Forum Title: Sheetrock Green Top
We have been using this compound forever, and in conjunction with a Porter Cable sander for the last 12-14 years. About a year ago we came across a job where the sander put more of a polish on the compound during the sanding. It would smoothen it, but looking across it in the light it would have a shine and not the normal dull finish. You could also see the layers of the compound much more than I can ever recall, like each layer had a slightly different color. You could also feel a slight level difference at these layering lines. We really have changed nothing. Still use 120 grit and still put the compound as we also have. Still using the same sanding pads we always have also. The problem is, every job since then has been the same, even very small jobs. I used to get a whole house out of a single sanding pad, now I have to change 3 times or else the polishing gets very bad. Has anyone else experienced anything like this? Has the composition of the compound changed?
