The half wall that divides our kitchen and family room is one of those things that’s both a blessing and a curse.
I like how it separates the two spaces while keeping the open feel but until we capped it it always looked dirty because the top of it was just drywall with orange peel texture - the same as our walls, and those little bumps collected dust.
Capping the half wall was on our to-do list for a really long time and it wasn’t until we were perusing model homes recently that I noticed a capped half wall that was done in a really modern way.
So naturally I inspected it closely, took some mental notes, and came home to figure out how we could get the same look on our half wall.
And it turned out to be so much easier than I thought it would be! – We should have done this project years ago!
Before we capped our half wall
As I mentioned this half wall always looked dirty because the texture on it was hard to wipe clean. Beyond that, it looked unfinished - forgotten.
We considered capping this pony wall with the same white quartz that we used on our kitchen island and in the kid’s bathroom, but it would have been hundreds of dollars, so capping the half wall with wood was a better financial choice for us.
After we capped our half wall
The wood cap on the half wall gives it a finished look and the painted surface is easy to wipe clean.
How to cap a half wall
Before you begin, sand and paint your MDF board.
I wanted the edges of my half wall cap to be slightly rounded so I took a piece of sand paper and wrapped it around the edges when sanding to give it a nice edge.
You’ll also want to sand the top of the MDF so it’s very smooth.
Tip: The smoother surface you start with the easier it will be to get a smooth finished surface.
Once you’ve sanded, wipe it clean with a damp paper towel to remove any dust.
Apply your paint with a sponge roller letting each coat dry completely.
Lightly sand and wipe clean between each coat of paint.
I applied three coats to give it a nice smooth long lasting surface.
Step 1: Prepare your surface
We had a lot of nicks and dings along the edges of the half wall, so we patched them up with a little drywall spackle and touched up the paint so that when we added our cap these blemishes wouldn’t show.
Step 2: Attach your flat molding pieces
- Cut a 45 degree edge at the end of each molding piece that will lay on a corner.
- Lay your flat molding just slightly off the edge of the top of your half wall.
- Then secure with finishing nails to hold it in place
- If your first piece isn’t long enough, lay another piece along the wall and mark the remaining section.
- Cut the extra piece with a straight cut and attach with finishing nails.
(optional step) Attach molding across your half wall if it is wide
Our half wall is 14 inches wide; in order to make sure the MDF is supported and to have a place to nail into to keep it in place, we attached a few extra pieces of molding across the top of our half wall.
Tip: Mark where each cross piece is placed with a piece of blue painter’s tape so you’ll know where to nail later.
Step 3: Apply wood glue
- Bring your board(s) close to where they’ll be placed.
- Run a line of wood glue along the molding pieces.
Step 4: Place your top piece (painted MDF board)
- Place your board so that it hangs over the half wall evenly on all sides.
- Using finishing nails, nail the board in place along the center pieces. You’ll know where they are from the blue tape marks you made.
Step 5: Patch the nail holes and caulk the seams
- Patch the nail holes and any top seam you may have, sand it smooth, and touch up with a final coat of paint.
- Run a thin line of caulk along all the seams, dip your finger in water and run it along the same line to smooth out the caulk.
- Let the caulk dry completely before doing any touch up to your wall or wood cap paint.
And that’s it!
The way this simple project has made this entire space feel more finished is amazing.
It’s crazy how just adding the white painted wood surface to the top of our half wall has added character and a bit of a custom look to our home.
