Hardie backer boards different thickness

[Mrxman]

Hi there

I've bought two 12 mm hardie backer boards for a bathroom wall. I've noticed their thickness is slightly different. The first board is roughly 10 mm while the second one is 11 mm or so.
Is that normal and will it be a problem once I start tiling?

I don't really fance taking the boards back so any suggestions welcome.

Thanks

Technically every board should be between 11.28mm and 12.72mm. But really I wound give it any second thoughts.

Thanks. So you don't think it will be noticable once tile adhesive has been applied etc?
