Common Wallpaper Installation Mistakes and How to Avoid Them

Installing wallpaper can transform a room, adding color, texture, and personality. However, even a small mistake can lead to a less-than-perfect finish. Here, we highlight some common wallpaper installation mistakes and offer tips on how to avoid them.

Neglecting Wall Preparation

One of the biggest mistakes is failing to properly prepare the walls. This step is crucial for ensuring the wallpaper adheres correctly and looks smooth. Always clean the walls to remove dust and grease, and consider applying a primer for better adhesion.

It's also important to repair any imperfections such as holes or cracks. Use spackle to fill in any gaps, and sand them smooth for a perfect surface.

Incorrect Measurements

Accurate measurements are essential for a seamless wallpaper installation. Measure the height and width of each wall to determine how much wallpaper is needed. Don't forget to account for pattern repeats, which can affect how much wallpaper you’ll require.

It's a good idea to purchase an extra roll to ensure you have enough material, especially if you are matching patterns. Always double-check your calculations before cutting the wallpaper.

Poor Cutting Techniques

Cutting the wallpaper incorrectly is a common mistake that can ruin the entire project. Always use a sharp utility knife or scissors for clean cuts. Ensure your cuts are straight by using a straight edge or level.

When dealing with patterns, align the design before cutting to maintain consistency across panels. This attention to detail will make the final look much more professional.

Improper Adhesive Application

Using the wrong adhesive or applying it unevenly can cause bubbles, wrinkles, or peeling. Always follow the manufacturer's instructions for the type of wallpaper you are using.

If using paste, apply it evenly across the entire back of the wallpaper. Let it sit for the recommended time to ensure proper adhesion. For peel-and-stick wallpaper, ensure the surface is smooth and clean before application.

Ignoring Air Bubbles

Air bubbles can be a frustrating issue when installing wallpaper. To avoid them, smooth the wallpaper from the center outward using a wallpaper brush or a plastic smoother. This technique helps push air out towards the edges.

If bubbles persist, gently lift the wallpaper and reapply. For stubborn bubbles, a small pinhole can release trapped air without noticeable damage.

Uneven Seams

Ensuring that seams are aligned and smooth is crucial for a polished look. Overlapping seams or leaving gaps can be quite noticeable. Carefully butt the edges of each strip together without overlapping.

Use a seam roller to press the seams flat, ensuring they are well-adhered. Be gentle to avoid squeezing out adhesive or damaging the paper.

A successful wallpaper installation requires attention to detail and careful preparation. By avoiding these common mistakes, you can achieve a beautiful finish that enhances your space. Happy decorating!
