The wife and I have just bought a house and thought we would attempt to build us a mud closet. If that’s what you call it. Haha. We’re pretty inexperienced. So does anyone have any suggestions on how to hide the seams from the 2x4’s? The wife wants to paint it but would like it to look more finished. She suggested using wood filler. I’m worried with people sitting on it, it will start breaking away at some point. Thanks.
