Review on 🔗 Fealkira Waterproof Adhesive Wall Hooks – Heavy Duty Stainless Steel Utility Hooks for Towels, Bathrobes, Coats – Nail-Free, Oilproof, Transparent Hooks for Bathroom, Kitchen & Ceiling – 10pcs, Max Load 13.2lb by Ashley Wood

Awesome! I never expected this thing to hold a heavy wreath (20+ pounds) on corrugated (yes, fluted) ceramic tile for the entire 8 weeks the wreath was up. However, I thought it must have something to do with the wreath transferring its weight to the weak point of the hook, which usually yields first under the pressure of the weight it is carrying. The wreath hanger stuck to the glue. I figured it would hold the heavy wreath in place, even though only half of its sticky surface stuck to the wavy wall. I ended up replacing the wreath with a lighter weight wall art held on string by a single adhesive hook. Art fell a few days later. I replaced this art with a heavier one. This time with 2 adhesive hooks in 2 places on the back of the wall. I reproduced a concept that I think worked with the wreath: I placed the weight of the wall art on the weak points of the hooks. The heavier art is still stuck to the same fluted ceramic wall for 3 weeks now.
