treatment of drywall corner
« on: June 09, 2005, 03:01:44 AM »
How would one go about treating a wall corner that on one side of it has a resilient floated wall but the other wall isn't resilient?  Imagine an "L"  ......the left most vertical side is the resilient wall while the bottom of the "L" is just regular drywall screwed to studs.   How do you tape/seal that corner where the two drywall pieces meet??

Just bring your floating wall up the the solid wall but leave a 1/4" gap.  Caulk the gap shut with a full load of acoustical caulk, tape and paint in the normal way.

See the illustration at http://soundproofing.org/images/wall_2d.jpg for the detail of this and how to join two floating walls.

Be sure to use acoustical caulk- ordinary caulk is not nearly as effective;  see

I'm sorry for not clarifying.  The corner is an outter corner.  I understand that you would tape an inner corner and spackle to seal it.  What about corners that protrude out.  Under normal drywall practices, one would use a piece of metal trim to join the two pieces of drywall that form the corner.  What would you use if one wall is resilient and the other is not?  I'm concerned because the trim must usually be hard nailed.

Ah yes, an OUTSIDE corner!

For that it would be exactly the same as for an inside corner, but of course you need a metal protection for the corner.

Narrow offset corner bead would be the solution: you wouldn't want the metal to cover the acoustical caulk joint, but it's OK to tape and mud over it.

To keep the tape and mud at a minimum, use a primer such as Level 5 which will keep the thin coat from showing through the paint.

Any of you out there doing your own drywall should check out Level 5 as a professional paint job can easily be done with it.
