Application
Temperature
Ideal tape application is accomplished when temperature is between 70° and 100°F
(21° and 38°C). The tape generally reaches full bond strength after 24 hours but
provides a seal immediately. Tape application to surfaces at temperatures below
50°F (10°C) is generally not recommended. Once properly applied, low temperature
holding is generally satisfactory.
Select the Proper
Tape Width
In order to provide a seal, the tape must cover all points of water intrusion. To do this
robustly, the tape should be wide enough to cover the intrusion points and provide for
some variation in workmanship. Choosing a tape width that allows the tape to extend
at least 2 cm (3/4 in) beyond the sealing points can help to accomplish this.
Applying 3M™
Extreme Sealing
Tape
3M™ Extreme Sealing Tape has a release liner on the backing side of the tape.
To avoid overstretching, this liner is usually left on while laying down the tape.
Application Steps
•
Lay tape down so that it covers all areas meant to be sealed.
•
Remove release liner (file cleaning brush can help)
•
Roll down tape with a soft roller (such as a medium nap paint roller). If there is a
step, roll down top and bottom separately.
