Perfectly rustic beautiful pine. Has some splits on top and bottom but they're narrow.  Some sap still weeping but its curing nicely. We installed concrete board over our drywall so we could tile with ledgers. Easy mounting over the concrete board with ledgers above and below. It's stunning!  The driftwood stain is perfect. The stain is moisture proof and the finish of the wood is rustic. You can see the cleat marks where it was held for cutting and processing in the wood mill. We're very happy with it.
