Installation Recommendations for Large Size Tiles

PROBLEM: Large format ceramic tiles and natural stones require special attention from the tile setter in order to provide a quality, uniform installation. Special considerations must be given to prevent cracked tiles and slippage.

SOLUTION:

1. The maximum variation in the subfloor should not exceed 1/8" in 10' 0" from the required plane. Bridging high and low points in subfloors can lead to cracked tiles. Floors can be leveled using cement mortar mixtures.
2. Install tile using a 1/2" x 1/2" square notch trowel with a medium bed mortar such as LATICRETE 220, a factory-prepared mortar specifically designed for large format ceramic tiles and natural stones. Medium bed mortars support heavy tiles, reducing slippage problems and providing a thicker bed to help in leveling the tiles.
3. Irregular-backed tiles such as Mexican pavers and ungauged stone also require back-buttering of each tile.
4. Tiles should be "beat in" to ensure proper bond and to adjust the true level of the tiles.
