So next step in the Kitchen remodel is to tile a backsplash.

Solid Surface countertop fabricated and installed. Went well, gap in
the back to the wall is flush most places to a maximum of 1/16" in a
few, and there is no SS backsplash coved or otherwise. Plan is to
tile a backsplash wall from the counter top to the bottom of the top
cabinets/windows/ vent hood. Tiles will be 3/8" proud of the wall.

Plan to leave a 3/16" gap between the tile and countertop and use a
color matched (to the grout) sanded caulk at that point. Using MAPEI
grout and keracaulk which is an acrylic caulk.

Would there be an advantage to precaulking the wall/SS joint with a
silicone before the start of tiling to get an additional water
protection seal or would this be an uneeded step or possibly a
negative.

silicone at the edge of the SS won't hurt and will provide a backup in
case the grout/caulk fails. however, that backup is only as good as
the sealer on the wall- water goes right through drywall. if the
drywall has a good coat of paint that'll help.

best thing is to do a good application of the caulk in the first
place, then keep it maintained. water leaks into your cabinetry tends
to make a mess....
