Easy Guide: How to Put Up Wallpaper with Paste Like a Pro

March 6, 2024

Transforming your space with wallpaper is a surefire way to add personality and flair to your home. But before you begin, knowing the right way to apply wallpaper with paste is key to achieving that seamless look. 

You might think that applying wallpaper is a task for professionals only, but with the correct type of adhesive and a few essential tools, you can do it yourself. Ready to give your walls a stunning makeover? Let's get started on how to put up wallpaper with paste.

Choosing the Right Wallpaper

When deciding on wallpaper, it's critical to weigh several factors to ensure the final outcome meets your expectations. Your choice will influence not only the aesthetic but also the ease of application and long-term maintenance. Here's what you need to consider:

  • Design Impact: A bold pattern can create a focal point, while a subtle design may add texture without overwhelming the space.
  • Room Usage: High-traffic areas might benefit from washable wallpapers, whereas living areas can indulge in more luxurious textures.
  • Lighting Conditions: Light plays a significant role in how wallpaper colours appear. Always view your sample in the room where it will be used.
  • Scale of Pattern: The size of the pattern should be in harmony with the size of the room and its features.
  • Pattern Match: Consider how easy it will be to match the pattern at the seams. A complex match may lead to more waste and a need for extra rolls.

Types of Wallpaper Available

Wallpapers come in a variety of materials and textures, each suited for different needs and preferences:

  • Vinyl Wallpaper: Highly durable and easy to clean, making it ideal for kitchens and bathrooms.
  • Non-Woven Wallpaper: Breathable fibres make it mould-resistant and a good fit for damp environments.
  • Grasscloth Wallpaper: Offers a natural texture and depth for a more organic feel, perfect for creating a serene atmosphere.
  • Foil Wallpaper: Reflective properties add brightness to a room but require a flawless wall surface due to its tendency to show imperfections.

Preparing the Walls

When you're gearing up to refresh your space with new wallpaper, good preparation is the key to impeccable results. It's not just about the wallpaper itself: the state of your walls can make or break the final look.

Cleaning the Walls

The first crucial step is ensuring that your walls are clean and free from dust, dirt, or oily residues. Use a mild detergent or sugar soap, paired with warm water, to effectively remove any surface grime. This is essential; wallpaper won't adhere properly to dirty walls. After cleaning, give the walls ample time to dry completely before proceeding.

Repairing Any Damages

Next, inspect the walls for any imperfections. Fill any holes or cracks with wall filler or spackle to create a smooth base. This step can prevent future issues with your wallpaper's adhesion and appearance. Remember, wall damages left unchecked can lead to wallpaper peeling or bubbling prematurely.

Smoothing the Surface

To achieve a professional-grade finish, the wall surface should be as smooth as silk. This may require you to sand down the filled areas and any other rough patches. Ensure you're working with a fine-grit sandpaper to avoid creating more texture on the wall. Once sanded, wipe the walls down again to remove any lingering dust.

  • Sanding: Creates a smooth, even base for the wallpaper.
  • Dust removal: Critical for clean adhesion.

Measuring and Cutting the wallpaper

Calculating the Amount of Wallpaper Needed

Before you begin the wallpapering process, it's crucial to determine how much wallpaper you'll actually need. The last thing you want is to run out mid-project or overspend on surplus rolls. Wallpaper calculators are invaluable tools for estimating the required quantity. They account for the design repeat and wall dimensions to suggest the appropriate number of rolls.

Remember, walls and ceilings are seldom perfect—their unevenness often necessitates extra wallpaper. Make a habit of purchasing at least one additional roll beyond your calculated needs. This ensures that you have enough to cover any mistakes without the stress of reordering. Recall that from dye lot to dye lot, subtle colour variations may exist. Buying in bulk ensures consistent colour across your entire space.

Consideration Why It Matters
Design Repeat Influences the quantity required to align patterns correctly
Wall Size Determines the baseline amount needed
Extra Roll(s) Provides backup for errors and future adjustments

Tips for Accurate Measuring and Cutting

Measuring and cutting with precision are foundational for professional-looking wallpaper application. Start by using a tape measure to gauge the heights of your walls accurately. Add a few centimetres to each measurement for a trimming margin. Use a sharp craft knife or wallpaper scissors to ensure clean cuts; dull blades can lead to tattered edges and wasted paper.

  • Always measure twice, cut once; double-checking your numbers can save you from costly mistakes.
  • When marking your cut lines on the wallpaper, do so on the back to keep the front pristine.
  • For patterned wallpaper, align the design before cutting. This might mean accepting some waste to match the pattern at the seams efficiently.
  • Utilize a straight edge—metal is ideal, but a sturdy ruler can suffice for precise trimming.
  • Keep your cuts steady and consistent. A good technique is to unfold and cut the wallpaper against a flat surface, maintaining control over the paper.

