How do you tile over floor boards?

Top tip: When tiling a wooden floor, use a flexible tile adhesive and grout to reduce the risk of cracking. Opt for a silicone sealant around the edge of the room, rather than solid filler. This will allow your tiles to flex as you walk over them, rather than pulling away from the wall or skirting board and cracking.
