Installing the Bumper Bead

Step 1

Snip the Bumper Bead to length and dry fit the Bead into place to ensure an
accurate installation.

Step 2

You can mud set the Bumper Bead using either a Trim-Tex hopper, drywall
compound tube & 90º compound tube head or by hand blading on your drywall
compound to the corner & setting your bead into place.

Step 3

Be sure to keep the attachment surface (or nose of the bead) free of drywall
compound. Finish the installation with drywall compound and sanding.

Installing the Bumper Guard

Hopper Modification for Cleaner Installation

Make two simple saw blades cuts
down the sides of the hopper base
where the mud bumps for the
Bumper Bead would be. This
modification allows the hopper to lay
down a thinner, easier to work with,
layer of mud onto the mud legs,
resulting in a cleaner finish. You
can also get a Trim-Tex hopper with
the base groves already cut out for
the Bumper Bead, just make sure
you specify that with your dealer.

Install Tips:

Mud Set beads are designed to be installed
with high quality drywall taping compound.

Do thin out your mudNOT like you would

with paper faced beads. Mud Set Bead’s hole
pattern allows thick mud to dissipate evenly.

We recommend the following:

Hopper installation - Add up to 8oz of Mud­Max or water per 5 gal. of mud.

Compound Tube Application - 16oz to 32oz of
water per 5 gal. of mud.
