From people who actually rolled it on
“Bought it for a small flat-roof section and honestly expected a sticky mess. Instead it leveled well, and the finished surface has stayed flexible through several temperature swings.”
“My brother does roofing. He helped. Said prep looked good and the coating handled nice. I mostly carried stuff.”
“Stirred it, rolled it, added another coat when ready. The foundation looks uniformly covered and the material stayed put on the vertical surface better than I feared.”
