    I have taken up tiles in the kitchen and some lino. Half the floor was tiles half was lino. Under is what appears to look like black tiles. However they are not tiles. I have read this could be asphalt, bitumen paint or bitumen for sticking down old marley tiles. I am leaning toward it was used to stick down old marley tiles. I have attached some photos. The riles that were down had a blue underlay underneath this was rock solid and brittle ie is chipped and smashed when I got the floor up. Can anyone help me work out what floor I have? What do I need to do with it to screed for LVTs?


    Thanks

    Everything has to come up Be aware these tiles may contain Asbestos I'm guessing this is an older property Its will need a liquid DPM then suitable primer before the smoothing compound is applied

    I was worried about Asbestos after i read that may be the case. Nothing I can do now ive taken them all up. The property isn't too old its 1970ish. I would upload some pics but I cant due to low posts

    thanks. So it’s not a layer of asphalt? Does this change what I do with the floor now it’s all up. Do I need a DPM or can I just screed over

    DPM prime screed is the best root
