For Bullnose
Corner Beads
Usage Instructions see page 1
To properly
use the Miter Marker on Bullnose L Beads you will need a sharp pencil,
yellow aviation tin snips and a small T square. The instructions are
identical for L Bead and Fast Cap. The only difference is that on L
Bead, there is only one bullnose edge to mark. Place the Miter Marker
on the bead as shown in Figure 1.
The Bullnose Miter Marker comes with alignment edges to allow you to
mark the bead to fit any opening. The alignment edges are marked with
an arrow. First measure the opening inside corner to inside corner as
shown in Figure 2. Mark dimension A on the piece using a T square. See
Figure 3. The 1st mark should be at least 1" away from the edge
to leave enough bead to be cut off. Note, this is a temporary mark and
will not be used for cutting.
To mark for a 90º corner use the outside edges of the Miter Marker.
Slide the tool along the piece until the alignment edge, marked with
an arrow, lines up with the temporary pencil mark. Now mark the radius
with a pencil. See Figure 4A. For a 135º off angle corner use the
inside openings of the tool. Slide the tool along the bead until the
inner alignment edge lines up with your temporary pencil mark. Mark
the radius with your pencil. See Figure 4B.
Place your T square on the bead and line it up with the marks you made
with the Miter Marker as shown in Figure 5. Now make a mark with a pencil.
This is the line you will cut to. As shown in Figure 5, the temporary
marks are shown in red, and you will cut to the green marks.
Snip to the green marks and snip back the legs as shown in Figure 6.
Do not completely cut away the pencil line or the parts may come out
too short. Everyone measures, marks and cuts differently so you may
have to practice on a few pieces. When you dry fit the bead, the bead
may seem a little loose. The fit will become tighter once you install
the bead with a backing of Liquid Nails. See Bullnose Fast Cap or Bullnose
L Bead Installation Instructions for further details. Ideally you should
have a 1/16" gap that will need to be caulked. This will allow
some wall settling without causing hairline cracks in the compound.
Use a paintable acrylic caulk. |
