Good to know! That's one thing that's deterring me from that type of flooring but what is caulk lol!!!!!
Some sort of filler, putty or silicone??
It is a type of filler similar to the silicone used to seal around sinks etc, but your flooring person should try to get the colour to match your wood panels as closely as possible. At a normal glance, it is not noticable so makes it look as though the flooring sits flush against the benchtop. Often the caulking gap isn't very large.. a few mm to allow for expansion / slight movement of the floor boards.
