Hi all

I have just bought some ceramic floor tiles, sandstone (or limestone?
can't remember) grout and adhesive. The adhesive is grey. My tiler
(sorry, no time to DIY this one...) tells me the adhesive should be
white or it will show through. This sounds strange to me, but is he
right?

TIA

Greg

Marble can be translucent and will show adhesive especially near to the top
of the grout joint. If a serrated trowel is used to spread adhesive then the
tiles can appear to be striped later on

With sandstone it's very hard to remove traces of adhesive residue. If only
a small bit is accidentally put on the surface it is near impossible to
remove (can be sanded off). White adhesive is not so noticeable in this
situation. A good policy is to pre seal the stone surface.
