This is a stupid idea. I know it's a stupid idea. Please don't reply just to tell me how stupid it is.TL:DR; I want to cover the floor drain in my basement with plastic sheeting, then pour some kind of rubber/silicone/urethane/bendy-plastic over it, to create a removable cover or plug of sorts. (If it didn't need to be removable I'd just use self-leveler) I don't expect it to actually plug the drain water-tight. I just want to smooth out the slope of floor so I can put cheap vinyl plank flooring over the drain and pretend it's not there. What kind of material can I buy to do this? I've done some googling and it seems theres a million choices for casting and mold making. Any suggestions would be greatly appreciated.My basement floor is unfinished concrete. It's mostly flat except for the ~4-foot circle around the floor drain, where it slopes down towards the drain. If I sit a 4' level across it, there's about half an inch gap in the middle.I want to put vinyl plank flooring over the whole basement floor, because it's relatively inexpensive, durable, waterproof, etc. Unfortunately it will not work over such a steep slope around the drain. The boards are not flexible enough to handle the gap.I was talking to a painter friend of mine (house painting, not art on canvas painting), and he used to do epoxy garage floors for a living. He said they used to just cover floor drains with masking tape, then pour on some self-leveling concrete and seal it off. That sounded like a great solution, but I'm worried about permanently closing up my floor drain. What if I have a pipe leak or something, and I need that drain some day?So my thought was to do the same thing, but with some kind of removable material. At first I thought just put down plastic sheet, and still use the self leveler concrete. But I think that will just end up too brittle and crumbly if it's not adhered to the concrete slab floor. So I thought maybe some kind of stiff rubber would work. Then I could remove it if I had a sudden need to drain something. (The vinyl plank flooring is not glued down, it just clicks together. So I could pull up the floor boards and remove the drain "cover")I've googled a bit, but it's very overwhelming. Smooth-on seems to make thousands of products that all seem very similar. I'm thinking I probably need something pretty firm, so I've been looking at products with about 60A shore hardness or greater, but that still doesn't narrow it down much.I know this is a ridiculous idea, but any and all suggestions would be greatly appreciated. via /r/DIY http://ift.tt/2xMttEi
