I have been looking into this since we bought a camp that the majority of it is a modular home. Since it is a camp I don't think I am going to bother, but if it was my primary home I would. It seems the best way is tape, mud and sand. I would use mesh tape if the home is not on a permanent fountain.

Thanks, that is what I was thinking but I have heard about paintable silicone. Can I use the mesh to do corners?

They make paneling seam tape.

No you can't use mesh for inside corners. I don't really know about caulking the seams. I did use a paintable flexible caulk at camp in a couple ceiling seams that cracked due to expansion and contraction and it is working good. I'm not sure , but I think it would be harder to get a smooth and flat enough unnoticeable seam with caulk. My ceiling is popcorn so i didn't need a perfectly smooth seam.

Good luck. I hate working with mesh tape. For me paper tape is easier to work with, or maybe I am just use to using paper.

I use mesh tape in corners. I've never heard that you shouldn't.

I'm the opposite of functionthenlook. I find mesh to be easier to work with than paper. As he said, it's probably just what you are used to.

I think the pros use paper, so it might be the superior product but maybe just typically harder to use(?)

I use mesh tape too, but, if you are talking about outside corners, I would buy the corner bead, and tape and mud that. I also wonder if this is going to show regardless, because of the texture on that paneling. It wont match the mud you need to put on the seams.

I should of said you shouldn't, not couldn't use mesh tape in a inside corner. It is harder to get a crisp corner with mesh.
