Millennium KEE/PVC Single-Ply Bonding Adhesive

Millennium KEE/PVC Single-Ply Bonding Adhesive is designed for adhering KEE and PVC roofing membranes to wood, metal flashings, brick or block masonry, insulation, coverboards and barrier boards, and other acceptable substrates.

• Wood
• Metal flashings
• Brick or block masonry
• Insulation
• Coverboards
• Other approved substrates

Approved Membranes

KEE and PVC.

All surfaces to be adhered should be thoroughly dry, clean, and free of dust and loose debris. Membranes and substrates should be free of oil, grease, and other contaminants.

• Not for use on EPDM or TPO membranes.
• Not to be applied direct to expanded or extruded polystirene insulation.
• Do not apply to wet or damp surfaces.
• Do not apply when surface temperatures are below 25°F (-3.8°C).

• Solvent resistant paint roller
• Spray rigs designed to apply adhesives
• Commercially available adhesive dispensers

1. Thoroughly stir the adhesive before and during use. Do not use electric drills to mix the adhesive. Do not thin adhesive. Thinning will affect adhesive performance. The color should be consistent with no solids remaining on the bottom.

2. Millennium KEE/PVC Single-Ply Bonding Adhesive is a contact adhesive that needs to fully “flash-off” before the membrane and substrate surface are joined together. To ensure the adhesive flash-off time is approximately the same, apply the Bonding Adhesive to both surfaces in one application. Bonding Adhesive can be applied using a solvent resistant paint roller, spray rigs designed to apply adhesives or commercially available adhesive dispensers. If the adhesive is spray applied, it is recommended to roll the adhesive with a solvent resistant roller.

3. Position the membrane into place and allow adequate time for the membrane to relax.

4. “Barn Door” fold the membrane onto itself exposing the substrate and bottom of the membrane. Apply the adhesive in a uniform and consistent coat to both the substrate and the underside of the waterproofing membrane, avoiding puddles and light areas. Make sure not to apply bonding adhesive over areas which will be used to create field or flashing seams.

5. Allow the adhesive to fully flash-off and become tacky. Using the finger- push method, check the adhesive by applying pressure with a finger to the adhesive while pushing across the adhesive. Note: the adhesive must be completely dry before mating the membrane with the substrate. Covering wet adhesive and trapping solvent between the membrane and substrate may result in blistering and other surface defects.

6. After adequate flash-off time, roll the membrane onto the adhesive coated substrate and immediately brush the membrane with a stiff bristle broom to ensure maximum contact. 

Millennium KEE/PVC Single-Ply Bonding Adhesive is available in the following package:

A coverage rate of 45 to 60 sq. ft. of finished roof, per gallon, should be expected. Coverage rates will vary depending upon the type of substrate and substrate surface. Some substrates are more porous and will absorb more adhesive resulting in a lower coverage rate. Other substrates have smooth dense facers resulting in a higher coverage rate. Coverage rates are based on applications using a 3/8 inch solvent based paint roller cover.
