Tile over Oak Hardwood floors (unfinished)
I have a 1960's house, original oak wood floors. I had carpet but got rid of it. Wood is in very good condition (as I've been told by experts I've had come over to give quotes). no creaking or anything. Very strong.
My mom and I are HIGHLY chemically sensitive and though we've looked at many types of finishers/sealers (even one with zero voc), we noticed all have a smell, even if it's a strong oil smell. We can't handle it.
Decided to just tile the front room and dining room. Looked into using a backboard that we had another company use to do the entry way. We were going to do it ourselves next week.
Then, I found a video on Youtube that hardwood should be finished to put tile on it because of the water (?) in the concrete/grout? Is this true because on another website I found it says, "if you don't feel like refinishing your hardwood floors, why don't you try tile" and gives instructions.
The man is the youtube video was putting the tile directly on the wood, which we're not doing, but still. I never thought about the moisture until now.
So confused. Obviously, I won't be laying the tile on the wood, but is there anything I can use (along with the backboard) to make sure that none of the wetness goes into the wood?
thanks for your help
