Tired of that outdated popcorn or textured ceiling? These Styrofoam tiles are your DIY best friend! You get 40 tiles in the box, each measuring 20x20 inches, and they glue directly over popcorn, drywall, plywood, sheetrock, stucco, knockdown — pretty much any ceiling surface. No need to scrape or sand first! They're made of lightweight but sturdy Styrofoam, and you can cut them to fit with just a razor knife. Want them to look like real tin or plaster? Easy — just paint them with any water-based paint (metallic finishes work great for that tin look). Plus, they actually help with sound dampening and add a bit of insulation against heat and cold. It's a budget-friendly way to totally transform a room without a major renovation. Perfect for basements, bedrooms, or that dated rental you're sprucing up!
