The distinction between TEC AccuColor sanded and unsanded grouts is determined by the joint width of the tile installation. AccuColor sanded grout contains fine-graded silica sand, which provides the structural support needed to keep wider joints (1/8 to 1/2 inch) from shrinking, cracking, or breaking apart. If you try to use sanded grout in joints narrower than 1/8 inch, the sand particles will act as an obstruction, preventing the grout from filling the joint completely and leading to ugly voids. TEC AccuColor unsanded grout is specifically formulated for tight, narrow joints between 1/16 and 1/8 inch. It uses fine-graded minerals rather than sand, which allows it to flow easily into tight spaces. You should never attempt to use unsanded grout in wide joints because the lack of sand aggregate will cause the material to shrink as it loses moisture, leading to severe cracking and a loss of integrity. Always measure your grout joints before you choose your product, as the correct choice is essential for the long-term beauty and durability of your tile floor. If you are unsure, consult the manufacturer's technical instructions or a professional installer.
