potential lead paint.

But don’t let that discourage you! Glue from wallpaper can be easy to get rid of if you know what to do and have the right tools.

Vinegar, baking soda, and soap can be used to get rid of wallpaper glue.

Using things like vinegar, baking soda, and soap from home to clean might be the most common way to clean. You can get these products very easily, but what’s more important is that they work very well. Here are some easy ways to get the job done.

Step-by-step process for removing wallpaper glue:

Mix hot water and dish soap in a bucket, then add one tablespoon of baking soda and one cup of vinegar for every 3-4L of water used. Soak the sponge in the solution, squeeze out the extra liquid, and tap the glue residue carefully.

Use a rag to wipe a small area of the glue. Use a putty knife to scrape off all of the leftover stuff. Use a clean cloth and circles to wipe the left solution off the wall.

For optimal results, consider incorporating a range of materials to tackle the stubborn wallpaper glue effectively:

• Dobie Sponges and Scour Pads: These are excellent for scrubbing without damaging the surface. They help in loosening the glue for easier removal.

• 100-Grit Sanding Sponges: Ideal for tougher spots where glue has dried and hardened. They provide the necessary abrasion to break down the stubborn adhesive.

• Microfiber Cloths: Once most of the glue is removed, these cloths are perfect for the final wipe-down, ensuring no residue is left behind.

Additional Tools

To complement the sponges and cloths, these tools will ensure a thorough job:

• Bucket of Hot, Soapy Water: Essential for rinsing sponges and keeping them effective throughout the process.

• Rubber Gloves: Protect your hands from the cleaning solutions and the sticky glue.

• Plastic Drop Cloths: Use these to cover the floors and keep your workspace clean.

• Press N’ Seal: Handy for sealing off outlets and switches to prevent any moisture or debris from entering.

• Paper Towels: Useful for quick clean-ups and absorbing excess moisture.

By incorporating these materials and tools, you’ll have a comprehensive kit ready to tackle any wallpaper glue challenge with efficiency and ease.

Alternative Method 1: Scrub and Sand

1. Spray and Scrub: Spray a small section of the wall with your cleaning solution and scrub with a Dobie scrubby sponge, which effectively tackles glue residue.

2. Sanding for Stubborn Spots: Follow up with a sanding sponge. This tool is particularly useful for stubborn areas, as it digs into the surface to remove glue.

3. Wipe and Check: Use a microfiber cloth to wipe the area clean and check for any remaining glue. Repeat spraying and scrubbing if necessary.

4. Final Touches: For remaining stubborn spots, spray again and scrub with a more abrasive pad, like a Scour Pad.

Alternative Method 2: Scrape and Sponge

1. Initial Scrape: Start by spraying a section with your solution and scraping the glue off with a putty knife. This helps remove large amounts before scrubbing.

2. Sponge Scrub: Spray the area again and scrub with a sponge to clean up the remaining glue.

3. Follow-up Sanding: Use a sanding sponge to catch any glue that remains.

4. Drying and Finishing: Wipe with a paper towel to ensure the area is dry and free of excess glue. Using a fresh towel each time helps maintain cleanliness.

Tip

Small batches of cleaning solutions are mixed so that the water stays hot. Pour the solution into a spray bottle and spray a section of the damaged wall as an alternative. Instead of a sponge and bucket, it might be better to use a spray bottle to reach high places and avoid drips and spills.

Pour hot water, 1 tablespoon of baking soda, or 4 tablespoons of fabric softener into the spray bottle. Use this mixture the same way you would use the vinegar and water solution.

Only put cleaning solution on a small part of the wall that you can remove in a few minutes. Be careful not to soak the paper facing of the drywall too much.

Prepping Walls for Painting After Wallpaper Glue Removal

Removing wallpaper glue is crucial for a smooth paint finish. Once you’ve stripped the wallpaper, follow these steps to ensure a perfect canvas for painting.

Sanding for a Smooth Surface

Start by sanding the walls with a 100-grit drywall sanding pad. This not only helps in removing stubborn glue traces but also smooths out any patches, giving you a fresh start.

Safety Tip: Always wear a respirator and goggles when sanding to protect yourself from dust. Remember, if your home is older, consider testing the glue for asbestos first.

Priming Your Walls

Selecting the right primer is crucial. Begin by testing a small area with a water-based primer. If it bubbles, it can indicate that glue remains. Use a putty knife to scrape off these areas, which will lift both glue and primer.

For better results on slick or glue-tainted surfaces, switch to an oil-based primer. These are designed for strong adhesion and typically handle leftover glue more effectively. Apply it evenly and resist the urge to overwork the wet primer; allow it to dry thoroughly between coats.

Additional Tips

• Primer Application Tip: Lay down the paint, then leave it undisturbed to dry fully before applying subsequent layers.
• Final Finishing: Apply two coats of primer for maximum coverage. Once dry, proceed with painting using a matte acrylic paint for a clean, professional finish.

With these steps, your walls will be ready to impress with a flawless coat of paint, just in time for any additional renovations.

Final Notes

Leave the windows open so that the wall can fully dry and there is no chance of mold growing later. By implementing these methods, you’ll find an approach that suits your tools and preferences while ensuring a clean, glue-free surface.

Transforming a Glue-Covered Wall into a Pristine Canvas

Preparing the Surface:
After tackling the sticky residue left by wallpaper glue, the key lesson I learned was patience in the painting process. Initially, it was crucial to apply paint and let it dry completely without prematurely rolling or cutting in next to the wet areas. This vital step prevents the paint from being pulled off, ensuring a smooth and even coating.

Priming for Perfection:
To create a flawless base, I applied two coats of Cover Stain primer. This method not only masked any remaining traces of glue but also laid the groundwork for a pristine, paint-ready surface. There’s a unique satisfaction that comes from seeing a wall prepped and ready for the final touch.

Finalizing the Finish:
The following day, with anticipation, I applied a single coat of matte acrylic paint in a classic white. This choice was not just a reflex but an intentional step to maintain a clean, fresh look after our labor-intensive preparation. The transformation was stunning, boasting walls that complemented the newly installed hardwood floors.

Reflecting on Choices:
Although initially uncertain about the color, the decision to start with white allowed me to embrace a fresh, blank canvas. While future changes in color are likely, for now, the subtle elegance of white encapsulates the effort and achievement of the entire process.

By methodically preparing the surface and selecting the right products, I achieved a seamless finish that stands as a testament to diligent preparation and thoughtful execution.
