Laminate flooring help needed

[jg96]

I am intending to lay black slate effect laminate flooring over the top of existing ceramic tiles anybody know what type of underlay I should be using

I'v not done any but I'd suggest foam as the first option to go for,it seems common sense.

jg96 - not what I would do to layover - but 3mm foam will be fine

[jg96]

Thanks for your answers folks. I was thinking the thin foam too but just wanted it confirming.Don't fancy taking up the tiles I know they are well stuck down put them down myself around 10 years ago!!

We did the same thing and used the green ones from B&Q , worked well
