sorry to repost ages later in my thread, I did find out it is definitely a sand and cement floor which is why it’s so thick, had to be a minimum of 75mm. It’s been 7 weeks since pouring now and I’m ready to floor tile next week. I have a digital hygrometer on it as well as we speak, it’s been 10 hours, started at 71% and it’s been at 79% for perhaps the last 3 hours so can’t see it going up again now but will check in the morning. What’s everyone opinions as 75% is what I’ve read it should be? Would you risk it being a little higher? I have a dehumidifier so going to get that going 24/7 for the next week after I’ve taken the tester up.
Cheers
