Home » The importance of properly preparing walls
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.

ToggleStart 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.
Read more on the problems of installing peel-and-stick wallpaper if surface prep is skipped.
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.
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.

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.
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.
Skimping on prep creates long-term issues:
✨ Better adhesion = no bubbles or edge curling
🚪 Professional finish = clean look
⏱ Longevity = your wallpaper lasts for years
