MATERIALS NEEDED:
1. Prime-Flex material.
2. Pail or plastic bag.
3. Rubber Gloves
4. Oil Free Oakum , Open Cell Urethane Foam, or Burlap.
5. Screwdriver and Hammer
INSTALLATION TECHNIQUES:
1. Clean the area in the joint. Dust, laitance, dirt, grease, and any chemical contamination must be removed. Be sure to remove any unsound concrete. (Cut a "V" joint around the pipe if there is not enough room to insert the oakum when sealing around a pipe.)
2. Cut the oakum (foam or burlap may be substituted) into sections that are the proper size for the job and put it into the pail or plastic bag.
3. Pour enough Prime-Flex onto the oakum to cover it up entirely (approximately 1-3/4 gallons for every 10 feet of oakum). Let it soak up as much Prime-Flex as possible. Be sure to wear rubber gloves while handling the activated oakum. Avoid breathing urethane vapors and use adequate ventilation.
4. Take the Prime-Flex saturated oakum out of the pail or bag and submerse it in water for 10-60 seconds.
5. If the joint is dry, spray it with water before inserting the activated oakum.
6. Remove the oakum from the water and force it into the joint or between the pipe and concrete. Drive it in as deep as possible using the screwdriver and hammer.
7. The Prime-Flex will expand and bite into the wet concrete to achieve a tenacious bond. This will prevent further water infiltration at the joint or around the pipe.
