EZ Purge has a shelf life of approximately one year. To increase shelf life, store EZ Purge in a dark, cool and humidity controlled environment. Ideal storage temperature is 70°F with approximately 50% humidity. EZ Purge should always be stored in the water proof package that is included with purchase. Contact with water must be avoided at all times. For easy reference, the manufacturing date is labeled on the bottom of each EZ Purge box.

If the water soluble EZ Purge dam tears accidentally during installation, simply cover torn spot with Aquasol^® Water Soluble Tape.

It takes approximately 5 minutes for the EZ Purge adhesive liner to dry after being dampened for application.

If the size of EZ Purge does not exactly match the size of the pipe, it is easy to alter the dam to create the perfect desired fit. Simply cut the tape portion of dam as it is being inserted. Then overlap the cut ends to create the desired size. Repeat if necessary. If the pipe ID is slightly too big for the specific EZ Purge size, additional Aquasol^® Water Soluble Tape can be added to reinforce the seal along the pipe wall.

The EZ Purge adhesive is engineered in such a way that it will not inhibit the user from placing the dam in proper position. The strength of the «tack» or stickiness of the adhesive allows the user to have control and reposition the dam if not properly placed on the first attempt.
To reposition EZ Purge, carefully remove the tape portion of dam from the sidewall of the pipe. Then move it to the desired location and apply additional Aquasol^® Water Soluble Tape for reinforcement, if required

If the water soluble tape becomes dry, lightly moisten it with a dampened cloth or foam brush. The adhesive will be reactivated instantaneously. Be careful not to saturate the cloth as the tape will dissolve.

To create a tight seal, first ensure the surface of the inner pipe has been cleaned and that no oils remain. This will increase the integrity of the seal. Once the dam is correctly positioned, the dam can be secured in place by introducing moisture to reactivate the adhesive and form a tight seal. Please note, it is recommended to use a lightly moistened sponge, and not a dripping sponge. Too much moisture will cause the paper and tape adhesive to start to dissolve.

EZ Purge is made from Aquasol^® Water Soluble Paper, which has a flash point of 450°F (232°C).

When welding, the EZ Purge dams must be placed far enough from the root gap so that the heat affected zone (HAZ) does not char or degrade the paper’s water soluble properties.
Recommend distances for placing EZ Purge from the root gap are listed below. These distances depend on the pipe diameter size (ID) or the recommended distance provided by the project engineer to move out of the HAZ.

Aquasol^® Water Soluble Products, including EZ Purge^® Water Soluble Purge Dams, must be flushed with an aqueous solution or steam in order to dissolve. Contact Aquasol Corporation for further information.
