When we decided on a wood-planked ceiling for our sunroom, I pictured a quick trip to the big box store, grabbing beadboard, and installing it in an afternoon. Reality turned out to be more complicated: there are many ways to get the beadboard look.
Traditional beadboard is made from individual tongue-and-groove planks—similar to hardwood flooring but with a small ridge, or “bead,” between boards. There are also full-sheet panel options that mimic that pattern. We initially considered 4ft x 8ft beadboard panels because they were very affordable, often costing less than a dollar per square foot. The downside was handling and appearance: lifting giant sheets onto our high, sloped ceiling felt daunting and would have required renting a truck and possibly a drywall lift. More importantly, the sheet panels create visible seams where one sheet meets another. Although trim can hide those seams, we felt the seams would be too noticeable on our angled ceiling and didn’t fit the look we wanted.
Another choice was vinyl planks. Vinyl is appealing for outdoor-exposed spaces because it resists rot and warping from moisture. Some people felt vinyl looked too “plastic-y,” but the deciding factor for us was price: at about $1.79 per square foot, vinyl would have nearly doubled the cost compared to panels.
Ultimately we settled on individual tongue-and-groove wood planks. Both Lowe’s and Home Depot carried similar 6″ tongue-and-groove options; the Lowe’s packs were under $1 per square foot, which fit our budget better. We liked the authentic plank look, the absence of sheet seams, and the real wood grain. We bought 20 six-packs of 6″ planks for a total of $297, about $0.94 per square foot—slightly more than our original target but worth it for a durable, long-term result.
Buying individual planks meant we could transport them in our car and avoid renting heavy equipment, but there were trade-offs. Installation is more tedious because each 6″ board must be installed row by row—about 40 rows in total. Wood can also warp or rot without proper sealing, so we decided to prime and paint both faces of every board before installation to protect them from moisture, even though the backs won’t be visible.
My first painting setup using a plastic drop cloth didn’t work well because the sheets stuck to the boards. The solution was simple: drop cloths on the ground and nylon rope tied between two trees to hang boards while spraying. That let me prime or paint 10–12 planks at a time by spraying the back, flipping, and spraying the front. The whole priming and painting process took several sessions—about four days of two-hour work periods—since we had 120 boards to prime and paint front and back. We could only dry about 45 boards in the garage at once, so I worked in batches: prime, paint, install; prime, paint, install. The sprayer cleanings added extra time, but the effort would pay off when the ceiling was finished.
We used Kilz Premium primer and Benjamin Moore Regal Select Exterior in a low-luster finish for the topcoat. The color, called “In Your Eyes,” is a soft, pure light blue. We wanted a subtle blue that wouldn’t cast a strong reflection into the living room or clash with the brick exterior. Choosing a paint that reads as blue in different lighting was important to us, so we consulted the paint desk and tested samples before committing.
Before installing the planks we addressed insulation. After feedback from readers and some research, we initially re-used leftover insulation from the previous ceiling to help keep the sunroom cooler in summer. The sun beats down on the roof all day, so it made sense to try to limit heat transfer. We used the old insulation and added one new roll to fill gaps.
However, we later learned that installing insulation directly against the roof with no airflow between it and the beadboard was a mistake. Insulation needs ventilation to dissipate heat and moisture; trapped heat and moisture can damage the beadboard and shorten roof life. After consulting a framing expert, we removed that insulation. Catching that error early was a relief and saved us from having to tear out a finished ceiling later. We decided to rely on cross breezes and two planned ceiling fans for comfort instead of insulation in that space.
Installing the planks felt a lot like laying hardwood floors. Setting the first row square to the wall was crucial, so I cut scrap wood spacers to keep the start straight. We ran the planks parallel to the long wall so we could nail into joists spaced every 16 inches, which offers strong support and helps prevent sagging. The long wall required about 2.5 boards per row.
We staggered end joints between rows for strength and aesthetics, so seams never lined up down the ceiling. We cut ends with scarf joints—matching 45° angles—so each seam overlapped slightly for a more seamless appearance and better long-term stability. Wherever seams occurred, we made sure they coincided with a ceiling joist so nails could secure both ends into solid framing.
Sherry handled much of the cutting while I nailed the boards in place. The tongue-and-groove fit made the boards slide together smoothly, though a rubber mallet helped where needed. We used wood glue along joists before placing boards and finished each board with a shot from the nail gun for a secure hold.
It took about five hours to hang our first batch of 45 boards across several days, so progress felt slow. The lighter pace allowed us to discover and correct the insulation mistake before it became a bigger problem. Once we removed the insulation and adjusted our approach, the second round of installation moved much faster. I found a rhythm and completed the next batch in about four hours, though working around two ceiling fan junction boxes required some careful jigsaw work.
By the time the majority of the boards were in place, it finally started to look like a finished ceiling. The last stretch included a narrow area near the peak that was physically demanding—working overhead for days left my neck and shoulders sore—but it also included adding a row of vents along the top to encourage airflow, as recommended by the framing expert.
All the boards are installed now. Technically the planks don’t have a carved bead detail—they rely on the tongue-and-groove joints to create the beadboard appearance—but the 6″ plank size feels right for the space. A smaller bead might have looked too busy at this scale.
We’re in the home stretch. Remaining tasks include adding trim around the ceiling, caulking and painting the trim, filling many nail holes in the boards, and applying a final protective coat across the entire ceiling to seal the seams and keep moisture out. Once those are done we’ll hang two ceiling fans and finish the interior paint and floor tiling.
Progress feels rewarding. It’s almost like I’ve got feeling back in my arms.
Current to-do list:
- Prime, paint, and install beadboard-style planks (completed)
- Add trim around the ceiling, caulk and paint, and hang two ceiling fans
- Repaint sunroom columns and interior trim with white exterior paint
- Tile the floors with outdoor-safe, slip-resistant tile
- Furnish the space with a rug, seating, and possibly outdoor curtains and lighting
- Plan and build an outdoor fireplace down the line
We’re probably more than halfway done, but flooring will mark a big milestone toward the finish line. Between priming and painting these planks and other recent projects around the house, it’s been a busy stretch of painting and progress. We’ll share the trim and fan installation updates soon.
