I have to repair an area that's tiled above the shower/bathtub. The
adhesive/grout that I'm using is pre-mixed and the choices are sanded
or unsanded. It's the first time I've worked with this stuff and I
don't know what the difference is between the two but suspect it has
something to do with the finish of the grout? Thanks.
*Please REMOVE the obvious for my correct email address*
Unsanded grout is white portland cement (plus pigment if colored, possibly
polymer fortifiers), which shrinks when curing, and will thus crack in
joints wider than about 1/16" or so.
Sanded has fine sand aggregate, which minimizes shrinking. Also slightly
rougher texture and a bit different to finish.
