The document provides tips and information for installing rectified tile, including: 1) Rectified tile undergoes an additional manufacturing process where the tile is cut or ground to very tight tolerances, assuring limited size variation. 2) Recent revisions to tile installation standards now include a category for rectified tile and provide more realistic expectations for products and installations. 3) When installing rectified or large format tile, use appropriate substrate preparation, thinset, grout joints, and movement joints to accommodate natural variations in tile size and substrate flatness.

8. Rectified Tile Has an Additional Manufacturing Process Or ground to very tight tolerances

9. Dimensional variation occurs in ALL TILE Rectified tile’s cut or ground edges assure limited size variation

10. Recently revised American National Standards provide realistic expectations for products

11. This recent revision now includes a category for Rectified Tile

12. Products need to be coupled with realistic expectations for installation

14. Grout joints are required for variation in the tile and substrate

15. Lippage Allowances (minus warpage) 1/32” of an inch is .0312 or about the thickness of a credit card 1/16” of an inch is .0625 or about the thickness of a penny Tile Type Tile Size Grout Joint Width Allowable Glazed wall/Mosaics 1” x 1” to 6”x6” 1/8” or less 1/32” Quarry 6” x 6” to 8”x8” 1/4“ or greater 1/16” Paver (porcelain) All 1/8” to 1/4“ 1/32” Paver (porcelain) All 1/4“ or greater 1/16”

22. Select appropriate floor fill material It is much easier to flatten the floor rather than flatten the tile
