We removed two layers of old vinyl, and two more layers of possibly lino tiles from a solid floor in a kitchen.
Left are sizeable patches of a black gunge, might be a glue, might be bitumen, but I can't be sure. It's slightly sticky, but not everywhere.
Area is approx 14 m2 in a 1930s house, concrete floor. I don't think this was a DPM. Floor is otherwise perfectly dry.
How do I remove it before we put a levelling compound on top? Advice from a well respected local tiling shop is:
I'd appreciate some advice.
Many thanks
Mike

- *Remove 'bitumen';
*prime with Mapei Eco Prim grip,
*use Mapei Ultraplan Renovation screed to level the subfloor
*eventually lay sheet vinyl on top (which I bought before I knew what was going to hit me).
I'd appreciate some advice.
