HELPFUL TIPS FOR HANDLING BUTYL TAPE |
|
*Scissors are best
for cutting Butyl Tape |
|
*Always cut Tape with
release film attached |
|
*Wet the blades with
paint thinner to prevent Tape from sticking |
|
*Wet fingers with
paint thinner when handling Tape without release film
attached to prevent sticking |
|
*Use needle nose
pliers to remove release film when working in confined
spaces |
|
*Use a wooden or
metal roller to press tape to surface for better adhesion |
|
*Tape can be
overlapped to cover a wider area |
|
*Always reinforce Tape with Fabric to eliminate stretch |
|
|
|
USING BUTYL TAPE AS AN ADHESIVE |
- Clean substrate and underside of part with paint thinner.
- If surface temperature is cold heat with a hair
dryer until barely warm to the touch.
- Cut Butyl Tape to approximate size of part and lay
it on a flat surface with the sticky side up.
- Press part onto Tape and trim excess with scissors.
- Remove release film.
- Lay part into place starting at one side to avoid
trapping air bubbles and press onto surface for better
adhesion.
|
|
TO REATTACH A TEAR IN A MEMBRANE: |
- Cut convenient size pieces of Tape and slide under loose
membrane with release film attached.
- Start at one end and successively remove the release
film while gently pressing membrane onto tape.
- Roll surface for better adhesion.

|
SEALING JOINTS, SEAMS, OVERLAPS AND TEARS |
|
Surface Prep: |
|
|
Metal, Fiberglass, and Masonry
Use a wire brush or sandpaper to clean surface and
create a slightly rough surface. Then wipe with paint
thinner. |
|
|
Rubber and Thermoplastic Membrane
Remove surface chalk by wiping repeatedly with rag wet
with paint thinner. |
- Center the Butyl Tape over the seam and press onto surface
with a solid roller.
- Do not remove release film until ready to apply
Fabric.
- Remove a section of the release film and center the
rolled Fabric over Tape and press onto Tape.
- Alternately remove more film and roll out Fabric
until all Tape is covered.
- Use roller to firmly embed Fabric to Tape.
- If Fabric begins to go off center cut it and
realign.
- Topcoat the reinforced Tape with Liquid Roof® or
EPDM Liquid Rubber® plus 2 inches beyond to complete the
repair.
