Reuse Mud Bed or Replace with DuRock?
2 Attachment(s)
I am new to the site and new to flooring. We are putting a combination of 20*20" and 13*13" tiles in our entry way. I removed the existing small tiles that were laid in the mid 70's and am wondering how I should proceed.

Do I add a leveling agent over the existing material, or do I remove it down to the subfloor and add durock?

The subflooring is 3/4" plywood over 2*10 joists that are 16 inches apart.

I've attached a couple pictures to give you an idea of what I'm looking at. My gut tells me that I'll need to rip this up and start over, but I don't want to do any extra work if there's little/no benefit.

So a little more research confirmed that I needed to remove the "Jersey" whatever (mortar bed with mesh inside). I've started this process; it's definitely not fun or easy.

Will I need to add a layer of plywood? If so, 1/2 or 3/4". Again the existing construction is 3/4" plywood over 2*10 joists that are 16" on center.

I answered at your other thread and thought it seemed familiar.

One question for you, does this area and the kitchen in the other thread meet someplace?

BTW, that is not a Jersey Mud job. That is a standard mud job.

I would think you'd want to be at the same level as the other room. If so, add 3/4" ply then your 1/4" Durock, if that's what you're using.

Same house. (Big project...)

The other thread is my kitchen. This is the entry on a split foyer house. So no need to correspond with another floor level. I have removed half of the cement so far and will drop some 3/4" plywood and Durock when ready.
