My kitchen floor in Vancouver had a weird dip, so I tried a different underlayment
I was installing vinyl plank in a 1970s kitchen last month and the subfloor had a low spot about the size of a dinner plate. Instead of using the standard foam underlay, I grabbed a bag of self-leveling compound from the job site (Ardex Feather Finish, to be exact) and filled just that one spot. It dried in an hour, and the floor went down perfectly flat with no hollow sounds. Has anyone else patched a subfloor like this instead of trying to shim the whole thing?

Yeah, feathering the edges is key like black.wesley said. My buddy tried to patch a bigger dip without doing that and ended up with a noticeable hump, had to grind it down.

Smart move with the Ardex. That stuff is perfect for small dips. I've done the same thing with Henry 547. Just make sure you prime the spot first, or it can flake up later. Key is to feather the edges out real thin so you don't create a new bump. Works way better than messing with shims under the underlayment.
