What's the difference between mortar and grout?
The mortar I'm using for my ceramic tile in the shower (on Durock) is
Versabond (got it at the Borg), grey color. It's made from cement, sand,
and a latex or polymer modifier (the bag's down'stairs; not sure which
The grout I am considering looks to be made from the same ingredients,
though I'm not sure about the proportions.
Is there any special reason the mortar and grout are separate products?
Does the "grout" have some special compound or property that makes it
better as a grout?
