Install Drywall End Corner Bead
There are two main ways to bead drywall at the end corner, to give it a clean finished look.
One method is to apply J-bead. First, determine if the edge is to have
a finshed look with the finish of the bead, or if the end corner is to
be drywall finished.
If leaving the vinyl reveal (short side of the 'J' ) is sufficient,
apply the reveal style. This is popular for vinyl window returns, to give
a definite manufactured edge look. If this bead were to lend a
contrast that is unsightly,
a finishing J bead style (without a reveal) may fill the order.The J bead is made is slip over the end of the wallboard, and thus comes in wallboard thicknesses available in 8' and 10' lengths for 1/4", 3/8", 1/2", 5/8" and 3/4" panels.
The other main option is the L-bead. Shaped as it sounds,
the bead is made of metal or vinyl and is formed with a raised edge, to
retain compound. These
beads make a transition from drywall to a dissimilar materials, like concrete,
paneling, or stucco.
When complete it creates a
uniform exposed end.
To install, drive nails or screws
roughly every 6 inches and apply mudd overtop with the raised edge
defining the new corner. If a tearwaway strip exists, pull it free on applying
the compound
- this is a
design
that
ends the corner off clean.The L bead is available in the same dimensions
(with possible exception of 3/4 inch)
