Grout joints 1/8″ or larger are typically used for floors. Choosing a wider grout joint for a tumbled-stone installation on a wall can intensify the rustic appeal. When grouting joints 1/8″ or larger, a sanded grout is typically recommended. MAPEI’s Keracolor S and MAPEI’s Ultracolor Plus FA are considered to be sanded grouts. MAPEI Flexcolor CQ grout uses a special type of coated sand and can be used in most installations where a sanded grout is recommended.
