Application Method

Surface Preparation

Membrane and penetration surfaces must be clean, dry and structurally sound, free of contaminants, including but not limited to dust, dirt, loose particles, rust, oils, etc. If substrate is coated, scrape away all loose and weakly bonded coating. Any coating that cannot be removed must be tested to verify adhesion of the sealant or to determine the appropriate surface preparation if needed.

When Millennium 1-Part Pumpable Sealant is to be used to repair or coat a Lockin’ Pocket® Sealing System installlled on a single ply membrane, the surface of the membrane must be prepared according to the single-ply manufacturer’s recommendations. As a general guideline the following methods of surface preparation shall apply:

  • EPDM: Clean with splice wash or surface cleaner and prime.
  • TPO: Clean with surface cleaner and prime.
  • Gravel BUR’s: Remove gravel surfacing down to plies.

For applications over existing weathered asphalt or coal tar pitch built-up roof membranes apply Millennium Universal Primer prior to 1-Part Pumpable Sealant application. For applications over fresh or non-oxidized asphalt, coal tar pitch, or plastic film membranes, apply Millennium Surface Treatment prior to 1-Part Pumpable Sealant application.

Method

1. Cut nozzle to desired size and puncture seal inside the nozzle.
2. Refer to Millennium Lockin’ Pocket® Inter-Locking Flashing System product data sheet for complete application instructions if 1-Part Pumpable Sealant is to be used in conjunction with Lockin’ Pocket® Sealing System.
3. Gun/pump Millennium 1-Part Pumpable Sealant into void and fill to required level. The entire void must be filled. No grouts or fillers should be used in conjunction with Millennium 1 Part Pumpable Sealant.
4. In order to properly waterproof, voids should be filled with a minimum of 2” (5cm) of Millennium 1-Part Pumpable Sealant in accordance with all of H.B. Fuller’s current application instructions. Apply Millennium 1-Part Pumpable Sealant in a continuous operation to avoid air entrapment and overlapping.
5. Option for white Lockin’ Pocket®: Coat the surface of the Lockin’ Pocket® with 1-Part Pumpable Sealant. Trowel/spread as necessary to achieve desired finish.
6. Millennium 1-Part Pumpable Sealant will form a skin on the top surface within 60 minutes of initial installation. Full cure rate is approximately 1/4” (0.6cm) per 24 hours depending on relative humidity and temperature.
