Do you put underlay under tiles?
A tile floor consists of three individual layers: the subfloor, the underlayment, and the surface tile you walk on.

What nails do I use for tile underlay?
Use 2.5mm x 25mm underlay nails. Drive nail heads flush with the surface. For hardwood floorboards nailing of the underlay is sufficient. For softwood floorboards, plywood and particleboard flooring, it is recommended that the underlay be glued to the floor with wallboard adhesive in addition to nailing.
