→Tile Flooring
Tile flooring is not recommended in a small fibreglass hull, due to the twisting and flexing. It could work in a 50-ft or larger steel boat. While in a home tile can be bedded in a mortar over plywood, plywood contracts and expands too much in a boat to provide a firm footing. This, plus vibration, can easily crack mortar and tiles.
In a larger boat, cover the plywood (min 3/4-in) or SIP sole with a rubber membrane and then 1/2-in of impermeable cement board such as the original Wonderboard [34]. <ref>http://www.custombuildingproducts.com/tds/tds-106.pdf</ref> Leave 1/8-in expansion space between sheets and caulk between them. Attach the tile with a multi-duty acrylic-modified thinset. Consider means of isolating tiled sections from each other with wooden expansion strips, and from steel stringers with neoprene.
