Understanding the challenges of wallpapering camper van interiors (and how to deal with them)

Wallpapering your camper van is a bit like embarking on yet another adventure on the road. And just as when you’re exploring different foreign countries, you know there will be challenges, as its various different surfaces will each demand a tailored approach. Exactly in the same way you get ready for a new adventure, preparation is key: you need to plan ahead, make sure you understand what you are getting into, have the right tools at hand and, most of all, a plan of action. To help you with these tasks, we have put together a list of answers to the most pressing problems you are likely to face.

What are the most common materials found in RV interiors?

Think of the interior surfaces of your camper van: be it fibreglass, wood, metal, or a variety of synthetic materials, all of them have their own characteristics and quirks.

Wood: the classic charmer

Whether in the form of plywood, particleboard, or solid timber, wood is a common material in both camper van and mobile home interiors, particularly in cabinetry, flooring, and wall panelling. The natural texture and warmth of wood make it a favourite option, but it presents its own specific challenges when wallpapering:

• Moisture content
  Wood expands and contracts with changes in humidity, which can wreak havoc on wallpaper. Make sure your wood is properly sealed and acclimatised to the environment.
• Surface smoothness
  Depending on the age and state of your mobile home, a wooden surface might present some bumps and imperfections. For a seamless wallpaper finish, it needs to be smooth and free of splinters or rough patches. Filling uneven areas with wood filler followed by sanding down is the best way to provide the ideal substrate for decorating.
• Priming
  A coat of primer is always a good idea when wallpapering on wood, but is particularly recommended if your wood panelling has a glossy finish. Pick a latex primer and let it dry for at least 24 hours.
• Wallpapering paste
  Traditional wallpaper adhesive works well with wood. However, considering that the restricted space within a camper van leads to much more friction than in a normal home, a strong vinyl adhesive might offer better durability.

Fibreglass: a slippery customer

Fibreglass is a popular choice in camper van construction due to its lightweight nature and high strength-to-weight ratio. It is often used in wall panels, roofs, and some structural elements. However, its slick surface poses a particular challenge in terms of wallpaper adhesion.

• Surface preparation
  Fibreglass is smooth - almost too smooth. Its glossy finish generally requires thorough sanding to create a textured surface that wallpaper adhesives can hold on to. Using medium-coarse sandpaper can prep the surface without causing damage.
• Priming
  Due to the smooth, non-stick surface of fibreglass, applying a primer specifically designed for it is generally a good idea. This step ensures that the adhesive will bond properly, preventing peeling and bubbling. Think of it as a firm handshake between the fibreglass and the wallpaper adhesive, ensuring they “stick together” for the long haul.
  Wallpapering paste
  Standard wallpaper paste just won’t cut it for fibreglass. Opt instead for a heavy-duty adhesive designed for non-porous surfaces or use dispersion glue.

Metal: tricky to handle

Metal surfaces in camper vans, often found in structural frames, appliances, and occasionally in decorative elements, create a robust and modern aesthetic. However, its non-porous nature makes wallpaper application as tricky as giving a bath to a cat.

• Surface preparation
  When dealing with metal, the first thing you need to do is to clean the surface thoroughly to remove any grease, dirt, or oxidation. A degreasing agent followed by a spot of light sanding can also help create a suitable surface for adhesion.
• Priming
  A metal primer will help prevent rust and provides a good base for the adhesive. This step is especially important in high-moisture areas like kitchens or bathrooms within the camper.
• Wallpapering paste
  Similar to fibreglass, metal surfaces require a high-performance adhesive. Since many primers tend to not work very well with non-porous surfaces, you should consider using a dispersion adhesive. This ready-to-use synthetic glue works on paper-based as well as non-woven wallpaper types. Just don’t forget that, since it is much stronger than normal paste, removing the wallpaper in the future might be tricky.

Synthetic materials: modern mavericks

Synthetic materials such as vinyl, PVC, and composites are increasingly common in modern camper interiors due to their durability, ease of maintenance, and versatility. These materials, however, can be a double-edged sword when it comes to wallpapering.

