Being a military family, we up and move every 3 years. Living in military houseing, we are NOT aloud to paint, put holes in walls, etc. Most of the time we are stuck with cement walls.
3M Command products are amazing! So easy to use, and hold a significant amount of weight. It's just so easy to remove and put back up again, with no damage, no oily smudges, no paint damage. Perfect for kids rooms too! I've used these products on cement, tile back splashes, stainless steel, and drywall, and have had the same results on all surfaces. PEFECT! I stock up on these products when ever I can!
