Vinyl flooring / plywood underlayment on concrete install question

Hello,

I'm getting ready to lay the following vinyl flooring in a family room entry and bathroom.

Armstrong Vinyl Tile

The family room is on a concrete slab with no subfloor or anything. It is not below ground like a basement. My plan is to lay a 1/4" plywood on top of the concrete slab and then lay the vinyl and grout on the plywood.

Here is the plywood underlayment I was planning to use. I don't want something really thick.
Plywood underlayment

Is this a good plan? Is there anything else I need to prep the concrete or plywood surface with?

Thank you!

Why do you want to put down plywood? Is the concrete in poor condition?

The floor has old tile that may contain asbestos and I don't want to take it up.

I'm concerned it won't stick. So the plywood would ensure it would since that's what the manufacturer instructions suggest I use.

I think your problem will be getting the plywood down solidly. What is the condition of the old tile and how were you going to attach the plywood?

I'd be drilling holes and screwing it down with 1" or 1 1/4" tapcoms.

You will have a lot of floor prep on the plywood. Remember, any imperfection, even something as small as a grain of sand will show through vinyl.

Do you have any suggestions or alternatives that would work better and ensure a good stick surface?
