What surfaces can I apply the wallpaper to?
You can apply geometric wallpaper to many smooth and clean surfaces, but not all surfaces are suitable. Here’s a clear and helpful guide on what surfaces you can apply wallpaper to—especially peel-and-stick or traditional types like those from The Comfy Mart:

✅ Best Surfaces for Wallpaper
Painted Walls

Smooth, dry, and clean painted walls are ideal.

Satin, eggshell, or semi-gloss paints work best.

Make sure there’s no dust, grease, or loose paint.

Primed Drywall

Fresh drywall must be primed first for the wallpaper to stick properly.

Use a wallpaper primer or sealer for the best results.

Wood (Smooth Plywood or MDF)

Clean, sanded wood panels can hold wallpaper well.

Avoid rough or untreated wood.

Glass and Mirrors

Peel-and-stick wallpapers work well on glass and mirror surfaces if they are clean and dry.
