Choosing the Right Wallpaper for the Job
Choosing the right wallpaper is one of the best ways homeowners can avoid making common wallpapering mistakes. Picking the wrong type of wallpaper can lead to poor sticking, bubbling, peeling, or uneven finishes.
Since there's a range of options available, it’s important to match the wallpaper to both the room and the condition of the walls, as this makes the job easier and gives a cleaner, longer-lasting finish.
There are several types of wallpaper to choose from, and each has different features. Traditional paper wallpaper is often cheaper but it can be tricky to hang and can tear easily.
Vinyl wallpaper is stronger, easier to clean, and more resistant to moisture, making it ideal for kitchens and bathrooms. Textured wallpaper can add depth to a room and can hide small wall flaws, while peel-and-stick wallpaper is perfect for renters or anyone wanting a quick and easy redecorating project. For bold patterns or murals, non-woven wallpaper is a great option since it's tear-resistant and easier to remove or reposition.
Smooth, clean walls work best for most types of wallpaper. However, if the wall is slightly uneven or has small cracks, textured or thicker wallpaper can help hide these marks. For damp walls or areas with high humidity, it’s best to use waterproof or vinyl wallpaper that won’t lift or peel.
Glossy walls should be sanded lightly to help the wallpaper stick properly and freshly painted walls should be left to dry completely - any holes or damage should be filled in and smoothed out beforehand.
By choosing the right wallpaper, you can avoid many common problems. Whether you’re decorating one feature wall or an entire room, taking the time to match the wallpaper type to the wall condition will help you achieve a finish that lasts.
Preparing the Wall Surface Properly
Preparing the wall surface is one of the most important steps for achieving good results when hanging wallpaper. Many common wallpapering mistakes, such as bubbling, peeling, or uneven finishes, happen because the wall wasn’t properly prepared. Taking the time to prepare the surface helps the wallpaper adhere better and last longer.
Before applying wallpaper, the wall should be clean, dry, and free from dust or grease. Any marks, stains, or old adhesive can prevent the wallpaper from sticking properly. Additionally, if there's any mould or mildew, treat it with the right solution before going any further.
Rough or uneven areas on the wall should be sanded down to make the surface as smooth as possible to avoid bumps or lumps under the wallpaper. Holes and cracks should be filled with filler and sanded down once it's dry. A smooth surface provides a better finish and helps prevent tears or wrinkles during wallpapering.
Newly plastered or very absorbent walls can soak up the wallpaper adhesive too quickly. To avoid this, apply a primer or a wall sealer before hanging the wallpaper. This creates a better surface for the glue to bond to and helps with easy adjustments during application.
Glossy or painted walls should also be lightly sanded to help the adhesive grip better. If the wall has been painted with a dark colour, applying a light primer can stop it from showing through light or thin wallpaper.
By making sure the wall is clean, smooth, and properly sealed, homeowners can avoid many common wallpapering issues. Good preparation means the wallpaper will adhere better, stay in place, and look neat and professional.
Avoiding Air Bubbles and Creases
Air bubbles and creases are some of the most common problems homeowners face when hanging wallpaper. These issues can spoil the look of the wall and also lead to long-term issues like peeling or lifting edges. Bubbles and creases often form when the wallpaper isn’t applied evenly or if the adhesive isn’t spread properly.
In some cases, they appear because the paper has not been allowed to soak for the right amount of time before hanging. Rushing through the hanging process or not following the correct method can lead to poor results.
If bubbles or folds are left in the wallpaper, they can become more visible as the glue dries. This can ruin the overall appearance and the wallpaper might have to be removed and replaced.
To avoid air bubbles and creases, homeowners should always follow the instructions on the wallpaper and adhesive. After applying the wallpaper to the wall, use a wallpaper brush or smoothing tool to press it down gently from the centre outwards.
This helps push out any trapped air and keeps the surface flat. It’s also important to line up the edges properly before smoothing. Take your time to match patterns and make sure the paper is straight. Avoid pulling or stretching the wallpaper, as this can cause creases to form. By working slowly and carefully, you can stop bubbles and creases from forming.
Dealing with Corners and Edges
Corners and edges can be tricky areas when it comes to wallpapering. If these areas are not handled properly, they can cause creases, lifting edges, or poor pattern matching. Many wallpapering mistakes happen in these areas, but with the right steps, homeowners can achieve a smooth and professional-looking finish.
When wallpapering around an internal corner, never try to push a full strip into the corner. Instead, measure and cut the strip so that only a small section (about 1–2 cm) wraps around the corner. Then, start the next strip on the new wall, and slightly overlap the piece that wraps around - this method helps the wallpaper lie flat and reduces the risk of wrinkles or peeling.
For edges near ceilings, skirting boards, and door frames, make sure the wallpaper is firmly pressed into place before trimming. Use a smoothing tool to guide your cuts and always use a sharp knife to avoid tearing the wallpaper.
By taking care of corners and edges, homeowners can avoid many common wallpapering mistakes. Neatly trimmed and well-stuck wallpaper looks better and lasts longer. With patience, careful measuring, and the right tools, even difficult areas can be finished to a high standard.
