Hello Everyone,

I am laying down from LVP (lifeproof from home depot). Anyway, this is my first time doing it and ive watched about an hour of videos on you tube etc...

Question for this group here, is my house is currently half tile and half carpet. My plan is rip out the carpet, and lay down plywood to flatten out the flooring between the tile and slab (instead of chipping up all the tile), cover gaps / transitions with leveling compound or thinset...

Just want thoughts on this approach... i cant find anything online about doing it this way.

Plywood on concrete won't last very long. Even with minimal moisture it will rot and cause mildew and mold. Is there something wrong with the tile? Assuming it is either ceramic or porcelain. Could you just lay the LVP in the area where the carpet was?

I'm really looking to have matching floors throughout, and i took down a wall so the tile is all messed up anyway.

Why would the plywood rot if its on concrete? Seems like if there was moisture coming in through the concrete, carpet would be wet and would have the same problem...

I am just trying to determine the best way to have a level floor across 1k sq feet so i can put in this LVP down.

Good question, i guess didn't really think about that. I was just going to float it, but now that you mention it maybe some tap cons...

Am I just causing more work to skirt the removal of the old tile?

How will you attach the plywood to the concrete?
We once demo'd a kitchen that was on a slab. They laid osb sheets over the concrete, with no fasteners, then laid hardwood over that. While it came up very easily for us, it remained in decent shape for at least 30 years.

If it was me, I would use a construction adhesive, followed by some short tapcons on maybe 12" centers. For 1000 sq ft, this would be about 1000 Tapcons though.

Yea, definitely wouldn't be doing 1000 tapcons. I was thinking one in each corner of each sheet, just to make sure its not going anywhere.

You likely wont like the results. You will feel as you walk over the movement. Not to mention, plywood has a tendency to "potato chip" and/or delaminate.

You really will be a lot better off, and save money by removing the tile. How much tile is there to remove?

Hi,
Not sure you have your answer, but I am planning on putting the LVP over ceramic tile in our master bath and filling in the area under the vanity with 3/4" OSP to fill in the area that I did not put to ceramic in. I realize I will not be walking under the vanity though, but I think it will work though...
