4" hardwood floor boards mounted on a poorly-designed frame made out of whatever wood the constructor had lying around it seems. There's a lot of bounce, some boards even drooping 1/2" when walking on them.
I'm thinking of tiling over with 12" square tiles, maybe 16".
I've never used self-leveling compound before. Would it be suitable to level the floor with this before lining it with 1/4" cement board prior to tiling, or would it seep through gaps between the floorboards?
With the ceiling height already being illegally low at 7', I'm trying not to raise the height of the floor too much.
