Sanded grout is grout with very fine sand added to increase density and strength. It is used for spaces between (grout line) tiles that are wider than about 1/8th of an inch (about 1/3rd of a centimeter).
Be careful of scratching tile surface with grout. There are numerous varieties of grout. Some brands won't scratch anything. Know what you're after before heading out to the home improvement stores.
Also, don't forget the hardy backer boards for certain surfaces. The spacers also come in different sizes. Once, you've decided how much space will be in between the tiles, you'll know what size spacers to buy and the type of grout (and grout color). Grout sealant is a must also.
