entryway subfloor
I finally ripped up the entry way carpeting, hoping to find a tiles, but instead found the wide plank subflooring with some sort of ancient papery stuff adhered to the wood. It peels off in places, but would be impossible to remove. Before tiling the floor, what do I put over this old, stained papery…

Hello,

Thank you for your patience!
the right way to do it would be to cut out the subfloor with a sawzall and put plywood over the beams, followed by wonderboard…that way you are only 5/8 -1 inch over the original carpet level…ceramic tile cannot be laid over a tongue and groove subfloorwithout the danger of movement popping tiles within a year…ardex is nothing more that self leveling concrete and has absolutely no strength or stability characteristics..if you want to take a chance, at the very least screw and glue 5/8 wonderboard over the existing subfloor and use thinset plus or latepoxy to apply the tile..the nature of finishes is that “the devil is in the details”..
If you use the ardex feather finish it does not add height. I don’t know what you want to put over it – tile? For elevation changes there exist transition pieces, but ideally you want the same height. How thick was the carpet?
We’ve scraped off some of the paper and the wood subflooring seems to be solid beneath it. If we add over an inch to the floor height, how do you deal with the lower floor as you enter the hall? It would be a step down. How do you keep the entryway at the same level as the hall? The hall is currently carpeted and we want to take that carpet up eventually (but not now).
I have some surplus ardex underlayment, used for troweling over substrates. It dries smooth and hard. I’ve used it commercially and residentially. Here’s a link.

I used this product to trowel over concrete that had a lot of old adhesive on it at a college campus – about 1500 SF. It endured the heavy traffic of students. Great stuff.
Let me know if you are interested. I could also trowel it out really quickly for you. It dries in 15 minutes.

what you found is a layer of tar paper, traditionally used as a leveling material over subflooring… if you do not want your tiles ( i am assuming ceramic) to pop off the floor, you need a real stable subfloor condition…a layer of 3/4 plywood glued and screwed over the subfloor followed by a layer of 5/8 wonderboard glued and screwed is the best, with the joints not lined up on the 2 layers..the problem is that you may have to undercut doors and change your thresholds because of the increased floor thickness…in addition, use thinset or latepoxy, not glue to lay down the tiles
