In my delivery and Handling article of my 092900 section I've been asked to include replacement of all "water damaged" Gypsum Board. My concern is a need for a definition of water damaged to determine the point of replacement. Is any water too wet or would a soaking be required to trigger replacement. Suggestions? guest (Unregistered Guest) Unregistered guest Posted on Monday, September 19, 2011 - 05:33 pm:    Any water damage is reason for replacement. The water-damaged portion of gypsum board should be cut off and then the remainder of the sheet could be used for patching or in fills.

On current hospital work we always require that any board put in place prior to the building being fully enclosed is a product marketed as mold and moisture resistant. We also very often require that the perimeter board, at inside faces of exterior walls, be mold and moisture resistant types. But most recently, several clients have said "Oh heck" and asked us to make all the board so. George A.
