Renovating walls in Toronto’s homes, offices, and commercial spaces is a frequent need in our ever-changing city. Many property owners, designers, and contractors encounter a common dilemma: existing wallpaper that’s dated, damaged, or simply doesn’t fit the new vision for the space. As 2026 brings new trends and innovative finishes like Venetian Plaster to the forefront of interior design, the burning question remains: is it possible to plaster over wallpaper safely in 2026?

Understanding the Challenges: Wallpaper and Modern Wall Finishes

Wallpaper was once the go-to decorative wall treatment in Toronto homes and businesses. Now, more and more property owners are opting for luxurious options such as Venetian Plaster or decorative paints, transforming bland walls into stunning focal points. However, before starting your next interior project, it’s vital to assess whether you can apply plaster directly over existing wallpaper and achieve a lasting, professional look.

Is It Possible to Plaster Over Wallpaper Safely in 2026?

This question is more than a matter of convenience—your choice impacts the durability, beauty, and value of your property. The answer depends on several factors, and 2026 brings advancements in materials, but the fundamentals of sound wall preparation remain the same. Let’s break down the main considerations so you can make an informed decision for your Toronto property.

Why Consider Plastering Over Wallpaper?

• Time Savings: Removing wallpaper is labor-intensive and can cause wall damage, especially in older homes.
• Cost Efficiency: Skipping removal may reduce initial renovation expenses.
• Minimal Disruption: Ideal for busy commercial spaces and households seeking efficient transformations.

But is it the safest and most durable solution? Here’s what you need to know in 2026.

Key Factors: Can You Plaster Over Wallpaper?

1. Wallpaper Adhesion and Type

Not all wallpapers are created equal. In 2026, most Toronto walls have either:

• Vinyl wallpaper – Popular in kitchens, bathrooms, and commercial spaces, but offers a challenging surface for plaster.
• Paper-based wallpaper – More breathable but can become weak or peel under moisture.
• Textured or fabric wallpaper – Tricky to cover smoothly, risks air pockets and uneven finish.

The key consideration is how solidly the wallpaper is bonded to the wall. Any loose edges, bubbling, or peeling could spell disaster after plaster application, causing cracking or entire sections to fall off as moisture or plaster weight severs the wallpaper’s grip.

2. Wall and Room Conditions

Toronto’s climate fluctuates from freezing winters to humid summers, so moisture and temperature play significant roles. Plaster needs to bond to a solid, clean, and dry surface. If the wallpaper hides underlying damage like mold, crumbling plaster, or uneven drywall, the final finish suffers—and may not meet the high standards of 2026 design.

3. Plaster Material Advancements in 2026

Modern plaster products, such as those offered by venetianplastershop.ca and Giorgio Graesan Italy, are more forgiving than their predecessors, boasting improved adhesion, breathability, and flexibility. However, these innovations are never a substitute for best preparation practices. Even with top-quality Venetian Plaster, wall integrity is the primary concern.

Professional Opinions: The Risks of Plastering Over Wallpaper in 2026

Ask any seasoned Toronto contractor or wall finishing specialist, and you’ll hear cautionary tales about plastering over wallpaper:

• Adhesion Failure: Even with primer, the wallpaper may eventually peel away under the weight of plaster.
• Bubbling & Seam Bleed-Through: High moisture in traditional and Venetian Plaster can soften wallpaper glue, causing bubbles or visible seams.
• Mould & Mildew: Water trapped between wallpaper and wall can lead to hidden mold growth, a major risk in Toronto’s humid months.
• Poor Aesthetics: Even the most skilled plasterer may struggle with an uneven base, resulting in a less-than-perfect final look.

When Might It Work?

Very occasionally, if wallpaper is exceptionally well adhered, absolutely flat, and composed of a simple paper with no vinyl or fabric, a professional may attempt a small, low-traffic area. In these situations, surfaces are thoroughly cleaned, scored, primed with advanced bonding primers, and then a thin skim coat may be applied. However, this is rarely recommended for large areas or main living and business spaces in 2026.

The Best Practices: How To Prepare Walls for Plastering in 2026

Step 1: Assess the Wallpaper Condition

• Check all edges, seams, and corners for lifting or bubbling.
• Press gently—does the wallpaper feel secure or does it move?
• Look for signs of hidden damage—previous leaks, stains, or strange odours.

Step 2: Remove Wallpaper (When Possible)

Though time-consuming, removing wallpaper is almost always the best route for lasting results. The process is as follows:

1. Use a scoring tool to create small holes that allow moisture to penetrate.
2. Apply a wallpaper remover or hot water with a sponge.
3. Gently scrape off with a putty knife.
4. Clean residual glue and let walls dry fully.

Step 3: Wall Inspection and Repair

• Patch cracks and holes.
• Sand rough areas smooth.
• Prime with high-quality acrylic primer—essential for Venetian Plaster and decorative paints.

Step 4: Apply Your Chosen Wall Finish

Venetian Plaster, decorative paint, or wallpaper from venetianplastershop.ca are all ideal choices once the wall is sound and primed.

Alternative Options for Wall Finishing in 2026

1. Skim Coat After Removal

After removing wallpaper, a skim coat of plaster creates a smooth, fresh base—perfect for subsequent finishes, especially Venetian Plaster.

2. Upgrade to Modern Wall Finishes

• Venetian Plaster – Luxurious, durable, and available in a range of stunning textures and colours.
• Decorative Paints – Add character and depth, from metallic sheens to matte finishes.
• Modern Wallpapers – High-quality, stylish, and easier to remove and maintain than older generations.

Common Questions: Toronto Wallpaper and Plaster FAQ 2026

1. Can I use any type of plaster over wallpaper?

No. Even modern, advanced plasters require a meticulously prepared base free of loose material. Using top-grade Venetian Plaster yields best results on a clean, primed wall—not over wallpaper.

Remove wallpaper fully, repair the base surface, prime, and complete with your chosen finish such as Venetian Plaster, decorative paint, or modern wallpaper.

4. Can Venetian Plaster hide wall imperfections?

Venetian Plaster can disguise minor flaws but will not hide major deficiencies or peeling wallpaper. Preparation is still essential for durable, flawless walls.

Conclusion: Achieve Safe, Stunning Walls in 2026

In summary, while it may sometimes be possible to plaster over wallpaper in 2026 with meticulous preparation, it is rarely considered safe or recommended for Toronto’s demanding styles and climate.
