On top of the 2 6 will be 3 4 subfloor thinset cement board redgard thinset tile.
Do i need cement board under floor tile.
The primary benefit of cement board is that it doesn t break down or expand or warp if it gets wet.
Cement board is a type of underlayment that is now standard for most tile installations but particularly for floor tile.
I d like to get as close as possible to matching the height of the existing tile.
Cement board also provides an additional layer over a plywood or particleboard subfloor adding stiffness to the tile.
This is a distinct advantage over plywood and drywall.
If i thinset the cement board down using a 1 4 x 1 4 trowel and screw it every 8 will the thinset end up being 1 8 thick.
