Applying self-adhesive wallpaper, also known as peel-and-stick wallpaper, is a relatively straightforward DIY project that can dramatically transform a room. Here's a step-by-step guide to ensure a smooth and professional-looking application:
1. Prepare Your Walls
- Clean the Surface: Thoroughly clean the walls with a mild soap and water solution to remove any dirt, dust, grease, or residue. Rinse with clean water and let the walls dry completely. This is crucial for proper adhesion.
- Smooth Imperfections: Fill any holes or cracks with spackle and sand smooth. Uneven surfaces will show through the wallpaper.
- Consider Priming: If your walls are porous, have been recently painted with a glossy paint, or are a dark color, consider applying a primer. Primer helps the wallpaper adhere better and prevents the underlying color from bleeding through. Let the primer dry completely according to the manufacturer's instructions.
- Remove Obstacles: Carefully remove outlet covers, light switch plates, and any other fixtures from the wall. Turn off the power to the area as a safety precaution.
2. Measure and Plan Your Layout
- Measure the Wall: Accurately measure the height and width of the wall you're covering.
- Calculate Wallpaper Needs: Determine how many rolls of wallpaper you'll need based on the dimensions of the wall and the roll size, factoring in pattern repeats. It's always best to order slightly more than you think you need to account for mistakes or future repairs.
- Plan the Placement: Consider how the pattern will align on the wall. Decide where you want to start and end, and how you'll handle corners or seams. Make a guide for your first piece using a level or plumb bob to ensure it's perfectly straight.
3. Apply the First Strip
- Cut the Wallpaper: Measure and cut the first strip of wallpaper, adding a few extra inches at the top and bottom for trimming (usually 2-3 inches).
- Peel and Position: Carefully peel back a small portion (about 6-12 inches) of the backing from the top of the wallpaper. Align the top edge of the wallpaper with your guideline and press it firmly to the wall.
- Smooth and Adhere: Slowly peel away the remaining backing, working your way down the wall, while smoothing the wallpaper with a smoothing tool or a clean, dry cloth. Work from the center outwards to prevent air bubbles.
4. Match Patterns and Repeat
- Align the Pattern: When applying subsequent strips, carefully align the pattern with the previous strip.
- Overlap or Butt Seams: Most peel-and-stick wallpaper is designed to be butted together (edges touching) rather than overlapped. Ensure the seams are as seamless as possible.
- Repeat the Process: Continue applying strips of wallpaper, matching the pattern and smoothing out any air bubbles, until the entire wall is covered.
5. Work Around Obstacles
- Windows and Doors: When you reach a window or door, apply the wallpaper over it. Then, use a sharp utility knife to carefully trim the wallpaper around the frame, leaving a clean edge.
- Outlets and Switches: Apply the wallpaper over the outlet or switch opening. Use a utility knife to carefully cut an "X" shape from corner to corner of the opening. Fold the flaps of wallpaper behind the wall and trim to fit. Replace the outlet cover or switch plate. Remember to turn off the power before working around electrical components.
6. Finish and Clean Up
- Trim Excess: Use a sharp utility knife to trim any excess wallpaper at the top and bottom of the wall, along the ceiling, and along the baseboard. A metal ruler or straight edge will help you make clean, straight cuts.
- Check for Air Bubbles: Inspect the wall for any air bubbles. If you find any, use a pin to prick the bubble and then smooth the wallpaper with your smoothing tool.
- Clean the Area: Wipe down the wallpaper with a damp cloth to remove any fingerprints or adhesive residue.
By following these steps, you can successfully apply self-adhesive wallpaper and achieve a professional-looking result.
