This was the before.
We used cheap pine boards to create the board and batten. A few 1x6s some 1x3s and the edges are 1x4s. My super helpful brother in law who does construction for a living nailed this wall up in like 30 minutes! It's REALLY important to buy straight boards. We just nailed the pine right to the wall with a nail gun. The little shelf on top is a 1x6 with some little triangle supports cut out of the 1x6 scraps.
Then I caulked and wood filled all the holes. After taping everything off I primed with Zinnser cover stain primer followed by two coats of Valspar Enamel paint in high gloss. All applied with a paint brush and foam roller. We used a high gloss paint so the wall will be really durable and washable since my brother has 5 kids.
After attaching some double hooks the wall was finished! Love the detail it adds to the space. Plus the kids now have a place to hang their coats.
The wall cost about $60 in paint and wood. Their entryway looks so much more cheerful and welcoming!
