FAQ
I've bought patterned wallpaper but it looks too small in the room – what went wrong?
Often, buyers underestimate the visual impact of a large pattern and don’t account for the overall scale. Measure your wall carefully considering the width and height of the repeat to ensure it’s appropriately sized for the space; smaller patterns work best in smaller rooms.
I paid for features on the wallpaper that I didn't actually use – what can I do?
Carefully review the product description and technical specifications before purchase, paying attention to details like colour variations or special effects. If you’ve been misled, contact Amazon customer service regarding their standard returns policy.
I’m struggling to calculate how much wallpaper I actually need – where can I find a calculator?
Several online wallpaper calculators are available; these typically require you to input your wall measurements and the pattern repeat size to determine the amount of rolls needed for your project.
What extra costs should I factor in beyond just the wallpaper itself?
Remember to budget for adhesive, scissors or a trimming tool, seam roller, plumb bob, potentially specialist tools depending on the type of wallpaper (e.g., vinyl), and potentially underfloor preparation materials like smoothing paste.
My patterned wallpaper is showing through – what am I doing wrong?
Incorrect application is a common cause; ensure you’re using enough adhesive and applying it evenly, paying close attention to the manufacturer's instructions for that specific type of paper.
I've cut a piece of patterned wallpaper incorrectly and now it looks awful – how do I fix this?
Carefully assess the damage and consider whether you have enough unused material; if not, it’s often best to start again, as attempting repairs can be difficult and result in further imperfections.
What kind of tools will I need for installing patterned wallpaper?
You'll generally require a good quality measuring tape, sharp scissors or a trimming tool, seam roller, plumb bob, smoothing brush, and potentially a specialist wallpaper paste application tool depending on the product’s adhesive type.
Should I always buy extra wallpaper when buying a patterned design?
It's advisable to purchase at least 10% – 15% more than you calculate as needed to account for pattern matching errors, trimming, and potential damage during installation.
How do I deal with the pattern matching process for wide-width wallpaper?
Carefully plan your layout considering the repeat; using a plumb bob is essential for accurately aligning the first strip, and ensuring accurate measuring is paramount to avoid visible seams.
What’s the best way to prepare my walls before applying patterned wallpaper?
Ensure your walls are clean, smooth, and dry – lightly sanding any imperfections and using a suitable wall primer will improve adhesion and prevent the paper from lifting or bubbling.
In depth
It’s easy to get swept up in the visual appeal of patterned wallpaper – a bold floral, intricate geometric, or even a traditional damask can dramatically transform a room. However, simply selecting a roll based on aesthetics alone can lead to significant issues down the line. Many UK homeowners make mistakes when purchasing patterned wallpaper that ultimately impact the look and cost of their project. Let’s examine some common pitfalls and discuss how to approach this decorative undertaking with greater foresight.
One of the most frequent errors is failing to accurately assess the space and, consequently, buying too much or too little wallpaper. It's incredibly easy to be seduced by a large roll, assuming it will cover an entire room without considering factors like wall height, window placement, and the complexity of the pattern itself. A busy, intricate design, for example, will require considerably more paper than a simple stripe. Measuring each wall precisely – accounting for any recesses or protrusions – is crucial. Then, carefully calculate how much wallpaper you need to achieve your desired coverage, remembering that patterns will break up the visual flow and therefore increase the amount required. It’s far better to buy slightly more than needed, allowing for mistakes and trimming, rather than running short halfway through a project.
Another common mistake relates to features within the room – particularly windows and doors. Patterned wallpaper can exacerbate the appearance of these elements, making them seem larger or smaller than they actually are. A complex pattern applied vertically will visually elongate a narrow room, while a horizontal pattern might make a low ceiling appear even lower. Carefully consider how the chosen pattern will interact with existing architectural features before committing to a large purchase. If possible, test a small sample of the wallpaper on an inconspicuous area of the wall – perhaps behind furniture – to see how it looks in natural light and alongside your room’s existing décor.
It's also vital to factor in the hidden costs associated with installing patterned wallpaper that are often overlooked. Many homeowners focus solely on the cost of the wallpaper itself, neglecting expenses like specialist adhesives (certain patterns require specific formulations), smoothing tools, seam rollers, taping supplies, and potentially even the cost of hiring a professional installer. Complex patterns demand more time and skill to apply correctly, increasing labour costs if you choose not to undertake the work yourself. Obtain detailed quotes from various suppliers – including those offering installation services – before making your final decision.
Furthermore, be wary of being swayed solely by headline specifications or technical details that seem impressive but aren’t relevant to your needs. Some manufacturers highlight features like "washable" or “paste-the-wall” application without fully explaining the limitations. A “washable” pattern might still require gentle cleaning methods and may not withstand heavy traffic, while a “paste-the-wall” option could be more challenging to apply correctly for a DIY enthusiast. Focus on understanding the wallpaper’s suitability for your particular room – its light levels, intended use, and your own skill level.
Finally, don't underestimate the importance of careful pattern matching. Many patterned wallpapers are designed with vertical or horizontal repeats, meaning that you need to ensure that the pattern aligns consistently across adjoining walls. This requires meticulous measuring and cutting, particularly when working with longer lengths of wallpaper. Consider purchasing extra length for at least one wall to allow for adjustments and to minimise visible seams. Investing a little time in accurate pattern matching will significantly contribute to a professional-looking finish.
Taking these considerations into account – from accurate space measurement and feature assessment, to factoring in hidden costs and understanding the technical specifications of your chosen wallpaper – will dramatically reduce the likelihood of costly mistakes when transforming your home with patterned wallpaper.
