How to add a DIY library paneling molding look to your walls.
Install your own wall molding (and save a ton!) that gives you that classic
library/dark academia look.
Last I left you on my office makeover, I had installed the peel and stick
wallpaper, removed and installed the new baseboards, installed the chair rail
and given everything a couple coats of paint:
You can read all about that
process and the grasscloth wallpaper I used here.
After that, I stalled out on the DIY stuff (because:
marching band season) till recently. My goal for the lower third of the
wall was to create a library paneling type of look.
There are so many ways to
add character to your walls with molding. For this room, I wanted it to be a simple but beefy look that adds some
detail to this room.
Step One: Deciding on your design
I ended up doing a classic look using two pieces of molding. Simple, primed
one by twos and this cove trim:

When those curved pieces are placed on each side, it really makes that thin
1x2 feel much more substantial:
The curved molding is actually a
paintable vinyl product
that is great for outside and in bathrooms. I like that it's lightweight,
easy to cut and cheaper than wood.
I had already added the curved trim to the top of the chair rail. Usually I
would go with a simple 1x2, but I really like how this turned out with that
coved look on top and bottom of each piece of trim.
Before I got started, I needed to fix some gaping in the baseboards and
chair rail. It was only bad along the long wall in the room:
This is totally normal and sometimes unavoidable -- it's rare that a wall
is completely straight. This one was particularly bad, so before I
added more trim to this wall, I needed to fix those spots.
To do so, you'll want to find the studs along the wall, and then use
a countersinking screw
to tighten it up:
If you hit the stud, your trim should tighten up against the wall
nicely. These screws are great because you don't have to pre-drill into
the wood -- they are very skinny but strong!
I normally don't use screws to attach trim...but in this instance it's
needed. Brad nails won't pull it tight enough.
You want all of the trim as uniform as possible, because as you add more trim to your project, you'll have spots where some of it will stick out or not be flush against each other.
Next up, I needed to figure out the spacing for my paneled molding. To
do this, I take the measurement of the full length of the wall, then
figure out how many "boxes" I want.
I made some simple graphics to give you a visual. I started out with
four boxes, but ended up liking the look of five panels:
I always lean toward odd numbers, it's just more visually appealing to
me. You can do whatever you prefer!
Adding too many will feel busy, and too few will feel unfinished. Find a
good in between!
When I knew how many boxes I wanted, I took the measurement of the wall
and subtracted the width of all of the trim I was using. So for five
panels, I subtracted the width of six molding pieces -- the two sides
and then four in between.
When you have that number, divide it by the number of boxes you want to figure out how wide each panel will be.
I hope that makes sense! I always get a lot of questions about figuring
out the spacing.
Note: I start at each side of the wall, then flip back and forth from
side to side as I work. That way if I mess up my measurements at all,
only the middle panel is slightly off and it looks intentional.
Step Two: Install your molding
To create my "paneled" look. I first took the 1x2 cut to the height I
needed, and marked where I wanted to install it on the wall:
Make sure it's level before nailing in.
This
battery-operated nail gun
is one of my best purchases ever. Before this, I had to haul out the air
compressor and hose, and that thing is LOUD! The cordless version is
heavier, but overall much easier to use.
The brad nails should be sufficient to attach your trim, but if you're
having trouble and/or can't use a stud, try angling your nail gun back
and forth to give it some more grip:
I NEVER use glue to attach my molding! It's rarely needed and if you ever decide to take it down, you'll end up with a ton of drywall damage.
Next up, I installed the coved molding around the edges of each "square"
I created. This is going to create that paneled look.
Thankfully this vinyl product is SUPER easy to cut with my
handheld miter shears so I don't have to run back and forth to the miter saw a million
times:
Be sure to hold your trim tight against the adjustable base so you get a
clean cut.
I nailed this decorative trim all the way around, so it beefed up the
look of all of the vertical trim, plus the chair rail and
baseboards.
Step Three: The finishing touches
The busy work really starts after all of the trim is installed.
It's time to fill all the holes:
When your wood filler is dry, you'll want to give it a super light
sanding and then wipe away any dust.
These little detail sanders are awesome and come with seven
different sandpaper grits:
They are so easy to hold (and if you hate touching the texture of
sandpaper, you'll love these).
After the sanding was done, I filled any gaps with caulk. I always try
to use a dark caulk with dark paint:
It's a bit easier to cover when painting.
Caulk and nail filler will take a project from looking messy to more
professional and complete!
I gave everything a couple more coats of paint and then his paneled wall
was complete!:
These
paintable outlet covers
are a must have if you're painting your walls a saturated color. They
screw right on, no need to rewire the outlet!
I also covered the light switch cover with some scrap wallpaper:

I LOVE this dark green paint color with the neutral grasscloth
wallpaper. It's so warm and moody...very much the dark academia look
that's popular right now (that I've loved for years):

One wall down! 😂 Thankfully this is the majority, since the rest is
mostly windows and a large doorway.
I really want to get this room finished up before the holidays. It's
pretty much done except for finishing up the trim:
I've done so many molding DIY projects over the years, but none quite
like this!
If you have super textured walls, you'll probably want to cover the area
with a thin luan before starting the trim portion of this project.
