If the tiles are sound then you do not require screed or any other leveling material. To be sure lay a plastic membrane followed by a suitable underlay. There are a few types of underlay. Basically the thicker the underlay the better it should be but it also becomes more expensive.What do i need to put under laminate flooring if laying over self adhesive tiles on concrete floor, thanks
Assuming you are talking about glueless, click type, laminate flooring, there are two different types of products you can lay under the flooring.





Since you have tile on concrete, let's also assume the floor is relatively flat, and will not need any leveling compound.





1. BEST - MOST EXPENSIVE - a thick dense foam type pad, that comes on rolls. This thicker product is used to not only go under the flooring, to allow it to move,,,but is designed to protect the floor from moisture, and to make the floor ';SOUND'; more like hardwood. It is made to limit the entire floor from resonating sound, a condition called drumming.





2. GOOD - Less expensive - a darker type of foam pad, but less dense. Can be bought by the roll at most big box home stores. This product lets the floor move, and helps protect the floor from moisture. It is not as effective at limiting drumming.





3. NOT SO GOOD IN BASEMENTS - a single ply plastic sheet, thick, but standard plastic. Not a foam product.





A BIG BIG concern. If your basement gets wet, then laminate flooring is not a good choice. While very resistant to in the air moisture, it does not do well under water.





A great place to find information, and even instructions, is

This is name brand for Unilin flooring, a division of Mohawk. Check it out.
you dont have to put underlay down if you dont want to,but,you could put a paper underlay,it comes in a roll just like wallpaper,and is available in the flooring department at a b%26amp;q store.
You will need the underlayment that they sell unless the floor already has it attached to the back of it. Make sure the floor is clean and level-no low or high spots.
KSMARK is right on the mark..Sold aninstalleded laminates for 20 years anthat'sts the way to go..BTW Quick Step is a great product I ve installed over a 100 000 s/f (easily) of it and I ve never had a call back .. GL
I did just this .Had Marley tiles stuck to concrete screed, .I put down a membrane to make sure no moisture could come up. then underlay ,, then the wood . either laminate or real wood ,
well u should screed over the tiles first! then just use any sort of underlay most places will offer underlay at a price when u buy the wood from them
Most carpenters will put down a 1/4'; subfloor. Filling in the joints so its nice and smooth
