aligned causing the legs to splay out as shown in . Use your utility knife to bevel off the overlapping drywall for a flush installation as Figure B

Step 3: Always install Rigid Corner Bead with a ½" gap from the floor to prevent structural settling from cracking the mud/compound.
Step 5: Staple the mud legs every 6" with ½" divergent staples. Reapply pressure to the mud legs as needed to guarantee a proper bond. On
arched beads you may need to staple every tab. Securely attaching the bead minimizes the chance of edge cracking. DO NOT install the bead
with nails or drywall screws.
To boost the performance and strength of any drywall compound, use Trim-Tex's high performance MUD-MAX drywall compound additive.
Step 4: For the highest strength bond, spray the bead and the drywall with a medium coat of 847 Spray Adhesive (the only approved adhesive
for Trim-Tex bead installation). If you find it easier to spray the drywall only, spray a medium-heavy coat on the drywall. This method isn't as
strong as spraying both surfaces. Immediately (while the 847 is still wet) install the bead making sure the mud legs are sitting flat against the
drywall, and there is no air gap between the drywall and the bead. To ensure proper bond, pressure the mud legs twice using the Trim-Tex
Installation Tool or the handle of your mud knife.

MITERING INSTRUCTIONS:
• Begin by sniping the mud legs back so they don’t overlap other mud
legs on your 3 way corner.
• Snip to the nose of the bead and not through the nose, for the
perfect outside corner.
• Install the bead as instructed in the above instruction.
