I have purchased some #10 2" screws to attach our t&g plank subfloor before tiling.
How often do I need to screw the planks into the floor joists? Joists are 16" oc and planks are 3-1/4" wide. So, screwing every other plank would mean a screw every 6-1/2". Is this adequate, overkill, or a good plan?
1/2" ply to go over t&g, attached with #8 1-1/4" screws, then Ditra, then the tile. I've received advice on amount/spacing of the 1-1/4" screws, but not the 2".
Oh yes, I consulted the Ditra handbook, which was helpful regarding the method, but said nothing about how often to screw the t&g.
Thanks to everybody for your help!
