Hi Petra,
I haven't noticed you on the site recently
Busy stripping that floor by the looks of it
Have you tried Mike B to see what Express might have ?
Is it the oil base that's the trouble, oh, and what type of flooring is it ?
I've used a product called 'Floorstrip' with reasonable success and I will check with my supplier to see if suitable once I know about the type of flooring involved.
