Dilemma?

BROKENHIP

Recently I relocated and have a job that requires prepping a 13 x 13 kitchen, with two layers of secured linoleum, for ceramic tiling, with an ongrade concrete slab sub floor.
This is a humid part of the country so I am slightly out of my element. Here are the solutions I have been offered by the few people that have anything constructive to say on the matter, your input will be greatly appreciated:

1) Tear up the linoleum, glue a 6 mm. poly vapor barrier down, and do a 3/4"-1" mud-job on top(bypassing removal of glue from concrete slab).

2) Tear up the linoleum, degunk, use a spreadable vapor barrier, etc....

3) Go right over the top of the two layers of linolem, a budy thinks it would work well because the exposed linoleum can be cleaned the easiest, and acts as a vapor barrier, it is fastened securely and the increase in floor height is not an issue.

The slab foundation has been in place for years, slippage and settling are not of paramount concern.

your taliking about ceramic tile on lino?

if so, then it's a bad idea.

I would use option 2 and let's not forget an anti fracture membrane.

The bed in question seems pretty solid I was considering an anti shock membrane of course but the building is 50 plus years and the slab is level.
The owner seems to want the project to be a cheap as possible, will the antishock act as a vapor barrier too?
Vapor is the larger concern it seems.

Tear up the vinyl, both layers, then see what condition the floor is in, DON'T use any chemical strippers on the glue, use hot water and a good scraper, come back when it's up and tell us if any cracks and if the floor needs leveling.

DO NOT go over that vinyl and no need for any vapor barriers, maybe a crack isolation membrane, but that's it.

WHAT exactly is an "anti-shock membrane"?

Make sure it's not asbestos based...
