Millennium Sprayable PVC Single-Ply Bonding Adhesive

Surface Preparation: All work surfaces should be clean, dry, and free of dirt, dust, debris, oils, un-adhered coatings, deteriorated membrane or other contaminants that may result in a surface that is not sound or is uneven.

1. Shake adhesive canister for 30 seconds prior to use.
2. Connect spray applicator to hose and connect hose to adhesive canister. NOTE: Must use a stainless steel braided metal hose - contact H.B. Fuller for details. Open valve on canister to check fittings for leaks. Keep adhesive canister valve open to maintain pressure in the hose/spray applicator when not in use. Once valve has been turned on, do not turn the valve off until the adhesive canister is completely empty or proper cleaning is performed. Refer to guidelines on canister label for cleaning.
3. Millennium Sprayable PVC Single-Ply Bonding Adhesive can be applied at ambient temperature of 40°F and above. Adhesive canister temperature must be at least 70°F prior to use and for the product to spray properly. Utilize H.B. Fuller Warming Blanket, and hot boxes when necessary. Substrate must be clean, dry, and free of debris and contaminants.
4. Adjust the spray pattern/fan by slowly adjusting trigger lock to the desired pattern. Lock trigger when not in use.
5. Visually target the “Correct Amount of Adhesive” coverage pattern detailed in the image below to both membrane and substrate. Apply adhesive with proper overlap to ensure adequate adhesive coverage. For vertical surfaces apply adhesive in a heavier application.

6. For applications taking place in ambient temperature below 70°F, store adhesive canister in heated space and move to project area during application. Adhesive canisters must be kept warm on the jobsite. Dispense product from canister while it is still warm. When product in canister becomes too cold, it will begin to spit rather than spray. If this occurs, swap cold canister for warmer one and return cold canister to heated area. When changing canister,close the valve on the canister and depressurize the hose completely. Remove the hose and attach to the new canister. Open valve and perform a test spray.
7. Allow Millennium Sprayable PVC Single-Ply Bonding Adhesive to flash-off until it does not transfer to finger when touched. Limit application to surfaces that will be covered with membrane the same day.
8. Follow OEM membrane manufacturer’s guidelines when laying membrane into adhesive.
9. Read Product Information Sheet and Safety Data Sheet before use.

Approved Substrates

• Polyiso
• Polyiso HD
• DensDeck® Prime
• SECUROCK®
• OSB
• Plywood
• Metal
• Residual asphalt
• Masonry
• Most gypsum based cover board​​​​​

Approved Membranes: PVC and PVC Fleeceback membranes

The adhesive is applied in a variable web spray pattern via a selfcontained spray system. Product is applied full coverage to adhere PVC and Fleece membranes to approved insulation, cover board, OSB etc. The adhesive must be applied to both the membrane and substrate to which it will be mated. Once dry the membrane can be mated to the substrate and brushed in.

Not for use on EPDM, TPO, or KEE membranes.

Hose, applicator tip, and spray applicator must be purchased separately.

• Coverage rate is 1,000ft2/canister for finished two sided application when laminating smooth field membrane to board stock/substrate. Coverage rates may vary with fleece membrane.
• Coverage rate is 750ft2/canister for two sided vertical wall application when laminating smooth field membrane to wall substrate. Coverage rate for this application is decreased due to increased overlap of spray pattern for the vertical application.
• Coverage rates may be lower when used over irregular surfaces and will vary depending on roughness of membrane/substrate surfaces.

• Store canister in a safe, conditioned space with temperature maintained above 70°F. Do not store canister in areas where temperatures reach 90°F or higher. Contents are flammable. Store in accordance with local, state, and federal regulations.
• With the hose and applicator attached, keep canister valve open to maintain pressure in the hose and spray gun. Periodically spray in a safe manner to help prevent possible clogging. Keep spray applicator trigger locked when not in use.
• Shelf life is 12 months in unopened packaging and stored at temperatures of 40°F to 90°F.

Short Term Storage: 

1. Leave valve on adhesive canister open and lock applicator so trigger cannot be engaged.
2. Make sure to clean spray tip in a well ventilated area using appropriate PPE.
3. Remove spray tip by removing retaining nut. Clean spray tip and retaining nut by soaking in appropriate solvent (ketone, aromatic, etc).
   • Spray tip may require manual cleaning with appropriate sized probe (small wire or pipe cleaner) to help remove build up.
   • An aerosol solvent based cleaner may also be used to help remove build up.
   • Recommend H.B. Fuller’s EternaClean or equivalent.
4. Clean applicator tip and threads with appropriate solvent.

Long Term Storage:

1. Make sure to clean applicator/hose assembly in a well ventilated area using appropriate PPE.
2. Close valve on canister and engage trigger to completely relieve pressure on applicator/hose.
3. Diskonnect the hose from the canister outlet.
4. Remove spray tip by removing retaining nut. Clean spray tip and retaining nut by soaking in appropriate solvent following instructions detailed in “Short Term Storage Cleaning”.
5. Connect hose to outlet of Millennium Canister Flush Solution; tighten with a wrench using caution not to over tighten.
6. Open canister valve fully on flush cylinder and squeeze handle of spray applicator to allow flow of flush solvent through hose.
   • Flush an adequate amount of solvent through the hose into an appropriate collection container.
7. Once flushed, close the flush canister valve, and engage trigger to relieve pressure on applicator/hose.
   • Make sure to collect all flush solution into an appropriate container.
8. Diskonnect the hose from the canister outlet and drain any residual flush solvent into an appropriate collection container.
9. Clean applicator tip and threads with appropriate solvent.
10. Read Product Information Sheet and Safety Data Sheet before use.
