The Ultimate DIY Guide: How To Plan And Install Panelling

It may have taken us way longer than expected (we started the project back in December last year!) but we’ve finally finished panelling our guest bedroom – and we love it!

It adds interest, texture and a luxurious feel to any room and we think it suits the style of our apartment which is, let’s face it, way more grand than we are!

Installing panelling is a really easy DIY project and we learned a lot from the last panelling project in our house in Manchester where we added panelling to the wall along the side of our staircase.

Planning the panelling for the staircase was easy but planning panelled walls for a whole room is a bit more involved. Don’t worry though, it’s still not difficult and we’re sharing the exact steps we took. (Just ignore the semi-stripped doorframe!)

Warning: We go into as much detail as possible to help you if you’re thinking of planning & installing panelling. There are lots of before, progress and most importantly lots of after pictures if you just want to skip straight through to those though!

This is what you will need to plan and install panelling:

Step 1 – Planning

• Tape measure
• Pencil
• Paper
• Ruler

Step 2 – Preparation

• Masking tape – lots of it!
• Laser level
• Ladder (depending on how high your panelling will be)

Step 3 – Installation

• Timber moulding strips
• Nail gun & nails – alternatively No Nails
• Mitre saw – alternatively  fine saw & mitre box
• Sandpaper – about 120 grit

Step 4 – Finishing

• Caulk – lots of it!
• Caulk gun (this is the one we have – don’t opt for a plastic one!)
• Primer & paint to finish the panelling and room

Here are our tips on how to plan and install panelling on your walls:

Step 1 – Planning

This is the most important bit of this project and it’s also the most time-consuming part. It may seem like a lot of faffing to prepare such detailed plans and drawings but once you’ve perfected the planning nothing else can go wrong! It’ll also save lots of time in the long run!

Start by measuring your room.

You want to measure every length, opening, bulge and recess. Also make a note of any fixture and fittings like sockets, light fittings or built-in furniture that can’t (or shouldn’t) be moved.

Draw a plan of your room.

You don’t need any fancy software to do this just the measurement you took, a ruler and pen and paper are perfectly fine.

Once you’ve got your drawing you’re ready to start planning!

Design your panelling options.

Get yourself some sketch paper (any thin paper that you can see though is more than enough – even baking paper will do!) and lay it over your drawing.

Now it’s time to start sketching.

Your drawing doesn’t have to be perfect at this point it’s more about getting an idea of what could work and what your options are. As you can see, I also moved the furniture around in the drawing to line up with the panelling.

Have a look at your room.

Are all walls equal sizes? Do you have any specific features that need to be taken into consideration? Do you already have a look for the panelling in mind?

Start by drawing lines that represent the width of each of your panelling panels. Basically, you’re dividing your walls into sections. Literally, just draw lines along the walls of your room and try to find a pattern that works for you.

Here are some tips to get the pattern to work:

• Can you find a common width? How wide is the door? How wide is the smallest wall – could that be the panel size?
• Adjust the width of the panels.
• Adjust the width of the space between the panels.
• The sections don’t have to be the same size – you could use two or even three different panel widths. We’d recommend using no more than two or three different sizes to keep a coordinated feeling.
• Do you have any art that you want to be able to hang within a panelled section? Make sure the sections are big enough!

Try as many options as possible and even if you think you’ve already found the perfect solution, try and find a few more. You’d be surprised at how many more options you can find! Sometimes the ones you struggle to find are the best ones!

Note: Our drawings are more precise than they have to be for the purpose of showing you the steps. I’m sure no one could have made any sense of my scribbles otherwise!

Start to prepare your detailed floor plan.

When you’ve decided on a design that works for you it’s time to get specific. Draw out the design in detail and to scale on the drawing of your room. When you’ve drawn in all panels it’s time to start thinking three dimensional.

Draw the elevations of your room.

Don’t worry, it sounds way more complicated than it is! Imagine that you’re folding down the walls of your room. You already have your floor plan so all you have to do is project the edges of the room upwards. Don’t forget to mark the positions of your windows and doors, too!

You should end up with something looking like this.

Draw the panelling.

Now that you’ve prepared your floor plan and drawn your elevations it’s time to add the panelling. You’ve already drawn the lines for your panelling on the floor plan so it’s just a matter of projecting the panels up onto the elevation (the same as you did with the walls).

Now you can really start to see how the panelling will look in your room and you can start to think about how you may want to divide the panels further.

Do you want a dado rail or a picture rail? How high will your panels be? What gap is there between the skirting, will you have panels over doors and windows? And most importantly – how does it look? Do you like the scheme so far? Do the panel sizes look in proportion? Would any adjustments make it look better? Don’t forget to take the width of the timber moulding into consideration, too!

Make sure you’re really happy with the design before moving on to the next step. Remember, working out where the panels go is much easier and quicker on paper!

Here are some tips to get the pattern to work:

• Don’t forget to take the positions of sockets and switches into consideration! You don’t want to end up with a socket in the middle of a panel! Don’t assume they are at the same height!
• Take all of the walls of your room into consideration. It’ll feel more harmonious if the panelling on the opposite walls mirrors each other. 
• Planning is the most important step of the whole process. Actually attaching the panelling is really easy as long as you’ve done your prep work.

Step 2 – Preparation

Transfer the measurements of your drawing to the walls.

Having worked out the design for the panelling it’s time to transfer it to your walls. With all of the planning you did in step one, this should be fairly easy.

Work your way around the room with your tape measure and pencil and make a mark where every vertical line/panel piece will be. Then make marks where every horizontal line/panel piece will be.

In our case, we’re installing a dado rail with a small panel beneath it and a larger one above it.

Tape your design onto the walls.

Your walls should now be covered with loads of little dots representing where you’ll be attaching your panels. To make life as easy as possible, we used our new laser level to project the lines onto the wall.

