From what I understand Mohawk is one of the sticklers for their glue and they do not specify any other glue than their own. If you use any others then you are left to the warranty that the glue manufacturer provides.
Here are their instructions:

And here is the important part of the warrantee:
Quote:
Moisture Warranty
Mohawk Industries, Inc. hereby warrants to the original buyer of Mohawk engineered and longstrip wood flooring products against moisture damage due to topical spills or subfloor moisture under certain conditions for as long as you own your home.
Topical spills of normal household substances (food and beverage) must be removed promptly. Topical spills allowed to remain on the floor for any considerable time will damage the floor and void this warranty. Flooring must be installed following the Mohawk installation instructions. Plumbing accidents, leaking appliances (icemakers, dishwashers, clothes washers, etc.) are not topical spills and are not covered by our warranty.
Subfloor moisture, particularly from concrete slabs, is covered by this warranty under the following conditions: 1. The floor must be visibly dry immediately prior to installation. 2. The installation method used is the direct glue down application. 3. The installer must use Mohawk Professional Choice adhesive to install the Mohawk engineered wood floor. 4. The installer follows the Mohawk installation instructions and the instructions specified on the packaging of the Mohawk Professional Choice adhesive.
If the floor fails due to the incursion of moisture from the subfloor, Mohawk Industries will replace the damaged material at no cost to the "Buyer" one time only. This includes material only. Labor is excluded from this warranty and labor costs must be incurred by the "Buyer". Please note that this applies to engineered and longstrip wood only. The solid wood products are not approved for direct glue applications.
This limited warranty does not apply to Cabin grade or other downgraded or discontinued items. Any such Product or Products are sold "as is". MANUFACTURER HEREBY DISCLAIMS ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING ANY WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE WHATSOEVER.
Any and all representatives, promises, warranties or statements by Manufacturer or its agents that differ in any manner from the terms of this limited warranty shall be of no force or effect unless in writing, signed by a duly authorized officer of Manufacturer.
Pretty much if you use anything else you are up the creek with them.
