Surface Preparation: Remove all dirt, dust, grease, rust, etc. For high performance a chemically clean surface is required.
Mixing: Mix Part A and Part B using proper mixing ratio either by weight or by volume. Thoroughly blend the two components. Mix 15 seconds after uniform color is obtained
| Mixing Ratios | By Volume | By Weight |
| Part A (Gray) | 3 parts | 7 parts |
| Part B (Off-White) | 2 parts | 5 parts |
Work Life: Work life of mixed materials at 73 degrees F (23 C) is approximately 90 minutes. Large masses and/or higher tempatures will shorten work life.
Application: Use spatula, notched trowel or pressure flow equipment. Apply adhesive at 60 degrees F (16 C) or above.
Cleanup: Remove unhardened material with cloth dampened with a solvent.
Hardening: Only contact pressure is required. Parts must be kept aligned during cure. Mixed adhesive will harden overnight at room temperature (74 F/24 C). Faster cures are obtainable using elevated temperatures. Do not exceed 200 F (93 C).
