1. Before the bead can be installed, additional fastening from the wooden attic stairs
frame to the ceiling joists is required. Make sure there is enough space between the door panel and the frame to install the
bead, without the door rubbing against the bead. Install additional shims between the frame and the ceiling joist to create
solid backing for the entire frame, and then fasten the frame to the ceiling joists about every 4”. The reason for this
is that the frame cannot move or flex independently of the ceiling structure; any movement of the frame could crack the joint
compound applied later.
2. Remove the bead from the packaging and inspect for damage.
Cut the bead to length. It should be about a 1/16” shorter than the space inside of the attic stairs frame. The
perforated corners do not need to touch or overlap. Do not tear away the 5/16” mask of the bead!
The bead supplied with Calvert Attic Stairs already has adhesive tape applied on the perforated portion of the bead. Remove
about an 1” of the paper tape protecting the adhesive and bend it away from the bead; this makes it easier to pull away
once the bead is in place. Place the bead in place, over the edge of the frame and on the drywall. Make sure it is straight,
touching drywall of the ceiling, and against the wooden frame the entire length without any kinking. If everything looks good,
start removing the paper tape protecting the adhesive and apply pressure on the bead to make it stick to the drywall ceiling.
If adhesive is not holding, staples or few nails can be used to hold the bead in place. The perforated edge has to be touching
the drywall the entire length. Slits can be made in the perforated part of the bead if necessary. Be aware that it is not
the adhesive or fasteners that will hold the bead in place once finished; the joint compound will do that.
The bead is now ready to be finished with joint compound; a standard three layer finish is normally required. In a dry location,
the finishing will take at least four days. Each layer will need to dry completely before the next layer of compound can be
applied. If you are not familiar with drywall finishing, please search for help and instructions elsewhere.
the final coat of joint compound is dry, the tear away bead can be removed. Then you may lightly
sand and paint the surface.
