The downstairs bog project continues........
House is concrete floored downstairs and covered in horrible thermoplastic tiles. For the most part, they are VERY well stuck down and everywhere else in the house I have got away with localised repairs/levelling around the edges (due to carpet fitters braying nails through them) and then flooring over the top.
Not here though - the tiles are in a right state under the existing cushion floor, probably not helped by the state of the concrete underneath which doesn't look at all good. The only option seems to be to rip them up, and put some levelling screed down. There are only about 2 sq metres of them and getting them up is the easy bit - but left behind on the rough concrete is some kind of black (bitumen based?) adhesive which I doubt the screed will stick to.
I've been attacking it with a scraper and barely managing to get postage stamp sized bits up with lots of effort, and wire brushes hardly make a mark on it as its too soft. Just wondered if there was some sort of solvent for this stuff and/or any other ideas to get it up?
TIA, Midge.
