Applying wallpaper correctly transforms a room instantly, turning a plain wall into a statement of style and personality. Whether you are refreshing a single accent wall or redecorating an entire space, the process demands patience, precision, and the right preparation. This guide walks you through every step, from choosing the right materials to achieving a flawless finish that lasts for years.
Essential Tools and Materials for Success
Before you begin, gathering the correct tools eliminates frustration and ensures a smooth application. You need more than just paste and a brush; the right equipment makes the difference between a professional result and a messy re-do. Investing time in preparation also saves you from correcting errors later.
Here is a breakdown of the essential items you will need to complete the job efficiently:
Wallpaper paste (pre-mixed or powder)
Smoothing brush or plastic smoother
Utility knife or craft scissors
Measuring tape and level
Cutting mat and straight edge
Paint roller and tray for paste
Sponge or damp cloth for cleaning
Preparing the Walls is Non-Negotiable
Skipping wall preparation is the most common mistake DIY enthusiasts make. Old paint, dust, or uneven surfaces will show through the paper, causing bubbles, peeling, and a shortened lifespan for your new look. A smooth, clean, and dry canvas is the foundation of a perfect finish.
Follow these steps to ensure your walls are ready to accept the wallpaper:
Wash the walls with mild soap and water to remove grease.
Fill any holes or cracks with spackle and sand smooth.
Remove old wallpaper if necessary, using a steamer.
Apply a primer or sealer if the walls are porous or stained.
Measuring and Cutting the Paper
Accuracy in this stage prevents waste and keeps the pattern aligned. Measure the height of the wall, adding an extra 2 to 4 inches at the top and bottom. This overage allows you to trim the paper precisely without the risk of the strip being too short.
When dealing with patterned wallpaper, the cutting process becomes even more critical. You must account for pattern repeats to ensure the design flows seamlessly from one strip to the next. Lay the paper face down, mark your measurements, and use a straight edge and sharp utility knife for clean, precise cuts.
Applying Paste Evenly
The method you use to apply paste depends on the wallpaper type, but the goal remains the same: full, consistent coverage. For dry paste, mix it slowly with water until it reaches a smooth, creamy texture. Pre-mixed paste is ready to roll but requires careful handling to maintain an even coat.
Brush the paste onto the back of the paper, working from the center outward to avoid stretching the material. Fold the paper gently in a concertina or accordion style, allowing the paste to set for the recommended "booking" time. This folding process relaxes the paper, making it less likely to tear when you hang it.
Hanging the First Strip
The first strip sets the tone for the entire project, so take your time to align it perfectly. Use a level or a chalk line to mark a vertical guideline on the wall. This line acts as your reference, ensuring the wallpaper hangs straight and the pattern remains true.
Position the top of the strip slightly above the skirting board line, allowing for easy trimming later. Carefully unfold the paper and press it onto the wall, starting from the top and smoothing out any air pockets with downward strokes. A plastic smoother is ideal for this, as it glides smoothly without damaging the surface.