• Surface preparation
  Synthetics often come with a protective coating that must be removed or scored to allow the adhesive to bond effectively. A fine sandpaper or deglosser can be used to prepare the surface.
• Priming
  While some synthetic materials may not require a primer, using one tailored for these specific surfaces can ensure better adhesion and longevity of the wallpaper. Test a small area first to determine the best approach.
• Wallpapering paste
  Since we are dealing with non-porous surfaces like metal, it’s a good idea to use dispersion adhesive or an alternative formulated especially for synthetic surfaces. These are designed to work with the specific chemical properties of synthetic materials, ensuring a robust and lasting bond.

What are the best techniques for cutting and aligning wallpaper on curved walls and tight corners?

The compact and often irregularly shaped confines of a camper van present unique challenges that require a deft hand and a meticulous approach when wallpapering. Curved walls and tight corners, in particular, will test your patience and skill. Follow the following techniques for cutting and aligning wallpaper in these tricky areas to ensure a seamless and professional finish.

Wallpapering curved surfaces: mastering the bend

In order to successfully tackle the interior walls of your RV, your measurements need to be extremely accurate. Measure the height and width of the curved section, allowing extra length for any pattern repeats. It’s a good idea to cut the wallpaper slightly longer than needed to accommodate any discrepancies. To avoid wrinkles and bubbles, one trick is to make small, evenly spaced slits along the edges of the wallpaper where it will meet the curve. These slits allow the paper to flex and adapt to the wall’s contours without creasing. Always use a high-performance adhesive to ensure the wallpaper sticks firmly to the curved surface. Apply the adhesive generously, particularly along the edges where slits have been made.
Use a flexible smoothing tool or a soft brush and work from the centre outwards, gently pressing the wallpaper into place, ensuring each slit aligns smoothly without overlaps.

Wallpapering tight corners: navigating nooks and crannies

In camper vans, tight corners are literally everywhere. Whether they are internal or external corners, they present another layer of complexity. First of all, ensure the corner is clean and free from any debris.

• Internal corners
  Check for any unevenness and smooth it out with filler and sandpaper. The overlapping technique works best: Allow the first piece of wallpaper to overlap onto the adjacent wall by 3 - 4 centimetres (1 - 2 inches), thus ensuring there won’t be any gaps or lifting edges. The second piece of wallpaper should be carefully aligned to the corner, overlapping the first piece slightly. Use a straight edge and a sharp utility knife to trim the overlap neatly, creating a tight seam.
• External corners
  Cut the wallpaper to extend just past the corner by about one centimetre (half an inch) and smooth it down firmly. The next piece should wrap around the corner and slightly overlap the first piece. Use a sharp knife to trim the excess, ensuring a clean edge.

Pattern matching: maintaining continuity

One of the trickiest aspects of wallpapering the curved walls and tight corners of a camper van is maintaining pattern continuity. Before cutting, lay out the wallpaper to plan where patterns will have to align. Mark these points lightly with a pencil to guide your alignment. Use a metal ruler and a sharp knife to cut the wallpaper. Ensure cuts are straight and edges are clean, particularly where patterns need to match. When applying the wallpaper, start from the top and work down, aligning the pattern carefully. Adjust as you go to ensure the design flows smoothly around curves and corners. Use a seam roller to press seams down and ensure pattern continuity. Roll firmly but gently to avoid moving the wallpaper.

How do I overcome the challenges of wallpapering in the tight quarters of a camper van?

The secret to wallpapering your camper van is the same as living in it: You need to learn to thrive in its confined space rather than fight the situation. Sure, negotiating the more awkward areas can sometimes be a challenge and the limited room for movement demands a degree of precision and adaptability. However, with the right techniques and tools, it’s not too hard to achieve a professional finish.

Laying the groundwork

Let me repeat it again: the foundation of a successful project lies in thorough preparation and a detailed plan. Start by measuring each surface with a flexible tape to accommodate the irregular shapes and curves of your RV. Record these measurements carefully and double-check them to ensure accuracy.

