Contractors searching for a TPO adhesive and contractors searching for an EPDM adhesive often land on the same answer. UNO‑GRIP™ | QD2040 is the TPO/EPDM adhesive for both membrane types, including fleece-backed systems. What changes between projects is the layer being bonded, not the membrane name.
One adhesive covers both membranes
UNO‑GRIP™ | QD2040 is the TPO/EPDM adhesive for bonding TPO and EPDM membranes, including fleece-backed systems. The product selection does not change when the membrane changes.
Apply it as directed by the current TDS and SDS, and confirm the membrane, substrate, roof-system requirements, and project documents before installation.
What does change: the layer underneath
Membrane bonding and board attachment are two separate bond lines. UNO‑FOAM® | QD3000 attaches insulation and cover boards; UNO‑GRIP™ | QD2040 bonds the membrane above them.
Identify the bond line first, then select the product for that layer.
Working window for TPO and EPDM
UNO‑GRIP™ | QD2040 has a 2–4 minute dry time and a 1+ hour open time. The UniJet 11002B tip provides an adjustable 7–17 inch spray pattern.
Conditions on the roof affect timing. Confirm the current TDS before spraying.
Coverage and canister planning
A 22 L disposable canister covers up to 10 roofing squares / 1,000 sq ft of bonded area. One roofing square equals 100 sq ft.
For the board layer below, a 22 L UNO‑FOAM® canister covers up to 48 squares.
What this adhesive is not used for
UNO‑GRIP™ | QD2040 is not presented here as a seam adhesive, flashing adhesive, or sealant.
Complete seams, flashings, penetrations, and terminations with the components and methods required by the membrane or roof-system manufacturer and the project documents.
Coverage varies by substrate and application. Confirm the current TDS/SDS, roof-system requirements, and project documents before use.
