How do i prepare a bathroom floor for new linoleum? I have already torn up the previous linoleum. Cheers!?

if the floor is concrete and you have removed all of the residue from the previous floor and you are crack free then glue and lay the floor. If you have cracks then float the floor so that the cracks won't be seen. if the floor is wood then float the floor a few times to make sure that it is smooth and then lay the floor. You can go over existing vinyl with vinyl about 3 times before the floor is to soft and will start to show indentions so keep that in mind so if you want to do the floor over again you will only need cut out any loose areas float over the whole thing and lay the vinyl over the top.