Choosing the right tools

Standard wallpapering tools can be too cumbersome in the confined spaces of a camper van or RV. That doesn’t mean that you won’t need them, but it’s wise to also equip yourself with a compact smoothing tool, a utility knife, and a small seam roller. They will allow you to navigate tight corners and tiny spaces with ease. Also look for a wallpapering brush with angled bristles to help you apply adhesive evenly in hard-to-reach areas.

Strategic planning and execution

Working in a tight space means you must think several steps ahead to ensure smooth application. Start wallpapering from the most accessible area and gradually work your way into the more constrained parts. This approach allows for easier adjustments and ensures that the wallpaper adheres properly without creases or air bubbles.

Cutting and trimming with precision

In the tight confines of camper van, everything gets magnified. While a small imperfection might go unnoticed in a large living room, you can be sure it will stare straight at you in your RV. Cut your wallpaper precisely according to your measurements as this will reduce the need for adjustments after application. Also, always smooth out the wallpaper from the centre to the edges to prevent air bubbles and ensure a snug fit against the wall. Make sure you have the sharpest possible utility knife and a straight edge to cut your wallpaper strips and label each piece to avoid confusion during installation. When trimming excess wallpaper, do so VERY carefully to avoid damaging the adjacent surfaces.

How do I deal with humidity and temperature fluctuations when wallpapering a van?

Far more than your average home, camper vans and RVs are subject to varying levels of humidity and temperature. Whether parked in a humid coastal area or travelling through a cold mountainous region, internal conditions can change rapidly, from the very cold to the extremely hot. This can compromise the integrity of your wallpaper installation as temperature fluctuations lead to the wallpaper material expanding and contracting, resulting in peeling and bubbling. Furthermore, humidity can weaken the adhesive bonding strength and cause the wallpaper to absorb moisture, making it susceptible to mould and mildew.

Selecting the right materials

Not all wallpapers and adhesives are the same, and choosing those specifically designed to withstand these conditions is crucial. Go for non-woven wallpaper models which do not contract and expand, or vinyl ones as they are inherently moisture-resistant and durable, maintaining their structural integrity even in high-humidity environments. In terms of adhesive, consider heavy-duty, mould-resistant products formulated for use in bathrooms or kitchens as they are designed to endure similar environmental stressors.

Choose the right season to wallpaper your camper van

Unless your RV vehicle is stored in a large, air-conditioned environment, choosing the right time of year to wallpaper your mobile home can make a big difference. The best time to wallpaper it is during spring or autumn, when temperatures are moderate and humidity levels are relatively stable. Avoid the peak of summer or winter, as extreme temperatures can cause the wallpaper and adhesive to expand or contract excessively, leading to poor adhesion and potential damage. Leave the wallpaper rolls in the RV for at least a day or two before starting the project - let them adjust to the environment and “acclimatise”.

Create stable conditions before starting your project

Before applying your wallpaper, ensure that the walls are dry, clean, and primed for adhesion. Consider using a moisture barrier primer to seal the walls. This will prevent moisture from penetrating the surface and compromising the adhesive bond.

Add an extra layer of security by sealing the wallpaper

To further protect against moisture and temperature variations, it’s not a bad idea to apply a clear, waterproof sealant over a non-woven wallpaper. It will act as a barrier, protecting the wallpaper from direct moisture exposure.

How do vibrations and the structural flexibility of my RV affect the wallpaper?

When you wallpaper a camper van or mobile home, everything looks fine until you get moving. By definition, camper vans and RVs are often on the go, which means they flex, vibrate, and shift in ways that stationary homes don’t. This constant motion can create issues for your wallpaper if you don’t take precautions.

Avoid heavy wallpaper models

It’s a law of nature: The heavier the wallpaper, the higher the chance it will detach when subjected to constant vibrations. Take this into account when choosing a model for your RV. Always check for the “grammage” level in the wallpaper description.

Use the right adhesive (and be generous!)

Pay extra attention to the type and quality of wallpapering paste when decorating your camper van. Choose adhesives that are designed to remain flexible even when subjected to constant movement. Apply more glue than you would do for a normal wall at home.

Add extra adhesion points

Use additional adhesion points at critical stress areas, such as corners and edges. You can apply small dabs of heavy-duty adhesive in these areas to prevent lifting and ensure a more secure bond.
