How to install cove molding on curved drywall corners.?
Question:Our drywall (outside) corners are rounded. We tried to put up cove molding but it doesn't look right because of the gap it leaves. Anyone have tips and tricks to do this?
Answers:
A rounded corner is too tight to bend anything around. I would treat it like a normal sharp corner, with a 45+45=90 degree miter for the molding - but add a filler block that takes up the space between the rounded corner and the sharp miter.
Saok wood in water for several hours before attempting the installation.
If it is plastic, try heating it with a hairdryer or a paint removing heat tool
There are several different ways of "bending" wood, but the radius of the curvature is what will be most limiting. If you have the tools (clamps and router), you can glue together thin pieces of wood (laminated) in the curve you want and then use a router to cut a pattern. Local "woodsmiths," if you have any around you, would be able to create curved molding for you. Easiest thing is to use rubber/vinyl cove moulding.
Use a professional - a few will do it, but they are rare. Your best bet is to try a local carpenter. He'll know the woods that bend easiest, and have the technique to make it work.
If you must do it yourself:
Plastic molding - heat it and bend it to suit. Don't overheat, and don't use an open flame, or you'll have a mess. And watch out for toxic fumes - best to do the heating outdoors.
Wooden molding - try steaming the wood and bending it. Hold it in the correct position with wood clamps until it sets (this can take quite a few days.) Remember that it must hold the correct curve before being attached - otherwise, it will pull the nails out. You can also make relief cuts to help it bend, but these will almost always show, unless you're VERY experienced at this sort of thing.
Good luck!
Hi;
Not easy... you could fade the coveat 45 degrees so it fades into the turn of the bead... but that leaves the end undressed. You could camfer the edges with little triangles of cove (if you have a miter saw) but you'll still be left with gaps to phenoseal.
I've never done it, but google images with terms like "rounded", "corner bead", and "moulding".
I found this after about 5 minutes:
