Research Results Suppressed by Plastering Industry
At poolside inspections, service techs and pool owners are being told by plaster consultants that the light spots and streaking and/or grey mottling discoloration on their new pool plaster were caused by aggressive water. The consultants add that the NPIRC/Cal Poly studies have proven this and that there are no other relevant studies on this type of problem. Of course, this is false on both counts.
Any feed back would be great!
