When we decided to do a wood-planked ceiling in our sunroom, I imagined a quick trip to the home center, grabbing some beadboard, and calling it done. It turned out to be more complicated: there are many ways to get the beadboard look, and each option has pros and cons.
Traditional beadboard is made from individual tongue-and-groove planks, similar to a hardwood floor, with the characteristic little ridge or “bead” between boards. There are also full-panel options—4 ft × 8 ft sheets stamped with a beadboard pattern—which are often the cheapest choice. Those panels were tempting because they can run under a dollar per square foot, but we passed on them. They would have required renting a truck and a drywall lift to get them home and into place, and they create visible seams where sheets meet. On our sloped ceiling we wanted a seamless, authentic look.
We also looked at vinyl plank options. Vinyl resists moisture and won’t rot, which is attractive for a semi-outdoor space, but it felt plasticky in some samples and cost nearly twice as much as the panel option. Ultimately we wanted a real plank look without fake seams, so we narrowed our choice to individual tongue-and-groove wood planks.
We found 6″ tongue-and-groove planks at a local store for under $1 per square foot. The final cost for our order—20 six-packs—was $297 (about $0.94 per square foot). It was a little more than we hoped to spend, but the traditional look and real wood grain were worth it to us for a long-lasting result.
Unlike large panels, these packs fit in our car and didn’t require renting equipment, but they did mean more tedious installation: each board is only 6″ wide, so we had about 40 rows to fit piece-by-piece. Wood also needs protection against moisture, so we committed to priming and painting both sides of every plank before installation to seal them well—even the backs that won’t be visible.
My first painting setup didn’t work: the plastic drop cloth stuck to the backs of the boards. I switched to hanging groups of planks on nylon rope strung between trees with drop cloths beneath. That let me spray the backside of a few at once, flip them, and spray the front. We used a paint sprayer and worked in batches so the painted boards could dry indoors without getting dirty. This prep took several two-hour sessions over a few days—120 boards total, front and back, primer and paint—so it was a slow process but necessary for durability.
We used Kilz Premium primer and an exterior acrylic paint in a low-luster finish from a well-known brand. The color we chose is a soft, pure light blue called “In Your Eyes.” We wanted a hue that reads blue rather than gray or green, that wouldn’t be too bold to reflect heavily into the living room, and that would coordinate with the brick exterior.
Before installing the planks we debated adding insulation between the roof and the new ceiling. Several commenters and our own instincts suggested insulation could reduce heat transfer, since the sun hits the roof all day. We initially used leftover insulation from the old ceiling, but later learned that installing insulation directly between the roof and a beadboard ceiling—without airflow—can trap heat and moisture. That can shorten roof lifespan and cause moisture issues against the new ceiling. We removed that insulation once a framing expert confirmed the problem, and instead plan to rely on cross-breezes and ceiling fans to keep the space comfortable.
Installation felt a lot like hardwood flooring. To keep the ceiling straight we set the first row carefully using scrap wood spacers against the front wall. We ran the planks parallel with the long wall so the boards could be fastened directly to ceiling joists every 16 inches. That gave a strong attachment and should prevent sagging or warping over time.
We staggered the seams from row to row—so the joints would not line up—and cut board ends with matching 45° scarf joints to create tighter, less visible seams. We always aligned seams over joists so the ends could be nailed into solid framing.
One person cut while the other nailed. The tongue-and-groove design helped the boards seat easily, and a rubber mallet encouraged tight engagement where needed. We applied wood glue along joists and used a nail gun to secure each board. The first batch of 45 boards took about five hours spread over a few days, and later batches went faster as we found our rhythm.
As more boards went up the space started to feel like a real ceiling. Near the end I worked around two new fan fixture boxes and added a row of vents across the top to promote airflow, following the framing expert’s recommendation. When all the boards were installed the room finally felt complete—though not technically “beadboard” since these planks don’t have an engraved bead, they lock together to achieve that look. The simpler 6″ plank seemed right for the scale of our room; a smaller bead detail might have appeared too busy.
We still have a few finish tasks left: install trim around the ceiling, caulk and paint that trim, fill nail holes in the boards, and apply a final coat over the entire ceiling to seal seams and protect against moisture. After that we’ll repaint the columns and interior trim in white exterior paint, tile the floor with an outdoor-safe, slip-resistant option, and furnish the room with a rug, seating, and lighting. Eventually we’d like to add two ceiling fans and maybe an outdoor fireplace down the line.
Progress feels great. Even the aches in my arms are worth it: the room is shaping up exactly how we hoped.
To recap our remaining to-dos:
Rip up the old carpetingRemove the sliding doors and tracks to open things upConvert outlets to outdoor-safe, weatherproof outletsAdd new casing to openings and caulk thoroughly for waterproofingDemo the old ceiling and explore the possibility of lofting itRemove old beams, reinforce ceiling framing, and re-route electrical for two fansPrime, paint, and install the wood-plank ceiling- Add trim around the ceiling, caulk and paint it, and hang two ceiling fans
- Repaint columns and the interior of the sunroom with white exterior paint
- Tile the floors with an outdoor-safe, less slippery option
- Bring in a rug, furniture, and consider outdoor curtains and wall lanterns or sconces
- Long-term: build an outdoor fireplace
If you’re planning a similar project, the main takeaways from our experience are: pick the material that balances cost and appearance for your space, fully prime and seal every plank, install with seams over joists and stagger joints, and be cautious with insulation when there’s no ventilation between roof and ceiling.
