Bare brick wall as backsplash for shower?
I’ve got an interesting question from a client. I’m finishing off the third story of a house. Part of that is finishing this roughed in bathroom that was done, I believe, two owners prior. The end of this space is the shower. This being an exterior wall my plane was to build, insulate, vapor, cement board, tile etc. as usual. But they’ve requested leaving the brick exposed as is.
My first thought was no way. But a bit of research suggests it’s possible. The process seems very simple, too simple is some ways. Thoroughly cleaning, vacuuming, washing with soap, numerous brushings, etc. Then applying multiple layers of waterproofing agent, and/or epoxy.
My question is, has anybody actually done this and have tips, experiences, or comments on long-term viability?
He wants to match the kitchen, pic also included.
Thanks
