Which primer and screed for laying Karndean over thermoplastic tiles?

[Charlie Brown]

Hi,

I'm wondering if anyone can help me please? I've just bought a 70's house which has thermoplastic (Marley) tiles laid to the kitchen and utility. I'm looking to lay Karndean tiles on top of these tiles (not going to take them up or deal with the bitumen) and would like some advice on how to prep the old tiles. Should the old Marley tiles be cleaned first? Any broken bits stuck down properly and gaps filled? Which primer should be used on top of these tiles? Then which latex screed is best? What adhesive should then be used to stick the karndean down with?

Thanks in advance,

Charlotte.
