Laying sticky vinyl tiles on concrete floor

[movieman]

hi,

I would like to put down sticky back vinyl tiles on my kitchen floor. The floor is concrete relatively level within a 10-15mm at most of a slope if any. Wanted to ask advice on laying the sticky vinyl

1. Can i lay it direct onto concrete, should I treat concrete first?
2. should I put down underlay, this will help to level out any small slopes.

Any thoughts would be greatly appreciated

10-15mm isn't relatively level I'm afraid, and you'll find it throws the tiles out. Ideally, you'd put down self levelling compound first, then you'd apply an acrylic primer before sticking down the tiles.

You can't put down underlay, as that'd need to be stuck down first.

Thanks for your reply. Ive already put down srlf levvelling conpound and unfortunately thus is how my floor has ended up. A lot better than before.

What about if I were to put down simple laminate with underlay on to concrete floor

Laminate won't handle that sort of dip, so I'd redo them with a feather edge SLC, then go for the laminate. Feather edge will still be out a couple of mill, and the laminate can handle that, but stick on tiles won't.
