Uncalibrated slate

[robbieraven]

Just wondering what are the tolerances when laying uncalibrated slate, you're obviously not going to be able to slide a 50p piece across it as I test porcelain or ceramics. There are no trip hazards :smilewinkgrin: and I've cleaved off any nasty sharp edges but when opening the boxes of tiles it was really a bloody lucky dip as to what I got, one box was completely unusable. Just wondering what everyone else uses as a rule of thumb?

Guessing there wont be a test as slate is all over the place. just a overall look i guess rather than one tile to the next

Anything more than 1mm just get a chisel to it, a bit of dressing is to be expected with slate.

Thanks Bri, that's what I thought, customer has a glass table and it's in a dining room which I thought was really cool as you'll be able to see the tiles through on the floor, cheers

Why do people go for slate and then expect a flat floor. :mad2:
