Wallpaper can completely transform the look and feel of a room, adding personality and style. However, in order to achieve the desired result, it is important to prepare and install the wallpaper correctly. This article will provide a comprehensive guide to preparing and installing wallpaper, covering topics such as preparing the walls, choosing the right wallpaper, measuring the walls, gathering the necessary tools and materials, cutting and preparing wallpaper strips, applying wallpaper adhesive, hanging the first strip of wallpaper, aligning and matching patterns, trimming excess wallpaper, and maintaining the wallpaper for longevity.

Preparing Your Walls for Wallpaper Installation

Before you can begin installing wallpaper, it is crucial to properly prepare the walls. Start by cleaning the walls to remove any dirt, dust, or grease. This can be done using a mild detergent and warm water. Make sure to rinse the walls thoroughly and allow them to dry completely before moving on to the next step.

Next, inspect the walls for any holes or cracks. These should be filled in using a spackling compound or filler. Once the compound has dried, sand the walls to create a smooth surface. This will ensure that the wallpaper adheres properly and provides a flawless finish.

After sanding, it is recommended to apply a primer to the walls. This will help the wallpaper adhere better and prevent any stains or discoloration from bleeding through. Choose a primer that is specifically designed for wallpaper application and follow the manufacturer’s instructions for application.

Choosing the Right Wallpaper for Your Room

When choosing wallpaper for your room, there are several factors to consider. First, think about the style and purpose of the room. Is it a formal living room, a cozy bedroom, or a playful children’s room? The wallpaper should complement the overall style and create the desired atmosphere.

Next, consider the pattern and color of the wallpaper. Patterns can range from subtle textures to bold prints, so choose one that suits your personal taste and the style of the room. Additionally, consider the color of the wallpaper and how it will coordinate with the existing furniture and decor in the room.

Finally, decide on the type of wallpaper you want to use. There are various types available, such as vinyl, grasscloth, and fabric-backed. Each type has its own advantages and disadvantages, so research and choose the one that best fits your needs and budget.

Measuring Your Walls and Calculating Wallpaper Needed

Accurate measurements are crucial when it comes to calculating the amount of wallpaper needed for your walls. Start by measuring the height and width of each wall that you plan to wallpaper. Measure from floor to ceiling and from corner to corner, making note of any obstacles such as windows or doors.

Once you have the measurements, you can calculate the amount of wallpaper needed. Most wallpaper rolls come in standard sizes, typically 20.5 inches wide and 33 feet long. To calculate the number of rolls needed, divide the total square footage of the walls by the square footage of one roll. It is recommended to add an extra roll or two for pattern repeats and waste.

Gathering the Necessary Tools and Materials

Before you begin installing wallpaper, make sure you have all the necessary tools and materials. Some of the essential tools include a tape measure, utility knife, wallpaper smoother, wallpaper brush, and a straight edge. Additionally, you will need wallpaper adhesive, a paint roller or brush for applying the adhesive, a wallpaper tray or bucket, and a ladder or step stool.

When purchasing materials, it is important to choose high-quality products. This will ensure that the wallpaper adheres properly and lasts for a long time. Look for wallpaper adhesive that is specifically designed for the type of wallpaper you are using. Additionally, choose a wallpaper brush and smoother that are made of durable materials and have a comfortable grip.

Cutting and Preparing Wallpaper Strips

Once you have gathered all the necessary tools and materials, it is time to cut and prepare the wallpaper strips. Start by measuring and cutting the wallpaper strips according to the height of the walls. Add a few extra inches to the length to allow for trimming and adjustments.

To make the installation process easier, label each strip with a number or letter to indicate its position on the wall. This will help you keep track of the order and ensure that the pattern matches up correctly.

Before hanging the wallpaper, it is important to allow it to relax. This can be done by unrolling the wallpaper and letting it sit for a few minutes. This will prevent the wallpaper from shrinking or expanding after it is hung.

Applying Wallpaper Adhesive

Before applying the wallpaper adhesive, it is important to prepare it according to the manufacturer’s instructions. This may involve mixing the adhesive with water or allowing it to sit for a certain amount of time.

Once the adhesive is ready, use a paint roller or brush to apply it to the wall. Start at the top of the wall and work your way down, making sure to cover the entire surface evenly. Avoid applying too much adhesive, as this can cause the wallpaper to slide or bubble.

To avoid air bubbles and wrinkles, it is important to smooth out the wallpaper as you hang it. Use a wallpaper brush or smoother to gently press the wallpaper against the wall, starting from the center and working your way outwards. This will help remove any air pockets and ensure a smooth and seamless finish.

Hanging the First Strip of Wallpaper

Hanging the first strip of wallpaper is a crucial step, as it sets the foundation for the rest of the installation. Start by aligning the edge of the wallpaper with a plumb line or level, ensuring that it is straight and level. Use a wallpaper brush or smoother to press the wallpaper against the wall, starting from the center and working your way outwards.

To avoid crooked wallpaper, it is important to take your time and make adjustments as needed. If the wallpaper is not straight, gently peel it off the wall and reposition it. Use a straight edge or level to guide you and ensure that the wallpaper is aligned correctly.

Aligning and Matching Patterns

If your wallpaper has a pattern, it is important to align and match the patterns as you hang each strip. This will create a seamless and professional-looking finish. Start by aligning the pattern at eye level and use a straight edge or level to guide you.

To avoid gaps and overlaps, it is important to measure and cut each strip accurately. Take into account the pattern repeat and make adjustments as needed. If the pattern does not match up perfectly, you can use a sharp utility knife to trim the edges and create a seamless transition.

Trimming Excess Wallpaper and Finishing Touches

Once all the wallpaper strips are hung, it is time to trim the excess wallpaper and add the finishing touches. Use a sharp utility knife or wallpaper trimmer to trim the excess wallpaper at the ceiling and baseboards. Take your time and make precise cuts to ensure a clean and professional finish.

After trimming, go over the wallpaper with a wallpaper smoother or brush to smooth out any wrinkles or bubbles. Start from the center and work your way outwards, applying gentle pressure to remove any imperfections.

If desired, you can add wallpaper borders or trim to enhance the look of the room. This can be done using wallpaper adhesive or a double-sided tape. Make sure to align the borders or trim correctly and smooth out any air bubbles or wrinkles.

Tips for Maintaining Your Wallpaper for Longevity

To ensure that your wallpaper lasts for a long time, it is important to clean and maintain it properly. Use a soft cloth or sponge to gently wipe away any dirt or stains. Avoid using abrasive cleaners or scrub brushes, as these can damage the wallpaper.

Additionally, it is important to avoid direct sunlight and moisture, as these can cause the wallpaper to fade or peel. Use curtains or blinds to block out sunlight and make sure to keep the room well-ventilated to prevent moisture buildup.

If your wallpaper becomes damaged, it is possible to repair it. Small tears or punctures can be patched using a small piece of matching wallpaper and wallpaper adhesive. Simply cut out a patch that matches the pattern and size of the damaged area, apply adhesive to the back, and press it onto the damaged area. Smooth out any air bubbles or wrinkles and allow it to dry completely.


Properly preparing and installing wallpaper is essential for achieving a beautiful and long-lasting result. By following the steps outlined in this article, you can ensure that your wallpaper installation is a success.
