So we just put down the backerboard for the new tile floor and shower stall.

We have the Mesh tape for the seams and I forget if you can just tape the
seams as you are laying to tile, or do you have to tape the seams first,
then wait for it to dry then Lay the tile?

Seems like you should be able to do it all at once as your mastic/tape
compound is all the same?

Thanks,
