What are common mistakes in wallpaper removal

Tackling wallpaper removal can seem straightforward, but it's a job riddled with potential pitfalls that can turn a weekend project into a frustrating ordeal. From damaging your walls to making a mess, there are several common mistakes that homeowners frequently make. Understanding these errors beforehand can save you a lot of time, effort, and even money.

1. Not Properly Preparing the Room

This is perhaps the most overlooked step and can lead to significant cleanup headaches.

Not protecting floors and furniture: Wallpaper removal is messy. Glue, water, and bits of paper will inevitably end up on your floors and surrounding furniture. Failing to cover everything adequately with plastic sheeting or drop cloths is a recipe for a time-consuming cleanup.
Not turning off electricity: If you're working in an area with outlets or light switches, it's crucial to turn off the power to that circuit at the breaker box. Water and electricity are a dangerous combination.
Not removing fixtures: Small things like outlet covers, light switch plates, and even decorative trim can get in the way and become damaged if not removed.

2. Using the Wrong Tools or Techniques

The methods and tools you choose can make a huge difference in how easily and effectively you remove wallpaper.

Just trying to peel it dry: Many wallpapers are not designed to be peeled dry. This can tear the paper, leaving the backing (the paper layer) stuck to the wall, which is much harder to remove.
Soaking the walls too much: While water is often necessary, over-saturation can damage drywall, causing it to become soft and crumbly. It can also seep into the wall cavity.
Using harsh chemicals without testing: Strong chemical strippers can be effective, but they can also damage paint, wood trim, or even the wall surface itself if not used correctly or if the wall is not properly prepped. Always test in an inconspicuous area first.
Scraping too aggressively: Using a metal scraper with too much force can goude the drywall or plaster underneath, requiring significant patching later.

3. Not Identifying the Type of Wallpaper

Different types of wallpaper require different removal strategies.

Assuming all wallpaper is the same: Vinyl wallpaper, fabric-backed wallpaper, and traditional paper wallpaper all have different adhesives and backing materials, meaning they won't all come off with the same method. For example, vinyl wallpapers often have a top layer that needs to be removed first to expose the porous paper backing.
Not testing for strippable wallpaper: Some modern wallpapers are designed to be "strippable," meaning they peel off in large sheets without needing water or chemicals. Trying to soak a strippable wallpaper can be a waste of time and effort.

4. Inadequate Steaming Techniques

Wallpaper steamers are powerful tools, but improper use can be ineffective or damaging.

Holding the steamer in one spot for too long: This can lead to over-saturation of the drywall and potential damage.
Not allowing enough steaming time: Conversely, not steaming long enough means the adhesive won't soften, and the wallpaper will be difficult to remove.
Steaming areas you've already stripped: Once the wallpaper is off, there's no need to steam the exposed wall.

5. Forgetting About the Adhesive

Even after the wallpaper is off, the adhesive residue can be a significant problem.

Not cleaning off all the glue: Leftover adhesive will prevent new paint or wallpaper from adhering properly and can create a sticky, uneven surface.
Not using the right cleaning solution: A simple rinse might not be enough. Specialized adhesive removers or a solution of hot water and a degreaser or TSP substitute are often necessary.

6. Rushing the Process

Wallpaper removal is rarely a quick fix. Impatience is a common enemy.

Skipping steps: Trying to cut corners, like not removing stubborn bits of paper or not cleaning the adhesive thoroughly, will only create more work down the line when you need to paint or re-wallpaper.
Not allowing the walls to dry completely: If you plan to paint immediately after removal, ensure the walls are thoroughly dry. Moisture can lead to paint peeling or bubbling.

By being aware of these common mistakes and preparing accordingly, you can make the wallpaper removal process much smoother and more successful, leading to a beautifully prepped wall ready for its next transformation.

Frequently Asked Questions (FAQ)

How do I know if my wallpaper is strippable?

You can test for strippable wallpaper by lifting a corner or seam with a putty knife and gently trying to peel it away. If it comes off in large sheets without leaving much behind, it's likely strippable. If it tears easily or leaves a paper backing, it's not. For stubborn wallpaper, a wallpaper scoring tool can help determine if it's strippable by allowing water or stripper to penetrate.

Why is it important to remove all the old adhesive?

Old wallpaper adhesive is sticky and can prevent new paint or wallpaper from adhering properly to the wall. It can also create an uneven surface, making your new finish look unprofessional. It's crucial to clean the walls thoroughly to ensure a smooth, long-lasting finish.

What's the best way to protect my floor and furniture?

Use heavy-duty plastic sheeting or canvas drop cloths. Tape them securely to the baseboards and edges of furniture. Overlap seams to prevent any leaks. For furniture, it’s best to move it entirely out of the room if possible.

Can I just paint over the old wallpaper?

Generally, it's not recommended. Painting over wallpaper can lead to peeling, bubbling, and an uneven finish as the wallpaper adhesive loosens over time. It also makes future wallpaper removal much more difficult. It's always best to remove the wallpaper completely before painting.
