Apologies if I have posted this in the wrong forum! I'm supposed to be tiling a kitchen floor tomorrow. There was a major leak in the pipework in the floor and since taking the old tiles up they have had a dehumidifier on and a heater to dry it out. Is a week enough? The dehumidifier has been off for two days and there haven't been any more damp patches. I'm still a bit worried though. Are there any easy tests I can do to make sure?
