I just tore up some old tile from my foyer. The tile flooring was installed in the foyer and butts up against the living room hardwood. A long, really awkward transition was put down to separate the 2 areas. The tile was put down on top of thinset and metal lath base. It was a lot of fun to pull up.
The floor under the tile is 100+ yrs old. It's tongue and groove white oak plank flooring. There is no sub-floor.
The hardwood looks like it's OK structurally. However, it's covered in a layer of thinset and has about a million nail holes in it.
I have no idea how to proceed here. Anyone run into this before?
My issues are:
How do I remove the thinset? Sanding, washing, both?
How do I refinish the floor without creating an obvious delineation between the foyer and the living room?
Will the floor survive this process unharmed?
Can I expect any damage from the thinset?
Honestly, the thinset covered hardwood still looks better than the ultra-slippery, fake Italian marble-looking tile that was there. Who puts that in a 120 year old farmhouse?
