Step 1: Float out any large dips in
the drywall. Take a short scrap
piece of Magic Corner (6" long)
and make a pencil mark along the
leg of the Magic Corner at both
ends of the run.

Step 1: Dry fit the Magic Corner and
cut to length. Apply a coat of multi­purpose compound to the wall. Add
Trim-Tex Mud-Max (Stock # 850) to
your drywall compound to increase
its strength and durability. Do not

use fast setting compounds as
they tend to be Brittle.

Step 2: With a chalk line, snap a

line along the two pencil marks.
This will ensure a straight corner.
Cut the Magic Corner to the
desired length. Remember, 200’
rolls mean no butt joints.

Step 2: Using the large radius end of the
enclosed Installation Tool, roll the Magic
Corner into place as shown above. The
Magic Corner should align itself straight
along the run. Sight line and make any
adjustments if necessary.

Step 3: Liberally apply Trim-Tex 847 Spray Adhesive first on
the Magic Corner Bead and then to the drywall. Immediately
apply bead to the wall using the chalk line as a guide, and
press down both mud legs with the flat end of the enclosed
Installation Tool (See above right). Allow adhesive to tack
up 1-2 minutes. Press both mud legs a second time and
then staple both legs every 6-8" with 1/2" long divergent
staples. See Finishing section for mudding & painting.

Step 3: Press down the legs with
your taping knife. The compound
should squeeze through the
holes in the mud legs. See
Finishing section for mudding &
painting.

Remember To Use Mud-Max

Mudding: Always use multi-purpose compound to mud Magic Corner. Do not use fast setting
compounds. Add Trim-Tex Mud-Max (Stock # 850) to your drywall compound to increase its
strength and durability. Between coats, use the pointed tip of the Installation Tool to clean the
mud out of the flexible center of the bead as shown to the left. The center must be clean of mud
for the product to function properly.

Painting: Magic Corner is designed to be an expansion joint to prevent expensive call backs to
fix cracks in the drywall. The pliable center is designed to expand or contract as much as /4" -

3

/8". Since paint is not very flexible, please follow the guidelines below to ensure satisfactory
results. For the ultimate performance, brush in the center of the Magic Corner with an exterior
acrylic semi-gloss paint. Always use high quality paints as they bond better and have more
flexibility than more inexpensive brands. Do not prime the flexible center of the Magic Corner. If
applying primer by spray, try not to spray any primer into the flexible center. The heavier the paint
is applied, the worse the paint will perform. Brush in a coat of the final paint color.
