Assemblers judge adhesives by grab: does the part stay where it was put, or does it slide or spring back. High-grab construction adhesives and contact cements hold panels on walls without bracing; low-grab products need clamps or tape. Grab blends tack, green strength and viscosity into one gut feel.
This new construction adhesive has no grab, the panels slide down the wall before it sets.
