Proper Wall Prep Before Wallpaper Installation in Denver Metro Area

Updated June 2025

Proper wall preparation is the foundation of a flawless wallpaper installation. In the Denver metro area, where homes range from new builds to historic renovations, skipping prep work can lead to poor adhesion, bubbling, and early peeling. This guide from EnjoyTheWall outlines how to prepare your walls step-by-step — whether you’re using vinyl, non-woven, or paper wallpaper.

🧼 Step 1: Cleaning the Surface

Start by removing any contaminants:

  • Dust, grease, and stains

  • Old wallpaper residue

  • Mold or mildew (if present)

🧽 Tip: Don’t skip behind radiators and in corners — these areas often collect grime that can affect adhesion.

🛠️ Step 2: Patching and Spackling

Inspect your wall closely:

  • Fill holes, dents, cracks, and chips

  • Use lightweight spackle or patching compound

  • Allow to fully dry before continuing

🎯 A smooth wall = no lumps or visible bumps under the wallpaper.

🪵 Step 3: Sanding the Wall

Once patched:

  • Lightly sand the surface to level out filler spots

  • Remove any peeling paint or rough areas

🪧 Safety Note: Wear a dust mask when sanding.

🎨 Step 4: Prime the Surface

Primer is not optional:

  • It seals porous surfaces like drywall and fresh plaster

  • Prevents excessive glue absorption

  • Helps wallpaper reposition easily during install

📊 Especially important if you’re working with paper wallpaper or delicate finishes.

🔏 Step 5: Level and Inspect

Use a level and straight edge before beginning:

  • Ensure the wall is vertical and even

  • Fix visible slopes or wavy drywall

  • Misaligned walls distort patterns

🔍 Even a small angle can ruin your pattern alignment.

⚠️ Many homeowners in Colorado, especially in older homes around the Denver metro area, encounter uneven drywall and hidden imperfections. That makes professional wall prep even more valuable.