A final piece of advice: If you're new to wallpapering, it's wise to start with a less critical area—a small, inconspicuous space, to hone your skills. This way, you'll gain confidence and reduce the risk of errors in more prominent, unforgiving areas.

Applying the Paste

Preparing the Wallpaper Paste

Before you start hanging your wallpaper, preparing the paste correctly is crucial. Always read the label for the specific paste you're using as different types have different preparation methods. Here's a general guide to get you started:

  • Start by mixing the paste in a clean bucket to achieve a consistent texture without lumps.
  • Use clean, cold water and gradually add the paste powder to the water, stirring constantly.
  • Once mixed, let the paste sit for the time recommended on the packaging, which usually allows the adhesive to fully dissolve and thicken up.

Applying the Paste to the Wallpaper

Proper application of paste to the wallpaper ensures that it will stick smoothly and evenly on the wall. For the best results, follow these steps:

  • With the paste prepared, apply it to the wall if your wallpaper is the paste-the-wall type. Ensure you spread a couple of centimetres beyond the width of the wallpaper to cover the entire section of the wall where the strip will go.
  • If you are using traditional wallpaper that requires pasting, lay it face down on a clean surface and apply an even layer of paste, covering every inch to avoid dry spots that could cause peeling.
  • For precision and clean edges, use a brush for the edges and a roller for the larger areas. Applying paste in excess on the edges ensures they adhere well and don't lift.

Hanging the Wallpaper

Starting at a Reference Point

Before you begin the application process, it's crucial to start at a reference point. This ensures your wallpaper application is precise and that the pattern flows seamlessly across the room. Firstly, identify any focal points in the room, such as a fireplace or main window. These features often dictate the best starting point for your pattern alignment.

  • Accuracy is vital. Use a pencil and spirit level to draw a straight, vertical line, known as a plumb line. If there's no clear focal point, start on the left side of the wall.
  • Add 3 inches for trimming to the measurements of your wall to allow for excess at both the top and bottom edges.

Remember, your initial panel sets the precedent for the rest of the installation, so taking the time to measure and mark your starting point accurately is time well spent.

Aligning and Smoothing the Wallpaper

Once the first strip is in place, alignment and smoothing become your focus.

  • Apply paste evenly using a brush or roller, extending slightly beyond the wallpaper's edge.
  • Carefully hang your first strip, making sure it aligns with your previously drawn plumb line.
  • Remove air bubbles by smoothing the wallpaper from the center outwards using a tool crafted for this specific purpose.

Alignment is key. Each new panel should be placed flush with the previous one, avoiding overlap, to maintain the integrity of the design and surface.

Dealing with Corners and Obstacles

Corners and obstacles, such as light switches or doors, can complicate the wallpapering process, but a systematic approach can streamline the task.

  • For outside corners, measure from the last full strip to the corner and add half an inch to this measurement for the next strip.
  • Apply the strip, smoothing firmly into the corner, and then bend the excess onto the next wall for a sharp edge.
  • Cut precise holes for outlets and switches after the paper is applied, using a craft knife for accuracy.

Trimming and Finishing Touches

Trimming Excess Wallpaper

Once you've hung your wallpaper, precision trimming ensures a polished look. You'll need to trim around windows, doors, and the baseboard. Here's how:

  • Hang the wallpaper, allowing 3 centimetres of excess to overlap frames and baseboards.
  • For top and bottom edges, wait for the paste to dry, making the paper easier to cut.
  • Change your utility knife blades often to avoid tearing the paper with dull blades.
  • Guide your cuts with a straight edge, such as a wide putty knife or a ruler, pressing firmly against the trim or ceiling.
  • A sharp craft knife or breakaway knife is essential for cutting wallpaper for a clean edge.

Blending Seams

Properly blended seams are virtually invisible:

  • Ensure your wallpaper seams align edge-to-edge; overlapping creates ridges.
  • When hanging consecutive strips, slightly overlap the paste onto the edge of the already applied panel.
  • Gently press the edges together using a wallpaper brush or a seam roller.
  • Soft taps with the brush or gentle rolling will help conceal the seam.
  • Move onto the next panel, always checking for a flush seam alignment.

Cleaning Up

Post-application cleanup contributes to the wallpaper's longevity and aesthetic:

  • Remove excess paste with a damp sponge or microfiber cloth.
  • Wash gently to avoid saturating the wallpaper, which might weaken the adhesive.
  • Focus on the edges where paste tends to build up.
  • Ensure electrical outlets and switches are paste-free; this usually requires careful attention.
  • Finally, rinse your tools well and clear the workspace of any debris for a job well done.

Armed with these tips, you're now ready to transform your space with the perfect wallpaper application. Remember, precision in trimming and attention to detail in the finishing touches can elevate your room from homemade to high-end. And don't forget, a thorough cleanup is just as crucial for maintaining the wallpaper's appeal as the application itself. So go ahead, give your walls the makeover they deserve and revel in the satisfaction of a job well done.
