Hi,
It would be easier for me to send you a detail
Than to explain this in words. So, if you could
Email me directly I would be happy to send the
Info.
The L metal is used at outside corners of
Sheetrock walls and the taping, mudding,
Sanding leave only the very smallest amount
Of metal at the corner. But this is easiest when
There is a significant return - and unless your
Wall is really thick there is not much of one.
So I use a piece of hidden wood trim that
Runs in plane with the Sheetrock wall
Is slightly shaped to allow the tape to ride
Over it and the wood forms the outside corner
Instead of metal. Paint adheres better to wood
Than to metal.
These are vulnerable corners and I usually
Suggest using a really narrow trim and painting
It the color of the wall. It holds up better over
Time. The applied trim is also less expensive
Than my trim less detail.
If you'd like to see the detail, send me an email.
Thanks for the question.
Cathy
