Always choose either a sanded or nonsanded grout based on joint width. Sanded grouts are appropriate for joints at least 1/8″ up to 1/2″. Nonsanded grouts should be used when the joint width is less than 1/8″. You can view the colors we offer at Tile Center at ProSpec.

The width of the joint dictates not only whether the grout should be sanded or not, but also the gradation of the sand. As a rule of thumb: 1/8 or less – non-sanded grout , over 1/8 to 1/2 – fine-sanded grout , over 1/2 to 3/4 – coarse-sanded (Quarry) grout.

The width of the joint dictates not only whether the grout should be sanded or not, but also the gradation of the sand. As a rule of thumb: (1) 1/8″ or less – non-sanded grout, (2) over 1/8″ to 1/2″ – fine-sanded grout, (3) over 1/2″ to 3/4″ – coarse-sanded (Quarry) grout, (4) over 3/4″ to 1″ – (for Handcrafted tile) special mix of 2 to 3 parts coarse sand to one part cement. Always follow the recommendation of the grout manufacturer. NOTE: Sand is added to cement to increase strength and reduce shrinkage; however, the amount and coarseness of the sand is reduced as the grout joint narrows.
