Why Wall Preparation Matters

Before you apply wallpaper—whether it’s embossed wallpaper, vinyl wallpaper, or peel and stick wallpaper—your wall needs to be properly prepared. Skipping this step leads to air bubbles, seams peeling, and a shorter wallpaper lifespan.

As top design websites like Wallpaper Direct and Graham & Brown recommend, proper wall preparation is the foundation of a flawless wallpaper application.

Step 1: Clean the Wall Surface

(Keyword: clean wall before wallpaper)

Even if your walls look clean, they likely have dust, grease, or other residue that can interfere with the wallpaper adhesive.

How to clean:

• Mix warm water and mild detergent.

• Use a sponge to clean the entire surface.

• Rinse with clean water and allow the wall to dry completely.

 Avoid heavy chemical cleaners—they can leave a residue that reduces adhesion.

Step 2: Repair Any Imperfections

(Keyword: wall repair before wallpaper)

Wallpaper clings to all surface textures, even unwanted ones. Fill nail holes, cracks, and dents before application.

Steps:

• Use spackle or wall filler.

• Let it dry fully.

• Sand smooth using fine-grit sandpaper.

This creates a smooth foundation for a seamless wallpaper finish.

Step 3: Remove Old Wallpaper

Do not apply new wallpaper over old wallpaper—it can cause bubbling and adhesion failure.

Best practices:

• Use a wallpaper steamer or stripping solution.

• Gently scrape with a wallpaper scraper.

• Remove leftover adhesive with a sponge.

According to Wallpaper Direct, always start with a clean slate.

Step 4: Sand Glossy or Semi-Gloss Walls

(Keyword: wallpaper glossy paint)

Glossy paints prevent proper adhesion.

How to prep:

• Use a sanding sponge to lightly roughen the surface.

• Wipe clean with a dry microfiber cloth.

Alternatively, apply a wallpaper primer made for glossy finishes.

Step 5: Apply Primer

(Keyword: wallpaper primer)

A wallpaper primer boosts adhesion and prevents dark paints from showing through light wallpaper.

Recommended primers:

• Roman PRO-977 Ultra Prime

• Zinsser Shieldz

Good to know: All Adawalls wallpapers are compatible with commercial-grade primers and adhesives.

Step 6: Check for Moisture or Mold

(Keyword: damp walls before wallpaper)

Moisture under wallpaper causes mold and reduces adhesion.

Quick test:

• Tape a piece of plastic wrap to the wall.

• After 24 hours, check for condensation underneath.

If moisture is present, resolve it before installing wallpaper.

Step 7: Gather Wallpaper Tools

Before you start applying wallpaper, have the right tools ready:

• Wallpaper adhesive (if not using peel and stick)

• Utility knife or scissors

• Measuring tape and level

• Smoothing tool or brush

• Seam roller

Adawalls wallpapers are designed for beginner and professional use alike, with easy handling and enhanced adhesion.