With our lines projected onto the walls, it was then just a matter of working our way around the room with a lot of masking tape and marking where the panels will be.

It was so quick and saved a lot of messing with a spirit level! Best of all you can project a line all the way around the room (both horizontally and vertically) which means that it’s ideal to get the panels on opposite walls to align perfectly with one another.

When it comes to actually attaching the panelling it’ll make life much easier if you don’t have to install it directly on the masking tape so it’s important to decide if you’re taping within the measured lines or outside of the lines. This way you can install the panelling next to the masking tape.

If you’re panelling a large room we’d totally recommend using a laser level like ours but a normal spirit level will work fine, too.

Step 3 – Installation

As weird as it may sound, installing the panelling is the easiest part of this project!

Cut your timber to size.

Double-check your measurements (more than once!) before cutting. It’s advice I give here all of the time but we’ve still made so many mistakes over the years! Measure twice, cut once!

You can cut the panels by hand with a fine saw and mitre box (which is what we did when we fitted the panels along the wall of our staircase) but I would really recommend using a mitre saw.

It may look like a scary tool but I honestly can’t believe we ever did any DIY without it and it’s easily one of our most used tools! Ours is an entry-level version that really wasn’t expensive.

Give any edges that are rough a quick sand with some sandpaper (around 120 grit). The cleaner the cuts and edges are the easier it’ll be to attach the timber to the wall and achieve a professional finish.

If you have to join any pieces of panelling in length don’t just push two ends together. Cut both at a 45° angle so that they slot together. This way the join will be invisible when you’ve painted it.

Tip: We’d recommend buying your panelling at timber merchants and not a DIY store. We found the quality to be better but more importantly, the pieces of timber tend to be much straighter which makes installing them much, much easier!

Attach the panelling!

This is the step you’ve been waiting for.

We used No Nails to attach the panelling along our staircase wall but with so many panels to attach it’s not something I’d recommend for a larger project.

This time we used our nail gun to attach the panels (which is still our favourite tool ever!). Nail guns are really expensive and although we love ours we wouldn’t recommend buying one for just one project (although you’d be surprised how often you end up using it).

Luckily you can easily hire nail guns if you don’t want to splurge on one of your own.

Attaching the panelling to the wall is the easiest and quickest part of this project. Hold the panel in position (depending on how you’ve planned either inside or outside of the masking tape edge) and nail it to the wall.

If you’re installing a dado rail, we’d recommend starting with it. It’ll be your main horizontal line and you can use it as a guide to making sure that every other panel you nail is parallel to it.

Because you taped the panelling pattern to the wall with masking tape you don’t need to do any measuring or even check if it’s level as you already did that in the previous step!

Ideally, you’ll have someone to help with this step as it’s so much easier if you have someone to hold the piece of panel while you nail it to the wall. Just remember to take the position of any cables or pipes into consideration before you start to nail into the walls!

We used No-Nails a couple of times where we thought there might be a cable (and still managed to nail into one – whoops!).

When you’ve finished attaching all panels remove the masking tape and you’re done!

Step 4 – Finishing

This step is a bit time-consuming but it’s vital to achieve a flawless and professional finish. You have to caulk every edge and join.

Caulk is your friend!

It’ll hide any imperfections, it’ll join the panels to the wall and it’ll make everything look tidy and clean!

To apply the caulk hold the caulk gun at an angle to the edge and squeeze a thin strip of caulk into the gap. Then dip your finger into some water and smooth the caulk pushing it into the edge.

You can sand caulk when it’s dry but it’s a complete pain. It’s also much quicker to take your time getting the caulk right while it’s still wet.

All that’s left to do is stand back and admire your new panelling!

We recommend waiting at least 24 hours for the caulk to dry before starting to paint the room.

Planning and installing panelling may seem super involved but actually, it’s not complicated or difficult at all. Really it’s just 4 steps (that we’ve gone into a lot of detail explaining) and most of the prep work can be done from the comfort of your sofa! Just take your time and make sure to plan and tape everything as precisely as possible.

I love how our new panelling turned out! It’s really given the room such an elegant feel.

Tips on how to plan and install panelling:

Do

• If you have to join two pieces of timber to create a longer piece of panelling, cut both ends at an angle to join them. It’s a more secure connection and the join will be much less visible.
• Get your calculations right. We calculated the amount of panelling we needed 4 times and we still managed to miscalculate because we missed an entire wall. Both of us. Twice.
• When cutting multiple pieces that are the same size, cut yourself a template piece that you can use to check the size of all other pieces you cut. Making sure that all pieces are exactly the same size will make installing the panelling much easier!
• Use a nailer and mitre saw. If you’re only panelling a small area a fine saw and mitre box and some glue will work but I wouldn’t recommend it if you’re panelling a larger area or if your walls aren’t 100% straight.
• Use a laser level. It is, of course, possible with a normal spirit level but it might drive you mad and the project would take a lot longer to complete.

Don’t

• Don’t forget to take the position of sockets and switches into consideration! You don’t want to end up with something like this! 
• Don’t forget to find out where cables and pipes are located. Although we were really careful we nailed into a cable! Needless, to say it wasn’t our finest DIY moment. Use glue if you’re even remotely unsure of the position of cables.
• Caulk is what makes the panelling perfect! Don’t even be tempted to skip this step! When applying caulk, wet your finger. It’ll make smoothing it much easier and cleaner.
• Don’t ignore your furniture and artwork. Think about where you’ll be placing your furniture and where you want your art to be displayed while planning the layout of the panelling.

Here are a couple of panelling questions we get asked again and again...

As you can see, the room is so close to being finished! We still need to add curtains, I’d like a rug under the bed and there are the all-important finishing touches to add but we’re almost there now!
