Sanded caulk should be used not only on large joints but also whenever the tile it is abutting has sanded grout. Non sanded ceramic tile caulk features a siliconized latex based formula for caulking around sinks tubs and showers and where tile meets tile or another surface.

Unsanded grout also called non sanded grout is made specifically for joints i e the spaces between tiles smaller than 1 8 inch wide grout shrinks when it cures as the moisture evaporates from it and unsanded grout shrinks significantly more than sanded grout. Best for creating wider grout lines sanded grout should be your primary choice for most tiling applications since sand particles have the ability to lock with each other to form a sturdy joint.
