Unsanded Grout Guide

Smooth cement grout for narrow joints and delicate tile, with a creamy texture and a gentle touch on polished surfaces.

Unsanded grout is cement and pigment without sand, which makes it smooth, sticky and easy to push into narrow joints. It is used where lines are an eighth of an inch or less, such as on many wall tiles and polished stone, and where sand might scratch a soft finish. It clings well to vertical surfaces and gives a clean, fine line that suits mosaic and glass tile.

The trade-off is shrinkage and strength. In wider joints, unsanded grout shrinks and cracks as it cures because there is nothing to hold it together. It is also softer and wears faster on floors. Like all cement grout, it is porous and needs sealing. Used where it belongs, in narrow joints on walls and on delicate surfaces, it is a good, economical choice, and it can be recolored or repaired when it ages.
