Does the floor feel bouncy? If so. it is. Trust your instincts. It`s not ready for tile. A well built subfloor feels very stiff underfoot. Squeaking can also be a bad sign. but it may also solvable by screwing down the planks or plywood better into the joists.
For tile to be successful. it needs rigid support. with very little tolerance for movement. The more rigid the substrate. the better chance the tile has of remaining crack free throughout its life. Most problems with tile floors over wood come from excessive `bounciness` of the substrate. Carpet can handle some bending. vinyl tile can flex and bend a bit. hardwood floors can bend a little too. but if tile or stone is subjected to forces that push in 2 different directions at once. it doesn`t know how to bend. Instead. it cracks. first in the grout and then in the body of the tile. Consumers who have just paid thousands of dollars for a tile floor do not find these cracks appealing. to say the least.
Tile floor installation is a clear-cut process. Once your contractor has determined your sub-floor can handle the weight and rigidity of tile. he designs a "map" so that the tile is straight. Next. adhesive is spread. and the tiles are "squished" into it. A level is used on each tile to make certain it is flush. and a rubber mallet can tamp down any spot that`s higher than the rest. Spacers are placed between tiles. until the adhesive dries them into place. Border tiles are cut to size and laid. The spaces are grouted. and when it is dry the tiles are cleaned. and sealed.
For plywood subfloors. be sure that the wood is at least 1 and 1/8 inches thick and is supported by an equally strong underlayment. Otherwise. your ceramic tiles will dislodge easily. or worse. break and need replacing. Concrete floors are the most ideal subfloor surface to work with. But before you can start installing ceramic tile flooring over it. it must be cleaned thoroughly. For dust and other debris. sweep and then mop your concrete subfloor surface. and allow it to dry completely. Smooth concrete surfaces must be rough sanded just like vinyl floors to allow the tiling mortar some grip.
