When current ANSI Specifications call for a different application The now ACT-certified installer politely informed the architect that the current ANSI Specification, A108.02 under section 4.3.8, calls for a much different application. Here follow the criteria excerpt- ed from ANSI A108.02 Section 4.3.8 regarding grout joint size, particularly in relation to the tile size, dimensional precision, and offset pattern: 4.3.8 Grout Joint Size: To accommodate the range in facial dimensions of the tile sup- plied for a specific project, the actual grout joint size may, of neces- sity, vary from the grout joint size specified. The actual grout joint size shall be at least three times the actual variation of facial dimensions of the tile supplied. Example: for tile having a total variation of 1/16” in facial dimensions, a minimum of 3/16” grout joint shall be used. Nominal centerline of all joints shall be straight with due allowances for hand-molded or rustic tiles. In no circumstance shall the grout joint be less than 1/16”. 4.3.8.1 Running Bond/Brick Joint Patterns: For running bond/brick joint pat- terns utilizing tiles (square or rectan- gular) with any side greater than 15”, the grout joint shall be, on average, a minimum of 1/8” wide for rectified tiles and, on average, a minimum of 3/16” wide for calibrated (non- rectified) tiles. The grout joint width shall be increased over the minimum requirement by the amount of edge BY THE BOOK –––––––––––––––––––––––––––––––––––––––––––––––––––––– 100 TileLetter | January 2017
