Hey guys, I’m building a mantel and come to find out I didn’t frame the wall perfectly straight. I am painting the mantel but I need advice on how you guys would fill the gap. I’ve considered caulk but I’m worried it will look bad. I’ve read about how people will use spackle. I attached a picture. Thanks for the advice!!

I had the same issue with a mantel, and I scribed the mantel to the wall for a tight fit. Just run a carpenters pencil against the wall, and mark the line on your project. Then belt sand it to fit.

Wow, that’s a great recommendation. I should have posted here first. So the problem I have is 1. I don’t have a belt sander. That is on my list of tools I need still for sure. 2. The bigger problem.. I already secured the mantel top.. slap my forhead

You might look at running a small piece of moulding across the back. I’d rather do that than caulk it.

+1 Better to creatively hide the mistake rather than try to patch it with less than the desired results.

You can also remove the drywall from the footprint of the mantle as well and it will sink right back in the hole.

The right way to do this is to scribe it to the wall. (Too late to detach, scribe, and re-attach?). second best is to mud the wall and repaint (mask off the mantle first.). Third, Bondo.

id go trim or scribe it. bondo or mud i think wouldnt be wise as wood moves and the two of those would eventually crack.
but then again i have the same problem with my mantel. i dont notice it unless im cleaning the mantel.

Pretty sure some genius of days gone by invented quarter round trim for things just like this….:)

Scribe, remove, fit it properly, reinstall. You know that’s what should be done.

Trim would spoil the look – especially if you’re going for a floating shelf look. It’s already been said and I second, scribing the wall or mudding the hollow. If you mud the hollow, add some plaster of Paris powder to the mix.
