Installing wallpaper can instantly transform a room, but proper application is key to a neat, long-lasting finish. Here are some essential wallpaper installation tips for homeowners.
1. Prepare the Wall Surface
- Ensure walls are clean, smooth, and dry.
- Remove old paint flakes, dust, or existing wallpaper.
- Fill cracks and holes with putty, then sand lightly for a smooth surface.
2. Measure and Plan Accurately
- Measure the wall height and width before buying rolls.
- Add 10–15% extra wallpaper to account for pattern matching and errors.
- Plan where patterns will start and end — center the design on the wall if possible.
3. Cut & Align Patterns Properly
- Cut strips longer than wall height to allow trimming.
- For patterned wallpaper, align motifs carefully for seamless joins.
- Use a sharp cutter or scissors to avoid jagged edges.
4. Apply Adhesive Evenly (for non-peel wallpapers)
- Use the recommended glue (paste-the-wall or paste-the-paper type).
- Spread adhesive evenly with a roller/brush, avoiding clumps.
- For peel-and-stick wallpaper, ensure backing is removed slowly to prevent air bubbles.
5. Smooth Out Air Bubbles
- Use a wallpaper smoothing tool or plastic spatula.
- Work from the center outward to edges.
- Avoid over-smoothing, which can stretch or tear delicate wallpapers.
6. Trim Edges Neatly
- Use a sharp utility knife to trim at the ceiling, floor, and corners.
- Replace blades often for crisp cuts.
- Seal edges near skirting boards or corners with extra adhesive if needed.
7. Handle Corners with Care
- For inside corners, overlap slightly and trim for a tight fit.
- For outside corners, wrap the wallpaper around with at least 2–3 cm extra for grip.
8. Maintain Proper Lighting During Installation
- Use bright lighting while installing to spot bubbles, misalignments, or glue smears.
9. Allow Proper Drying Time
- Avoid touching or pressing seams until fully dry.
- Keep the room ventilated but avoid direct fans or heat on fresh wallpaper.
10. Hire Professionals for Complex Designs
- For murals, textured, or fabric wallpapers, professional installation ensures precision and durability.
