Wallpaper can completely transform a room; adding texture, personality and style. But no matter how beautiful the design, the final result depends on one thing: how well the walls were prepped before installation. Skipping this step can lead to bubbles, peeling, or uneven application, especially in Florida’s humid climate.
At G&N Home Finish, we’ve seen it all and we know that professional preparation makes all the difference. Whether you’re a DIY enthusiast or planning to hire a pro, here’s how to get your walls ready for a flawless wallpaper finish.
Why Proper Wall Preparation Matters
Wallpaper needs a clean, smooth and stable surface to stick properly. Poor prep can cause:
- Adhesive failure
- Visible lumps or cracks beneath the paper
- Mold or moisture issues over time
- Shortened lifespan of the wallpaper
Especially in Florida Homes, where high humidity and salt air are common, proper wall sealing is essential to prevent peeling and bubbling.
Tools and Materials You’ll Need
Before you begin, make sure you have the following:
- Mild detergent and sponge
- A bucket of clean water
- Spackle or joint compound
- Putty knife
- Sandpaper or sanding block
- Level and straight edge
- Wallpaper primer or sealer
- Drop cloth and painter’s tape
Use a work light or flashlight to scan the wall surface; imperfections become easier to spot when lit at an angle.
Step-by-Step: How to Prep Walls for Wallpaper
-
Clean the Walls
Wipe down all surfaces with a sponge and mild soap to remove dust, grease, and any mildew. Rinse with clean water and let dry completely. -
Repair Any Imperfections
Use spackle or joint compound to fill nail holes, dents, or cracks. Let it dry, then sand smooth. This prevents bumps under the wallpaper. -
Sand the Surface
Even if your walls look smooth, lightly sand them to improve adhesion, especially if they’re glossy or semi-gloss. -
Check for Uneven Areas
Run a straight edge across the wall to detect any waves or dips. Fix as needed with compound and sand again. -
Apply Primer or Sealer
This step is critical. A wallpaper primer (sometimes called sizing) helps the adhesive bond evenly and makes future removal easier. For older walls or textured surfaces, a wall sealer is also recommended. -
Let Everything Dry
Ensure the surface is fully dry before applying any wallpaper. Florida’s humidity can extend drying time, so be patient.
