I am intending to tile a kitchen floor. I have removed the original
plastic/vinyl tiles laid in the 60's I think. The concrete floor is
still covered with the old black bitumen like tile adhesive.
Can I tile straight onto this? I was thinking of priming the surface
with some PVA first. The floor is level but small surface undulations
from the old adhesive. Will the new tile adhesive smooth out into these
small undulations?
TIA,
Tank
