VINYL CORNER BEAD ARCH
BASIC INSTALLATION GUIDELINES
#10513
#70081
Practice installation in accordance with applicable ASTM standards and using prevalent industry standards.
Staple Attachment
For regular (not bullnose) archway corner beads, drywall does not need to be set back
For doors, windows or special lengths, cut the bead to length and dry fit
a) Prevent overlap of the mud flanges by snipping back
b) Dry fit the bead
Staple the solid mud flange every 6-10" with 1/2" crown staples. Staple each flange segment on the notched mud
flange with 1/2" crown staples.
No primer is needed. Finish as usual.
For cold weather winter applications, please refer to the installation recommendations in the Gypsum Association
GA-220-06 of 40°F or warmer.
Spray Adhesive
For regular (not bullnose) archway corner beads, drywall does not need to be set back.
For doors, windows or special lengths, cut the bead to length and dry fit.
a) Prevent overlap of the mud flanges by snipping back.
b) Dry fit the bead.
Put a coat of spray adhesive on the back of the bead and then on the drywall.
a) Immediately apply bead to drywall and position in place.
b) If the adhesive dries too long, it will be hard to reposition.
c) If the adhesive loses tackiness and will not bond, reapply adhesive to both surfaces.
The rate at which the adhesive dries varies depending on heat and humidity. Test in your conditions.
Use handle of your taping knife or installation tool to apply pressure along both mud flanges. Bond strength is greatly
enhanced with this crucial step.
Staple the solid mud flange every 6-10” with 1/2" crown staples. Staple each flange segment on the notched mud
flange with 1/2" crown staples.
Pressure the mud flanges again
No primer is needed. Finish as usual.
For cold weather winter applications, please refer to the installation recommendations in the Gypsum Association
GA-220-06 of 50°F or warmer.
Archway Cornerbead is slotted (kerfed) to fit smoothly
around a curved surface.
