Subfloor


Okay, I recently removed all of my old subfloor using a combination of tools including a toe-kick saw, jigsaw and chisel. It was impossible to get the old sublfloor completely flush with the bottom plate. When I put down the new subfloor there are gaps in between the new and old. Is this okay? and would I just fill the gaps with something? Also, what length of screws are usually used for the subfloor?

Since a Toe Kick saw can cut right up even to the plate there's should be only tiny gaps.
Once you install the tile board, tile, caulking, base boards and 1/4 round the gaps are covered up.
There should also be insulation under that floor.

The worst gap is a little under 1/2".

Not sure why it could not have been cut tighter and at this point it does not matter. It will be fine, just make sure the tile board gets cut to fit.
I did not see any screws or nails in that subfloor. (you may have been doing a test fit.
It needs fastners every 4" on the edges and from 6 to 8" in the field.

Just a test fit...and that toe kick saw is a beast and has a mind of it's own. It kicks like nothing I've ever used before so I was just happy to get around the room without dying lol. Are too many screws a bad thing? I put up some blocking and was going to attach to that as well.

I hear about Toe Kick kicking back on here all the time, for some reason I've never had it kick back on me or any of my guys, but it only take one time for a bad day.
It looks like this is not the subfloor (may be just the blocking I see in the picture) Is it really the underlayment?
The reason I'm asking it there attached differantly.
Sub floor gets screwed to the floor joist.
Under layment never gets attached the the floor joist. It's attached between the floor joist. The reason is your trying to draw the two piece together and get rid of the gap between the floor joist.

Yea, the only underlayment I will have is Ditra for the tile but I haven't purchased that yet.

Is that "subfloor" t&g, or regular square edge? Looks like regular 3/4" ply to me. Did you install blocking under the short ends of the new ply too?

Regular yes and blocking will be installed on the ends as soon as I put it down for good.

In the future always use Advantec for the subflooring and if your adding 1/2 or 3/4 underlayment always use T & G.
This will make the floor rock solid.
