I'm doing my kitchen floor this week and have taken up the old vinyl tiles as a few were missing bits, and a few missing entirely ( under the old units )..
this has left me with a black tarry like substance on the concrete floor which I assume was the adhesive for the vinyl tiles..
do I need to do anything to this before tiling over it ( ceramic tiles )?
