 Well. Or flaking and peeling? It's a lifetime warranty. I recertify them every three years. And so you have to recoat. Okay. So there's different looks. So there's what's called a decorative waterproof deck coating or walk decks, catwalks, whatever you want. And the decorative, you can make it look like flagstone. You can make it look like tile. You can make it look like wood. I have another question. I'm so sorry. Sure. Does this just go on decks or can you put it on top of concrete?
