Bathroom Floor Redo #HELP

HEADS UP — i over think things and my posts are sometimes long because my thought process is long ? and with that said,

I just joined the Forum and I have a question regarding something I am sure has been posted a thousand times but here it goes.

-> Warning LONG POST

*TOPIC

-Hardieback Boards
-Thinset
-Liquid Nails
-Vinyl on Hardieback

… my plumber who also does tape and float, floors and other things was going to put a new toilet in my small bathroom but we noticed some of the flooring around the toilet area was rotten out so I had him just put entire new floor of plywood instead of cutting the section out especially since the bathroom is small.

… my original plan was to use peel and stick vinyl squares, and he brought up maybe putting hardibacker on the floor.

… I didn’t know what that was so I did some research and went ahead and okayed putting it on.

… now for some reason I did not continue to research (i should have) and i didn’t know about the recommended thin set layer between the subfloor and the HardieBacker … and my guy used Liquid Nai ls and hardibacker screws because he said he’s done that before with no issue.

… but i didn’t realize is that you can’t use peal stick vinyl squares on top of HardieBacker boards.
* (unless there’s a way? )

… so then I thought maybe I should just go ahead and use ceramic tile from this point forward since I have seen some of his ceramic bathroom floor work and looks pretty good.

… but then he tells me that it IS possible to use peel and stick vinyl squares on top of the hardibacker board by FIRST applying and spreading vinyl tile Adhesive on top of the hardibacker board and then apply the squares.

-> So my questions are:

1. is it really possible to use peel & stick vinyl squares on top of HardieBacker board especially if you’re going to use a vinyl tile adhesive first?

2. What about the issue of him using Liquid Nails between plywood and Hardieback instead of the recommended thinset?

and most importantly since I don’t have the money to tear it off and start all over and since the new floor and the HardieBacker boards are already in place (and actually looks and feels solid)

-> what is your advice to do from this point forward?

Unless U have ideas my only choices are

1. Try the peel and stick vinyl using vinyl adhesive on top and see what happens.

2. Go with ceramic tile

3. or ????

… am i over thinking this?

What The Hell Do i Do Now ?

“My plumber who also does tape and float, floors and other things”-Not trying to be rude, but trust me he is NOT a plumber, or you have VERY VERY deep pockets.

Hardie backer should be set in thinset, however if the subfloor was relatively flat and the Hardiebacker doesn’t have any gaps below it should work fine. If I had to I would much rather remove Hardibacker set in thinset than liquid nails with a good bond to the subflooring.

Why do you want to use peel and stick? I would assume regular glue down VCT tile with a primer would work, never had this come up so you should probably check the tile box and call the manufacturer, (I would think you could use the primer for the peel and stick as well), we don’t get much call for peel and stick! Why would you want to use peel and stick anyway? Also you would have to fill all the screw holes as they would show through over time, and it will crack at the joint.

As you said the floor is solid, If you or your guy fe el capable of installing ceramic mosaic tile you could go that route as well, I am sure there are plenty of how-to videos online.

Hope this helps.
