I have just removed a wooden parquet floor laid on concrete and secured with
bitumen. I wish to replace it with Ceramic floor tiles. The problem is how
can I get rid of the bitumen left firmly stuck to the floor. I have got the
majority of it off with a blow lamp and scraper.
What would be the best treatment and what should I fix the new tiles with ?
Most cement base fixings specify a clean dry grease and oil free surface
which clearly mine isn't.
Thank you Mike S.
