| 520 | 0 |a"A problem of delayed and recurring localized discolouration (staining) of finished drywall surfaces has been investigated. Biological and physicochemical methods used in the investigation, showed that the stain was chemical in nature. Various factors involved in the staining were investigated including: UV radiation (from natural or artificial sources), humidity, temperature, airborne contaminants, life style of the occupants, as well as paint application techniques. Laboratory simulation experiments were carried out to investigate the stain causing mechanism. These experiments, in conjunction with a chemical analysis of the stain, have shown the direct cause of staining to be due to the interaction of labile constituents in the jointing compound with chemical constituents in the air."--Executive summary, page v. |
