Dave the Grout Guy

Grout plays an important part in floor stability, as well as the finished appearance.   The rule-of-thumb, when choosing grout types, is non-sanded grouts are for narrow areas up to 1/8"; sanded grouts are for areas ranging from 1/8" to 3/4" or more.   However, because of the type of sand in the Portland cement, which makes this type of grout more stable, sanded grout can be used in wider spaces. When using a polished marble, only non-sanded grout should be used.   This is because sand can cause scratching.   When restoring natural stone, the grout can become loose and scratch, especially, polished marble.

There are many different colors and brands from which to choose that may compliment the tile or stone in your home or business. Remember, when choosing a colored grout, greens, blues and some of the darker colors can be unstable.
