had the task of grouting up a wet room floor today it was trav mosaic roughly 4 m2 took me ages! even though I was scraping at the floor with a float the residue was tremendous but it didn't even look like there was any there until I washed off with the sponge it was agonizing lol one wipe on each side and then rinse! think a wash boy will be a god tool for that job.
