CertainTeed AquaBead - Manual

Cer tainTeed
PREPARATION
• AquaBead can be cut
to length using scissors,
metal snips or a chop saw.
Save time by using a chop saw to
cut multiple pieces of AquaBead
to the same length.
• Using a spray bottle or pump sprayer,
completely wet the adhesive side
of the AquaBead
® with clean,
ordinary tap water.
IMPORTANT: Do not use a sponge to
apply water as it will remove adhesive.
Add a bit of food coloring to the water
to make it easier to see where you
have sprayed.
• If you apply less water the working time
is decreased, but the tack (stickiness) is
increased. To extend working time add
more water.
• After applying water, allow 20 – 30
seconds for the AquaBead to activate.
Temperature and humidity may affect
drying times.
• Make sure the entire adhesive
surface on the back of AquaBead
is wet before application.
APPLICATION
• Place the wet, adhesive
side of the AquaBead on
the wall corner, aligning
it tightly to the ceiling.
The beaded edge of the
AquaBead should be squared with the
centre of the corner. Make sure
it is straight.
• Press the AquaBead firmly by hand or
with a roller, making sure the flanges
contact the drywall surface completely.
• REPOSITIONING: AquaBead can be
removed, re-wetted and repositioned if
the adhesive has not set.
• AquaBead adhesive will not stick to
previously finished drywall surfaces.
Use a spray adhesive or joint
compound to adhere to previously
finished surfaces.
• If an area has not properly bonded,
it can be mechanically fastened with
staples before coating.
IMPORTANT: Once the adhesive has set,
the AquaBead will be permanently bonded
to the drywall and cannot be repositioned.
If you have exposed drywall edges, use
L -Trim for a quick and clean finish.
• If preferred, Taping or Mid to
Heavyweight All Purpose Joint
Compounds can be used to adhere
AquaBead. If using this method,
ensure joint compound has thoroughly
dried before applying a fill coat.
Create a guide with a pencil or chalk
line to get straight corners, especially
on bulkheads and long runs.
FINISHING
• AquaBead corner can
be filled after 30 minutes
using All-Purpose or
Finishing joint compound.
• Apply joint compound over the
AquaBead using an 8" – 10" taping knife,
filling the holes. Allow compound to dry
thoroughly.
• Skim over the AquaBead corner
once more with joint compound using
a 10" – 12" finishing knife. Let dry, then
sand and paint.
CertainTeed AquaBead ® is an easy-to-apply, water-activated,
self-adhesive drywall corner that doesn’t blister, bubble, dent or crack.
When installing drywall for 90° corners, hang Outside 90 as shown in Figure 1a. Ensure that the drywall
at the corner does not overlap the joint compound as shown in Figure 1b.
When installing drywall for Bullnose corners, hang as shown in Figure. 2a and 2b. Ensure that drywall at
the corners do not touch creating an open area for the radius of the bead.
