We are so happy with this product! Removed popcorn ceiling, then learned it would cost $650 for skimcoat and paint.  Paid $167 for 64 tiles + glue and finished a 12×14 room in a weekend, and have a beautiful, interesting ceiling! Just caulking to conceal tiny imperfections and we're done!  Planning on buying more and foregoing the popcorn scraping in other rooms.
