Can I fill the gaps and not lay another layer of plywood? I think maybe if I go with ceramic, probably not if I use vinyl.
What type of ply should i use?
If I lay more plywood, what is the best way to adhere it? I have installed vinyl tle before and any seem or nail head make a crease or dimple the tile.
And if I lay new ply, how do I get the seems tight enough to not affect the tile?
Thanks in advance!
