"I removed my popcorn ceiling and replaced it with Decorative Ceiling ties styrofoam tiles (The Virginian - Styrofoam Ceiling Tile - 20"x20" - #R08) and DIY Foam Crown Molding - 3.5" - #CC 352. This was SO easy to do - I did it all myself and I love the way it looks. On to the next room!" Tips: Make sure you get a strong and fast acting glue if gluing over old popcorn. I ended using Gorilla glue because my ceiling was still a little soft and I didn't want to spend a few more hours priming it just to cover it.. - Crystal L. Wagoner
