Hi there, I laid some engineered wood flooring on concrete with Mapei Ultraplan M20 self-leveling compound over a week ago. The bags said zero VOC premixed. There was an awful sweet/fruity chemical smell when I mixed it. I called Mapei and they said it would go away when dry. However, the smell is still here. I would have thought the underlayment (AirGuard Roberts 3-in-1) would cut the smell but it's bad. I need to level plywood subfloors upstairs to finish this job and wondering if anyone can recommend an equivalent product that doesn't stink.
