Using thinset mortar as grout

09.08.13
i am working on a tile project for a tub surround. I am using 4x4 tiles with a very tiny grout line. Can I use the mortar/thinset as the grout since the lines are so tiny? I know the grout line has to be sealed when finished. Thanks in advance for sharing.

    Thin set is a bit different than grout. Fine grout lines should be done with "non-sanded" grout ( up to 1/8") for joints larger than this sanded grout is stronger and less prone to cracking.

    Negitive. Like said above, use unsanded grout. You will not like the result with thinset.
