q & a

  • Why would tape-on bead and trim be used instead of nail-on?

    Nail-on bead and trim is attached to framing (usually wood). They twist and edge crack when the framing moves due to lumber drying and settling. Tape-on bead and trip floats with the wallboard when the framing moves and the building settles. They do not edge crack when these situations occur.

  • What is the best way to remove the protective masking on the back of USG Sheetrock® Brand Pre-masked L-Trim?

    Relax the serrated edge by pre-creasing or folding the strip. This ensures smooth removal of the masking and results in a clear tear that will not damage the trim.

  • What is the warranty for USG Sheetrock® Brand Paper-Faced Metal Tape-On and Nail-On Bead and Trim?

    The warranty is effective for 30 years from the date of the installation in the structure. See complete warranty for details:

  • When installing corner bead or trim, how much space should be left between the trim and the floor?

    Leave a 1/4" space between the bottom edge of the corner bead or trim and the floor.

  • Can paper-faced, tape-on beads and trim be filled with joint compound the same day they are applied?

    Yes, but it is recommended that they set for a few hours before filling.

  • Do paper-faced beads and trims cost more than bare-faced trims?

    Yes, but they require fewer repair callbacks to fix edge-cracked corners.

  • Do I need special tools to apply paper-faced beads and trims?

    No. Tape-on bead and trim can be applied using drywall finishing tools and nail-on bead and trim can be applied using drywall applicator tools.

  • Will the paper on the bead fuzz when sanded?

    No, the patented nose coating on paper-faced bead and trim prevents the paper from fuzzing or when sanded.

  • What kind of paper is used on paper-faced bead and trim?

    The paper is joint tape used in drywall finishing. Joint tape provides the best adhesion for paper to wallboard using joint compound.

  • What are some advantages of paper-faced beads?

    Paper-faced beads provide superior adhesion to joint compound, primer and paint. They have a lower bead height than bare faced beads and trims. This requires less consumption of joint compound when coating the trims. They have an almost non-existent chance of leaching rust through the joint compound and finish paint. Tape-on trim rarely edge cracks, a common problem with nail-on and staple-on bead and trim.

  • What should I do before installing corner bead and trim?

    Make sure wallboard is clean, firm and dry before applying corner bead and trim. Also, verify that the bead or trim is wide enough to cover any gaps in the wallboard.
