self adhesive vinyl tiles onto concrete

[chinquest]

I have just successfully tiled my living room floor, as a total novice I followed advice from the net laid ply onto my floor boards then laid my tiles. Absolutely delighted and amazed with the results. So on a high I bought some more tiles to do the dining room. A peep under the carpet revealed old tiles while a builder had previously declared that floor as concrete.

Sadly a quick fumble to see how easy it is to remove the carpet fixings reveals the very old tiles are not in a good state and I am going to have to scrape them up. Thus I no longer have the surface I expected to lay my tiles on. Reading around it appears placing plywood on concrete is not a good idea or very easy, I can hammer nails but struggle with drilling and screws. To make matters harder this is the throughfare between kitchen/backdoor and rest of house used constantly by myself and dogs so if I need to prepare floor waiting for things to dry is going to be problematic.

Before I get myself too bogged down is this task likely to be beyond a novice, should I take the tiles back and think of getting a professional to lay lino!!

you could use a self levelling compound to screen the floor first then tile over that. but you would need to keep everything off it whilst it sets

why do you want to lay ply onto concrete ? you only need to overboard floor boards with ply, if the concrete is not good as sugested slc then tile or tile backerboard then tile.

Thank you having looked up Backerboard that would seem to be a possibility

He is laying self adhesive vinyl, not ceramic.

I've removed half the tiles, they were in pretty good condition bar those first ones in the doorway. There is a section that has been concreted upto the tile level, the tiles are about 2mm thick so I am accepting I am going to have to lay a self levelling compound and believe I can do myself. Given the age of the concrete floor over 45 years when they removed chimney breast and leveled to the tiles plus a rather musty smell in one corner, should I be adding damp proof? if so I see you can get liquid damp proof membrane is this the way for me to go?

Removing the glue looks like the most time consuming job how thorough do I really need to be?

Oh I'm actually a newly retired female hence I have the time but lack the experience.

I bought my slc and chatted with the helpful assistant who agreed for the glue removal i was probably best carrying on as I was/am which is bashing it with a hammer!

Problem, in the original dodgy area I have now bashed a hole, this is near the doorway where a kitchen extension has been added, the hole is a good brick width/depth while either side seems solid enough bricks one side concrete the other and I presume will run the length of the doorway (no door it had a sliding door which I had removed) under the wall looks dodgy but assume that is cavity? I haven't delved too deep into the depth of the hole. Amongst the rubble in the hole are black pieces which on inspection I suspect is rotted wood. Now can I bodge this with bricks and cement repair or would anyone say this is serious?

The house is typical 1860's two up two down.
