COVER TAPE

DESCRIPTION: Cover tape is a laminate of Seam Tape and cured EPDM, rolled on a release liner as “peel and stick” cover strip. Seam Tape is a black, butyl rubber based product developed for use with EPDM single ply roofing. The product has been formulated to provide high green strength in both shear and peel from low to maximum roof temperatures. It is easily applied, offers significant savings and avoids the inherent solvent hazards of contact cements. Cover Tape has been in production and used by segments of the roofing industry since 1984.

SUGGESTED USES: Cover Tape may be used as covers for membrane fasteners, gravel stop flashing, patching, repairing seams and leaking covers, and as redundant and reinforcing seals. Seam Tape adheres well to most types of membrane roofing as well as to other materials of construction, including galvanized and painted steel, aluminum, most plastics, and glass.

PRODUCT BENEFITS:

  • Labor savings.
  • Cured products – Long shelf life.
  • Virtually eliminates use of lap sealant
  • Superior performance over full range of environmental conditions.
  • Superior quick tack from low to high temperatures.
  • Contains no solvent.

*Typical Values: (Based on material tested in our laboratories but variable from sample to sample. Typical values should not be construed as a guaranteed analysis of any specific lot or as specification items.)

METHOD OF APPLICATION: Primer/Activator is formulated for use with EPDM membrane surfaces to be bonded with Seam Tape and Cover Tape and Tape Flashing. Solids suspended in Primer/Activator tend to settle and the primer should be thoroughly stirred before use. During use, re-stir frequently (every 15 – 20 minutes). Primer/Activator should be used full strength – DO NOT DILUTE.

When using Primer/Activator as a primer wash, the EPDM surface to be bonded should be scrubbed with a rag or Scotch-Brite pad (manufactured by 3M) saturated with the primer wash. The surface should appear wet while scrubbing. Clean/prime an area wider than the actual area being bonded to insure bonding to primed surfaces only. Do not merely paint the surface unless the EPDM surface has been previously cleaned. The primed surfaces should be uniformly black without streaks. If the pad becomes filled with dust from the membrane, discard and use a fresh pad.

When using Primer/Activator as a primer (not a wash), the EPDM surfaces should first be cleaned with a suitable solvent such as Splice Cleaner. When the surface is dry, Primer/Activator may be applied with a brush.

Tape can be applied as soon as the PRIMED surface appears dry.

PRECAUTIONS: The solvent used in Primer/Activator are EXTREMELY FLAMMABLE and must be kept away from non-explosion-proof electrical equipment, sparks, open flames, and other sources of ignition. Do not use drill-mounted stirrers to mix the primer. Closed containers can explode when exposed to high temperatures.

Avoid breathing vapors and use only in well ventilated areas. Be familiar with the Material Safety Data Sheet for this product.

HANDLING: Primer/Activator contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary protective equipment and clothing should be worn.

International Diamond Systems maintains Material Safety Data Sheets on all of its products. Material Safety Data Sheets contain health and safety information for your development of appropriate product handling procedures to protect your employees and customers.

METHOD OF APPLICATION:Pourable Sealer is used for sealing objects that are difficult to flash.

Fit membrane as close as possible to the penetrating object (s). Clean surface area of object (s) and membrane using a clean rag with Splice Cleaner or other suitable solvent. Nail membrane to wood nailer if required.
Construct a dam around the penetrating object (s) and mold uncured flashing around the dam. Apply a bread of Lap Sealant around the exposed edges of the uncured flashing where it is bonded to the EPDM sheet.
Stir and pour the pre-measured quart of Part B curative into the pre-measured three quarts of Part A epoxy base.
Stir with a spatula or drill paddle until uniform in color.
Pour the mixed pourable sealer into the pitch pocket and taper the pourable sealer outward for positive drainage. The pourable sealer must fill all voids between multiple penetrating object (s) and must be in direct contact with the penetrating object (s) and the flashing.
The cure mechanism of this pourable sealer is inhibited by cold temperatures. If the pourable sealer is stored at below 40*F, store both components of the pourable sealer at room temperature (72*F) for at least three days before using. Using the pourable sealer at temperatures below 40*F is not recommended and will give incomplete cure, soft spots, and potential leakage.
Do not thin the pourable sealer. Thinning will inhibit the cure and may result in leaks in the pitch pocket.
Clean-up can be accomplished using Splice Cleaner or other suitable solvents before the pourable sealer has hardened.

HANDLING: Pourable Sealer contains ingredients which could be harmful if mishandled. Contact with skin and eyes should be avoided and necessary protective equipment and clothing should be worn.

International maintains Material Safety Data Sheets on all of its products. Material Safety Data Sheets contain health and safety information for your development of appropriate products handling procedures to protect your employees and customers.
