Well when I did it biogel wasn't around and also there is a story about biogel and steam rooms that I don't know the details of but maybe that is what you're getting at. But if was putting mosaics tomorrow in a non aggressive environment I would without doubt be using isomat ak20 or ak22 . For those of you that have gone nowhere near it or biogel the best thing i can describe it as is the old bal mosaic fix but better as it is more user friendly .
