Hi,
I am going to lay porcelain tiles onto a concrete floor which used to be covered in the old "marley" tiles. I had to remove these old tiles to maintain the floor level with the adjacent kitchen but that has left the floor covered with the residue of the black adhesive used for those marley tiles. This is not sticky but I am concerned that the Unibond porcelain tile adhesive I have bought says not to use on old adhesive.
One of the previous postings indicated that it was OK to lay directly onto old marley tiles or on concrete where vinyl tiles had previously been laid but what I have seems a little different.
The only advice I have had so far is
to use a latex levelling compound first but I am reluctant to do this as this will raise the level.
Can anyone suggest any other treatment that does not involve raising the floor level?
