Do i need cement board under floor tile.

Cement board is a type of underlayment that is now standard for most tile installations but particularly for floor tile. The primary benefit of cement board is that it doesn t break down or expand or warp if it gets wet. I d like to get as close as possible to matching the height of the existing tile. This is the industry standard most preferred by construction pros when installing ceramic or porcelain tile backer board comes in four foot by eight foot and three foot by five.

Cement board also provides an additional layer over a plywood or particleboard subfloor adding stiffness to the tile. On top of the 2 6 will be 3 4 subfloor thinset cement board redgard thinset tile.
