"Whitewash" focuses on their shared house, making it a metaphor for their relationship. The bridge speaks of starting completely new, getting new pictures, redoing the floors, anything for their relationship to feel new and untouched again. At points in the song, it seems like Burruss is slightly hopeful that they'll be able to make it. Her use of "we" in the chorus makes the couple seem united in their goal to make it past their differences and stay together.
But there's something undeniably sad about this song. They're attempting to fix their mistakes and move forward with their relationship, but Burruss's image of 'whitewashing' indicates they're just painting over it and forgetting about it. They're ignoring the problems instead of facing them and dealing with them. The somber tone and melody of the song betray the somewhat hopeful message. That hope that's there won't last for long.
This song is a classic country song in the making. Burruss continues to impress.
