Well no, it doesn't. They still use filler

I had a granite woprktop installed. They glued it together with epoxy
and isued a filler to make it neat, because the epoxy is a finite width
and has to be a finite width


Okay. When i first installed stone work surfaces back in the 1980s that
would have been standard practice. Templating was done by fitters with
hardboard and a jigsaw and you needed gaps all round for tolerance
anyway. The joins often cracked because of normal movement of anything
and everything, imo especially because a standard euro carcase was never
strong or rigid enough for the weight.

When I last installed stone worksurfaces about 15 years ago if you had
any sense you had the granite prepared by a yard with massive cnc
machinery. They would make a digital template with a pointer arm
attached to a laptop on a tripod and you could assemble some joins so
closely that a mere smear of silicone was enough to squeeze out and seal
the joint.

When you left the site the join was seen as feint line only. The
carcases were still crap though, and everything still moved when the
heating came on.
