Hi,

I am planning to use Hardibacker between the tile and wood subfloor. I
understand that I need to set a layer of thinset with a 1/4" trowel on
the subfloor and put the board on it before I screw it in. My question
is can I walk on the Hardibacker before the thinset dries? Or should I
wait for some time?

Thanks,

Mike
